Spa & Hot Tub Safety – Drain Cover Recalls

January 22nd, 2015 by

RISING-DRAGON-DRAIN-COVERYour spa drain can kill! Numerous entrapment injuries have occurred, where the powerful suction of a spa drain has trapped persons under the water. They are either suctioned onto an unsafe drain cover, or have hair or hands stuck in the pipe, when drain covers go missing.

The number of entrapment fatalities over the years prompted the CPSC and other agencies to demand safer standards for pool and spa drains. Commercial spas are now required to have dual drains set far enough apart to prevent entrapment, and drain covers must be of a safe design, to diffuse the suction and prevent entrapment.

In 2008, manufacturers produced redesigned drain covers which would diffuse the suction around the top and sides of the drain cover, reducing the chance of entrapment. Most of these early spa drain covers were voluntarily recalled, in 2011, as not meeting rate of flow requirements.

Here’s a summary of some of the more common spa drain covers that have been recalled. Check your own spa or hot tub to be sure you don’t have these drain covers, and also check that your drain cover is securely screwed in place. Missing or broken drain covers are more dangerous than an unsafe drain cover.

spa-drain-covers-recalled

recalled-drain-covers

Most portable, aboveground spas are plumbed in such a way that the drain and skimmer are connected to the same pipe. This design is inherently safer, because if you block the drain cover, it will automatically start sucking more from the skimmer. However, this does not reduce the danger of entrapment. Be sure that your spa drain covers are safe, and secured in place at all times.

Never use a spa or hot tub without safe drain covers in place – and if your spa has separate spa and main drain pipes, as many inground spas do, a dual drain system should be installed, far enough apart so that coverage of both at the same time would be unlikely. For added protection, install an SVRS (suction vacuum release system), to automatically shut off the pump when suction or vacuum pressure increases (indicating that something is blocking the drain cover).

Spa drains or suction outlets can be dangerous – check that your system is safe by contacting the manufacturer of your drain cover, and by having your system certified safe, or modified to be safe.

Spa & Hot Tub Error Codes – OH, OHH, OMG

January 6th, 2015 by

balboa-control-OH-errorIn our series on spa and hot tub error codes, we turn our attention today to the HOT messages that your topside control may be trying to give you.

OH, or OHH, or OHS (Overheat) all mean that a temperature sensor has detected unsafe water temperatures of 108° – 118° F, and your spa is in an emergency cool down mode, shutting off the heater, and turning on circulation pumps and blower to help dissipate heat.

Open the spa cover to allow excess heat and steam to escape. The spa obviously should not be used when OH or OHH is flashing on the topside control; as the water could be scalding hot for several more minutes. After the water cools, a high limit switch may be need to be reset on some spa packs; look for a red reset button. Press any topside button to reset a digital spa after the water has cooled to 100° F.

What causes a Spa to Overheat?

Low Water Flow (LF, FLO), is the usual cause of an overheating (OH, OHH) spa or hot tub. When water doesn’t flow fast enough through the heater, it removes less heat, and the temperature of the water increases. Eventually, the temp sensors or high limit switches will detect the increased water temperature, and shut everything down. The causes of low water flow in a spa include:

  • Dirty spa filter cartridge
  • Closed or partially closed valves or jets
  • Pump has an air lock, or has lost prime
  • Low water level in spa, skimmer sucking air
  • Spa drain cover is obstructed or pipe is blocked

What else causes a Spa to Overheat?

If your water flow is perfectly fine, then you could have a problem with the thermostat or high limit switches used on older spa packs, which could fall out of calibration, or become too sensitive. Digital spas have electronic sensor circuits, which are more durable than mechanical switches, however temperature sensors, hi limit sensors, relays and circuit boards also eventually fail on modern spas.

In most cases, for newer spas anyway, the water flow problem can be quickly remedied and the spa will cool, reset and start again on it’s own. Some panels need a prompt from you to restart. For spas without digital controls, you may need to manually reset the high limit switch near the heater housing.

Spa Overheating Troubleshooting Flow Chart

Here’s a Cal Spa troubleshooting flow chart that has some other possible triggers of seeing OH, OHS, OHH or HH blinking on your spa panel. Open the spa cover and let the spa cool down for 10 minutes, then touch the control panel to reset the circuits, or push a red reset button on air systems.

cal-spa-OH-OHH-OHS-HH-error-code-trouble-chart

OH, HH or HOT trouble codes, or a hot tub overheating is not usually a spa heater problem - it is almost always a flow problem, and when it’s not a flow problem, it’s a bad temp sensor, high limit or a stuck relay.

Here’s another Cal Spa troubleshooting flowchart for spa error codes OH, including testing the spa heater element for excessive resistance, done with the spa heater and all systems powered Off, and only by someone qualified to test safely.

cal-spas-OH-spa-heater-code-trouble-flowchart

So, the next time your spa throws you a OH, OHH or some other Overheat error code, you know what to do. Clean or replace the spa filter, open all the jets and turn the pump on high. If you still have problems, check over your temp sensor and hi limit circuits for wire or plug or sensor problems.

Baby It’s Cold Outside: Winter Hot Tub Tips

December 29th, 2014 by

spa-during-winterFor many spa or hot tub owners, winter is the perfect time to enjoy a hot soak in your outdoor tub. Here in Southern California, the winter temperatures rarely dip below 50°, which hardly qualifies as cold for most of the country.

If you live in colder climates, where 50° would be a winter heat wave, you can safely (and sanely) enjoy your hot tub. In winter, the air is crisper and the stars are brighter, and even if there is snow all around, it’s the perfect time to enjoy your hot tub with family and friends.

Here’s some tips to help enjoy your hot tub, during the holidays, and all through the winter.

 

1. Wear a Hat

For women (or men) with long hair, wearing a hat helps to keep your hair dry, which will help to regulate your body temperature, and prevent catching a chill while using the hot tub. Not only important for keeping your hair dry, we all know that 70% of heat is lost through the top of your head – so break out a ball cap, knitted cap or even your ten gallon Stetson®.

2. Wear Face Moisturizer

Skin cream, or hand lotion will help protect your face from bitter winter winds, which can be drying from low humidity. A layer of moisturizer (or even suncreen) will keep your skin from drying out, and keep the moisture in your skin. It also forms a barrier over your pores, to reduce absorption of spa chemicals that may be released at the surface of the water.

3. Wear Sandals or Slippers

Most outdoor spas are at least 10 steps from the door. And unless you have a red carpet runway from the doorway to the spa, slippers or sandals will help keep your spa clean, and keep your tootsies warm and dry, as you make the mad dash to the hot tub. Surfaces around a spa can also be slippery, so wear something on your feet to keep from becoming a slip and fall statistic.

4. Warm Towels

My favorite spa accessory is a towel warmer, which my wonderful husband gave me (us) as gift on my last birthday. It’s a small box, about the size of a micro-fridge, that holds 2-3 towels, always toasty warm and ready for use. Don’t have a towel warmer? No problem, pop some towels in the dryer beforehand, and store them in a small box just inside the door to the house.

5. Cool Umbrellas

If you have a patio umbrella near the spa, have it ready to pop open in the event of rain or snow. If you wear a hat, you may not need to use an umbrella, but if not, it’s nice to have a large umbrella or small parasol to keep winter weather from raining on your parade. Hold on tight in high winds, and if a rare winter thunderstorm develops, it’s best to head indoors.

6. Hot Drinks

In warmer outside temperatures, nothing is as refreshing as a cool beverage (I like infused waters), to help regulate body temperature. During the winter however, we like to make up a batch of Mexican hot chocolate, and pour it into an insulated coffee carafe, to keep it warm. Coffee mugs are perfect for the liquid chocolate; just be sure not to spill any in the tub!

7. Spa Covers

The colder the weather is outside, the faster your spa will lose heat. Spas without an effective cover will have trouble maintaining the heat during freezing temperatures, and may not recover fast enough after losing ten degrees while the cover is off. If your cover is struggling to keep the heat in, consider that it may be time to buy a new spa cover, and perhaps also investing in a floating spa blanket.

Don’t let the cold weather temperatures drive you indoors! Enjoy your spa or hot tub all year round, just remember to limit your soaks to 20 minutes, and enjoy your soak without alcohol or drugs, which can be dangerous.

Solar Hot Tub Heaters

December 22nd, 2014 by

spa-solar-heatersSolar Hot Tubs are all the rage now for off the grid homes and campsites, or for anyone who wants to operate a spa or hot tub in an eco-friendly way.

Can a solar pool heater be used to heat a spa? You betcha! And it’s a simple Saturday project. Spa solar heaters can heat up a spa to over 100° with just 6 hours of sunshine – ready to use when you come home from work!

I have a friend with an inground pool and spa, and a solar pool heater – his spa is 104° in under 30 minutes – during sunny daylight hours, of course. And,…there’s not much heat in winter, but you can get 3 seasons with a hot tub solar heater!

Your hot tub cover will retain the heat from a solar heater until well into the evening, and if needed, you can use an alternate spa heater or hot tub heater for night hot tubbin’.

 

How to install a Solar Hot Tub Heater

1. Location of Solar Panels: The first thing to think of is where and how the solar panels are going to be mounted. If you have full sun, all day long, you could just lay them on the ground, but for most folks, mounting them on a roof or rack, at a 30-45° angle works best. A rack can be built of angle iron or lumber, topped with plywood or plastic and painted black. You can also hang them on a fence. Choose a spot that will get at least 6 hours of daily sun; a southern facing direction is best.

2. Buy a Solar Pool Panel: A single 4′ x 20′ solar panel, a total of 80 square feet, is a good size for most spas. There are also 4′ x 10′ panels, but they are priced higher per square foot of panel. 80 sq. ft. of solar panel will heat spas under 500 gallons to over 100° during the day, and be ready to go for the evening. If you want to heat the hot tub in under an hour like my friend with the pool/spa, you’ll need 4-5 of the 20′ solar panels.

solar-heater-all-rolled-up3. Installation of Hot Tub Solar Panels: Solar pool panels are polypropylene mats of small black tubes with a continuous backing, so they absorb more heat than black hose DIY solar spa heaters. Inside the box will be two 2′x20′ solar panels, end caps, pipe adapters, mounting kit and a 3-way diverter valve. Secure the panels to the location securely so they are protected from high winds, animals and tree branches. Attach the end caps, and run PVC pipe from the panels to the plumbing line of the spa.

4. Plumbing a Spa Solar Heater: This part is custom for every spa or hot tub, but essentially you connect the plumbing from solar panels to the spa. A 3-way diverter valve will allow for adjusting the flow rate, and for shutting off the solar panels completely. Other items needed for plumbing beside the pipe include some directional fittings (90′s or 45′s) and couplings to connect lengths of pipe. A check valve is needed just before the heated water comes back into the spa plumbing, to prevent water cycling.

Other Thoughts about Solar Hot Tub Heaters

  • A solar controller can be used with an automatic valve turner and temperature sensors to have thermostat control for the solar spa heater, but more importantly, to shut off the unit when conditions are not right for solar, at night or when it’s raining, for instance. This is an extra $325, but is recommended for optimum heating, neither under or overheating the spa.
  • Speaking of overheating, it is possible to overheat the water with a solar spa heater. If you have an electric spa heater, the hi-limit may trip and shut off the spa pump, but at that point the water may already be dangerously hot. Use caution not to heat the water over 104°.
  • As mentioned before, hot tub solar heaters don’t work at night, or when it’s raining or heavily overcast. They drop way off in effectiveness during the winter months, unless you are in the very deep southern U.S..
  • A booster pump is not usually needed for installation on a roof, unless the roof is very tall. If a booster pump is needed these small spa circulation pumps are perfect for the job.
  • For best results, use an insulated spa cover to retain the heat and a solar controller to optimize when the solar panels are used, and to maintain safe water temperatures.

 

sunheater-solar-pool-heater

Hot tub solar heaters work very well in all parts of the U.S. – anywhere that has at least 6 hours of unobstructed sun. For many hot tubs, solar heat is used as a supplemental heater to keep the spa hot during the day, and at night or during rainy periods, the other spa heater takes over.

I wish I could say that we sold solar spa heaters at Hot Tub Works, but we don’t. However, here are some links for solar pool heaters and controllers at Specialty Pool Products, who had the best price on solar pool panels that I could find online.

Hot Tub Pioneers – Baja Spas

December 18th, 2014 by

baja-spas-early-logoA booth at the 1971 NSPI show and the opening of the Dallas-Forth Worth Airport led to the creation of the world’s first acrylic spa.

Baja Spas, based in Tucson, Arizona, founded by Bernie Burba and Ed Price, began as pool builders in Naperville, Illinois, in 1960. Ed Price founded West Suburban Pools, a high-end concrete swimming pool builder, and Burba joined him in 1962.

When the pool builders finally had money in the bank, they expanded into other areas. In 1965 they formed Aqua-Gon, one of the nation’s first pool product distributors, then they opened several pool stores in the area.

In 1971, Baja began producing fiberglass and acrylic diving board stands. They were the first to use these two materials together in the pool business, and patented the process of vacuum forming fiberglass and acrylic. Burba and Price chose the name Baja because it was short and didn’t pigeon hole them into one product line. Also, it was one of their favorite areas to visit in Mexico.

Sales of diving boards jumped, and by 1972, Burba and Price sold their business ventures in Illinois. Burba moved to Tucson to dive into the diving board business. The same year they were joined by Randy Price, currently the President of Baja Spas.

The 1971 NSPI Show

Life changed forever after the 1971 NSPI annual show. Baja Products, displaying its diving boards, found itself next to a booth held by Riviera Spas. Few people stopped by to look at the new diving board design, but the Riviera Spa booth was packed. The two realized that spas represented a timely business venture.

They researched spas and discovered weaknesses in current design and manufacturing of spas and hot tubs. At the time, spas were made of fiberglass covered by gelcoat, similar to boats and pool slides. However, gelcoated fiberglass couldn’t stand the intense heat of spa water, the chemicals used for sanitation and water balance, or bright sunlight. “The gelcoat caused a lot of problems,” Randy Price says. Blistering and cracking were the main problems, in addition to delamination of the two materials, and fading from UV rays.

An Acrylic Spa is Born

Baja however, was already manufacturing an acrylic-fiberglass stand for its aluminum diving boards. “We believed in our acrylic. So we decided to manufacture a spa made of acrylic. Our competitors said it wouldn’t work,” Ed Price says.

baja-spas-logo

The company could not find a sheet of acrylic big enough for a spa. “Manufacturers at the time just weren’t making sheets that size,” sighs Burba. “Finally, we found the only one in the world” that could help them. It was Swedcast Acrylics (now Aristech) in California.  Swedcast had large sheets of acrylic on hand because it was making sheets for the monorail cars at the new Dallas-Fort Worth Airport. Swedcast sold Baja some of these same acrylic sheets, large enough (9′ square), to produce a vacuum formed spa shell.

Baja manufactured it first spas with three employees, and tested them by setting up a few spas in the intense Arizona sun. They also shipped their new acrylic spas to Illinois to test it out in a winter climate. “Those spas today still look like new,” Burba says proudly.

Selling Acrylic Spas

One of their first customers was Phil Horvath, president of Aqua-Gon, the distributor that Burba and Price had founded. Horvath says when he saw Baja’s first spa, it took his breath away. “It was gorgeous” he says. But it took some convincing to sell people on the idea of an acrylic spa.

Horvath held seminars for potential customers to sample the new acrylic spa. “We told them the acrylic was indestructible. We wanted to show them how strong the material was, so we hit it with a 2 x 4. It worked!” Horvath recalls.

Expansion in the 80′s

In 1981, Randy Price opened a new production plant in North Carolina for the company. “We can reach 70 percent of the U.S. population in a few days by truck from that location,” says Price. In 2005 they stopped manufacturing in Tucson, AZ but kept their corporate office and service department. Even now, they continue to ship from both locations keeping transit time for their hot tubs to a minimum. Sales are worldwide.baja-luv-tub

Baja is perhaps best known for a specialty item, a heart shaped spa called the Luv Tub. The company decided to develop this tub in 1974 after Ed Price was looking through a brochure for the Mt. Airy Lodge, a honeymoon resort in the Poconos. One of the suites had a heart shaped red bathtub made of concrete and tile. “Ed Price looked at the photo and said, ‘We can make that in acrylic,’” recalls Bernie. Soon after, the Luv Tub was in production.

After some of their spas were in place for 10 years now, some of the same trouble of blistering and delamination that had plagued fiberglass spas, now began to appear in the acrylic spa shells. Working with the boating industry, a solution was soon found by switching from polyester resins to ester resins. No more gas blisters!

Award Winners

Randy Price and Bernie Burba have received two prestigious awards in the spa industry. In 1992, Randy was honored with the John Silver Award recognizing his technical contribution to the industry in the development of vacuum formed spas. In 1987, Bernie was given the Eagle Award by the Spa and Tub Council of NSPI (now APSP) for his contribution and leadership in the industry.

Today and Tomorrow

Bernie Burba and Ed Price are now retired, but Baja Spas continues operations and a legacy of innovation. Credited with the first acrylic spas in production, they were ahead of their time (by about 10 years), and way ahead of competitors like Cal Spas and other copycat manufacturers. The cost of vacuum forming equipment, and a lack of knowledge, gave many trouble migrating to acrylic production.

Baja Spas continues to lead the field, not only with quality products, but with solid, feel good marketing. At Hot Tub Works, we wish them well in their bright future!

Hot Tub Pioneers – California Cooperage

December 2nd, 2014 by

california-cooperage-adIn the late 50′s, California was (and still is) an area of the country where a spirit of fun inventiveness took root. The first hot tubs were fashioned from wine barrels and olive vats – cut in half. During the 60′s sales grew, but supplies of spare barrels and vats dwindled. By the time the 70′s rolled around, California Cooperage had set up operations in SLO – San Luis Obispo, a cool central coast college town, near Morro Bay.

The first customers were friends, then friends of friends, and after a year, a mail order catalog was produced, and the company began shipping pre-fab hot tub kits of cedar and redwood, according to Beth Hamil, VP of Del Ozone, but on staff as lead engineer in the early years.

“The original fellow at California Cooperage was Cliff Branch, a marketing genius, in my opinion” says Beth. Cliff is given some credit to the sexy image of the California Hot Tub, and many of the ads had racy themes.cal-coop-ad-1979

According to Branch, “it all started when Playboy magazine did a centerfold of a “California” girl in a Hot Tub. Several other magazines and newspapers, more mainstream than Playboy, soon followed with their own articles and pictorials of the “Hot Tub lifestyle” taking place in California. And then an episode of the television show “Charlie’s Angels” featured Jaclyn Smith and Farrah Fawcett in a steamy hot tub, seemed to push it over the top.

“California Cooperage helped to nationally promote hot tubs. Cliff Branch was a wizard of getting onto national TV talk shows. He became an industry spokesperson. I remember him filming programs on “Good Morning America,” sitting in the hot tub with the hosts.”, from Bill Jaworski in the hot tub business at the time.

Evocative and provocative as it was at the time, the use of subtle sexuality was embraced by the public. As Branch told the San Bernadino Courier in 1978, “…there’s a new awareness among the middle class… Back-to nature, getting in touch with your feelings, nudity and sex.”

But the largest publicity stunt ever was probably the pool and spa show, held at Cow Palace, near San Francisco. Although no one admitted to hiring three young women to strip naked and climb into the California Cooperage hot tubs, many had a good idea who was behind it. It made regional and national news, with the commotion nearly shutting down the convention.

early-acrylic-hot-tub-by-california-cooperageCliff Branch partnered with Jim Smith and John King, two local investors, and built a 60,000 square foot sales and manufacturing building. The seventies were good for California Cooperage, and when the eighties were ushered in, California Cooperage began also making acrylic tubs, like the type being made by Jim and Jon Watkins in Vista, Ca – but still using a classic wood frame, barrel style.

In 1985 Coleman Spas bought the company for 10 million, and moved the operations to Chandler, Arizona. They soon stopped making the wood tubs altogether, due to sagging sales and cost and availability of expensive redwood materials. Maax purchased the company some years later, in 1998.

CLiff-branch-in-a-hot-tubCalifornia Cooperage hot tubs can still be purchased today, although they have come a long way from the original barrel tanks used for water storage or wine aging.  Digital controls and a spa pack have replaced wood stoves and a single spa jet. Molded acrylic seats have replaced redwood benches.

They can call it progress, but there’s nothing like a real wooden hot tub. And California Cooperage will ever be known as one of the first companies not only to mass produce a hot tub kit, but export a lifestyle to all parts of the country.

I don’t know what has become of Cliff Branch, I knew him years ago and thought him to be incredibly engaging – the right guy at the right time for a start-up industry like spas and hot tubs. Wherever you are, Cliff – I wish you well, and if you have anything to add to the article – send me an email!

Hot Tub Pioneers – Len Gordon

November 17th, 2014 by

Our story begins here in southern California, in the late 60′s. Pool builders like Len Gordon (1925-1997) were adding attached spas to the gunite pools they were building.

spa-shell-patent-application-US-4142337-A--Interested in how he could simplify spa construction, and avoid the structural problems of adding a separate body of water – he and fellow builder Jack Stangle dreamed up drop-in fiberglass spa shells, similar to the hydrotherapy tanks that Jacuzzi was making.

Len Gordon saw potential in the inground spa market, and set up a manufacturing facility in a rented gas station; soon making several spa shells per day.

Len Gordon’s Fiberglass Spa Shells

The innovation and mass production of a drop-in fiberglass spa shell is often credited to Len Gordon Co., and soon after many other small manufacturers joined in, revolutionizing (or creating) the market for inground hot tubs. As Len told Spa and Sauna magazine in 1986, “The fiberglass shell was a contractor’s dream, all you had to do was dig a hole in the ground and you were just about finished. It cut the costs dramatically over gunite.”

Suddenly, an inground spa was within reach of nearly everyone, being that it was now much cheaper to buy and much simpler to install. Not too many years later, innovative manufacturers like Jacuzzi and Watkins began to create complete aboveground spas, which didn’t require digging a hole in the ground, or hiring lots of contractors.

Len Gordon’s Air Switches

I’m not old enough to remember, but in days gone by, the spa equipment was separate from the hot tub, and you had to climb out of the warm water to activate functions like jets, lights, heater, blower. There was no safe way to control this with electrical switches that were activated from inside the spa.

len-gordon-spa-controlUntil one day in 1974, while driving his truck to a job site; Len Gordon came up with the idea of an air switch, which could be operated from inside the tub. From a Len Gordon patent application:

“These air switches incorporate bellows which are compressed when the switch button is depressed thereby forcing air through a pneumatic tube to activate an electrical switch”

Len Gordon’s Legacy

Len Gordon company received other patents, one for an insulated high voltage switch which could be safely used from inside the spa, and in 1983 a top side control panel that integrated many air controls onto a single panel. The Len Gordon company discontinued spa manufacturing by 1980 and focused on their core products of spa switches and controls. They continued to operate for over 25 years, until Len’s passing in 1997.

len-gordon-ss2After Len’s death, the business carried on, buying a manufacturer of spa packs and controls, Brett Aqualine, in 1998. The Len Gordon company was sold by Len’s descendants in 2001 to Allied Innovations, where the business has carried on to this day.

One of the great “Hot Tub Pioneers”, Len Gordon was also a great guy to know or do business with – and is remembered fondly here in southern California, by many of the founders and friends of Hot Tub Works.

How To Install a Portable Spa Hot Tub

November 6th, 2014 by

deep-clean-your-spa-smSo, you saw our great prices on new spas, and unless this new spa is a replacement spa, you’re wondering what’s involved in spa or hot tub installation.

Whether you install one of our Plug & Play 120V spas, or a full featured premium spa running on 4-wire 240V, requiring an electrician, you’ll need to plan a few things in advance of receiving your new spa.

Spa Fencing

There are two types of fencing needed, safety fencing, to keep people and animals out, and privy fencing to keep out prying eyes.

For safety fencing – in most localities, a spa is under the same or similar fencing rules as apply to swimming pools, in the interest of public safety. Generally, a spa inside of a fenced-in backyard is acceptable. pergola-privy-fenceThere may not be an inspection of the fence in some cases, but still required nonetheless.

Privy fencing provides privacy, also a consideration when installing a hot tub, and also blocks the wind, which can cool the spa, and give you a chill while soaking. Frame your spa with large plants, and a 2 sided lattice fencing, or a pergola or cabana installed around the tub. Outdoor roll-up shades are also popular.

 

Tub Location

A convenient location is best, near the door. The area should be clean and dry (never muddy), and close to power and water. Shield the spa from as much sun, wind and rain as you can, and take care that storm waters will always drain away from the spa.

ezpads-for-spasThe surface supporting the spa must be solid, when full with water, a 6 person hot tub can weigh close to two tons! No wooden decks and certainly no balconies. A level, 4 inch slab of steel mesh reinforced concrete, on top of 4″ of gravel is sufficient in many cases.

Our hot tubs can be sunk into a deck when proper load bearing support is built to hold 150 lbs per square foot. Finally, consider view – both the view of the spa from the house and the view that you’ll have while in the spa.

 

Moving a Spa

spa-kartWhen the tub is delivered to your home, it won’t go any further than the driveway. From that point on, you have to figure out the shortest and safest route to the spa placement location. Professional spa movers use a Spa Kart to transport spas across lawns, over steps or into tight locations within the home. Check for local spa movers or rental shops for a solution, some even rent Spa Karts. Over smooth concrete it’s easy, but when the surface gets rough and uneven, you’ll need something with big tires, to support a spa of 400-600 lbs, along with straps and several hands to help.

 

Hot Tub Wiring

GFCI-spa-plug120V Spas: Most of our rotomold hot tubs are plug and play; 120V spas that plug into a standard, dedicated outlet. Dedicated means that nothing else is operating on that circuit. Plug the GFCI cord into a weatherproof 120V outlet (not GFCI), on a 15 or 20 amp breaker. The outlet should be between 5 and 10 feet from the spa, and no extension cords. 120V spas use less volts because they have smaller pumps and heaters, and few other features.

240v-spa-wiring240V Spas: Larger spas with 4-5 hp pumps and high wattage heaters require a 6 AWG, 4-wire 240V service to the spa, on a dedicated 40-60 amp breaker, with a cut-off switch or sub-panel, and other requirements, as per local electrical codes. They do not plug in like a washer or dryer, but use 4 wires inside of PVC conduit, with the last few feet of flexible conduit carrying the wires directly in through the cabinet and connecting to the spa pack.

Wiring a spa with 240V is not a recommended DIY project. A permit and an inspection is required in most areas, so it’s best to contact a local electrician who is familiar with the process of wiring spas and hot tubs. In most cases, hard-wiring a spa to the home main breaker, and installing a power cut-off near the spa is a $500-$900 job, depending on the length of the run from the breaker panel to the spa, and the route it must travel.

 

Filling a Spa

When the wiring and inspections are done, you can fill the spa, insert the spa filter cartridge.

loosen-the-pump-union-to-bleed-airWhen you first fill an empty spa, and sometimes when you drain and refill the spa later, and air lock will occur in the pump, and prevent the pump from catching prime. Instead of running the pump without water, which can damage the seals, loosen the union nut in front of, or on top of the spa pump just enough to let the air escape, and allow the water to fill the pump. When water begins dripping around the union, tightly up all unions tightly. Open up all gate valves in the system, and you are ready to begin filtering, heating and chemically treating your new spa!

 

Enjoying your New Spa

enjoy-your-spaThat’s the best part, after all the working of selecting, ordering, receiving, moving, wiring, inspecting, filling…now you finally get to enjoy the fruits of all your hard work and money.

Some accessories to help you enjoy your spa more include a spa cover lifter to help protect your spa top, and a supply of spa chemicals and test strips. Spa steps, handrails, and spa cleaning tools are on our spa accessories page – if you’ll pardon the shameless plugs.

Turn up the heat, and enjoy your New Spa from Hot Tub Works!

Winterize a Hot Tub in 5 Steps

November 3rd, 2014 by

spa-winterizationWinterizing a spa is simple enough for the average spa owner to perform, with simple tools and equipment. Winterizing a wood hot tub? It is not recommended to drain a wood hot tub for an extended period, or else the wood will dry out and shrink.

To winterize a wood hot tub, you can follow the steps below, but then plug the lines and fill the hot tub back up with water.

To keep the water from freezing solid across a wood tub, use an air pillow like those used for aboveground pool winterization, or fill several gallon sized plastic jugs, filled 1/3 full of pea gravel or pool antifreeze. Float these in the hot tub to absorb ice expansion. Add spa algaecide or sanitizer to control algae growth and cover tightly.

To winterize a portable spa, one with an acrylic or fiberglass shell, follow these instructions:

1aDrain The Spa

You probably know this drill already, but in this case you need to get all of the water out of the spa – every drop. Open up the drain spigot and roll out the hose, or use a submersible pump (which is hours and hours faster). Shut off the power to the spa before draining and plan your drain – first by making sure the sanitizer level is low, and the pH is balanced. It’s best to run the hose to an open yard, and move the hose often, to increase disbursement. In most cases, spa water is safe to use to water planter beds, trees or lawns, as long as your sanitizer level is under 1 ppm, and you move the hose around often.

2a

Turn on the Blower

Once the water is drained out, you can turn on power to the hot tub, but keep the pumps and heater off. Activate the blower only, and unless you want a fine mist shower, put the spa cover over the tub first. After running the blower for a minute or less, allow the water to drain. If you have air jets in the seats or the floor, turn on the blower again and mop up the mist spraying out with a big towel. Wring out the towel and continue to wipe up any spray that continues to spit out from the small air holes.

3aBlow out the Pipes

This is the part that makes people nervous, but it’s really quite easy. You’ll need a large wet/dry vac, reversing the hose so that it blows air through the hose. Remove the skimmer basket and blow air through the skimmer, thru the filter, thru the pump, heater and back out through the spa jets. Be sure that all of the manual air intakes are open, and that all banks of jets are open. When all of the water has blown out, move the wet/dry vac inside of the spa, and blow air through the jets. You can also reverse the hose, and use suction to suck the water out. Be sure that all lines are open and all water has been removed.

4a

Winterize the Spa Equipment

Remove the spa filter and give it a good deep cleaning, or dispose of it if it has been in service for more than 12 cleanings or 24 months. Open up the union nuts on the pump and heater, to check for any remaining water, and allow it to drain out. When tightening back up, make sure the union o-ring has not slipped out. Look over the system closely, and open any drain plugs that you see on the pipes or equipment, especially those on lower pipes. Keep the spa drain open, in case any water gets in during winter, and be sure to shut off all power to the spa, at the main circuit breaker.

5a

Cover the Hot Tub

If your spa cover is not in the best of shape, invest in a cover cap, or tightly secure a tarpaulin over the spa, using bungee cords to keep it in place during high winds. If your spa cover is in good shape, it still would be a good idea to cover it, to protect the cover and to keep any rain or snow out of the spa. Another good thing to do during a spa closing is to clean and condition your spa cover, using one of our many spa cover care products.

 

~ That’s it! Just 5 steps to close a spa for winter, and a few more additional steps if you have a wooden hot tub. Drop me a line if you have any questions about winterizing your spa or hot tub.

Hot Tub Pioneers – Jacuzzi Brothers

October 27th, 2014 by

Joseph-JacuzziMy wife, of all people, just said “I didn’t know that Jacuzzi was a family name.”  The story of the Jacuzzi brothers, and the origins of the business efforts that eventually became a household name, is simply fascinating, I told her.

Take a look, this is Joseph Jacuzzi, one of the seven Jacuzzi brothers who worked together to create innovations that the world could not live without. “Mmm-hmm” she says as her head tilts to her shoulder.

In his hand, he holds a closed vane impeller, used on their vertical pump design, the one that used the injection pump in the well and a multistage centrifugal pump above ground – and which revolutionized the agricultural well water pump and later spawned the origin of the Jacuzzi whirlpool bath? “Yeah.”

The Jacuzzi Impeller Design created more flow with less resistance, capable of much more lift with less work, than other impeller designs. During the last century, Jacuzzi Bros., inc. patented over 300 designs for impellers, propellers and turbines, for pumps, planes and ships.

jacuzzi-propeller-adThey started with propellers, for airplanes, and patented a very successful impeller, and later designed and built the first high wing monoplane with an enclosed cabin, and sold it to the US Postal Service and to commercial airline operators. They were propeller and aviation engineers before they were ever in the water business.

But, an unfortunate crash of one of their airplanes in 1921, which killed Giocondo Jacuzzi, led to the Jacuzzi brothers directing their knowledge of propellers and air dynamics into the development of impellers and flow dynamics.

jacuzzi-j300-pumpCalifornia farmers during the depression were needing a reliable way to bring up deep water at low pressure, to water crops. The Jacuzzi brothers designed a unique vertical pump design, which is still in use today by many farmers, across the world. It protects the motor from water, while reducing seal problems with the shaft. A multi stage volute, using multiple stack impellers, creates lift and suction from one centrifugal stage to the next.

jacuzzi-j300A scaled down, portable and submersible version of their popular agricultural pump was created for home use, and was found to serve a multitude of industrial and commercial water movement needs, especially for rural Americans. The J-300 pump was introduced in the fifties and became wildly popular for personal hydrotherapy (it’s original purpose) by just dropping it into a hot bath. Many more inventions followed, for marine, agriculture and consumer use.

It’s all about the Impeller

The impeller, which they also termed a “spider” was unique in design and function. From the original patent, US 2424285 A, filed in 1929 “These spiders are of star-shaped contour, having a plurality of ribs across the upper surface, extending from the points of the star toward the center. The ribs are curved to define passages offering minimum resistance to flow of liquid.”jacuzzi-impeller

Jacuzzi was not the first to use a curved vane, but they continued to refine the art with their dozens of patents filed on improvements in impeller efficiency, creating more output with less energy, and with less wear and tear, pump leaks, both common problems of the day.

A Spa is Born

Jacuzzi-spaAs the Jacuzzi company entered it’s third generation of family ownership, Roy Jacuzzi, fresh out of college, champions a new line of products – personal whirlpools, in 1968. In the seventies, this expanded to larger models called spas, with molded seats, pumps, filters and heaters. The determined Roy Jacuzzi traveled thousands of miles at trade shows and county fairs, building enthusiasm for this new lifestyle product, which caught on quite well I’d say. Through the eighties and nineties Jacuzzi Whirlpool sales represented 80% of company wide sales, completely overshadowing the swimming pool and agricultural line of products.

The Jacuzzi Brand

jacuzzi-logoSo yes, Jacuzzi is a family name, (Hi, Honey) – a brand name and not just a generic term for a hot tub. They are credited with the creation of what we call hot tubs and spas, and although the Jacuzzi family has long ago sold off the family business, the company continues to inspire with creative whirlpool and bath design and quality construction.
