How to Buy Spa & Hot Tub Parts

April 22nd, 2013 by


Hot Tub parts for DIY spa repair
If you are a Do It Yourself type of spa owner, (and most of our customers are) – you’ve probably seen our huge selection of parts for spa and hot tubs.

Spa Parts are my favorite category of spa stuff that we sell, probably because it’s a bit more challenging to know the intricacies of spa parts. We found out early that to sell spa parts, you have to have people in the call center that understand such things. Our tech support staff actually know how to repair spas and hot tubs.

Spa and Hot Tub parts are something we understand very well at Hot Tub Works. Our staff is trained to help you select the proper spa part, and our inventory investment means that we likely have the part you need, when you need it – often shipping the same day.


How to Order Spa Parts

Spa and Hot Tub replacement parts

On, we have designed a logical spa parts storefront. We don’t ask you to search by sku, or p/n. Instead, we have broken down our spa parts into 12 logical categories, shown right. These spa part categories represent different systems of interconnected equipment or parts – so you can find what you need fast.

Another way we made parts buying simpler was to throw out the schematic! They can’t be displayed clearly anyway, and with thousands of parts to list, it gets real confusing, real fast.

Instead, what we have are pages of similar parts, with thumbnail images – to quickly spot the correct replacement part for your spa or hot tub. We have 37 pressure switches for instance, all listed on one simple page, with detailed descriptions, measurements and an image that you can enlarge to see more clearly.

Most web users are very visual, and using high quality images in our parts department helps our visitors to feel confident that they’ve chosen the right part. This saves us both money and hassle, in shipping parts back and forth.

Other spa parts websites have black and white parts images that look like they were taken in the 19th century! Instead, we decided to do something different, and 5 years ago, launched a parts image improvement program; completed in early 2012.

Some of the other guys have out of date parts databases, selling items that have been obsolete for 10 years. They can’t get the part, but yet they take the order as though they can. A week later, you find out that the part is no longer made, and without a substitute available.

Instead, We continue to add to our spa parts selection every year, as new spas and new spa products are introduced and clean up the database of NLA (No Longer Available) and OBS (Obsolete) spa and hot tub parts. And, when there is a generic replacement, or a similar substitute, we code that into the database, so you know what the options are. And, our website never displays obsolete or unavailable spa parts.

Spa Parts Technical Support

spa-repair-forum-guy-smOur spa and hot tub technical support staff can often help you identify the correct spa part, or verify that your troubleshooting process was logical and correct. We can’t guarantee that the spa or hot tub part you are ordering is the one that you need – we’d have to come to your house and perform a spa diagnostic to be sure!

We don’t make house calls, but you can call us anytime to speak with one of our spa techs about your symptoms, diagnosis, and the parts or supplies needed to make a successful spa repair.


I hope you like our Spa Parts Department – we’ve spent a lot of time designing the most user-friendly and complete online spa parts catalog.

Sundance Spa Pumps and Jacuzzi Pumps

June 3rd, 2011 by

Sundance Wet End



We are now offering a new line of wet-ends called the Piranha that have 8 mounting legs instead of the typical 4 leg style. This will allow you to clock the wet-end into 8 different positions including those 45 degree angles that Sundance and Jacuzzi brand spas used on their models for a number of years.

The wet end for this pump can be adjusted to all these positions, so you can more easily make a replacement to the volute of your spa pump. Reducing the number of 90′s is always a good idea for decreased resistance in your spa system.

Hottubworks Spa Community

May 6th, 2011 by

One of the most useful but underutilized parts of the site is the Spa Community section. This section could be found on the home page of on the left side highlighted in blue or there is a link to each section below:


Hot Tub Tool Box

How to Videos







Under the Hot Tub Tool Box section you will find helpful articles and walkthroughs on chemicals and installation of various hot tub parts including pumps, equipment, etc.

Under the How-to-Video section there are instructional videos on how to turn a wet end, install an equipment pack, etc. and there are also instructional videos and informational videos on a majority of the major items on our site.

One of the best parts about this section of the site is that some of the videos actually are demonstrated by our staff, including an information video on pre-filters told by me.

The forum section is helpful to find answers to questions that aren’t available through videos or to find answers to questions during our off hours.

The blog – well, you know about the blog – over 300 articles of interest to spa owners.

Also, as always, we are available by phone if you ever want to discuss any additional questions that you may have. I hope everyone has a great weekend!!!


Testing Hot Tub and Spa Sensors

April 15th, 2011 by
Balboa Spa Parts Spa Sensor, Balboa M7, LE, Valu Heaters, Acts as high-Limit or Temperature, 12 inches long

How to Test Spa Sensors for Continuity

With your electrical test meter set to 100k ohms, test the green and black wires for continuity.

Depending on the temperature it will give you a value. It is based on a 10k ohm resister. At 77 degrees it will read 10k ohms. As the temperature rises it will have a lower resistance and as the temperature lowers it will have a higher resistance.

Generally, all of the spa sensors will read 10-12k at 70 to 80F for resistance. If your readings are much less, this can indicate a break in the “Continuous” circuit, power not flowing through properly. is helping our customers’ save money

March 28th, 2011 by


Here at hottubworks – we want to help our customers’ save money any way we can. One way we do this is by suggesting less expensive alternatives to maintain your hot tub.

For example; Replacement Spa Filters can be expensive. Especially when you feel stuck buying an OEM filter. Many spa manufactures’ tell their new spa owners that they must buy the OEM filter. Big secret… this is not the case and there is a cheaper way!


I was speaking to a new customer today who has been using the Eco-Pur filtration system (This is a two part spa filter system which can be very expensive). I suggested she use a one piece replacement cartridge filter instead of the two piece Eco-Pur and purchase a mineral cartridge like Nature2 separately, which can be placed inside of the one piece substitute . This combination will do the same thing as the Eco-Pur and save her lots of money! She was so excited.

We can sell you the OEM filter cartridge if you prefer, or if you are looking to save up to 50%, consider a quality replacement spa filter. They are constructed the same, with the same weight and density of fabric,  just without the designer name!

Call any of us here in customer service for suggestions on how you can save money! We love to help!


Winterizing a Spa or Hot Tub

March 25th, 2011 by

How to winterize your spa or hot tub

Blow Out the Spa Pipes

If you plan on draining your spa or hot tub for the winter, be sure to use a wet / dry vac to suck out any residual water in the plumbing lines and equipment.

Water will expand about 9 times it size when it freezes and will easily crack plumbing fittings, manifolds, and spa pump wet-ends.

To remove water from spa or hot tub pipes, place the vacuum nozzle over the jets, suction fittings, filter plumbing, and equipment to quickly remove the access water and prevent a huge repair when Spring comes around. You can make special hose attachments by using various fittings, and duct tape, to make the best seal against skimmers, spa jets and pumps.

You can also use the wet dry vac as a blower, to blow out the spa pipes. Connect to your skimmer pipe to blow air through the spa pack. Turn on your spa blower while you are blowing out the hot tub pipes. Move the vac or blower, around to different parts of the spa, to try to get air into every possible area.

This is also important to prevent standing water from growing bacteria inside of the pipes. Keep blowing air through all of the spa jets, until all of the moisture has been blown out of the pipes and equipment.

For this reason, it is also recommended to use a Spa Purge product before draining the spa, to clear the pipes and equipment of biofilm bacteria. We have two excellent hot tub pipe cleaners – Rendezvous Spa Rinse or Leisure Time Jet Clean.

To complete your hot tub winterization, remove any drain plugs on the pump and filter and open the drain valve all the way. Get the last little bit of water out with a sponge and bucket.

Shut off the power to the spa, so the pumps don’t accidentally turn on while the hot tub is winterized.

Secure your spa cover for winter with Wind Straps if you have high winds. Use the Cover Cap, to protect hot tub covers from weather all winter long.

Identify Your Spa Part or Hot Tub Part

March 24th, 2011 by

spa pumps and motors


One of the hardest things about selling spa parts for the spa industry is that there are 1,000s upon 1,000s of spa parts from all kinds of different manufacturers. Because of this, it has been very difficult to have all of those parts listed on our site.

In most circumstances, however, we can get you the spa part you need, even when you can’t find it on our website, or even on any website.For example. most Hot Springs, Sundance, Jacuzzi, and Balboa parts aren’t listed on our site but we have extensive catalogs and databases we can use to locate these parts for you.

Another place on our site that doesn’t always have every part listed is the Spa Jet section. Most jets come in a variety of colors and textures. Because of that we don’t have the ability to have all of these jets on our site but if you happen to be in this section and find a jet that looks similar to yours but perhaps isn’t the right color don’t hesitate to call in or send us an email. Most likely we will have the jet that you need available.

We can even obtain parts officially de-listed as Obsolete, when stock still exists in distribution. Many times, a comparable part used and made by a different manufacturer may work for older, de-listed and obsolete spa parts.

And then there are just those hot tub parts that are from smaller manufacturers, from very old spas or maybe you just don’t know where to look. The best thing to do in those situations is to email us a picture along with the measurements and any numbers that happen to be listed on the part. From there our experienced technicians and staff should be able to match the part for you.

So again – if you’re looking for a hot tub part, no matter how rare, or difficult it is to find – we are here to help you find the correct spa parts – fast!


Titanium Heater Elements and Ozone Seals

March 11th, 2011 by

Some spa and hot tub manufacturers are offering Ozone generators and/or Salt Water systems to sanitize the water. Although beneficial to water quality, salt and ozone can be detrimental to equipment like standard heater elements and standard pump seals.

To combat this I suggest you use Titanium heater elements and Salt/Ozone pump seals; which are more resistant than the standard versions to the corrosive effects of ozone and salt.

Flothru Heater Element

These heater elements are more expensive, being made from Titanium and all… but if you’re replacing a standard element every 1-2 years, there can be a quick payback in a few years. The ozone grade pump shaft seals are only a few dollars more than standard grade.

So, if your spa heating element look deteriorated and corroded, and you use salt and/or ozone to sanitize, my recommendation is to replace with a version that can withstand the salts in the water.

If your shaft seal is failing, and you use ozone in the water, look for a softening and puckering of the rubber portions of the shaft seal, or possibly corrosion on the spring portion.

Great Customer Savings for Spa Parts!

March 10th, 2011 by

Balboa Spa Parts Spa Control - VS510SZ Retro Kit

I spoke to a customer today who received a quote from their local tech to replace a spa circuit board for about $525 just for the part! We had the same circuit board available for $229.99.

If you guessed that this customer was very excited, that would be an understatement. He was thrilled! At first kind of stunned, but thrilled on cutting the cost in half! His words were something like, “Thanks for saving my life, Scott.”

It almost made me want to change my voice mail to,”Hi! My names Scott! I sell hot tub parts and accessories, and I can save your life!” But how that Larry H. Parker Commercial sounds, with Intensity!

So, thank you stunned, yet thrilled customer.
Tub On!

Testing Spa or Hot Tub Heater Elements

March 3rd, 2011 by

Spa Heater Element testing


Good heaters elements between 4.0 and 5.5kw should have the following results:

* 9-12 ohms of resistance
* good continuity
* draw 15-25 amps at 240v

You test the element by using an Ohm meter, or any multi-meter will work also. Just place it on Ohms, at 1000, and place your test leads on each of the terminals (power to spa heater should be off). As mentioned above,  a measurement of 9-12 Ohms of resistance usually indicates a good element.

To test for voltage, use an Amp meter, and use your test leads to measure the amp draw for the element. Excessive amp draw indicates a bad element, and no amp draw indicates that no power is reaching the terminals.

Poor spa chemistry can harm your spa heater elements, as can operating without water flowing over the element (which the pressure switch is designed to protect against).
