Spa plumbing parts. This is going to be a long post, as we have 12 parts categories to go over, so settle in.
This post will help explain each spa plumbing parts sub-category in more detail, so you know how and when they are most useful.
There are many specialized parts in the plumbing category, and parts used only on certain spas and hot tubs, and many parts which are universal.
Spa Air Controls
Air controls are the knobs on the side of the spa that are used as air intakes. Some spas have several air control knobs, which control the amount of air intake (and thus air output) for a certain group of spa jets, or a particular air manifold. It acts as an air valve, to allow the spa user to dial in the perfect mix of air to the water stream, to increase the action and pressure from the spa jets.
We have over 35 different spa air controls, from G&G, Hydro Air and Waterway. They vary by the S hose connection size, and the hole size on the spa. If you’ve managed to lose or break one of these spa air intake knobs, see our selection of spa air controls.
Spa Air Injectors
Spa air injectors, or maybe you call them bubblers or aerators in your spa, but this is where the air comes out, not mixed with water. Common on the floor or on lounge portions of the spa. You can replace the air injectors in your spa if they have become broken or missing parts, or you are renovating a spa and adding new or additional air jets or larger capacity jets to your spa or hot tub.
We have over 25 different air injectors, from Air Pro, Hydro Air and Waterway. Air Pro has a model with the Backstop, a check valve that prevents water from entering the air line. Similar to air controls, the main difference between Air Injectors are in the air S hose connection size and the hole size, or the diameter of the hole through spa shell.
This section of our spa plumbing department is stocked with sealants and bonding supplies for making PVC repairs with our Heavy Duty PVC cement, or fastening replacement air injectors, water jets or spa light rings in place with an underwater silicone adhesive. Silicone is also useful for making small leak repairs around the skimmer, air hoses, or on the spa shell, sealing up around leaky jets and fittings.
In the Sealant department, we carry 5 types of hot tub silicone by BOSS to allow you to affix and seal up just about anything on your spa. We also have spray blue RTV gasket maker for pump gasket problems, silicone Grout to use on tile and around spa fittings, and Mr. Sticky’s 2-part underwater epoxy. All in our spa sealants section.
Spa Air Buttons
Spa Air Buttons are used to activate the spa blower, lights or jets. They are a safe way to activate a electronic switch when you’re sitting in a tub full of water. Spa air buttons are fairly reliable, but some may fail after many years of use, or become sticky. Like air controls and injectors, replacement air buttons will match up to your current air button by the hose size and hole size.
You can also match up current spa buttons by appearance. We have over 35 spa buttons, in all colors – gold, silver, black, white, taupe, from nearly 10 manufacturers, including Len Gordon, PresAirTrol and Tecmark. Your spa manufacturer likely used one of these specific air buttons, or we also have a universal button on our spa air buttons page.
Spa Drain Covers and Plumbing Fittings
We have over 40 Spa plumbing fittings, like sweep elbows, 45’s, 90’s, connectors, reducers, tee fittings.Use these fittings to make repairs or renovations to your spa. Freeze damage repair to a spa will usually involve some plumbing fittings, repositioning equipment, or re-routing your spa plumbing . When plumbing PVC on a spa, be sure to use primer on the pipe and fittings before applying a heavy body PVC cement.
Half a dozen VGB compliant spa drain covers – it’s very important that they are secured to prevent entrapment. Modern spa drain covers or suction outlets have many small holes and improved flow characteristics to make entrapment unlikely. Missing spa drain covers should always be replaced and firmly secured, with both screws.
Spa Flexible PVC Pipe and Air Hose
This department needs little explaining. We have flexible PVC ‘flex pipe’, in sizes from 1/2″ to 2 inch, sold in long rolls, or by the foot. We just slap a FedEx sticker on the roll of pipe, and ship it without a box – never had a problem. We also carry the clear flexible hose that is connected to air switches or used in air systems.
Spa air hose is sold by the foot, and available in diameters from 1/8″ to 3/4 inch. And, those little hose clamp clips, that always seem to get lost? We have them also, in two sizes.
Use spa flex pipe when you are fixing major leaks or renovating a spa shell. Spa air hose can be damaged by rodents or heat sources. Whatever the issue, we have your spa flex pipe and spa air hose for small or large repairs.
Spa Plumbing Manifolds
These are some of the most interesting contraptions I’ve ever seen. They look like props for a science fiction movie. I keep saying that I’m going to make a lamp out of one of these, one day. Spa manifolds are used to split the water and air into several smaller ports attached to pipes and hoses that go to different water jets and air injectors. They are used for air, or for water, and connect to either PVC pipe or clear air hose and reduce from 2″ or 1.5″ pipe, down to 3/4″ or less.
We have over 50 different manifolds for unimaginable uses. You can plumb in 12 new jets into your spa or hot tub, of fix freeze damaged spas with these manifolds. Maybe you can make a lamp, or something else useful out of these spa manifolds.
Many above ground spas don’t have a skimmer similar to a pool skimmer, with a basket and weir. Many spas have a grate, which covers a throttled suction fitting, that slowly draws water from the surface. More or less effective. Other spas may have the more traditional type of skimmer. Either way, your skimmer grate, basket and weirs needs are covered.
We also have entire new spa skimmers, the Hayward SP1099 front access skimmer used on many backyard spas and hot tubs, or can be retrofitted to outdoor spas and tubs that need more skimming action.
Spa Plumbing Unions
I’m not talking about the Brotherhood of Plumbers, local 454 – no, here we have connectors for spa pumps and filters that allow you to remove the equipment for service with unions – pipe connectors that can be easily removed. Unions can crack under pressure or from freeze damage. They can also overheat and melt, or if doing considerable plumbing modifications, you may need to replace the unions.
We have union nuts, o-rings and adapters. Over 35 unions available in sizes from 1″ to 3 inches, in every configuration imaginable. Specialty spa unions too, such as reducing spa unions, or barbed hose connection unions. View all of our spa unions.
Our final spa plumbing parts sub-category, is also our largest category, of spa directional valves and check valves. Over two dozen slice valves, aka guillotine valves, by Magic and Valterra. We have diverter valves by Jandy and Waterway, and the hard to find Ortega valves with the iconic brass handle. In this section you’ll find check valves for air and water as well. Valves help control the direction of the water flow, and check valves allow flow to pass through in only one direction.
Valves may need replacing for various repairs, or to replace a defective valve. Check valves also don’t last forever. For this reason, we also stock some of the most popular spa valve parts. Check us out when you need new spa valves.
That’s Ten categories of spa plumbing parts and fittings (I skipped two of them!). Just about everything you need to keep your spa or hot tub humming along.
