Hot Tub PVC Fittings and Repairs

Many times PVC glue will be required to complete a hot tub repair. Often a PVC primer or cleaner is used first on the parts to be connected.

A complete PVC repair kit can include various standard fittings, connectors, ells, tees, unions and other PVC plumbing parts.

PVC glue (usually the blue glue that sets fairly quickly or other medium or heavy bodied type of PVC glue), either pipe cutters or even a hack saw.

When making a PVC plumbing cut into hose or pipe, be sure the cut is even, straight and does not have PVC fuzz on it.

An applicator is usually attached to the lid of the PVC glue so it already comes with it. Similarly this applicator is also on the PVC cleaner. Apply with a smooth circular motion all the way around the joint to be connected.

For a solid connection, push the two parts together and give a slight twist to assure smooth distribution of the glue. Then hold for at least 30 seconds to a minute to assure a good bond is taking place without moving the connection.

PVC Fittings Size

Hot tub PVC fittings are referred to by their diameter. The most common PVC fittings used in modern day hot tubs are 1 1/2 inch and 2 inch plumbing sizes.

The actual outer diameter of the PVC connectors is usually somewhat larger so that the inner diameter is about the correct size. For example a 2 inch connector may actually be 2 3/8 inches in diameter.

Since this is standardized though, it is enough to know to order 2 inch PVC fittings to connect 2 inch hose and pipe, 1 1/2 inch PVC fittings to connect 1 1/2 inch hose or pipe etc..

Hot tub connectors are available in many standard pipe sizes and in different configurations and shapes.

PVC pipe dimensions are usually written on the pvc hose or pipe.

Other hot tub plumbing parts include adapters that can change the diameter of the pipe run from one width to another, and valves that can be used to shut water off to certain parts of the spa - mainly to isolate components such as pumps and heater from the rest of the spa to facilitate repair without having to drain the spa.

Some hot tubs also have air plumbing including air manifolds that route air from the spa blower to air injectors or air jets.

Hot Tub PVC Fittings and Connectors

Spa FragrancesHot tub hoses and pipe are interconnected with pvc fittings, manifolds and connectors to route water from a single pump to multiple jets and destinations within the spa including waterfall jets, whirlpool jets and other water features.

Most recent model hot tubs use a manifold plumbing system for a more even distribution of water pressure to the individual spa jets.

In the case of a hot tub leak, jets and pvc fittings need to be examined and replaced as needed to repair the source of the leak. From a cracked water manifold due to perhaps having left water in a drained spa sitting out in freezing weather, to a stress crack in any part of the plumbing, water leaks can quickly be repaired once they are identified by getting the appropriate PVC connectors, pipe and glue.

Most often, the spa needs to be completely drained when undertaking a PVC repair and the joints should be dry before applying PVC glue.

Other plumbing parts include air knobs and water knobs that are part of the air or water valves which can be regulated from within the spa to control flow.

Vinyl clear tubing is often found in the air lines of spas that have blowers. Some other manufacturers also use clear tubing with clips in place of glued plumbing, so in that case with a new hose and new clips, these type of connections can be repaired without glue.

Suction fittings are those that are found near the bottom of the spa footwell. They have a protective screen to avoid debris and entrapement. Water is pulled into the suction fittings by the pump and pushed back out to the plumbing which in turn is routed to the spa jets.
