Why Is My Hot Tub Leaking?

Most Common Reasons for A Hot Tub Leak

The Pump: One of the most common locations where a leak can arise is the pump. If you're going to check this location, be sure to turn off the power and check under the pump for leaking water. If you find anything wrong in this area, you'll probably need to replace the pump seal or the entire pump.

The Heater: If the pump showed no signs of leakage, then the heater could be a potential issue. The heat assembly manifold—the heater, pressure switch and other componentsare located in this assembly, so if there's a problem with any of these compartments, it's necessary to replace the damaged parts as soon as possible.

Union Fittings: These are located around the pump and the heater, which is another common area to find a leak as the fittings can loosen over time. If the fittings are loose, simply tighten them by hand! Do not tighten the fittings with a wrench.

Valves: There are multiple valve styles on hot tubs, each having its own unique way of being repaired. Some spas have valves installed on one side of the pump so water doesn't have to be shut off or drained when the pump needs repair. Other valves have compartments bolted together with a gasket between the compartmentsthis is known to fail and cause a leak. Be sure to inspect all valves located on your hot tub and replace any as necessary.

Connections: Be sure to check all pipes, jets, and any other connections. Some connections are easy and only need to be tightened or sealed while others may need a full replacement. If you have a failing gasket, be sure you order the right parts as there are different gaskets for different style spas. Have a crack in a PVC pipe? There's a gem called Plast-Aid that seals up cracks or holes, which becomes stronger than the PVC pipe itself!

Shell: Most shells are made of strong fiberglass combined with other layers, so you would think a leak could never happen here. In many cases, it's not the shell that causes problems, but a jet or other component attached to the shell. If the shell does have a leak, Plast-Aid is your friend!
