Hot Tub Parts


This is the first thing which you will need to check while inside the equipment’s compartment. One of the leading causes of leakage is the seal of the pump. To solve this problem, you will need to replace it with a new seal. In most cases, you can be saved of a lot of trouble when you get the entire wet end replaced.


You will need to look at the union fittings in the heater and the pump. Even unions for brand new spas may become loose at times because of vibrations when being shipped.


You need to check the pressure switch, heater assembly and other elements of the heating unit and check if there is any leakage. If it's there, make sure you replace it.


The valves are a common source of leaks and you should check them. No matter the type of a valve, make sure you check it.

Connections and Jets

If after checking all the above you don’t find any leaks, proceed on and check all the pipes, connections and jets. Make sure they are tightened and resealed with good glue such as PVC glue.
