Spa Draining Addendum A Leaking 3 Port Vavle

This is meant as an addendum to the previous article "Why does my Spa Drain" that can be found here

Although unlikely it is possible for water to flow through a closed three-way valve with or without an actuator attached. This happens when the raised rubber seal breaks or becomes deformed, allowing water to flow past a closed seal. On a perfectly working system, when the system is turned off there should be no sounds coming from the pipes.

I have only seen this happen twice and each time was with a Waterway TruSeal 3 port valve.

Below is a picture of a valves insides that allowed water to pass through even when closed.

The rubber seal around the edge has torn.

The fix is to replace the insides of the valve. Once the screws holding the top are removed, the top plate can be pulled up and off.

A new TruSeal valve is shown below

  1. We moved into a new home and the previous tenants left a hot tub. It worked well for the first few weeks. We came to find out that they didn't keep very good care of it and it finally just shut off. We have been trying to repair it ourselves but we can't figure out what is wrong. What is the best way to find out how to fix it?
