My spillover spa is draining to just above the returns each night when the pump is off. Here is a pic of the return side:
There is the main neverlube valve, then 2 check valves. Not sure why there are 2? Can anyone explain my setup. I am a new pool owner but am very handy. Can anyone explain how to check these for leaks. How do you check these without water pouring all over the place?
The valve actuator on this side is not working, I will replace that this weekend. Could that be the problem? Or do you think it is the check valves? If so, which one?
Thanks for the help!
