We have an inground pool with attached inground spa. The spa sits higher than the pool. For 13 months, no problems. Then after 3 days of rain and no one touching the controls, the level of the spa keeps draining to the pool level. This happens whether the pump is on or off. We have 2 auto jandy valves, 1 manual jandy valve, and a check valve. Why is the spa draining to the pool? What should I do to stop it?

Anything helps!

Thanks!!

 

Might look at the Jandy valves are they set right? Could be they need new O rings in them they are letting air get in to them and that lets the spa drain.
