Spa Draining to Pool -- How to stop it!!
#1


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!!
