Few months ago I noticed that our pool would somehow accumulate excess water and I had to backwash in order to bring our water level down to normal. I thought our pool's water leveler broke so I replaced it. Well, it did not help. Then I noticed that sometimes, after a spillway runs for 10 minutes (it is on auto, runs for 10 min every day) the water from the spa would continue to trickle into the pool. One day it was fine, another day it would trickle. Well, right now it trickles non-stop.
We have a separate pump for a spillway/fountains and I just saw that the water was slowly swirling inside of it even though the spillway/fountains were off. Also, it continued swirling even after I turned off our pool pump.
What might be the problem? Thank you!
