I am having the exact same problem in Chula Vista, CA. I noticed it about a month ago and thought maybe it was due to rains, but we have since had no rain and the water level continues to rise. Now I am draining regularly. My pool guy also has no idea what is causing this. We shut off the valve at the house and also have no auto fill and yet the water continues to rise. Our water bill has barely risen. Did the previous two people with this issue ever resolve?
One day an gentleman ran into a magical genie. The genie granted the man only two wishes. The man was drinking a fine stout, and asked the genie if his mug could always be full of this fine beverage and always be cold. And poof it was. He chugged the beer down and it would glug right back up. The man was amazed. The genie was impatient. What else do you want? The man said, of course, another one of these!I wish I had a magical filling pool
Nope. ground water would have to be above the waterline in the pool.Hydrostatic valve in the pool drain , ground water is pushing valve open letting water in,
