Hi. I have a Pentair backflow valve that might be the culprit, but not sure what to do. Replace it? This week most of Houston lost power during the winter storm and my pool equipment has been shut down for 5 days and pumps drained. My hot tub water level is going down about an inch a day ever since, but it has not reached pool level yet. The water seems to be ending up in the pool as pool remains filled and see water coming steadily out of overflow drain of pool to the street. Cannot turn equipment back on yet as I would also have to refill and have no water due to burst pipe in the attic.
Any advise would be greatly appreciated. Thanks
