So, I just recently noticed a new issue with one of my pool returns. Small air bubbles are coming out of it. The sand filter seems to be watertight all the way to the top of the water pressure gauge. I’m not exactly sure what’s going on, or if this is even a problem. Please advise. Thanks in advance!
