I need some help here. I have bubbles coming through my return jets, as well as bubbles forming in the pump basket area. I believe its from the main drain side, but i also think there might be an air leak around the filter pipes since when i have it on recirculate, the amount of bubbles into the pool are slightly decreased. its really causing my pH to sky rocket, it was at 8.0 yesterday since i didnt think it had done much, but had indeed raised the pH .5 in less than a week.
just threw a gallon of acid in, per my tests kit, and when i tested it again today it was at 7.3.
is there an easy way to detect air leaks in pvc piping? also, is there a way to repair the air leak w/o replacing the entire piping?
