I have not been able to get my pump to hold a prime for more than a few hours, and it is difficult to get a prime in the first place. I have tried shutting off the main drain line as well as the skimmers, but it still will not hold a prime. I have primed my filter and can get all the air out of it, but when the pump loses prime I can see air in the filter spy glass. It was working for several hours the other day but the pressure increased on the filter due to the first vacuum, so I did a backwash, and it has never been even close to holding one since that. I see lots of tiny air bubbles in my return lines. I have checked the screw in the bottom of the pump and it is tight.
I have a couple of returns that do not have the eyeball fittings on them yet. There is plaster build up on them and they will not screw in. Also several other of the eyeball are not screwed in flush with the wall. Could this be causing air to get into the system? I can give more info, but wanted to ask about the eyeballs first, because if this is an obvious cause then I should take care of it first. I have tried chiseling the plaster off a screwdriver, but it is hard to get it out from between the threads of the fittings. We were told they didn't need to screw all the way in, but don't know if that is correct. Thanks for any advice.
