My returns have a little bit of air coming out of them, and my pump has some air in it.
1. My water level is high enough going into the skimmer.
2. Suction valve is open for both the main drain and skimmer going into pump.
3. I believe the o-ring for the pump is making a good seal on the pump cover.
Also, I have a valve after my filter going to my returns. One of the lines has always been off since I've lived in the house, and I still have water coming out of the 3 returns. I don't have a good idea as to where the other line goes. Any ideas?
I don't know if this is contributing to my algae issue.
