I am having some imbalanced skimmer issues. So I played with vavles these days. I have three vavles in front of pump, one for main drain, two for skimmers.
Once i I close main drain vavle, there will be some consitent air bubbles. Once it is open, no more air bubbles. Why this happens?
another question, I have system 3 filter. I was told by PB that I don' t need to open air bleed vavle on the top to remove the air since there is an air bleed tubing inside. However, every time when I clean the pump basket, I have to open the air bleed vavle to get rid of air. Otherwise they will just stay there. I tried once, it stays there for 2 days, once I open air bleed vavle, it is gone. What this indicates? A blocked air bleed tube?
thanks so much.
happy 4th of July.
