Just replaced my filter and attached plumbing which fixed a leak on the suction side. Now I am noticed that when I turn on my pump after being off for awhile I get a large amount of air coming out of my returns. I also notice that my SWG cell is drained of water and it takes a couple of minutes for water to flow through it. While I can not see inside my filter tank I believe part of it is draining as well when pump is off. Trying to figure out why this is happening. I see occasional drips coming out of my 3 way valve on the return side. See attached pictures. Advice on how to troubleshoot and fix this issue will be greatly appreciated.
