So after pulling apart my filter and cleaning it yesterday, it worked great for about 3 hours and then psi jumped to 30 from initial 20 again. What concerns me is that when it goes up like that I start noticing little air pockets in pump basket. They were not there before nor do they appear when I have it on just recirculate. I've been reading the stickies on if leaks. Am I going crazy or do I have a leak problem somewhere ? But why forest it take a few hours to show up?
