Air getting in from somewhere

[salinda]

Quick question...I have had the champagne bubbles for a while and now my pump strainer basket is almost empty and there is an air bubble in my cartridge filter in the morning. I have been quick to blame the solar system because when I isolate the solar out of the system using ball valves, this doesn't seem to happen. Can solar cause such bubbles too through a malfunctioning vacuum breaker or are the bubbles always caused by a suction-side leak. If so, I only have a Jandy 3-way before the pump and that might have to be serviced.

I have the exact same problem. Mine is a DE EC65 filter though. Pump runs great before night, I leave it on overnight and when I wake up there is no pressure at the returns and the basket at the pump has very little water. I just had all my lines replaced because I moved the filter. I do not see any leaks above ground.

I thought all the air should be forced out through the jets and eventually the entire system would be all water, no air. Last year I had a problem in the beginning of the season with pressue. What I did was remove the pressure gauge and use this wand attachment for a hose that allows you to clean the inside of the filter. I washed the entire inside down allowing any caked up DE to come out the bottom. Seemed to fix the problem. My thought is maybe this is creating a blockage.

Not sure what a multiport valve is, but I do not think I have one. Could the problem be a leaking cover over the basket at the pump? Not sure if there is a gasket there, I think the previous owner of the house just used some sort of sealer in a tube.

Here is a picture of my filter setup.

Actually I don't think mine is the exact same problem....This happens when my pump is OFF overnight. When the pump is on, everything is fine except for the champagne bubbles. I have an autofill unit on my pool, so I don't know if I am actually losing water anywhere.

Hey guys/gals.
It gets very confusing when other questions, even seemingly related, are asked in a thread. Please do not hesitate to start a new thread as that will get full and specific attention.

I appologize, I misread your original post.
