Fairly new to pool maintenance and have been educating myself on this site. I am in a SLAM. I am having a problem. Pressure on my filter is raising to the red line today, just four hours after cleaning the cartridges. My pump basket is getting air bubbles. I briefly checked valves and pvc elbows and o ring on the pump basket cover by running a hose over top to see if the basket would fill from a leak spot....read that somewhere on here.... . It was actually an air pocket that spanned the whole window. When I shut the system off, emptied the pump basket, depressurized the filter and then turned the system back on, it was worse. When this happened to a lesser degree yesterday, after cleaning the cartridges, there were no bubbles except for the allowable champagne bubbles for a SWG system.
I can't run the pump 24/7 for my SLAM if I think the pump will run partially dry overnight. Any suggestions?
