I cleaned the filter grids in my filter, which I've done many times; reassembled them fine; used lube on the lid and large O ring. Everything appeared normal, no leaks that I can see, the pressure just fine, but when I shut the pump off I can hear water gurgling some in the filter and I lose pressure in the tank. I have a Waterway 2 way 2" shut off valve, I disassembled it, cleaned it thoroughly, and lubed it well. Still losing pressure.
Does anyone have an idea what may be causing the problem?
Thanks
Ken
