I heard my pool gurgling this morning when the filter was supposed to be running. A lot of air was being injected in the water thru the jets. I checked the equipment and the pump wasn't priming. Water was flowing, but it never filled the basket and primed.
I was just out there looking things over again. Checked the impeller and o-rings. No problems there. I cranked it up and happened to notice the top of the filter (stainless steel) actually bow up and the pressure jumped up to 50-60psi in a few seconds (normally around 15psi). I took the filter top off and removed the DE panel assembly. Turned pump on and the basket filled in a few seconds. The filter is staying under high pressure even with no pump running.
I guess this all means I have something clogging my pressure side. Right? What now?
