Hi,
Having an issue on the pressure side with air getting into the system when the pump gets turned off and I cannot seem to locate the leak. Started noticing about 8 months ago with a little air being forced through returns whenever the pump would turn on. Gradually got worse so I decided to try to change out multiport gasket and o-ring when I cleaned DE filter this fall. After performing that work, the leak got worse to the point where I would lose prime in the pump basket. It always started on the pressure side where I could hear air seeming to enter the multi-port, then eventually the pump would lose prime. When on, the system works just fine - no visible leaks anywhere, and no air entering pump basket. pool doesn't appear to be losing any water.
Called in a pool repair company that I had used when I first moved in to help me open. He insisted it had to be on suction side, couldn't find anything and recommended check valve after my pump. Put in the check valve and would still lose prime after turning off. Started playing with the multi-port handle after I turned the pump off, and I can hear the leak stop when the handle is pressed down just the right amount. Changed the multiport gasket and o-ring again, with same result.
I'm at a loss for where to look and how to fix. The multi-port gasket handle has been "loose" when locked into position since i've changed the gasket. I don't remember it being super tight previously, but it does now appear to have more play into it. I read a link earlier that multiport gaskets may be a little thicker now, causing the handle play that i'm seeing, but not sure if it would cause the air leak
Pool/Equipment:
~13K gallon gunnite
1 HP Pentair Challenger pump
Quad DE 60 filter
2" hiflo multiport (261050)
Mastertemp 250
IC40 salt cell
Booster pump
