I have a pentagram variable pump and 4 c4000 cartridge Hayward filter.
Today I cleaned the cartridges like I always do, put the lid back on, primed the pump with water.
As always, it looked like everything was fine until the pump kicked down in RPM. A rush of air came in. I tried holding the RPM high for a few minutes and it looked great but once the RPM kicked down, air came rushing in.
I decided to pull it apart again (filter and pump top) put it back together and I get the same result.
I let it run for 30min and I still does the same thing.
The pump is working but I know something is wrong. When I shut it off I can hear the air and when the pump goes to the lower RPM setting air rushes in.
I’ve done this plenty of times before and have not encountered this. It was working fine yesterday.
Any ideas?
