I've had an ongoing problem with a high pressure reading on my Hayward cartridge filter. I read up on mas95's sticky and eliminated a couple of causes.
High filter PSI, check:
Dirty Filter
Cleaned today
Return valves may be set improperly or partially off
Checked those - they're set right
Check for return side blockage
Oversized pump
worked fine for years
Undersized filter
worked fine for years
Undersized return side pipe
worked fine for years
I guess I need to check for return side blockage. I've used the bladder on it but that didn't do anything. Does anyone have a comprehensive list of how to do this. I didn't pull up anything on this.
