Hi guys, Something really weird is going on.... I'm getting normal pressure, then sudden drop, then back up to normal, then back down and it stays there.
Things I've done:
Cleaned the skimmer line (only have one)
Blew out (with air) the skimmer line from the pump. no problems that I can tell.
Took off the motor at pump and checked for clogs, etc. Nothing...
Motor is about 5 years old and when taking it off the unit and operating in open air, works fine.
