For some unknown reason, my newly acquired pool (Blue Haven approx. 5 yrs. old), has a filter that doesn't always prime. I have to hit the service light button to stop the filter, unscrew the filter pump basket lid, add water (repeat up to 3 times) then it will fire up.
The previous owner said that he rarely encountered this problem. Recently, the motor was replaced (supposedly with a new ring), I had the sucker/skimmer check valves replaced with new o-rings due to frequent clogging and contributing to the priming issue. I had two pool service techs (from different companies) come out and do a check/maintenance. One suggested disabling/plugging the 02 Oxidizer to increase filter flow (decrease air in plumbing). I just disabled it so I'll see the effect it will have shortly. Flow is certainly better without the oxidizer.
Any ideas? Air being scavenged somewhere not yet noticed?
Oh yeah, the pool tech/owner said the Oxidizer is overrated and ineffective. I'm going to research that one...
