Anybody have any ideas about this situation:
First my setup:
I have a Jandy 1.5HP PlusHP pump which goes into a Jandy CV 460 FIlter, then a Jandy AETI 2000 Heat Pump, Then the aquapure.
Next it goes to my Paramount 6 port in floor cleaning system.
I have one skimmer return and one floor drain [and the mdx safety drain mounted on the side wall].
In this scenario the pump primes fine but takes a while to fill up the last little bit of the pump lid and get rid of all of the air.
There still remains either some small air bubbles or a large air bubble...maybe 3 to 4 inches long. No air is coming out of my returns.
My pump NEVER loses prime...I'm just a little compulsive on why there is any air in my system. I have a new oring on the lid and have leslies pool lube on the oring and a bit on the pump.
IF I flip a switch and activate my 2 shear descent water falls, thereby bypassing the infloor cleaning system, within minutes the bubbles in the pump go away and I am left with a perfectly clear view of my pump filter basket.
If I then change back to the infloor system, shutting off the waterfall...the bubbles eventually come back...but only after a while.
When I am operating the infloor system, the pressure gauge on my cartridge filter reads around 20psi. When I am operating the water fall, it reads around 14PSI.
The return path for the water is identical in both scenarios. 50/50 skimmer and main drain.
