Was looking at my filter last night opened the air release valve on top of the unit (while the pump was running) and to my suprise air was forced out for at least 10-15 seconds before any water was released. Did the same thing today and more air released.
Is this normal? The pump had been running for at least 8hours prior.
In order to pass the final plumbing inspection, my builder just replaced one of the pump's drain plugs with an SVRS device - although I do not know if the air in the filter was present prior to that...
I do notice a few air bubles in the returns and I have less pressure for waterfall/deck jets.
