I recently changed my filter cartridges out and immediately noticed lower pressure at the filter. The pressures used to read about 10psi when “clean” and creep up from there. I was overdue to replace these so thought maybe the 5psi reading after competing the job would be my new “clean” psi.
I quickly noticed that my spillways from the spa were not flowing like usual so I believe there is a flow problem. Pressure has also been between 0 and 5 ever since the change. At first I thought I had clogs in my drains or skimmers, but they are clear and the after flow is pretty good.
Strangely, when I manually switch my returns to spa only, pressure builds to about 10psi in the filter and the pump sounds like it is operating normally.
That made me think maybe I have a clog in my returns. But, if I keep the pool returns on and switch my intake to spa only, the pressure builds in the filter and the pump stops straining as well.
Any ideas?
