pentair pump, cant tell what hp, too faded.
Got rid of in line chlorinator so it was 2 less holes to worry about sealing up and I never used it. Just replaced with a straight line of 2" pipe. Now my pressure is running higher, was around 10-12, now its pushing 15 psi and im getting a little bit of air in the filter pot. Only happens when the pressure rises. Is my pump not strong enough to pull/push with the extra pressure? Its not leaking anywhere, pad is dry and its holding suction if I turn the pump off.
