Normal pressure has run 12-14 psi. Replaced a 3/4 hp motor with a full rated 1 hp and a SF of 1.5. Pressure runs at 20 psi. Changed sand in Hayward 220T filter, still 20 psi. 0 psi on backwash or waste but still 20 psi on recirculate? Is the pump too big now? If so what impeller do I need to downsize it. Original Hayward 2607x10 . Thank you for your advice
