Great forum guys... My problem: I've installed a new 1 HP WaterAce 230v convertible pump, set it up as a shallow well jet pump. Static level is 10' footvalve is at 32', I replaced the existing suction pipe and footvalve with a 1 1/4" , (it used to be 1"), replaced the pipes on the pressure side with 1", (used to be 3/4) and I can't get the pump to get above 30 psi, so therefore the pump never shuts off, and it heats up, possibly due to cavitation? I'm not sure what is going on and any help would be appreciated. Prior to my old pump and motor going out, (also a 1HP) I had the pressure switch set to 40/60 and no problems at all.
