I recently purchased a VS motor from Inyopools for my 1.65 pac fab challenger pool pump. I got the motor replaced with all the kit, no problem. My problem however is that my pump primes, but the pressure wont come up over about 7psi. Could I have a bad impeller? What do I do to diagnose issue? I checked the gauge and the pressure is in fact low (i can hold back the flow with my finger, easily).
Hello Christopher - It could be a clogged or damaged impeller. You would have to open up the pump and visually inspect that. For more troubleshooting tips, check out our article titled “How Do I Correct Low Water Pressure”.
