Can’t figure it out

[Brandonlee]

So I have a brand new century pump because my old one started to him after it built pressure it would just start to humm so I connected the new motor and it’s doing the same thing I checked power it’s getting power like it should any suggestions

Important to note that it power my water well

Humming is typically a bad capacitor, low supply voltage, or jammed/clogged impeller.

If you have a brand new pump, then I'd check the supply voltage. Do you have a multi-meter?

 

[Brandonlee]

I checked the voltage I’m getting correct voltage. I checked capacitor it’s reading correctly pumpkins freely motor spins freely and have anew pressure switchI just don’t known

 

[Brandonlee]

Pump freely spins motor freely spins and brand new pressure switch correct voltage I’m at a loss

115v or 230v?
What is the voltage?
Did you measure the voltage AT THE PUMP?
What is the pressure switch connected to...both pressure and electric?

 

[Brandonlee]

Voltage at breaker is 240 and t230 at the pressure switch. 120 on both legs. The switch is hook to the motor. But like I said I checked the capacitor its reading that its good. I bought a brand new motor to try and same thing humming or buzzing withing the motor

OK, so if I understand correctly, you are using a pool pump as a water pump on your well? This is not a pool pump being used for a pool?

In that case, this may help you...

Humming Noise, can it be something other than high pressure?

The pipe humming noise started about 2 months ago. I have a private well with a submersible pump. The pressure switch range is 40-60psi. I noticed the switch actually stops at 62. Then the pressure drops and stabilizes at 60. The humming noise starts at high pressure and continues even when the...
