Why is the power supply on my jet pump not working?
The power supply wires were connected to the wrong screws in the pressure switch. The pump is not building to the shut-off pressure of the pressure switch. The pressure switch needs to be adjusted, points are welded closed or is defective.
What to do if your jet pump is not primed?
If everything else checks out okay, then the motor on the jet pump has probably failed. Replace the motor or the entire pump. The jet pump has not been primed. The jet pump is sucking air. The depth-to-water in the well is too deep. The check valve is installed upside down or is stuck in the closed position.
How to troubleshoot a jet pump on a tractor?
Inspect the pump for a jammed impeller or other damage. Clear the blockage if possible so the impeller can rotate freely. Ensure that the wire that runs from the breaker or fuse box to the pump is of a heavy enough gauge. Replace as needed. Make sure the power wires are not touching or grounded where they connect into the motor.
What should the bottom of a jet pump be?
Make sure the bottom of the suction pipe is below the maximum depth that your jet pump is capable of pumping. Make sure the bottom of the suction pipe is below the water level when the pump is turned on and fully engaged. This can cause the water level to drop further when the pump is in operation.
How to troubleshoot a faulty jet pump motor?
1 Inspect the pump for a jammed impeller or other damage. 2 Ensure that the wire that runs from the breaker or fuse box to the pump is of a heavy enough gauge. 3 Make sure the power wires are not touching or grounded where they connect into the motor. 4 Restrict the pump’s output to keep the pump within its designed performance range.
Make sure the bottom of the suction pipe is below the maximum depth that your jet pump is capable of pumping. Make sure the bottom of the suction pipe is below the water level when the pump is turned on and fully engaged. This can cause the water level to drop further when the pump is in operation.
How big should the suction pipe be for a jet pump?
Use 24 inches to be safe. Having an elbow, tee, check valve, or other disruption too close to the inlet of the pump can cause cavitation inside the pump. Is the Suction Pipe Submerged Deep Enough?
Why is the water level dropping on my jet pump?
The pressure switch needs to be adjusted, points are welded closed or is defective. The water level in well is dropping below pickup pipe or below the pump’s lift capability. The water is being used somewhere in the system at a rate equal or greater than what the pump can provide.
