  If your Master Water Pump won’t start or run, begin by ensuring the pump is properly plugged into a functioning outlet. If the fuse is blown, replace it with a fuse of the correct size. If the line voltage is lower than the recommended minimum, inspect the wiring size from the main switch on your property. If the wiring is adequate, contact your power company or hydro authority. If the motor is defective, replace the pump. For a defective float switch, replace it. If the impeller won’t turn, take off the lower pump body to find what is causing it to bind. If the float is obstructed, remove the obstruction.

  If your Master Water Pump won’t shut off, the float switch may be defective and needs replacing. There might also be a restriction in the discharge due to an obstacle or ice in the piping; in this case, remove the pump and clean both the pump and the piping. Another potential issue is an obstructed float, which requires removing the obstruction. Lastly, a restricted intake screen can cause this problem, so remove the pump and clean both the intake screen and the impeller.

  If your Master Water Pump operates but delivers little or no water, several factors could be at play. Begin by verifying that the line voltage meets the recommended minimum; if it falls short, inspect the wiring size from your property's main switch. If the wiring is adequate, reach out to your power company or hydro authority for assistance. Also, inspect the impeller for obstructions and clear them out. For impellers that are worn, defective, or plugged, attempt to clean a plugged impeller; if wear or defects are present, consider replacing the pump. If you have a check valve installed without a vent hole, create a 1/16” - 1/8” (1.6mm-3.2mm) diameter hole between the pump discharge and check valve, positioning it 1-2” above where the discharge pipe connects to the pump discharge and belo...
