What to do if my MasterCraft Water Pump motor runs but doesn't pump?

If the motor of your MasterCraft Water Pump runs but the pump doesn't pump, consider the following: * **Inlet clogged:** Inspect the inlet and clean it if necessary. * **Discharge line plugged:** Clear the discharge line and check the valve for any obstructions. * **Low line voltage:** Refer to the corrective action for low line voltage. * **Pump airlocked:** Drill a 1/8" (3.2mm) hole in the discharge pipe just above the pump body but below the check valve. * **Broken impeller or shaft:** Replace the impeller or shaft as needed.
