What to do if my GORMAN-RUPP PUMPS Water Pump stops delivering rated flow or pressure?
- BBradley PetersonAug 9, 2025
If your GORMAN-RUPP PUMPS Water Pump stops or fails to deliver the expected flow or pressure, it could be due to several reasons. An air leak in the suction line might be the cause, so you should correct any leaks. Other possible solutions include replacing the suction hose, checking the pump vacuum, replacing any leaking or worn seals or gaskets, and cleaning the strainer. Also, ensure the installation has proper submergence, replace any worn or damaged parts, check that the impeller is centered and rotates freely, and remove any debris from the impeller. Consider installing a bypass line, measuring lift with a vacuum gauge, and reducing lift or friction losses in the suction line. Finally, check the engine output.
