  If your Champion Power Equipment Water Pump isn't pumping water, consider the following: * **Air Leaks:** Check the suction hose for air leaks. Ensure it's double clamped at joints, clamps are tight, fittings have thread compound and are secure, and the hose has no damage. * **Blockages:** Inspect the suction and discharge lines for any blockages. Make sure the hoses and filter are in good working order. * **Submersion:** Verify the end of the suction line is fully submerged in the water source. Extend the line or move the pump closer if needed. * **Head Height:** The total head might be too high for the pump. Reduce the total head or consider using a pump designed for higher heads.
