What to do if Graco SaniForce Water Pump will not prime properly or only pumps air?
- MMichele DelacruzJul 27, 2025
If your Graco Water Pump won't prime or only pumps air, here's what you can check: * Ensure the air valve is open and the air line isn't clogged; if it is, open and clear it. * Increase the air pressure if it's not sufficient. * If the hand valve is closed or clogged, open and clear it. If the hand valve is dirty, worn, or damaged, clean or service it. * A worn or damaged piston may also be the cause. In this case, replace it.
