Why my Graco Xtreme 145cc (600 Water Pump doesn’t operate?
- D
  Deborah CruzAug 16, 2025
  Your Graco Water Pump might not be operating due to several reasons. The valves could be closed or clogged, in which case you should clear the air line and increase the air supply, also check that the valves are open. Another cause might be an obstructed fluid hose or gun, so clear the hose or gun, and consider using a hose with a larger ID. If there's dried fluid on the displacement rod, clean the rod and always stop the pump at the bottom of the stroke, keeping the wet-cup filled with a compatible solvent. Finally, dirty, worn, or damaged air motor parts could be the culprit, so clean or repair the air motor.

Why does my Graco Water Pump have erratic or accelerated speed?
- A
  Anthony WilsonAug 22, 2025
  Erratic or accelerated speed in your Graco Water Pump can stem from a few issues. First, check if the fluid supply is exhausted or the suction line is clogged; if so, refill the supply, prime the pump, and clean the suction tube. High viscosity fluid can also cause this, so reduce the viscosity and adjust the intake spacers. Additionally, inspect for an open or worn piston valve or packings, and clear the piston valve or replace the packings if needed. Finally, an open or worn intake valve could be the cause, so clear or service the intake valve.
