Why is my Parker Pressure Washer pump not reaching the required pressure?
- JJustin TurnerAug 2, 2025
There are several reasons why your Parker Pressure Washer pump might not be reaching the required pressure. It could be due to the pump sucking in air from loose connections or a damaged hose; in this case, check the tightness of all connections. Alternatively, the suction or delivery valves could be clogged, requiring you to clear or replace them. It's also possible that the unload valves are stuck; try loosening and re-tightening the regulating screw. Lastly, a worn-out lance or nozzle can cause this issue, so inspect and replace if necessary.
