Unloader Valves & Repair Kits

When using a hot or cold pressure washer the user will need to release the trigger at some point. The problem here is that the pump keeps building pressure, so the use of an unloader valve or bypass valve will take the unwanted water away to the low-pressure side of the pump.The unloader or bypass valve will dump the water to the inlet part of the pump or header tank. 

Some unloader valves have a pressure switch so when activated the pressure washer will time out or stop when the trigger is released.

The pressure can be adjusted on the unloader. New seals or a new unloader valve can be purchased here. This part has a great effect on the working pressure.
