Very high pressure in the hose line when the gun shuts offUpdated 6 days ago

 

Problem 

Probable Cause 

Solution 

Very high pressure in the hose line when the gun shuts off 

Excessive tightening of the spring in the unloader valve 

Turn the unloader valve counter- clockwise to reduce the pressure setting in the spring. If that also does not help, check if spring is stuck. If it is stuck, replace the unloader valve. 

Pistons not moving smoothly/ getting stuck 

Check & replace if necessary 

 

Note: Unloader valve is considered consumable and typically has a shorter life span than the pump. 

Please reach out to us [email protected] after this troubleshoot with your order number and findings. A short video/photos of the system would be very helpful.
