There is an ideal spring tension for each unloader valve on a given pressure washer that will result in maximum pressure when the pressure washer trigger gun is engaged, and minimum spike in pressure when the trigger gun is released.here is an ideal spring tension for each unloader valve on a given pressure washer that will result in maximum pressure when the pressure washer trigger gun is engaged, and minimum spike in pressure when the trigger gun is released.
3,000 to 3,500 PSI power wash systems are the standard equipment in the contract power washing industry. A big reason for this is that while there is not much of a price difference between 2,000 PSI and 3,000 PSI washers, there is a tremendous difference in cleaning power.hemicals. Water Pressure-PSI. Water pressure from the pressure washer is measured in pounds per square inch or PSI. This pressure is the amount of force delivered to the surface being cleaned, and is the critical factor in breaking debris from the surface being cleaned.
