Can I adjust the PSI on my pressure washer?
Please note that you can easily adjust the effective pressure of an electric pressure washer (and some gas models) by using a Vario Power Spray (VPS) wand. This regulates the water flow to effectively adjust the pressure washer.

To increase the effective impact pressure of a pressure washer without a VPS wand, simply step closer to the area being cleaned. To reduce the impact pressure, simply step back from the area being cleaned.

Some gas pressure washers have a pressure regulator on the pump. You simply turn the dial to increase or decrease the pressure. Others have a regulator on the spray wand, similar to the Vario wand on our electric power washer. You can also change out the nozzle tips which alter the impact pressure when spraying.
