Presure washer Doesn't stay on full pressure pulsate


Answers :

Adjust the screw on the pressure regulator on the high pressure hose is one way The other is to check the nozzle for obstructions. The problem is that there is insufficient flow from the nozzle so the regulator valve is trying to cycle between cut off and working pressure.. The regulator is set at factory for a particular size nozzle and anything that alters that ratio will cause you problem. The screw on the regulator has some fine adjustment to allow for slight changes. Any impurities in the water supply will tend to block the nozzle affecting the regulator .
