Low nozzle pressure is a common complaint generally caused by one of the following:
1. Plugged nozzle tip.
2. Inlet screen plugged.
3. Insufficient flow in gallons per minute (not pressure) to the pump.
4. Unloader valve stuck open due to debris lodged under the check valve ball.
5. Customer use of shutoff-type quick connectors.
6. Plugged hose.
man, I was already to tear this pump apart and all it was in reality was the inlet screen! Thanks
95% of the water comes out from under the presure washer through a valve very little comes out from sprayer as soon as i turn it on water sprays out from underneath
that explains it. Sometimes my PW works, other times, it gallops and I never build pressure. This past time, my wife informed me that both the DW and Clothes washer were running. Though the garden hose appeared to be spurting fine, I don't think the volume was sufficient.
My pressure washer used to have good pressure at first, and then, as it ran it slowed down. Now it has no pressure and is no better than the hose. I'm not sure where the unloader valve is that is suggested that it might be stuck open due to debris lodged under the check valve ball.
