The Water Pressure Very weak again!
I used it a half dozen times this summer and its back to very weak power! The engine seems to run steady and alternates to higher revs. when spraying however I maxed out unload-er adjustment on my pump, and not getting the high end feel at 3000 psi should be putting out!! Seems equal to a hose pressure.
I can put my hand if front of the water just inches even on high pressure
I already took the un-loader out and cleaned what I could very slow ( spring looks goo and intact) and little movement on the funnel type nose, not sure what else to look for?
I guess i need to break down the pump and find the problem?
Could there be corrosion in the pump itself. I think the pump was not used for a couple of years before i bought it.
Any information or other suggestions?
