Karcher pressure washer

I bought a brand new (returned) unit from Lowes for $250. It was a 2500 psi with 5.5 Honda, and it came with a new warranty. I figured I couldn't go too wrong because the engine was worth that. I took it home and found the pump had a broken piston and called about the warranty. They rebuilt it and I had the unit back in my hands approx. 2 months later. It worked great for about 2 hours and broke another piston. Water hose kinked on me and the pump started hammering before I could unkink the hose it was history. I took the pump apart and noticed it uses water pressure to keep the pistons pushed against the Axial Cam, if you get air or starve it for water, the piston starts floating - Like floating the valves on an engine due to being over-reved.

Here was the solution, I bought a brand new General Pump for $150 on the internet, bolted it up, and have not ever had a minutes worth of trouble. So, for $400 I now have a $900 pressure washer 2500# @ 3.0gpm
