re: Pressure Washer specs

I do get a lot of them in my repair centers that come from Lowes and Regional home centers.
99.9% the pump gets a build up of calcium from sitting and when the person cranks it they force it instead of using a pump flush and damage the pump. They also run the engine without the water hooked to the pump.
Is it the best pressure washer? No, it is a residential unit.
For the guy using it here to clean a house, sit it up a few months use it to clean a boat, and then maybe even wash a car once in a blue moon they are ok.
Again use pump flush when you store it and drain the fuel tank if you sit it up.
