Thanks Mark,
This is what I was figuring. Let me ask you two more questions if you don't mind.
1. Should the unloader be piped to go back into the water tank or elsewhere rather than back into the pump. With my experience pumping fire trucks, recirculating water can generate some serious heat.
2. I plan on running the supply hose into the 300 gallon tank at the top with the float valve. Should the line running from the tank to the pressure washer intake be off the outlet at the bottom of the tank or at the top of the tank. I know this should be simple but as usuall, I am thinking to much. My concern of the bottom would be the large of amount of pressure from the water on the pump and my concern with the top is will the pump be able to draw the water out with enough ease.
Thanks, Mike
