Hello, I have a big job in which we will have to rent a hydraulic lift to clean a 150 ft Church. We will be using 3000PSI Hotsy units @4gpm and I wanted to know if there could be any potential damage to the washers considering that the units will cleaning at such great altitudes. I have heard that the back flow of water pressure can damage the pumps and using a lift is the only possible solution to reach the peak of the Church building. Can anyone help us out? Thanks

No the shouldn't be a problem with back pressure on the pump. how many feet of hose are you going to run you will have a pressure drop with a long run of hose.

Thanks for the response, I will be using approximately 200ft of hose.

200 ft should be no problem at all.
