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
