Searched the forums and cant find any posts on this. When I wash flat surfaces I am at 8gpm and 3500 psi with cold water when using 100 ft. of 3/8" ID 4000psi typical high pressure hose. I want to go to 100 ft. of 1/2" ID hose to reduce pressure/flow loss. 1/2" ID 4000 psi sewer jetting hose is cheaper and lighter than the corresponding typical high pressure hose…. Any recommendations?
