Thanks for clarification. We currently use an electric hydro jetter for commercial and residential 2 inch lines. I didnt know if gas was different in that you throttled the motor down and then psi goes up by magic or something lol. Ok so greg are you running an 8gpm with the gx 690 and achieving 3200 psi at the pump? 3200 psi is still pretty good. I probably wont be cutting roots much with this unit. I would probably be looking at the root ranger and warthog. Do you cut any roots with the warthog? I’ve heard other guys having good results. At 3200 psi + pressure loss at end of hose i probably will still have root cutting power. It really depends on getting the right nozzle for my machine i guess. Thank you greg for taking the time to answer these questions. This is a lot of money that i am about to spend and experience is the best teacher. (And it sounds like you have the experience)
