I’ve just bought a Honda GX390 and Interpump machine and it’s worked a tankful of fuel over the past week. I’m not a contractor but a dairy farmer. The fuel use, for me, doesn’t seem too bad so far and on average it will only be used for about 100 hours a year I estimate. Didn’t consider a diesel one and none were in stock with the dealer who had maybe fifteen of various models assembled and ready to go. This replaces a Dixon’s hot water single phase machine which lasted OK but the hotbox failed and rusted internally years ago. The main advantage of the new machine is increased portability and versatility and more performance than from a single phase electric machine. I really will not miss the hot water and never did after the hot system failed on the Dixon. Also I now suck water from a container/trough, because my water flow and pressure is not adequate to keep up with the machine connected by a pipe to a tap in the dairy. My water comes from the mains but via a 15,000 litre reservoir, so no mains pressure. I like the valve that circulated water back to the container so that the pump does not overheat when not pressure washing. Mine has one of those similar to yours. I don’t particularly like my new split lance where I have to split and attach the foaming gun, but do like the Venturi system that pulls TFR from a 25 litre drum if required. I’ve blown an O ring in the split lance already when the joint came slack after changing the ends between pressure and foaming.
