Just put in a new valve to bypass fresh water holding tank and pull from jug. Stopped by a local RV dealer and so happend a mechanic waited on me, I asked what other options they had other than the diverter valve that attaches to pump. (My pump is difficult to reach so I wanted to splice into suction line and locate valve close to access panel) He suggested the same plastic valve found on hot water heater by pass situations. Just loose and toss the threaded rings that hold plastic water lines, push on the (in my case 1/2 inch ID reinforced nylon tubing) fasten with proper size radiator clamps (worm gear type), pick up some more 1/2 ID tubing that will not collaspe with suction for jug. Yer good to go. Yes the valve is not designed for this tubing but works fine. Cost of valve at camper dealer $14.00 + tax, tubing $0.89 per ft at local hardware store.
