Coachmen leprochaun water heater bypass

No that's how mine works. I shut off the valve at the fresh water tank under the bed, put a short siphon hose from the hose connection into the jug of antifreeze and turn on the pump. If it siphons from your fresh water tank it should siphon from outside jug as long as that valve at tank is in bypass.

You have it done now but that is how it should work. Sorry couldn't of been of more assistance
