Now that the hot water tank is drained, I re-place the plug, flip the by-pass valve on the hot water tank and now turn the by-pass valve on at the pump. Now I place the suction line on the pump, place it in a jug of anti-freeze and turn on the pump to prime the pump with it. Now I go to the farthest tap which is my bathroom and start 1 tap to get anti-freeze through it. Once you see the pink color, stop. Go to the next tap and repeat. Then do the bath tub and shower. Once you see the anti-freeze come out, stop as the line is full now. When the jug run’s out, just replace with a full one. Now do the taps in the sinks as well. Also don’t forget to do your toilet to! On my camper the lines are clear so I see that all the lines are full of anti-freeze underneath my sink.rv washington
