    How do I winterize 303rls?

    I am not sure where the winterization fill is on the reflection.
    Thanks,
    Peggy

    The way I understand it, you set the can't leak valve to the winterization positions shown on the door and use the pump to pull the antifreeze through the city water connection.

    I believe Nick is right. As the pump is pulling antifreeze have someone open each water faucet until antifreeze appears. Don't forget the outdoor shower valve. And before you do the antifreeze thing drain the hot water tank. It is behind an outside cover.. Unscrew the plastic 3/4 inch nut, and lift the pressure valve lever to release all the water. Next spring make sure you fill the hot water tank before firing up the heater.

    Also make sure you winterize the black flush tank line, it has a backflow preventer valve in it and mine froze last year. I blew it out with a compressor but evidently there was still water in it. Just a word of caution as I learned the hard way. Now I pump antifreeze in it with a hand pump until i see it come out of the black tank.

    All good, don't forget the low point drains at some time. I always trip the water heater circuit breaker before draining the heater and don't reset it until after I have refilled the heater in the spring.

    Did ours today. Put valves in winterize, bypass mode, drained the water heater. Took caps of low point drains and opened inside taps to let water out, (those caps are a bit of a pain, would be nice if GD would install taps instead) closed taps and put caps back on. Ran hose from antifreeze jug to city water connection and pumped antifreeze through the system. Quite easy.

    Ditto. Did exactly this myself on Sunday. Just read the above warning on the black flush which I may have to go back to storage and hand pump some anti-freeze into.

    What are you using to hand pump antifreeze into the back flush.

    I bought a hand pump anti freeze kit at Camping World, that is what I used.

    I noticed there are no shut off {by pass} valves at the hot water tank. Did the antifreeze get to the cold and hot water lines going into and out of the hot water tank without filling the tank with antifreeze?
