A little confused about winterizing

I hate to add to all the post about winterizing, but I'm a little boggled. Everything about winterizing seems pretty simple and straightforward but when I looked at the valve set up for my water heater bypass, it doesn't make sense to me. Are the valves installed in the wrong place or is there something I'm missing?

    Overheard on factory floor.......

    "Hey Ralphie, got a new guy. Where do you want him on the line?"

    "Have him do the plumbing on the water heaters"

    "OK"

    "Alright..here at the valves and tees, tubing is over there. Use blue for bottom and red for top. Got it?"

    "Yeah....just put 3 valves and 2 tees -------RIGHT?"

    " That's it"


    End of day.....

    "So how did it go?"

    "GREAT..no problems at all. Didn't get called out on anything!"

    "OH, we don't inspect here..dealers take care of that"
    "See you tomorrow"
  • its just the opposite of what it should be.

    From all that is wrong with my new one I am guessing Forest river !

    You have a three valve bypass system, and all that is required is to change each valve to the opposite setting to go from normal to winter bypass. This is actually the most robust version, trust me I have the single valve and one of my check valves gave it up this year. You have no check valves in this configuration.


    No that's not correct! It's setup wrong, as has already been pointed out....

    Look again.
  • That's what I assumed. I just thought maybe I was missing something obvious. Thanks for the quick reply. One more item for the warranty repair list I guess.

  • YES......there are WRONG

    The BYPASS valve and line need to be on other side of the Hot (Top) and Cold (Bottom) valves

    The way it is plumbed right now if you close cold & hot and open bypass no water can flow thru bypass and out hot

    Correct way for 3 valve



    In yours......
    The 'Tees' and bypass valve were installed where the valves SHOULD have been installed and valves installed where 'tees' and bypass valve should have been installed

    If handy change it around yourself with new PEX clamps (old ones have to be cut off w/o damaging the PEX) or install using compression fittings or sharkbite connections

    Otherwise....dealer to correct if still in warranty (ones new)


    As is..........you can NOT get antifreeze into hot water side of system unless you fill water heater with it (leave valves open and pump 6-7 gallons)

    OR leave them open (and open bypass to drain that short section) and open all drains----water heater tank and low point drains then blow out with air
