Winterizing/de-winterizing water heater

I am finally going to winterize the motorhome today before the deep freeze hits home later this week. MH is 2015 ACE 30.1 and the WH bypass valves are where you must remove a drawer and panel in the bedroom, then stand on your head with a flashlight to find them, pain in butt. I would like to reduce this pain to only having to do it once if my plan will work.
I will switch the valves to bypass WH, drain the WH, pump pink stuff through all the lines. What if I now put the drain plug back in the WH and switch the bypass valves back now instead of doing that in the spring? This way I can put the panel and drawer back and not have to do this again in the spring. To clarify, we always run off the fresh water tank in case that would matter. Thanks, Jim.

  • Why not just leave the drawer and panel out till spring, since you are not using RV. As you have to stand on your head twice, once to bypass and once to return to use. What is the difference if you stand on your head the second time in the sprig?
    That way I will be easier to flush system in spring.

    I thought about this and it would still be easier than messing with the valves twice. Jim.

  • Exactly what I do but only switch the bypass valve back AFTER you have run the pink stuff through all the fixtures, or you will fill the hot water tank up with pink stuff, I have done this trust me takes a lot of pink stuff to fill a water heater
