Anti-freeze in fresh water tank

My manual says to add 5 gallons of non-toxic antifreeze to fresh water tank. I have not seen or heard of this. I thought draining tank would be sufficient for winterization. My current knowledge is to never but anything in fresh water tank other than fresh water or fresh water and chlorine to sanitize/

  • If the only way to install pink stuff is through the tank, then just draining and blowing out the lines might be the best way. Need to take a good look at you entire water system, and how to winterize. How water tank needs to be drained and bypassed.

    I agree.
  • That is one way, but don't do it. Takes forever and lots of flushing to get all that stuff out of your system. Just drain it really well. You water will taste bad and foam forever after.
  • Is there a winterization package with a hose and valves that isolate the FW tank and allows pink stuff to be drawn from gallon containers? If not, putting pink stuff into the FW tank might be the only way to get pink stuff into the water lines.
    What about a Water Heater bypass that keeps the pink stuff out of it?
  • Em, I don't I have a bottom drain and just dump the tank.
