Leaving potable antifreeze in the system

I haven't used my TC since last fall so now it's been a year since I filled the water system with potable antifreeze. And I have no plans to use the TC until next spring at the earliest....when a Covid-19 vaccine is available.

Do I need to change it since it's a year old?

    Thanks for all the input.

    Now, I'm concerned about the fresh water tank growing mold. I think a half cup of bleach might be a good idea.

    Thoughts on that?

    Good idea about the traps and toilet. I just winterized although I’m going to use mine, so it will be an off/on kind of deal for me.

    I have a similar situation with a TT . I'm going to leave it but I'm going to refill the sink and shower trap because I'm not sure if it evaporates . I will leave some in an open bowl this winter to test .

    I would change it just because it probably doesn’t even take a 1/2 gallon.

    i agree with time2roll - it does not cost that much for the peace of mind.
    will take only a few minutes to flush out the old and put in new anti-freeze.
