in Heating/Plumbing & Winterizing
I have a 2016 T@B 320CS. I when I winterized it yesterday I forgot to close the necessary valves and open the alde bypass valve, thus allowing RV Antifreeze to enter the alde heater. I know I cannot run the heater until it's flushed clean of the Antifreeze.  Two questions: what's the process for flushing RV Antifreeze out of the alde; and can my T@B be winterized if it went into the alde? Thanks for any advice.

    The issue with RV antifreeze in the Alde tank is: if you camp in the winter, and use the heat, some mixtures of RV antifreeze "might" boil, and "maybe" cause damage to the tank.  So, just having RV antifreeze in the tank isn't an immediate cause for alarm.  Here is a thread that discusses this: https://tab-rv.vanillacommunity.com/discussion/14336/unapproved-winterizing-the-alde-3020-in-a-2021-tab-320s

    If you don’t plan on using the Alde until spring, the antifreeze in the Alde will not do any harm.  The issue with antifreeze in the Alde concerns using the boiler and heating antifreeze beyond its peak temperature.

    Just for consideration...

    Many years ago, in a different camper with a conventional 6-gallon hot water tank, I somehow accidently ran anti-freeze into the tank & it sat over the winter.  
    Because there was (apparently) a buildup or layer of calcium scale in the tank, the antifreeze absorbed into that layer.  It took several years of use to get the odor down to a level where it was unnoticeable.

    Hopefully this tank design and/or your water quality eliminates that experience!
