Is plumbing antifreeze harmful to HW tank?
I got a small amount of antifreeze in my hot water tank when I winterized our 5th wheel. Is it harmful to the tank?

FWIW, all pink RV anti-freeze is not the same. For a number of years now I have been buying the better grade, that contains NO ALCOHOL. I use Prestone RV brand, about 5 bucks a gal. It is easy on your system, and does a good job lubricating your dump valve and toilet seals. It will not evaporate or cause corrosion, like many of the cheaper ethanol based RV anti-freeze.
I use about 3 gals, making sure to get some in tanks, for seal lube. It doesn't cost much more compared to the 3 dollar a gal stuff, plus the added benefit.

I didn't know that Jerry. I'll have a look for that next year.
I checked the RV antifreeze I used and it didn't have any warnings about corrosion.
Thanks
