Winterizing toilet??

Whichever RV antifreeze you choose, just drain it all out after you put it through your system.
Why would you need to leave it in the water lines , pump and fixtures once you have put it through to protect them ? At that point, the antifreeze has diluted any residual water left in the system , just get rid of it once it has done its job and you won't have to worry about any taste come spring.


If you choose to do it this way, then lubricate the seal separately .

That is an interesting thought flushing it out immediately. However Glycol Antifreeze does not dilute (strictly speaking) it displaces water, they do not mix. I don't know if it is a me thing, a north thing or a Canadian thing, but when we regularly get double digit negatives, sometimes for a week or more at a stretch, it is nice to know that the antifreeze will displace any left over water that may be lurking somewhere that blowing out or flushing out did not catch. We usually do not have access to a dump again until our first spring trip anyway so no rush to get rid of it.

If you use the cheap ethanol based anti-freeze, it may dry out seals, and will evaporate. It only takes a few gallons to winterize, so I don't mind paying 5 bucks a gal, for higher quality. It won't evaporate, won't stain, and is actually a good lubricant for seals.

The higher quality (Glycol) is mineral oil based which is why it is good for the rubber seals. Downside is it is not as easy to find and costs 4 times as much. The other good side effect of Glycol is that it actually tastes quite good and does not leave that Antifreeze taste in you fresh water lines...

I run pink thru the toilet system and leave some in the bowl. I also pour a little olive oil and flush it to help the seal.

I've been using pink stuff in the toilet bowl for years. No staining and no other problems.
