RV Anti-freeze question.

The only reason I can see is you just might forget you didn't clear the lines if the occasion comes up for a trip soon. I forget a lot of stuff now.

Just doesn’t take that long to rinse out or cost that much to reinstall IMO. I want to be ready to go when it’s safe too!

From a person that doesn't use anti=freeze in fresh water lines, flush it out and sanitize the system.

First - read the label of the product you used. If there are limits, it should tell you.

Second - if you are like me and most of us who threw away the jugs. Just remember to flush and sanitize before you use the RV. Write a bit sign and tape it over the sink so you don't forget.

The value of RV anti-freeze is not that it avoids freezing. It will freeze if the temps get cold enough. But it will NOT EXPAND as it freezes like water, thus will not damage the lines, valves and fixtures.

Personally, at the relatively cheap price compared to replacing broken valves and such - I'd flush it out and add new next winter.

I will go with that. And after you flush and clear the system.. You will most likely go back to blowing out the lines.

Oh I know about all the WARNING types who yammer about the few harmless drops of water that remain in well blown out lines (I like to blow 'em out at least 10 times pausing between blows) Ignore them.

But Just remember this: If the AIR freezes.. You won't be worried about the RV.

Please, please I'm not asking about anti-freeze vs. blowing out lines. I'm not asking about what if I get so feeble minded that I forget to flush the system and I drink a gallon of the pink stuff before I realize what happened. None of the above!

All I'm simply asking is if the RV anti-freeze will cause any issues by leaving it in the line for a year.

The anti-freeze could soak into the lines, aluminum water heater tank and any other porous portions of fresh water system.

so with all this help,, I use the pink stuff, flush clean. use your own good sense .do what makes you feel good about the job. p.s. I think one winter is enough.

I drain the pink stuff out of my lines immediately after winterizing so nothing is left in the lines and it makes flushing much faster in the spring.

I say drain it and don't worry about it in case you can't get out this year. It still won't freeze next winter and it isn't in your lines all year.

I would drain and flush simply because leaving it in year round isn't what it was formulated for or how it was intended to be used.
