Leaving antifreeze in my outside faucet.

I'm dewinterizing my '21 International 25 FBT but headed where the nights are still cold. Can I simply close the outdoor shower faucets (opened at winterize) while dewinterizing so antifreeze will stay there? Seems logical but I may be missing something. Thanks!

Leaving antifreeze in my outside faucet.

I would only trust that if you have shut off valves specific to the outside hot and cold fixture water supply, positioned well inside of the trailer, otherwise thereís a risk of some or most of the antifreeze being diluted with water in the supply lines.

Are you planning to pump AF in the lines every night?
Is the furnace on?
If it's below 25* with the furnace off I might worry.

I would turn the pump off open all faucets and low point drains to settle the mind.

Risk of Antifreeze Getting into Drinking Water?

Wouldn't there also be a risk of the antifreeze leaching into the drinking water (assuming there are no isolation valves). If you're just washing, not drinking, maybe it's moot.

I thought winter was over here too but now we are getting some nights dropping below freezing so on Monday I blew the lines out and pumped in some anti-freeze. The most difficult part was getting the slackers at Lowes to find me two of the 210 bottles their inventory system claimed they had. I am taking my International down to Wilmington, NC for a shakedown trip this weekend, I will probably have to repeat the process when I get home. Next week looks like the temps will drop again. Two gallons of anti-freeze and some time spent blowing out the lines is cheap insurance and the outdoor shower seems like the weakest spot to me.

We don't use our outside shower faucet (we may when we get a dog...). I never de-winterized that faucet. So it has had the same antifreeze in that plumbing segment for past 4 years and there hasn't been any problems so far.
