You must have an extremely clean air compressor , drain the water out of it lately.

Yes and yes, it also has a filter.

I don't like buying air tools either.

I use only air for the supply lines and antifreeze for the traps. I don't have anything complicated like dishwasher or ice maker though.

I heard someone suggest using Alcohol (as in Vodka) instead of antifreeze. Not sure how well that would work but you might have volunteers to help you drain it [emoticon].

As you can tell everyone winterizes the way they feel is best for them. I don't care how you use air, air pressure will short circuit water. It will blow out the water ok when the lines are full but once it drops to about 1/2 or less in the lines the air will blow over it. I always drain everything and then run the antifreeze in. It is really cheap insurance for a very expensive rig.

I do use air for my ice maker though. I disconnect the inlet water feed and use pink stuff up to that point. I then push the water out carefully BUT my frig stays plugged in all year and the rv is sheltered. I have a ceramic electric heater in it set at 32 degrees just for an extra margin of safety.

As I said to each his own.

RV Antifreeze for me. It's on sale here for $2.50 a gallon right now. I know my pipes and fixtures will not break over winter and I also know it is designed not to make me sick next year.
For the air compressor guys and gals, do yourself a favor and buy a 3 foot or longer piece of clear rubber tubing. Put it on the end of your airline and blow air through it for a few minutes. Now look at the inside of that tube. If you have an expensive compressor with filters on it you may still have a clear tube. For those like me that have the $100 harbor freight specials with no filters, you will likely see oil and or rusty water left behind. Not what I want to introduce to my water lines.


That is why I use the pink stuff, my old compressor has always had dirty water in the air discharge.

I blow out with air and sometimes I'll suck about a cup of plumber's antifreeze into the lines to protect the pump. It gets dowm to minus 30 here.

I used to use air only until one year my old class C split the line to the toilet. I assume water pooled down from the valve to a connector and froze.

Switched to air followed with AF.

Then I was cleaning my air/oil separator and draining the compressor tank and realized that I wouldn't fill SCUBA tanks with that air and breathe it, so why would I put it in my water lines?

Only AF now for me.

Our trailers has enough low point drain lines that hardly any water comes out with just air. That’s been good for me. The KISS system for me.

Interesting responses. There is a bit of science behind why water doesn't completely freeze even when it gets into the teens at night. Those who use air only are mostly in warmer places that don't get deep freezes for days, or even weeks at a time. Anyone living in the northern states or Canada knows what I'm talking about. In SE WI we had days of -20 over the winter. Not the wind chill, the actual temperature. With day time highs of -10.

The issue I've seen, and have had myself, is getting the water out of all the valves and faucets. Even a small amount of water in a valve can cause cracks. I had this happen in a previous trailer. I failed to open one of water heater bypass valves and allow pink stuff through. The next spring I had a leak.
