I have no hesitation in using my compressor for blowing water out of the lines during winterizing. Sheesh, the quality of air coming out of my compressor is probably better than the air breathed in most major north american cities.

Compressed air is also compressed toxins in the air plus compressor debri. Your shop compressor can multiply the crap in your air to 'dangerous levels'.
Check out 'food grade compressor'.
I use a minimum of air by opening all faucets, draining most water with drains- low point, fresh tank, and water heater. I tip the trailer up for a while and then down until I see no more coming out. Then a quick shot of air through almost dry pipes and I am done.
Fast and simple,.. Anti freeze in traps only.
Fill the tank in spring and run a few gallons through the lines, taste it, and ready for another season!!

I wonder if my compressor is "food grade?" Just drained and then blew out my lines. Even unscrewed the cap in the sink trap. No antifreeze for me.

Don't forget the bathroom trap.

That's what they say. My Craftsman two cylinder compressor is 43 years old and I drain it every......ah,......well, when spray paint I do drain it.
One thing that surprised me is that the oil level in the sump never changes. I've changed the oil maybe twice in all that time and the compressors seen a lot of use, everything from spraying gelcoat, painting and lots of air tools in my shop but the oil level stays the same. So that tells me there can't be very much oil going out with the air. I still use downstream filters etc. but I'm not worried about using it for blowing out my waterlines.

I know we aren't discussing the breathing aspect of compressed air, just the use of compressed air for water removal but the below article is interesting.

For those that are interested you can buy a fairly inexpensive valve to install in the drain for your tank (replaces the stock drain valve) that opens when the pressure is below 5 lbs and automatically drains the tank every time.

Good point but it must be remembered that the air in your compressor is most likely coming from the air surrounding where ever your compressor is.

Not sure what point you are trying to make Mel. Hopefullyy, you will elaborate. Maybe I am missing something.
I do not agree with your choice of the word "multiply." Compressing air is not going to multiply the amount of contaminant in the air. It will compress them into a smaller area. But air that is compressed is the same air that is being inhaled in the garage or shop where the compressor is in operation. And when that air comes out of the compressor it expands to its original volume, reducing the concentration of air borne contaminants to the same concentration it was before it was compressed. I fail to see how this can be "dangerous levels" as I am not inside the tank breathing concentrated levels, and if I stay in the garage or shop long enough I am going to inhale more contaminants than can be compressed into a 5 or 10 gallon tank anyway.
If I lived where winterizing were necessary, I would use compressed air and restrict antifreeze only to the drainage system (traps and gray/black tanks if used during periods of freezing weather.

I'm not worried about the air itself as much as I worry about the stuff that is being carried out of the compressor, such as the oil and smelly rusty water, not to mention the accumulated stuff in the hose. Propylene glycol has very little taste and odour, so, if the system is flushed properly, I doubt that any taste would be detected.

Except that some RV antifreezes contain alcohol and corrosion inhibitors. Read the label. They all say "not for human consumption." With instruction to contact a physician or poison control center if accidentally ingested. Screw up and what are you consuming? And as has been stated in this thread, if properly maintained, the compressor "problems" mentioned will not exist. But as I have stated in other threads, each to their own. Got to do what makes you comfortable. I want nothing in my potable water lines but filtered air and water, and the quality of water is sometimes questionable. And I will go on record to say that the filters commonly used on RV hoses may inactivate and filter out chlorine, but they do not stop toxins and other contaminants.

Isn't plastic ( like hoses ) made from oil?

Everything one touches has been touched by a possibly questionable substance. When can we stop worrying?
I think the point of the label warning is "don't chug from the bottle". Dish washer soap shouldn't be consumed from the container either. I think properly rinsed dishes as well as RV tanks are rather safe. That said, I don't drink from the fresh tank.

J Mac.....
I agree with you. You said it better than me. The point I tried to make is that all the people worrying about using an air compressor fail to understand RV antifreeze also has its downside. If either us used properly, there should be nothing to worry about. Just follow accepted practices for each method.

Sure glad I use neither compressed air, nor RV antifreeze to winterize my water lines. I will definitely be living longer than the rest of you, it would seem.
