I'm thinking about getting an air compressor (or putting it on my Christmas list). If I do, I would want to use it to winterize my RV. Do I need to get an oil-less one for that?

Thanks in advance,

Would think you would not want any oil residue in the lines. Also you very much need to keep the pressure low(20psi or less) in the water lines of the RV. It does not take much to blow the lines and it takes less to get the water out.

Have seen the air pump used for a mattress modified for use in blowing the water system. High volume, low pressure.

Keep the stand alone air compressor for other uses and why not use the RV antifreez in the water system.

Try one of these:

I guess a lot of the reasons for having an air compressor have to do with what else you can use it for. I bought mine to run air tools but use the same one to paint. To do that, I bought a small filtering and regulator kit that I plug in line on the compressor output. I would think if the filter output is clean enough to paint with, it ought to be OK for winterizing, too. The regulator allows me to decrease the pressure to about 45 lbs (instead of the normal 100+ output) to winterize and anyting else that I want to do that benefits from a lower pressure.

I use air to blow the water out of mine. After draining I leave the faucets open, then stick the air nozzle in the faucet and blow air through the lines forcing the remaining water to drain out. I use the full 90 psi and a rag to help seal off while doing this. since you don't pressurize the lines you don't need to worry about the psi. I also blow out the traps in the drains this way too, then pour a little antifreeze in just to be safe. Remember if you have those hose and nozzle type shower wands, you have to unhook them so they can drain or they'll freeze. Don't forget the outside shower either, same deal.

As to your original question about oil-less, that pertains to the compressor, it doesn't make any difference, they are just talking about whether the compressor has oil in it or not for lubrication of the compressor. I would probably go oil-less if I was going to carry it around, if putting it in the garage and leaving it there it doesn't matter except you need to change it every so often.

Thank's Tom. So, even if the compressor is oil-less, you don't get oil in the air. That's what I was wondering.

When you blow yours out with air, does that get the water out of the pump? You still have to bypass the water heater and drain it by hand, right?

Wow, you do have lots of toys!

Thanks again,

Oops. I meant to say even if the compressor is NOT oil-less you don't get oil in the air.

The vacuum idea is sort of interesting.

Everyone has their own method and as long as they work they are all fine. I do use a compressor. I set it at 40psi. It has a clip on air chuck and I have a "blow out adapter" that screws into my water inlet. I do this after draining my tanks. I put a little "pink" in the traps and in the holding tanks. This is so fast and easy I do it every time I camp in this fall weather.
