Blowing out water lines in Class A
Apologies if this was answered in previous posts. I suspect there is a very simple answer. This forum and YouTube have been very helpful yet I have one open question: I plan to winterize my RV us...

Yes, you want the large volume oil less compressor. just be sure after you blow it out you run the RV anti freeze through it. Too much of a chance of water laying in a low spot and breaking open the line when it freezes.
I personally don`t even use air. I just pump the antifreeze through the system collecting any water/antifreeze in a bowl until it all comes out pink. I only use 4 gallons with this method and that includes putting antifreeze down the drains to fill the traps with antifreeze. 15 years and never a problem. can`t say the same for some of the people that have tried the compressed air route. Some are lucky, some are not!
