Air compressor for winterizing
I'm thinking about doing my own winterizing this year. I'm also planning to resurface my deck at home. Each job raises the possibility of purchasing an air compressor. But I know very little about air...

Perhaps the biggest problem with the compressed air approach is you have to know the plumbing layout in your TT.
If you open the low point and blow out each individual faucet chances are you will drive the water out of the lower point. However, there is no guarantee that there is not some point in the system where the water line tubing sags creating a gathering point for the water droplets left in the pipe.
My TT water system is rather simple, the kitchen sink, bath sink, tub, shower and outside tap are all within 10 feet of the low point drain and I can remove various panels to check for sag points. Others are not so simple.
Still, after I have blown the pipes, I hook the pump input to a bottle of anti-freeze and pump it through to each facet. I need the anti-freeze for the P traps anyway. It is kind of a belt and suspenders approach but it has worked so far.
Just be thorough and allow the air to flow through the lines at 30-35 PSI. Any water that remains will not be enough to expand and cause any problems. I've been using compressed air method since 1987 and never a problem. In fact on my current rig it gives a choice (either/or) in the owners manual. The compressed air method makes is so much easier to de-winterize in the spring.
