But then, I guess plastic sprinkler lines are nothing like an RV water system.
The big difference is that a contractor's compressor, used for jack hammers, etc., are high volume and low pressure. The compressors used for nail guns are generally high pressure and low volume. Some only have 1.5 gal, pancake type, capacity to maybe 20 gal size.
Yes, you can regulate the pressure in the high pressure low volume compressors to 50 psi but understand you have low volume to blow out your lines and will have to repeat the blowing out several times for best results. I did this on my inground PVC sprinkler system in northern Illinois. PVC isn't as forgiving as polypipe.
#1. Blow lines ONLY!! DW has very sensitive taste and could taste pink stun even after a good flush.
#2 typically winterize three or four times a winter. This year twice at most, it has been warm. Just don't like running that much pink stuff.

To under ground sprinklers, most have a drain valve at the low point of the system. When I installed ours this is what I used. You dig a pit at the low end and fill with drain field rock, then the system self drains.
