Temps here haven't gotten below zero in a few years, but that doesn't mean water won't freeze. We've been below freezing for months at a time, yet every spring when I hook up water, there are no runs, no drips, no leaks. That is because I make sure there is nothing but air left, and what water is left is not enough to do damage. Only use pink stuff for traps.
I hate to correct anyone on this forum BUT leaving the water lines dry after you blow them with an air compressor is not a very good practice. I am telling you from experience. I did that one winter and had to repair a lot of water lines because for one thing it doesn't get all the water out of the lines. on the other hand filling the lines with RV anti freeze, not to be confused with automobile anti freeze which is poisonous, will displace any water still in the lines and protect you down to -50 degrees. they make a valve and hose combo that goes on the intake of the water pump that allows you to fill the water lines with anti freeze. another thing that is well worth the expense is a by pass set up behind the water heater tank. this bypasses the tank so you don't have to use six gallons of anti freeze in the hot side of the lines.
