Agreed on the cost, in fact you can justify to get compressor based on 3-5 years payout just for using it for sprinkler system winterization, and in terms of hookup, I used washer connector to make this hose.Originally posted by Tik-Tok
I just hook my compressor to a fitting I installed in the supply line, manually open all the valves, and let it run for a few minutes.
Paying $75 is ridiculous, lol. It isn't like you need to get ALL the water out of the line, so long as the lines aren't completely filled, then the expansion from the water freezing isn't going to burst anything.
