Winterizing with Compressed air just until freeze is over
Hi Friends, a couple days of below freezing temps here in Illinois. I am still staying in my camper and only want to temporarily blow out the lines, leave the water in hot water tank. I have heated tanks and elbows and covered underbelly. I am taking water filter out and draining the water there and bypassing the water heater and leaving the plug in. Will this be ok ya think? I also am draining the water at my low spot lines, cold and hot. I have seen different ways to do this, do you open the faucets first or after applying air pressure?
