There are a few people in the park I stay in that don't use the anti freeze for that same reason. They blow out the lines with a compressor and leave it. They've been doing it for years without any problems. I'm not going to recommend it. However, they never had a problem. Just make sure if you have a flush toilet, that it's completely empty. One of the guys just put a bottle of anti freeze in his tank after empting the water and flushed. No water just antifreeze. I thought that was a good idea. I'm fortunate in that I have a pump in my trailer that has A bypass for antifreeze. No need to blow out the lines. Just run the taps until you see pink fluid. All done. A word of advice, if equipped, don't forget your outside shower. One thing I learned about the water heaters. There are two different types. One with a drain plug and one with a drain plug with the anode attached. The one with an anode attached takes a socket that is 1 1/16". Ya. I didn't know that!!!! Took a second trip to the park to complete the winterizing. I found some great videos on you tube and herudie site.I know this is an old forum, but I have a question regarding winterizing. I am highly allergic to most chemicals, especially propylene glycol used in anti-freeze. Can I blow my water lines out and not add any antifreeze to them (I am in a very cold climate)? Is there any way for me to check that the lines have been completely emptied?
I am new to this so I would love to hear some of your opinions.
