Where does Alde say not to use RV Anti-Freeze. When I talked to them almost two years ago they said to use it?
The first year and last year I used RV Anti Freeze- blew the lines first and then pumped the anti freeze throughout the entire system. Then last March after returning from FL for the winter I decided to simply blow out and see what happened.
The blowing out worked fine, took longer but worked well. I pushed the compressor up to 60#PSI, then opened a facet. After pressure went down, closed the facet and let it build back up again. Did this a number of times until only air came out. We don't like and don't use the outside shower, so under the dinette I disconnected and capped off the lines so I no longer worry about winterizing it. Temperatures got down to the low to mid teens a number of nights and when we used the trailer no leaks nothing. I did check for leaks before we pulled out by connecting the compressor, building up pressure and then listening for any air escaping or pressure dropping - nothing.
So, next year 2019 when we return from FL I will blow out the lines again, this time in April. Prior to the trailer will be in FL last September so no concerns about freezing.
