Winterizing
I have a early model 2008 3400RL and I want to blow out the water lines with air...In the convience center, there are two clear plastic PC lines coming out of the trailer and pointing straight down to the ground. On these two lines, there are valves to open and close the lines... What I am wanting to know, are these the end of the water lines loop? Can I open these valves and blow air into the winterize fitting in the convience center and blow air until the air returns back out of these two lines pointing down towards the ground...Or, do I have to go inside the trailer and open all valves and empty each line one at a time??? As you can see, this is my first time doing this and I am not using the anit-freeze method as I am only going to be leaving the trailer for about 4 weeks and I will be right back into the trailer. I am in the Seattle area and I don't really expect that many nights below freezing but I just want to empty the lines as a precaution. Thanks for any help
