How to blow out lines to winterize
Hello. I have always paid to winterized my RV but would really like to learn how to do it myself without just pouring antifreeze down the toilet and sinks. I would really like to use air on the lin...

Well, I was one that swore the pink stuff was fine ( and it "was") and enough. That was until this spring when hooking up the water. I always have done my RV's with the red pop.
We had a water mixer that was bad and needed replacing which I had the dealer replace this spring. When they hooked up to city water the system wouldn't hold pressure. Yep, a split line by the water heater.
Before anyone says I didn't do it right, I pumped way more than enough red pop into the lines and made sure it was coming through the washer and fridge lines.
But I think it was the city connection as the red pop is pumped by the water pump where I hooked up. So if there was water left, it was from that line and gathered at the low end ( at water heater). Now air pressure would have blown it out of that line most likely as it is hooked up there.
My question is how does the red pop or air pressure feed back through the line coming from the water tank. I never have seen red pop feed back to the water tank. One would think water accumulates their. Unless the low point drain empties that line, which then would explain it.
Anyway, this year the dealer is doing mine as if it fails in the winter its on their dime to repair in the spring. The mildew smell after the water got inside the closet area has been difficult to get rid of.
I don't think one is better than the other ( except the air method clears the water line from the outside connection), you just have to make sure everything gets a air blast or red pop. If I had a way to pump red pop into the city connection it wouldn't have happened.
