blowing out the fresh water lines

[pugtug613]

I am in the process of winterizing my R27. I do not like using too much of that pink stuff. I drain the tank and the hot water heater and then I blow out the lines with compressed air. That way, I can add 1 gallon to the tank and run 1 gallon thru the hot water heater. I disconnected the hot side on the water heater and blew out the both sinks.(faucets on hot) I wanted to do the same on the cold water. I disconnected the supply side at the pump and blew air into the hose. Not much came out of either hose.(faucets on cold) It seemed different then the hot water side. I even went to the supply side of the check valve (made no difference). Am I missing something? I really do not want to run pink stuff thru those hoses, it takes too long to get that smell out in the spring. Does anyone else blow out their lines?

Hi there Pug Tug,
Here in the Puget Sound I don,t worry about it too much because my R25 is either in water or heated warehouse.
When I had a trailer though I used to blow everything out with compressed air like you mentioned to get a majority of water out.
I would then hook up the exhaust side of a shop-vac to dry out the lines. I would let it run for hours while I did other stuff The heat from the vac exhaust will dry out a lot of water and very little anti freeze (if any) will be needed on the potable water side. Don't neglect your fresh water pump

Raw water for the engine, wash down pump, exhaust, head etc. be liberal with the pink stuff and follow the winterizing instructions. That stuff is to expensive.

Happy Winterizing,
