Winter Use

[Palomino_G210]

Use an oilless compressor to blow out the lines because if any oil gets into the water system from an old compressor say, water will have a taste and odor for a while to come not to speak of the health consequences of consuming compressor oil.

Thanks for all the good advice. Do i need to disconnect the water lines from the washing machine when i blow out the lines or can they stay connected?

If you disconnect the hot and cold supply lines from your washer, be prepared to deal with the water that remains in the lines if you do choose to blow your lines out. The washer lines are inside the unit and not outside like most other drain points.

I had to winterize my coach twice last winter for a situation similar to yours. I personally am not a fan of the compressed air method as you always have the potential of having some parts of the water supply system that may not have proper fall and could be subject to any remaining water pooling and freezing, especially over the length of a unit like a motorhome. Winterizing a unit is no big deal but you have a certain sequnce to follow if you want to ensure your unit from freeze up.

Okay okay, you're right, I run the water before reseting the bypass valve. I do use shore water during the winters up here in Washington (with heat tape on the hose) which still leaves a little anti-freeze in the pump and the water lines close to it. As I said, I have never had a problem with freezing water lines and this is my third MH up by the Mt. Baker area.

Luckily I have found an indoor storage facility with electricity for the winter. If I leave my motorhome connected, how do I keep the coach batteries from frying.

We're getting ready to head out next month moving to anchorage, AK. We're dragging the TT with us and we'll be using it as our residence for a month+. I'm planning on blowing out the lines at night if the temps get below freezing. I've got a big dewalt compressor that I really don't want to take with me as weight and space are going to be a factor. Does anyone know/or has anyone tried the small 1gal type air compressors for blowing out the lines? (DeWalt - D55140 - Heavy Duty 1 Gallon 135PSI Max Trim Compressor) Is this size sufficient, or is it just too small for this type of job? I'm not sure how long it can handle pushing 35-40 psi thru the lines.
Thanks, Gabe

Hey_nav,

I use a 3 gal craftsman and I can get the job done but not sure I want to go smaller

[copsuno]

The air pressure method only takes a few mins, a small compressor can handle it. I use a craftsman 150psi and set gauge at 40 psi and works fine.

We have a GT 378 2012, I live in Quebec and I prefer to go with the plumbing liquid, it take about 15 minutes to winterize including washer/dryer and frigo except you have to wait 1 or 2 cycle for the ice-maker machine...

I do not want to take any chance and it depend if you live in the North and how cold is the temperature in the winter.
