Winterizing on a late model Airstream

Is it Really necessary? Plastic lines right? Fittings also?

It will be down to 24 degrees here tonight, I dont want to winterize my 2010 Airstream because we are going to use it next weekend. Plus not going to be that cold the rest of the week.

Just curuios whats the solution?

Turn on the heater and open the cabinet doors?

If you want to take the chance. Drain the fresh water tank and water heater also. If you have low point drains on your system open them and open all taps to let air in and lines will drain. Don`t forget toilet and shower. After fresh tank is drained run pump a little to empty it. Leave the heat on (it will cost you more in propane than plumbing antifreeze). Leave the taps open to allow for expansion. Good luck.

hi shane,

knot going INTO the procedure 4 winterizing...

since it is in the owners manual and posted here a bunch o'times.

besides, now that its below 32, it's too late for line draining or tank draining.

daytime high was 17 today,

and it will be UNDER 10 degrees tonight in da'hood**

furnace is ON set to 50 degrees,

with one small 700 watt oil/radiator space heater running in the hallway.

the water heater is ON, set to gas.

fresh tank is 3/4 full, waste tanks 3/4 empty.

i expect nuttin 2 freeze, except the exterior waste valves which are closed.

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.

We don't winterize because we rarely hardly ever have a hard freeze in Tucson, and certainly for no prolonged period... We did have one a couple of weeks ago...I turned on the furnace to 40 degrees and left it there all night....we opened the closet doors and drawers and left the hot water heater on. Before we went to bed we ran hot water through all the lines...and we were not hooked up to city water. I turned off the water pump and opened the faucets. It got down to 22 that night be we did not freeze inside or out. Our rig is somewhat protected from the elements, and that helps. I don't worry about 24 degrees unless that is a day time prolonged temperature...and that's just not going ot happen in Tucson.

While the PEX tubing will withstand repeated freezing and thawing without damage the fittings will not.

Exactly where the point is where winterizing is necessary is tough to gauge because it depends on daytime highs, amount of wind, and so on. 24 degrees is pushing it although obviously if you run the heat you'll be fine.

Thanks, I slept in her last night! In the driveway. I love it!!! No sense on wasting that propane...LOL

I thought the PEX tubing would be ok on the later models, and since the tanks are not full of water, shouldn't worry about that either.

I believe I was worring for nothing, since I live in Texas. An occasional freeze shouldn't hurt anything.

It gets plenty cold enough here in the Metroplex to take basic precautions. When it's forecast to be 28 or lower, I open the hot/cold low water drains, drain all the holding tanks, drain the water heater (by letting it siphon out when you open the blow-off valve), open all the taps/shower, press the toilet flush and lay the shower hose on the floor. I then unscrew the pump inlet hose, run the pump for a minute or so.
Now that I'm done with it for a few months, I poured about a cup of RV antifreeze into the kitchen sink traps, bath and shower traps and about a half cup in the toilet bowl last weekend.
When I lived up north, I would blow out the lines as a final step but here in TX, any residual water won't pose a problem. Speaking of residual water, when I put the trailer up for the winter, literally up, as on jack stands, my method of dropping the tongue all the way down coaxes a few dribbles of water out the low point drains.

Shane - since you made it through the coldest night so far this winter, you probably already know what you need to do if you want to keep camping this winter.

If the forecast is for below freezing temps, I keep it simple. Set the furnace to 40 degrees and let the heater do the work.

My trailer hasn't been winterized since it left the factory. I use it too much in the winter to bother. I probably help out the propane company a bit with an extra tank or three of their product during TX cold snaps but I'm ready to roll on a moment's notice.

The lowest confirmed temperature I have seen while following this strategy was 11 degrees. Even though the winds were howling that night (gusting to 40), the trailer suffered no ill effects.

I check and then double check to make sure I have power (furnace blower eats a lot of 12v juice) and propane any time cold weather is in the forecast. YMMV though ;-)

AMEN to that.

And even if the plumbing is fine you WILL screw up inline the filters in the kitchen sink... and some units also have them in the bathroom. Not all that cheap to replace. Pull those out and store inside, and use an air compressor to blow out the joints in the low places.

Today is a gift, that's why they call it the present.

Pink antifreeze is plenty cheap. I pour some in all of the traps. Especially the shower trap since that would be a nightmare to replace.

I take the opportunity to drain the water heater and empty the line to the outside faucet. I open the low point drains and the fresh water tank drain, then blow out the lines. I leave the heat pump on set at 40 degrees, it will change over to furnace if it gets cold enough. I also take out the water pump filter and empty it and clean it. I run the pump briefly without the filter to get water out.

It takes less than 1/2 hour to be sure my plumbing is safe.

My main concern is the occasional ice storm where power may go out and the trailer is hard to get to.
