I use a 12 volt portable jump box with compressor, works just fine let a little pressure build up and open faucets one at a time

I use the antifreeze approach.

I also agree that when you are facing barely freezing temperatures, you should not worry too much.

Somebody, please, point me to the road.

I'm not worried about that tomorrow night as I'll keep the catalytic heater going to keep myself warm.

But.... I'm off the grid. No water, and no power except hauling and solar/geny.

So... It's going to be hard to use compressed air to blow the lines... (I've got a 12 volt air compressor, but don't think that will work.)

I need to stay here a couple more weeks. I can deal with camping dry, (although it will suck not to have the toilet at night) just don't want broken lines.
And unfortunately I can't haul it out to go somewhere local to winterize it at the moment.


Just drain the tanks and run antifreeze through and then drain the pump? Or...?

Thank you.

I'm just paranoid about hurting my baby.

I wish the manual was a little more specific, and user friendly...
I thought the furnace was The AC/heater from reading the manual.
(needing 3500 watts)
From an earlier post in this thread I saw the bit about running the furnace... And ran it for a few minutes. (also found the bit about it running the batteries down in a couple nights, and the furnace heating the pipes/tanks))

So tonight Ill run it on 60 (I've got a good sleeping bag and can deal for the couple more weeks I need to be up here)

And hook it to the geny tomorrow night if the solar doesn't bring it back during the day.

I just REALLY don't want to be disassembling my home to get to pipes!

Just to add a little bit of food for thought for you.

We have done a fair bit of late fall camping (it is our favourite time of year) in sites without electricity where overnight temperatures will dip below freezing. The furnace is a battery killer - and this needs to be managed around - our trailer is small (a Bambi) with a single battery.

Our normal routine under these circumstances is to go into "energy conservation mode" which simply means we don't waste any battery power - we try to time the activities that might have a larger draw on the battery to take place when the generator is running. When we go to bed I work to have the battery showing a voltage of 12.6 or higher.

Overnight we turn the furnace down low as you are suggesting and throw on an extra blanket (my job to get up first - turn the furnace up - and get the coffee going). After one nights draw on a frosty night the morning voltage check will rarely show battery voltage of 12.2 or less (once the coffee is on my next job is to fire up the generator).

If I can run the generator every day the usual minimum times are an hour in the morning and an hour in the evening to keep the battery topped up. I've found that when I can't meet that minimum generator time (i.e. weather or schedule) the battery will give me a 2nd night - but I wouldn't want to bet on a 3rd.

I have no idea how solar charging would work into this - but would think that keeping an eye on your batteries voltage will guide you.

And finally - propane use goes up a lot when the furnace is in regular use - I can go all summer without emptying a tank - but during cold-weather camping it is not uncommon for us to go through a tank a week.

Hope this helps.

Good luck,

Thank you very much for the thoughts.

A tank a week for a couple weeks I can certainly stand.

I'm developing an offgrid property with a metal building which will have living space, and serve as a large garage for my airstream... A few things are undone till I'm at the "pause for the winter" point, and I just can't leave quite yet.

I've got the typical pair of 30's, a pair of 20's I throw into the rotation, and a 100 pounder that sits as a reserve (not putting in the building's propane tank till the spring).

I don't use much juce except during the day to recharge my iPad, phone, and laptop. Already put in LED's etc.
(as I sit here in my wool coat and watch cap)

Not worried about me, 8 years as a Grunt... As I said, just worried about my stream.

Thank you all. I bought 3 gal of antifreeze today, and will be picking up a adaptor shortly if it becomes necessary.

I always use antifreeze I do it every week-end with the FW, but with my old tt i had to to push on the pressure valve of the city water connection.
What do you do to have antifreeze in that pipe ?
