Not a big fan of running the water for many reasons. I can understand in the house as the water is under constant possible need and you cannot easily flush out the house system, but not really practical for an RV / TT.
1) There is of course the environmental impact and why waste the water. After the reports of drought, etc. and we have the trailers to visit nature, I think we should be doing our part to protect what we have.
2) Flushing / blowing out the system is not that big of a deal. (did mine in just a few mins the other night when the temp was at 32 degrees)
3) There is no guarantee it will work. How much do you let it drip vs how fast it will freeze. I looked at my gutter downspout this morning and it was a solid 2 ft icicle. That water was running all night and still managed to freeze. Don't have much faith in a tin can filled with water in the frigid cold.
On a side note, not a big fan of antifreeze either though. No, I'm not Ule Gibbons, but just the idea of adding a foreign substance to a porous plastic system and then later going to put drink from it. If it puts hair on your chest... better check the bottom of your feet too.
Sorry for the sudden soapbox, but man do I feel clean.

Rivet winter and water

i have done several things for using water in cold months. airstream recomends that the water tank be used instead of city hook up. i do use my furnace as well. i bought a space heater that blows heat thru the duct work so the furnace doesn't have to kick on as much. heat tape is also good on the pipes in back end as the heat from the furnace doesn't get their as well. a second blower type heater may also be used. always keep an eye on things, daily. my 75 furnace works well but sucks down the propane in hte colder weather. no problems so far going on 4 months to present in west virginia. a mild winter.

Ule Gibbons? Didn't he eat Grape Nuts and pine cones? Wait a minute, I'm showing my age.

Blowing out the pipes seems reasonable, but what about the fresh water tank? In my old trailer, there was none (so I did not have to think/worry about it), but my "new" '73, there is a plastic tank midsection in the trailer. I suppose there is a drain somewhere, but the tank is pretty low in the belly. I need to sanitize it anyway as part of my rebuilding, since the filler tube is off, and the tank neck (in the belly) has been open for quite a while.

Get under the trailer and look for a draincock low on the tank -- roadside or curbside.

The tanks are plenty sturdy to allow freezing of a small amount of residual liquid, though I will put a couple extra leveling blocks under the opposite wheels to help it drain the best. Just be sure not to introduce RV antifreeze into the freshwater tank. It'll take forever to get it flushed out! Take out any inline carbon water filters before you pump antifreeze through the system or else you'll be searching for that costly little item in the spring. There are a couple of 'sticky' how-to threads at the top of the winterizing section of forums.
