Freezing lines anyone?

[Petra]

Will be taking a trip through the Canadian Rockies then down to Glacier and Yellowstone this September. Temps can fall below freezing (as low as high 20's) overnight. We'll stay warm inside witht the furnace, elec blanket and small ceramic heater but I'm a bit worried about the water supply tank water lines being exposed underneath the Fleetwood Niagra we have. Anyone have any experience with freezing their lines? How low and for how long it took. Thanks!

Don't know how long it would take for the pipes to freeze, but since you are using electric blankets, you can also use an electric pipe wrap.  they sell them at most hardware/pluming stores.  it's basically a long thin electric blanket to wrap around the pipes.  it plugs in to a 110v outlet.  you can also wrap the exposed pipes in pipe insulation.  water coming out of the ground should be in the 40-50 degree range (i think).  The insulation might be all you need.  the other option is simply to disconnect and drain your supply hose, and open the drains on the bottom near the hot water heater.  That should drain most if not all of the water from the exposed pipes.  You don't need to be worried about any water in the traps or in the faucets because they'll stay warm like you.

If you keep the PU heated you will be fine.  Heat from the PU will keep the lines from freezing in the temperatures you are looking at.  Enjoy the trip.
