I've had this about 2 weeks ago, when the water was not filing the toilet tank and the shower was not draining(see my previous thread). It was probably a frozen pipe, because it was very cold. When the weather got warm, they both started working, without any problems, thank God. Now it's the toilet again, water does not come in the tank, the cold water pipe might be frozen.( the shower in front of the toilet is fine so far). The bathroom and bedroom are above the family room but about 5 feet are portruding further outside then the family room, and the toilet is by a corner, so it has walls and floor exposed to cold. We only know that the pipes go down through the family room outside wall, but we dont knoe exactly where, and where is frozen. What can we do now? It's too cold to take the siding off to see if the frozen pipe is in that area. Should we take the wood paneling off in the family room to see what we can do there? we have a fireplace on the next wall that might help or not; will the pipe burst if the heat from the fireplce will warm the walls from the bottom up? How can we survive until spring when somebody can work on it?
