I sometimes go to a temple in Worcester Mass. They've owned the
building for a few years and they said that often times the bathrooms
can't be used in the colder parts of the winter because
the sewer pipe freezes. I told them I'd post a question on the internet
about this to see if anyone has any suggestions.
I wounder if you could dig up part of the pipe and see how deep it was
and then wrap a long heating coil around it and bury it.
You would then activate the heating coil in the winter. Would that be a
bad idea to be running an electric heating coil under ground ?
My guess is the only other thing you could do is pile more dirt on it.
How deep does it need to go ?
Could it be affective to connect the toilet with the hot water instead
of the cold and flush it often ?
