We've just discovered a water leak from the upstairs bathroom,
going through the dining room ceiling and walls and eventually
onto the wooden flooring downstairs. The crew that came in today
to do the initial cleanup, drywall removal from the ceiling, etc.
reported that they found the cause of the leak. Apparently some
sort of animal (rat, squirrel or ???) chewed into the ABS plastic
drain line from the upstairs fixtures and allowed water to damage the
downstairs.
I've never heard of an animal attacking a drain line before. Is this
a common (or uncommon) occurrence?
