A leaking basement is certainly no fun, but finding the source of the leak can be harder than actually fixing it. If your basement is leaking but you don't see an obvious source of the problem you may be overlooking a common source of basement leaks: your chimney and fireplace. This is what you should know.
Water can find its way from the ash pit into the basement.
Underneath your fireplace is a space called the ash dump, which leads to a metal sheath that's known as the ash pit.
