Sewer backup caused leak at toilet?
Posted by Steve on December 11, 2003 at 01:34:18:
Our main sewer lateral backs up every couple of years, and this time the backup forced a leak at the base of a newly installed toilet. This toilet had not been leaking or showing any other signs of an improperly installed wax ring, but am I right to assume that there is an installation problem? Should the wax ring prevent water that is being forced up the drain line from leaking out of the toilet base in addition to that water which is dispeled during the flush?
