Forum Title: Sewer leak under the slab
My neighbor is having problems with their hardwood floors. They are coming loose in several places and some are warping. This has happened over the last few years. I told them there was a possibility the floor installer did not seal their slab before the engineered hardwood was glued down. They had a hydrostatic leak test done and it showed there was a leak in the drain pipes under the slab. I spoke to a friend who is a very experienced plumber. He said that yes the drain pipes are leaking (old cast iron) and this is very common for old cast iron pipes. He also said since they have no smells and no backups at all that the drain pipes leaking could continue to leak for many more years without causing issues and he recommended not doing anything at this time. He also does not believe that without a blockage causing the water to rise to the top of the slab that the floor problem was related to this leak. Sound reasonable??
