From Feb through May 2009, we lived with a drain fly infestation trying everything thinkable to locate the source of the breeding. Finally, a sewer company sent a camera down the line and the video showed a clear hole in the pipe beneath the kitchen sink. All waste water from the kitchen sink and dishwasher was emptying under the foundation of the home.
In June of 2009, we began excavation to replace the rotted pipe. The home was on a cement slab and because the floor had radiant heating (copper pipes within the cement slab), we opted to dig from the outside and tunnel under and up to access the leak and breeding area.
