Hello everyone! 2 parts to this. Part 1. I manage a 3 story apartment building. One of the bottom floor tenants has a toilet that overflows with foam suds every few days. Started about a month ago. Tenants above claim they have not changed laundry detergent types or laundry habits in the last few months. Had a plumber come out and he snaked the drain lines; laundry to toilet and toilet to street. Same problem. Came back and sent in camera. Pipes are old but doesn't look clogged. He doesn't know what to do so recommends another plumber. Part 2. 2nd plumber comes out and sends cameras down pipes. Says vent 2" vent stack closed up a little due to build up which is causing the issue with the foam. They send me an estimate for $17,486.57 to clean (2) 2" x 25' stacks which, according to them, will fix the problem.
1. Since the pipes were already snaked and cameras showed looked clear, sounds reasonable that the vent stack could cause this issue. Agreed or no?
2. $17,486.57 for that scope of work?!?!?!?!?!
