My basement floor is leaking!

[Salina Robbins]

Hi everyone,

My tenant notified me of puddles appearing on the floor of the basement unit. After having several quotes done, it seems the problem Is the second unit kitchen sink leads to a drain pipe underneath the first unit floor. The pipe underneath the floor has a crack in it. Which is what’s causing the leak. The first plumber wouldn’t be responsible for repairing the floor. The 2nd plumber says it’ll take about 2 1/2 days to dig, repair the pipe, and repair the floor. The 3rd plumber solution is to cap the drain that leads to the kitchen sink, avoiding having to dig the floor up which he says would take about two weeks and he wouldn’t be responsible for repairing the floor. After he caps the floor drain he would replace second unit kitchen sink pipes with PVC and run a new line through the ceiling instead of the floor.

My concern is mold and sewer flies thriving in the floor pipe that would still have a crack in it Gaining access to unit one. Is that a true concern or am I just being paranoid?

Any advice?
