Home inspection questions.

Yeah but what are you going to do about it? Most pipes under slab should be drain pipes, but I see them collapse regularly.

Had the inspector caught it, I would of walked away from the house.

This "extra" drain line was the drain for the sink in the kitchen that Tee'ed off the main under my slab. When water went down the pipe my sump well would fill with the water from the sink and the sump would kick on.
