I have a general contractor who is constantly fighting me on things. I call him out for crappy work and he hand waves it away saying it’s not a big deal. This bathtub issue is probably the worst of it and I was wondering if maybe you can help me understand it.

We were 1 day away from stucco when I noticed this bathtub issue and took these pictures. In the picture we are looking up to the ceiling above a recessed front door into the floor beneath the bathroom.

If we filled the bathtub up, wouldn’t it just drain into this ceiling area? I think it’s just wide open into the tub and the knockout is on the 4” drain pipe.

I could see up into the drain so I assumed it was not connected and we were about to be in for a world of problems. First he says it’s an alternate drain and it’s done right. Then his plumber comes by and says oh shit this isn’t done and fixes it. Now after the fact he says nothing would have happened because of the knockout cover.

Thank god it’s fixed (hopefully) but I’m trying to get him to acknowledge the monumental failure.

Thanks for your help
