All of it should’ve been cut off below the floor and below the traps in straight run areas of pipe and capped not with something like you’re describing but something much more rugged

He capped all the things, I just think the toilet cap is not totally sealed. I taped a piece of thick plastic sheeting over it and then put something flat and heavy over that. The smell is gone. So that tells me the cap wasn’t seated all the way down or something.

It’s meant to be reversible some day. Are you supposed to use a sealant with a cap like this?

No sealant. I did know what you meant. It’s more a temp fitting not for long term use really. I was thinking cut the pipe below the floor and install a screw terminal/clean out. These pipes shouldn’t really just be capped poking up through or even flush with the floor that’s not great if they are.
