Its my understanding that p traps are required for all bath tubs. I am not sure there is an exception for those that are in concrete. The picture is of a replacement of a bath tub, with the new abs pipe drain installed, connected to the old existing pipe in concrete.
Do they have to install a p trap here? I know that it would be a lot of work to dig out that concrete to do it, or they would have to have the tub raised, which would not be desireable.
