I am putting in a new walk in shower (ceramic tiled) the plumber came and moved my old drain and enlarged 1 1/2" to 2". Fine. I am worried now that when he cut the old pipe and moved drain... that he cut the drain for the other bathroom tub and the water is going under my slab? Is this possible? Would both tubs (in line) use the same drain? He did not cap the old line?? Help

Simple solution! Call the plumber and ask him exactly what he did. Good luck, Tom
