I have a laundry room on the first floor of our slab style two story home. I would like to add a shower drain to this 3" pipe. I understand that it will have to be with a 2" pipe and a rise of 1/8" to every foot.
Now for the question:
If I put the shower on a platform and tee off of the washer drain pipe after the trap, do I have to add another trap on the drain to the show also?
