I relocated my shower drain to share a vent with my toilet, all moved across the room from the location of my old tub and shower. Slab on grade, 4" slab over cinders, with wire mesh and rebar and hydronic PEX lines in the slab.
So I've got a 1.5" trap and a 2" trap with a 2" vent still open at the roof all about 3' from the main stack. Most of that 3' is actually vertical. These pipes wye into the main stack nearly DIRECTLY BELOW them.
Meaning that in order for me to cut out this whole vent and its associated drains, I'd need to go pretty deep, and that's a BIG challenge. I've already gone about 12" deep to relocate my toilet and that was a huge hassle.
They are ABS drains, so sealing them is easy.
My plumber wanted me to cut them off under the slab and cap with ABS cement. Leave the vent open.
My worry is that if they ever had any problems, finding them would be a challenge.
I wanted to leave them flush with the floor, with a glued in punch-out test plug, oil in the traps, maybe even a rubber test plug inside. That way, if they ever had problems or we wanted to use them again, we know where they are, and they can be opened up. I don't want to "dynamite" these drains.
My plumber is worried having those caps visible will spook the inspector, and they could "technically" leak gases into the room once the traps dry out. He felt like having them under the floor was a few extra layers of protection.
What would you do?
