Hi All,
I am currently attempted to finish a full bath with a separate bar sink in my basement. The rough-in for the full bath was completed during prior construction, so I am not sure exactly how the pipes run under the concrete.
Things I do know:
- The shower has a p-trap.
- When I cut the caps off the toilet and shower, the water did not move. As soon as I cut the sink drain open, the toilet drained into the ejector pit. This water was from the prior construction to test the system (they never drained it).
- The ejector pit has a 2" vent line that leads to a 2" vent put in for it. The sink drain has a 1.5" vent line right above it that leads to the next floor. The 2" and 1.5" vent ties together on the first floor before going to the 2nd floor and roof.
I make a sketch of the way I think it is laid out. Based on the suction of the toilet, I assume the sink ties into the main sewer pipe before the shower. Once the toilet drained, the shower p-trap did not siphon off. It appears the sink vent is the wet vent for the toilet.
Question:
- Do I need to break open the concrete and add a vent to the shower, or can it also wet vent through the sink?
- I plan on adding a bar sink to feed into the bathroom sink drain with its own vent to the main stack - is this fine?
I assume since this was new construction (6 months ago), all of this should work, since that is the way to was originally intended to be set up (except the bar sink), but I want to confirm.
Thank you in advance!
