Hi,
Can you check my DWV rough-in?
I've attached a sketch of the roughin with the non-obvious fittings labeled, along with the bathroom layout. To give a scale, the upstairs full bath on the right is 6.5'x6.5'.
The 3" branch that everything drains into will run in a soffit below the joists. I'm trying to keep everything else in the joist space. Exterior walls are along the bottom and left. The upstairs 3/4 bathroom on the left might not get put in, so the venting on the right needs to be sufficient on its own.
Two things I'm concerned about:
--Is the venting for the toilet sufficient/correct? I read something about needing extra venting when there's a fixture after the toilet.
--Does the upstairs stack empty into the downstairs stack (next to 1/2 bath) correctly? Something about the upstairs waste emptying into the stack below the downstairs waste--so do I need two stack in parralel past the downstairs toilet?
Thanks!
