Can I tie in my shower and lav to my 3" horizontal water closet drain? My shower and and lav are at a higher elevation then the water closet drain. But the shower is wet vented by my lav and the water closet is within 9' of the vented vertical stack.
The water closet drain runs below the floor joist and is concealed with a soffit, the lav and shwr are running through the floor joist at a higher elevation .
