Hi,
I am adding on to my house and a bathroom is part of the plan. I have attached a diagram of what I am planning, and had a couple of questions:
1. As the bathroom is in the center-back of the house, and no access to existing sewer, I have to run the line toward the rear of the house to get around the existing structure, and then around to the front. There is no good spot to put a clean out, so can I call my 4" roof vent the clean out for code?
2. What size should the vent lines be that tie into the main vent (pipes in wall on diagram)?
The diagram shows a side view of the plumbing, and a overhead of the run.
Also, any suggestions or comments on what looks wrong would be greatly appricated.
Thanks much,
Mike
