venting half bath in basement
Posted by Shawn G on April 23, 2002 at 11:15:03:
I am thinking of installing a half bath in the basement of an older house. There is already a 3 inch drain that I have run water down via a garden hose and it ran well. The venting for it has also been started. It is 2 inch but is running in a bad spot. I have no way of getting to the roof except through a bedroom with its course right now. Can I run the vent horizontally for 12 feet or so and then straight up? If I can, what is the best way to run the pipe- right under the floor joists? What exactly is considered the "spill line"?
