    Basement bathroom DWV layout question?
    Below are 2 drawings of my future basement bathroom. I want to know if my DWV layout plan looks good. I have easy access to a 2" vent that runs all the way to the roof so that issue isn't a big problem.

    Hi there...

    1. The horizontal vent is OK as long as it is sloped UPWARD at 1/4" per foot
    2. Kitchen sink drain has to run straight down and not to be connected to any other pipe below
    3. That 2" vent that "runs all the way through the roof " - why is it going down to the basement floor slab ? Is it connected to something ?
    4. Put clean out on 3" toilet pipe above the slab

    Other than that - looks good...

    Back to you

    Hi apani and Welcome to The Plumbing Page. At AskMeHelpDesk.com.
    Great CAD! Wish I had it. Answer Milo questions 2 & 3.
    Milos code likes lots of vents while mine allows wet vents. If your code allows wet vents I can reduce the number of vents you have to install. I, too. Have a concern about the 2" roof vent. We just don't run a pipe from the basement to the roof for no reason. What's that pipe venting in the basement or is it draining something from above? Let me know. Tom
