I am working on my little piece of paradise and getting the plumbing roughed in is coming up fast.

I have come up with a quick sketch of what I believe to be an appropriate system drawing but if someone could tell be if I get or if I completely misunderstand all this.

I have not indicated the various traps and what not as of yet, just seeing if my understanding of the drain/vent is okay.

Here is the sketch:

Solid lines = 3"
Dashed lines = 2"
dash dot dot = 1-1/4"
green = drain
cyan = Vent

Thanks,

Am I seeing it right that there is only one vent, and that at the end of the drain?

That is what I was thinking. Tie all individual vents back to the stack.

Never mind. I see it now. You are basically venting every drain and tying it all into the stack. I'm no plumber, but I would think that would work fine. There is a plumber on this site who will hopefully chime in here soon.

Thanks, I will keep watching. :)

Checking your local building codes can be a good guidance, as well as an inspector who will no doubt advise you as you go. Assuming you have a permit for the work and submitted a plan.

Is this a new build or renovation?

Thanks for the idea, I will check with the local municipality and see if they can offer suggestions.

This is new construction outside of the local municipality so there is no permit required. I should have said septic instead of sewer on the drawing.

Thanks.

LMT, there is a guy names MassPlumber2008 on this site who is a licensed plumber. I had hoped he would comment, but for some reason he has not. But Tal gave you some good advice that will hopefully prove useful.
