    Default Basement plumbing layout REVISED PLEASE HELP June 6th

    Could anyone share any light on this please - its starting to look a bit star trek exhaust.. im sure someone will point out its terrible or maybe not so bad but im also sure it could be simplified.

    I just need to know how to layout the pipes to plumb in the toilet, tub and vanity sink and tie them into the main blue underground pipe.

    thanks for any help - this seems like an awesome forum

    SORRY in the picture it says GREEN DOTT - '2nd floor' that would be 3rd floor loft/attic addition.

    You're right! It is starting to look like a windows screen saver.

    What line coming down is a vent? I.E. continues through the roof without waste dumping into it from an upper floor.

    We can probably get rid of a bunch of the crisscrossing pipes after that is known.

    Nice drawing by the way! What did you use to make it?

    I moved your first thread from the remodel forum up here, so folks could get a good look at the first diagram. It minimizes confusion if you keep all your info in one thread. I am still not clear about the orange pipe. I think we have mentioned that you cannot vent the basement group into a pipe which is bringing waste down from the upper floor.

    We are green with envy over your drawings, however!!!

    answers / questions

    1) the yellow pipe is all new - 'proposed' etc, I was thinking the pipe could drain waste at the bottom and vent at the top for the basement set - could i join this into the 4" stack in the attic?

    2) THE ORANGE PIPE: This is the waste pipe from the kitchen sink, does not serve waste from anywhere else - is vented 6 inches or so above kitchen sink and then goes into the 2nd floor bathroom, dont know if this acts as a vent for anything else/ is not joined in attic or vents through roof! so it seems logical that it would be joined into the 4" stack in the bathroom behind the wall - does that sound right as i cant seem to smell any poopie odours!?


    3) Also could I elimate the 3" pipe serving the proposed 3rd floor addition if i vent the second floor toilet separately?

    Thanks again Redwood/Jimbo for your help on this matter

    drawing done with GF makeup set / 3d max - thanks for the compliments re drawings im just trying to make it as clear as i can...


    thanks

    Hi Tayson - you could also argue p trap for vanity sink - this is just a rough in.

    could you share any light on the waste venting configuration?

    thanks

    I'm no venting expert (or any sort of expert for that matter!). Reason I asked about the tub trap is it is typically in the floor. The vanity P trap would be in the vanity and installed with the fixture.

    I'm also knee deep in a bathroom reno with a pedestal sink, so I have chrome exposed P traps on the brain too.
