Thread: Need advice on basement layout and toilet venting

    Default Need advice on basement layout and toilet venting

    Slab cutting time is quickly approaching... and I am really looking forward to getting this project started. This forum has helped on all planning aspects, and I am quite greatful!

    Attached is a plan of my future basement bathroom and utility room and am inviting you to comment on it and possibly answer a couple of questions...

    But first, here are some details.
    -Main pipe to sewage basin is 4" diameter ABS, all other pipes are 2" including vents.
    -All connections use either a 4x4x2 or 2x2x2 wyes with 45 degree bends.
    -Vents are colored orange

    1)I haven't figured out yet what would be the best venting route for my toilet...

    2) Not sure if my sink drain is following an optimal route

    3) Is the drain line from the sink (next to the toilet) following an ideal path ?

    4) Is the washing machine connection to the utility sink ok ? Is a 2" pipe sufficient if both are in use ?

    Any comment would be appreciated!

    Default drains

    You are showing what you want to do. Much, much more important is exactly how you will do it and that cannot be shown with that drawing.
