  • is it possible to branch here?

    we are thinking add a counter sink against that wall. it looks like there is no way to branch a drain from the existing setting.

        I swear I need glasses...it took me a minute to see it.

        Anyways, what is that 3" PVC supplying? Is that vented or not?

          Sorry, this detail:

          the vertical line is a drain for first floor kitchen sink. There is a cleanout about 3ft from the ground on that vertical stack. There is a 2" wye which we can see in that photo and is connected by the pvc where I am trying to added a new counter sink drain in. There is another 3" wye which we can see partially and it is not in use now (capped). No other things on that vertical line.

          The horizontal pvc is the wash machine drain from another room which is vented separatedly.

          What I want to do is add a counter sink in that area and want to drain it into that 2" wye. I wish I don't need to drill a new hole on the concrete wall to repipe the wash machine drain in order to put the new pipe in.

            If the 3" PVC line I see in the photo is capped on the other side of the wall, you can use it for your counter sink.

            But you're going to have to drill another hole, so you can install that wye, because I don't think a wye and 1/8 bend will fit...only you will be able to tell.

            If you ever use the 3" branch of the wye down the road, you're going to have to vent it, or you will have 2 fixtures behind a vent, and one trap will suck the other trap.

              Is that silicone on those CI joints?

                It actually looks a little like soil seal..but it looks tan on my computer screen, and soil seal is gray.
