Convert standpipe into sink drain?

[nestor87]

Hi -- I've been searching and reading for a couple days and couldn't find a clear answer to this:

As in many posts I've read, I'm trying to add a utility sink in my basement. I'm hoping to use the 2" drain that is now serving as a standpipe for the washer as the drain for the sink. I've seen many threads where people try to then add a new standpipe to the same line, but I'm happy to simply hook the washer hose over the edge of the new sink. Given that I'm not adding a second fixture -- just swapping out a standpipe drain for a sink drain -- can I just saw off the old p-trap, extend the horizontal pipe a few feet, and add a new p-trap below the new sink?

Edit: Photo of the standpipe and trap is attached -- the sink would be where the washer is now, so I'd only need to move the trap over and out a couple feet.

Thanks!

Thanks for joining and posting the forums.

With many new members looking for advice and answers, be reminded that good photos and illustrations always invite an audience that can give faster replies that are less generalized and more suited to your exact needs.

Try to provide at least two photos. Include a closeup of the attention area so we can identify fine details, and include one zoomed out so we can see the rest of the room and things nearby, adjacent areas, floors underneath. Use a black marker to write on blue painter's tape or bright colored Post-It's to mark areas of interest, there is no need to modify your photos with fancy text overlays. Take as many photos as you can, choose the best ones that are clear.

Do include diagrams for plumbing and supply line projects. A scan or photo of a hand drawn illustration done quick on paper is usually easier for most to create than trying to make one in a computer app. We don't need architect schematics, just something simple to help us understand your project.

If the existing standpipe is properly vented, it would work, but the existing trap cannot be raised without raising the connection in the wall.
