I'm adding a sink to my basement for brewing and need to tap into an existing drain. I think the easiest thing to do would be use the drain pipe from the laundry room since that's exposed in the brewing area. Here's where the laundry drain comes into the basement from above:
The left shows the drain coming down through the floor and then drains to the left after a few 90s. The right picture is just to give an idea of where the pipe runs to the left towards the main drain. I'm trying to determine the best place to tap into this drain (i.e. least amount of work!). I'm thinking a wye fitting in there somewhere...not sure if it would be better to leave the 90s as is and tap into the drain to the left more with a wye that's off-center so the sink drain comes in parallel to the pipe running to the left. Or replace the 90 with a wye and have the sink drain come in from the right. I'm having trouble visualizing how it will all come together after cutting pieces out.
