I want to add a utility sink next to the washer in the garage. I have already plumbed in the supply lines for the sink, but I'm not sure how to install the drain. Currently, working from left to right the the washer drains into a 4" pipe with a P-Trap then extends horizontally about 12" then tees into the vent/drain pipe. About 8"-10" below this is the clean out which opens to the garage and sits just above the slab. The garge floor sits about 8" below the current clean out. The sink will be placed to the right. So my question is can I insert a new tee fitting above the drain pipe for the washer for the clean out, and use the original clean out access to attach the drain for the sink? Would I need to add a vent line that I could splice into the drain line for the washer and up and into the original vent pipe? Is so, are there specisific distances and lengths that should be used?
Thank you!
