I'm in the process of adding a sink to the laundry room in my condo and would like a double-check on my plan.
Here's what the plumbing looks like now:
Here's my plan to add the supply/waste lines for the sink:
Basically I would cut out the existing sanitary tee on the 4" common waste line, and replace with a double sanitary tee like this:

I think I'll have to use a no-hub coupling as there is no wiggle room on the 4" line. Was thinking something like this:

Then I'll just make a mirror-image copy of the existing washer waste line on the left side, going up to a washer box. On the right I'll plumb the new sink waste line over to a 90 where it comes out of the wall, with a standard p trap under the sink.
For supply lines I'll cut them off at where they 90 up to the current washer box, add tees for the sink supplies, and continue the lines over to the washer box.
Does all of this look correct? Is there a better solution than the no-hub coupling for the 4" line? I've never used one, not sure how reliable they are.
Thanks for your help!
