Utility Sink install - Need opinions and thoughts from plumbers
Posted: Sun Sep 11, 2022 11:08 pm
Wanting to install a utility sink in my garage, and facing an issue where a free standing sink is not tall enough, so I either need to raise it (which will look funny) or use the existing clean out.
That made me think of 2 possible options. 1 is going with a free standing using the clean out or wall mounted unit, using the existing laundry drain pipe. I would love some thoughts and suggestions from plumbers as I'm just an average joe who loves DIY projects.
In the second image, I've drawn out 2 possibilities.
Free Standing on the Right: Using the existing Cleanout, I would extend it out so I can add a T to it, so I can add another clean out on it, and then be able to tie it into the sink. My only gripes with this are there are more pieces I would need to get just to achieve this (I believe I would also need an AAV on top of this because of the new line) and it would also look quite weird with the extended cleanout.
Wall mount on the left: I would cut off the existing P-trap on the wall, and utilize the sinks p-trap in place of it. From there, the plumbing would seem extremely straight forward, just tie-ing it from the p-trap of the sink to the wall drain. I think of the 2, the wall mounted looks much cleaner and the plumbing for it would be super easy. I also believe I wouldn't need to worry about an AAV since I would just be utilizing the existing drain, and would be dumping the laundry drain into the utility sink.
