Utility Sink addition

[mms1361]

I want to install a much needed utility sink/laundry tub/laundry sink whatever you want to call it, in my laundry room. The house was rebuilt 2 years ago but the contractors didnt put a sink in there. There is a typical laundry machine panel with a hot and cold water line and a drain. To the left of it about 24 inches off the ground there is what appears to be a cleanout. As far as i can see after removing the cleanout plug, the pipe just runs straight up and down with a tee being where the cover itself is attached. It doesnt appear to connect to the washer piping as far as i can tell. Can i simply attach the utility sink ptrap/drain to this using some sort of adapter and use it as a drain?
Ive attached two pictures for a basic shot of what im dealing with. Since the house was rebuilt under insurance the builders used the cheapest things available and didnt leave the house 100% to how it was. So im not sure if this was another thing they didnt want to buy but plumbed correctly. Sorry about all the dirt.. i live in arizona and the rear door stays open half the day.

Sounds like the clean out plug goes directly into your soil stack. Yes you can buy a threaded pvc adapter and plumb your drain directly into it. It is NOT legal. It's called a wet vent and basically only toilets are allowed to be wet vents. that being said it should work fine. me being me, I'd tear out the drywall on that wall and plumb everything where I wanted it.

Depending where in the house your laundry system is, you could always make the new tub (for that matter the washing machine) drain to a grey water system for watering plants...

How handy are you? If you can do a little drywall, solder copper and can cut/glue ABS pipe then you should be able to do it the right way in a day for about $50 or so in materials. Can't solder copper? Look at Shark Bite fittings (although the cost will go up).

Here is a pic of my setup. The clean out is on the left and you can see the sink drain pipe (the long black pipe at the bottom right - not cut yet). In my situation the wall is load bearing so a 1/2 wall was built in front of it to run the gas, water and drain pipes. Yours would likely be some variation but about the same...

@evildky@67carl
Im not really concerned about it being Legal/getting a permit etc. Its indoors and is much needed. Just as long as its functional without consequences. Looking at typical washing machine layouts im hoping mine is plumbed similar to this

.
I cant tell exactly whats connecting to the stack below and above the cleanout. All i know is that the washing machine drain is below the cleanout plug. Either way it looks like i cant just plug in an adapter and call it a day. The cleanout plug sits 24 inches above the ground which is pretty high for most utility sink traps/drains. Looks to me like theres no other way than to cut the wall out other than running some sort of camera through. Idk if i want to do that yet as the home is still under warranty. The last thing i want to do is have to mess with the framing. As for the water supply lines for the sink i was just planning on running a Y splitter to the washing machine supply lines and stealing water from there. Its how i had it connected before and it wasnt really an issue.

@ross
That might be an alternative option to have the washing machine pump grey water outside. The only issue i see is not being able to use the washer drain if the pipe that connects to the stack is too high off the floor to plumb the utility sink to it.
