Installing a garage sink

My wife wasn’t happy with my bad habit of washing my dirty oil covered hands in the kitchen sink. I’m quite bad at cleaning up after myself, even when I’m cleaning up after myself.

I was lucky enough to my my washing machine right next to the garage. I cut some drywall out to expose the hot, cold, and drainage line. I tapped into all of these for the sink.

In this picture the garage is too the left about one stud bay away, I am sitting where the washing machine normally does.

I opted for sharkbite fittings because my brazing skills suck and I would most certainly light the drywall and studs on fire trying to get tees installed. I had to bend the pex around the back of the drainage line, thankfully I didn’t braze them and could simply rotate the connector a bit to accommodate the bend in the pex.

If you can’t tell, there is a massive dryer lint / cobweb infestation in the crawl space under the washing machine. The previous owner never noticed the dryer exhaust ductwork had come undone, the dryer was pumping moist warm air into the crawl space.. Everything around there was covered in lint and spider webs! I teed into this drainage line and ran the pipe out to the garage as well.

It’s like a haunted house under here!

Here both of the water lines are running through the wall and have their braided hoses ready to attach to the sink. The drainage lines has been run into the crawlspace to connect to the washing machine drain.

After a few trips to Menards to get the required hardware I decided to get a flexible fitting for the drainage and water connections in case I need to move the sink in the future. Here you can see the drainage line very close to the floor running through into the crawlspace.

After the installation was complete I replaced the removed drywall, then taped and mudded it!

Now to clean all this mess up!
