How to Install a Utility Sink in the Garage

Join the utility sink.

  • Add adjustable feet to the feet.
  • Check drain pipes for venting.
  • If you can, add venting.
  • Lay the drain pipes.
  • Cut out a portion of the PCV or ABS drain pipe that will attach to the utility sink.
  • Occasionally it is required to cut out old drain pipes. However, this is usually unnecessary, but when required, have another set on hand. A new 1-1/2-inch P-Trap drain will allow you to connect from the new sink to the drain pipes.
  • When new plumbing is required, dry the sink and identify the new drainpipe outline on the old drain pipe.
  • Cut the new plumbing pipe to size. Then deburr it using a sharp knife.
  • Grab the new PCV fittings and stamp them on the inside of the bucket. Then stamp on the outside of the PCV pipes. Proceed to glue them together. In the case of ABS pipes, only ABS cement is required.

Install the sink.

  • Locate the place where you want to install the sink and place it.
  • Check that the leveling is good on both sides and front and back. It doesn’t matter if the floor is cement or ceramic tile, as the adjustable feet will help you level the sink with those types of floors. Secure it against the wall.
  • Proceed to install the old or new faucet on top of the sink. Here we recommend a stainless steel faucet that will last longer. Older faucets may require the old block support that clips into the holes in the sink.
  • Proceed according to the instructions for attaching new faucets to sinks. Use plumber’s putty or silicone to adhere it to the tub.
  • Every utility sink has a sliding nut and gasket. On the inside of the drain piece, you add the gasket. You can also add it to the plastic extension pipe. Then consolidate the pipe inside the sink using the slip nut.

Connect the water supply lines.

  • Take a pipe cutter and cut out the old copper tubing.
  • Scrape the fittings from the inside, the copper pipes, and the edges of the sand pipes. Use flux on the copper pipes and internal fittings.
  • Heat the pipes with MAP Gas and use solder until it penetrates the pipe.
  • As a solder residue will remain, grab a damp rag and smooth it out.
  • PEX pipe is sometimes used as well.
  • Activate flexible stainless steel water supply lines to the faucet and copper piping.
  • Return to open water main and check faucet and drain.
  • Fix any leaks at the faucet or the drain pipe joints.
