7 Steps How To Install A Utility Sink Next To Washer:

Tools Needed

  • PVC Y-fitting.
  • Hand saws made from PVC.
  • De-burgers and small pieces of sandpaper.
  • Two brass pipe splitters.
  • Wrench.
  • Pliers.
  • Optional threading device.
  • Plumber’s glue.
  • Flexible h.ot and cool tubing.
  • Measure stick.

Step 1 Measure for Drainage.

Before you do anything else, turn off your main water supply. Locate the drain pipe connection on your utility sink. Find the drain line for your washer.

Measure your utility basin’s drain length and mark the washer’s drain lines. This is the place where you will install the new Y connector that will help separate the washer’s drain and the utility drain.

Step 2: Connect the existing drain pipe.

To cut the existing drainpipe, place the mark on the venting line that connects to it. You will also need a horizontal T-fitting to place the water coming from the washer towards the exit drainpipe.

After cutting, use sandpaper- or a knife to smoothen out the insides of your pipe. This is to ensure smooth edges and no sharp edges when attaching pipes.

Step 3 – Attach Y-Fitting. Add Laundry Sink and Washer Drain.

Attach the PVC PVCY-fitting onto the existing drain pipe. One arm of a Y will attach at the horizontal flow where your washer drains exits. The top of this Y-fitting attaches to the venting tube above.

The other side of the Y fitting will attach to a drain pipe from your utility water supply. Use glue or plumber’s putty to ensure all connections are waterproof and secure.

Step 4 Locate Water Sources.

Now that the drain is in position, it’s now time to do the same with the waterlines. Find the hot and cool water pipe connections next to your washer. 

These will be connected to a single pipe. You will need to disconnect the water pipes from the hot and cold hookups at this time.

If you can’t find the fitting or the pipe is too long, you’ll need to cut it. A bucket is handy for catching any water drips.

Cut the pipe to a point that’s halfway between your washer/utility sink. If you are required to thread the pipes at this point, then use a tool that can be used to do so.

Step 5: Add a Pipe Splitter on Hot and Cold Water Lines.

You will need a two-headed splitter for brass pipes. Attach the splitter on the main water line. Make sure that the seal is sealed correctly and that it is securely screwed in place.

Secure the connection with a wrench. This will allow you to separate the hot and cold water pipes using the splitter. One line will be connected to your washer and the other to your sink.

You must attach the splitter both to the hot and cold pipes. Connect the splitter to your hot and cold water lines. Connect the lines with a wrench/pliers.

Step 6 Connect Hoses to Sink.

You will need the longest length of tubing to reach your sink. Then connect the flexible tubing coming from the pipe divider to the cold and hot pipes. 

A red tube is for hot water; a blue tube is for cold. These should be connected with the appropriate pipe. With your wrench, tighten these connections by using nuts.

Final Step.

The last step is to connect the flexible hot and cold water pipes to your utility sink tap hookups. After all, connections have been made, you are able to turn on the main supply.

Leaks should be checked and water flowing smoothly and quickly. If you are making any other changes to the water, make sure to turn off the mains.

Assembling a Laundry or Garage Room Sink Faucet

Tools you will need:

  • Wrench.
  • Pliers.
  • Plumber’s pastry and knife.
  • Foam or rubber gaskets.
  • Washers, nuts.
  • Flashlight (optional).

Step 1 – Turn off the water

If you haven’t turned off your main water supply, do so. This is essential in order to prevent flooding.

Step Two: Mount Faucet, Gaskets, and Putty

Pre-drilled holes should be found under the sink. The hole should be drilled so that the faucet can be inserted from the top. Rubber gaskets are included with new faucets. To make sure the faucet head is secured to the sink, you can use a plumber’s epoxy.

Step Three: Tighten Mounting Nuts

These nuts will fit your faucet at the sink. Start under the sink and tighten the nuts using the wrench.

Sometimes you might see excess sealant or putty when you tighten the faucet to the sink. This can be removed with putty or sealant and a damp towel.

Step Four: Thread Hot/Cold Water Lines

Attach the ends of the hot and cold water line to the matching faucet handles. These connections can easily be tightened manually. A wrench or pair of pliers will also work. Make sure the seals are tightened.

Final Step

Turn on your water and inspect for leaks. If there are any leaks, you should look for any loose connections. Make sure everything fits together tightly, and make sure the faucet’s area is fully sealed. 

Also, you may shine a flashlight from high up to see if any areas are missing or damaged. Before making any adjustments to the water, you must always turn it off.


It’s easy to connect a utility basin to your washer’s drain and water lines. It is not difficult but it is possible with patience, persistence, and follow-through.

Make your laundry room and garage more functional and efficient by using the existing hookups. Because you are conserving water and energy, you will see a significant reduction in your monthly utility bills.

When you work on plumbing, be sure to turn off the main supply. Failing to do so can spell disaster. The hot and cold lines should always be visible.

Mixing the two can cause a lot of headaches for your washer as well as your sink. A professional may be needed, but you can still connect your laundry sink and washer to the same drain if you follow these simple steps.
