How to Install A Utility Sink Next to Washer ?


1. Measurement of Drain 

The drainpipe measurement is the first step in the process.

This step is necessary to determine how far the pipe’s connection is from the ground.

Locate your existing washer line, paying special attention to the place at which the drainpipe joins the wall or floor.

Now, using the measurements you just took, write a mark on the drainpipe of your washer where the water will come out. This is the precise position at which the Y-fittings must be connected.

This Y-fitting will assist in separating the drain from the washer from the drain from the utility sink.

2. Drain Pipe Cutting

The next step is to cut the existing drain pipe. This will be determined by the mark you previously placed on the venting pipe. This connects to the drainpipe above it.

Additionally, you will be required to cut the horizontal T-fitting while doing this operation. At this moment, the water from the washer begins to flow down to the bottom of the drainage pipe.

Additionally, smoothing or deburring the pipe from the inside using sandpaper or another instrument is important to guarantee that the boundaries are smooth and even.

Those grooves and burrs can interfere with the pipe’s seating ability if they are not carefully removed. Ensure that the tube has been appropriately smoothed out before proceeding to the following step and attaching it.

3. Install the Y-Fitting 

Connect the Y-fitting to the nearest drain pipe. Attach one wing of Y to your washer horizontally where the drainpipe is located. Connect the opposite wing of Y to the tubing that emerges from the sink’s drain.

Finally, connect the top of Y to the venting drain on the roof.

To avoid leaks, use a plumber’s glue to seal all of the connections established here. When applying the plumber’s glue, make sure you use a generous amount. Finally, double-check that all connections are tight, secure, and waterproof.

4. Locate Water Sources 

The drains have now been placed where they belong. You must now repeat the process to connect to the water supply.

It’s now time to find the hot and cold water pipe connections in the vicinity of your washer. These connect to a single water pipe fitting. Each of the hot and cold hookups has a water line that has to be disconnected.

If you don’t attach the fitting and the pipe is longer than it should, you’ll have to cut it. Place a bucket on the floor so that water drops do not fall into it; otherwise, water may spill. So keep a mop on hand in case this happens.

Between the washer and the utility sink, cut the tubing in half. Use the threading tool to stitch the pipe.

5. Join the Pipe Splitter to Cold And Hot Water Pipes

With a two-headed brass pipe splitter, screw the splitter onto the main water pipe for each hot and cold line. Ascertain that the seal is complete and that this one is screwed properly.

A wrench can be used to ensure that the attachments you’ve created are sealed and secure. You now have two distinct water lines for the hot and cold pipes; one will lead to the sink, while the other will lead to the washer. Additionally, the splitter must be linked to both cold and hot water pipes.

Once you’ve secured the connections correctly, reconnect the washer to the waterline. Make sure the lines are reconnected with a wrench or pliers once more.

6. Connect Hoses to the Sink

At this point, you’ve completed the majority of the steps necessary to connect the washer and utility sink. All that’s needed now is to connect the hoses that will supply your utility sink with hot and cold water.

Take the tubing from your toolbox now. Then figure out how long it will take to attach the splitter to the water pipes. Choose a red tube for warm water to mark the water lines. Choose a blue one for cold water as well.

This is where you’ll find all of the steps. After that, you must check for leaks in all of the small spaces and confirm that the water pressure in the taps is sufficient.

Check sure each tubing is connected to the correct line before tightening it with a wrench for a more secure, leak-free connection.

Turn on the main water supply and inspect any leaks, which should be repaired as soon as possible. Also, check to see if the water is flowing evenly and rapidly.


That’s how you put a utility sink next to your washing machine. This solution not only saves time but also saves water and space in your laundry room. You don’t have to hire a professional plumber to install the utility sink next to the washer.
