How To Install A Utility Sink Next To Washer – 8 Steps

For your convenience, this post has links to Amazon.
The average family garage is much more than a place to put a vehicle. Family members may utilize the room to repair automobiles, store gardening equipment, and work on hobbies such as carpentry.

Installing a utility sink in the garage or next to the washing machine is a cost-effective alternative to trudging through the house to the kitchen sink. This keeps the rest of the house from collecting more dust and dirt. However, keep in mind that a garage without pre-existing plumbing connections would take some plumbing knowledge to carry out the work successfully.

You may accomplish the work in a fairly short period with this step-by-step guide on how to install a utility sink next to washer.

How To Install A Utility Sink Next To Washer

How To Install A Utility Sink Next To Washer

You may find that installing a utility sink next to the washer can be simple. You can install a utility sink next to the washer on your own by following a few simple steps.

Necessary Tools That You Need

Before you begin installing a utility sink beside the washer, you should gather the essential supplies for the project.

After gathering all of the components, you may begin the installation procedure.

Step 1: Turn Off The Water Supply Line

Ensure that you have switched off the main water supply before installing the sink. If the water supply line is not turned off, water will spread around the kitchen area.

Step 2: Measuring For Drain

Determine the distance from the ground to the drainpipe connector. Then, locate the drain line for your present washer, paying particular attention to the point at which it enters the floor or wall.

Make a mark on your washer drain line using the same measurement as you did for the utility sink drain line. Next, you’ll need to install the new Y-fitting, which will be used to separate the washer’s drain from the utility sink’s drain.

Step 3: Cutting and smoothing drainpipe

Cut the existing drainage pipe from the marking to the point where the venting pipe attaches above it. Additionally, it would be best to cut the horizontal T-fitting that connects the washer to the exit drainpipe.

It is now necessary to level out the inner workings of the pipe. Deburr or smooth the pipeline with a tool or piece of sandpaper. When attaching pipes in the following stage, you must ensure there are no sharp or jagged edges.

Step 4: Attaching Y-fitting And Adding Laundry Sink

Connect the PVC Y-fitting to the existing drain pipe. Connect one of the Y’s arms to the horizontal flow of the area where your washer drain is located. Connect the Y-top fitting’s to the venting pipe above.

And the Y-opposite fitting’s arm will connect to a pipe that runs from your utility sink drain.
Secure them firmly using the plumber’s putty or adhesive. Ascertain that everything is watertight and secure.

Step 5: Locating Water Sources

Now is the moment to locate the hot and cold water hookups near your washer. These are used in conjunction with a single water pipe fitting. Next, disconnect the water pipe at the hot and cold connectors.

If the fitting is not correctly attached and the pipe exceeds the specified length, reduce the pipe. Place a bucket on the floor to catch any dripping water.

Cut in the middle of the washer and utility sink. If you need to sew the pipe together at this point, you may do it using the threading tool.

Step 6: Adding Pipe Splitter

Use a two-headed brass pipe splitter to attach the splitter to the main water pipe. Ensure that the seal is complete and that you screw this one firmly.

A wrench may be used to ensure that the connection is secure. The water supply will now be separated from the hot and cold pipelines by the splitter.

The washer will be connected to one end of the pipe, while the sink will be connected to the other. The splitter should be connected to both the hot and cold water lines. Connect the washer to the existing pipes after attaching the splitter to the hot and cold water lines.

Step 7: Connect Hoses

The next step is to connect the tubing from the pipe splitter to the sink’s cold and hotlines, as long as you need to reach the sink. Again, for clarity, the red tube should be connected to the hot connection and the blue to the cold connector.

You may switch on the main water supply again after you’ve made sure all of the connections are secure. First, make sure that the water is running smoothly and that there are no leaks. Make sure that all of the connections are secure before turning the water back on from the mainline.

Step 8: Assembling the Utility Sink Faucet

Now that your sink is connected, the next step is to assemble the faucet. Start by shutting off your main water supply to prevent floods. Then, follow these instructions:

Mount the sink faucet using gaskets or putty. The faucet hole should be pre-drilled in your sink. You may insert it by squeezing it in from above. Faucet heads are often attached to a sink using bolts and rubber gaskets. Use a plumber’s putty to create an even tighter seal.

Tighten the mounting nuts. The nuts that hold the faucet to the sink are called mounting nuts. Use a wrench from the base of the sink to tighten up any loose screws or bolts. Excessive sealant or putty may leak out of the faucet when it is tightened. While it’s still sticky, use a moist cloth and a putty knife to remove it.

Thread the hot and cold water lines. Bring the ends of the hot and cold water lines together and secure them to the undersides of the faucet handles. These connectors may be manually tightened. However, it is usually preferable to use pliers or a wrench to guarantee a perfect seal.

Turn the water on to check for leaking. You have now completed the assembly of your faucet. All that remains is to ensure that everything was installed properly. Reconnect the main water supply and test the faucet for leakage. If you come across any, you’ll want to inspect them for any weak connections.

Ascertain that the space under the faucet is properly sealed and that all connections are secure. Additionally, you may use a spotlight to much more easily find gaps.
