Step-by-Step Guide of How to Install a Utility Sink

Step-by-Step Guide of How to Install a Utility Sink

Let us begin the project by following these steps carefully. Before that, you have to keep in mind that installing the sink next to the wash is patience and using the right tools.

At the end of the day, you will find out that the steps are fairly straightforward.

Step 1: Measuring the Drain Pipe Connection

Measuring the Drain Pipe Connection

After turning off the main water supply, start doing step 1. You cannot begin the project when the flow is still going.

Surely, everything would be a mess if you skip that. After it is off, measure the length of the drain pipe connection from the utility sink to the ground.

After getting the sink’s measurement, you need to find the drain line on the washing machine.

When you get the exact position where the line moves down into the flooring or wall, make a mark on the venting pipe.

This position is the exact area to install the new Y-fitting. It acts as the separator of the washer’s drain line from the one for the utility sink.

Moreover, those essential stages give a good flow of water for both features.

Step 2: Cutting the Existing Drain Pipe

Cutting the Existing Drain Pipe

Next, you need to cut the existing drain pipe right from the mark you made before. From the venting pipe, it will connect above the drain pipe.

During the process, cut the horizontal T-fitting too. That is the point where the water from the washing machine will dissolve turning toward and down the exit pipe of the drain.

After you are done cutting them, use the deburring tool for smoothing out the spot inside and outside.

Then, make sure it is clean and smooth so the burrs and grooves will not get in the way of seating the pipe properly. Before step 3, check the smoothness again.

Step 3: Attaching the Y-Fitting

Attaching the Y-Fitting

Attaching the PVC Y-fitting would be the next step. One of the Y’s arms would go to the washing machine’s horizontal flow. Then, the top arm connects to the upper venting pipe.

The last one should go to the sink drain pipe. After all of them are attached, make sure they are tight. Use some plumber’s glue if necessary because it needs to be like that for a really long time.

Further, the recommended product should be waterproof.

The connected pipes cannot tolerate leaking because it would lead to water damage until you fix the problem. This would not be an efficient system for your laundry.

Step 4: Finding Water Sources

Finding Water Sources

After the connections are settled, the next thing to do is quite similar. First, find the cold and hot water pipe connections nearby the washing machine.

They are connected in a single fiction on the water pipe. Then, one thing you need to do is to disconnect the hot and cold pipes.

If the plumbing system does not have that kind of fitting, you may find it in one long piece. Therefore, you should cut the pipe.

Before that, prepare a bucket to catch some water left. Cut it at the middle point.

However, you do not have to thread the pipe if it is not necessary. While needed, acquire a threading tool to complete the steps.

Step 5: Adding the Pipe Splitter

Adding the Pipe Splitter

The two-headed pipe splitter you have already prepared, attach it onto the main water with screws. Have it for both cold and hotlines.

Do not forget to screw them all tightly. The purpose of using a splitter is to separate the water supply based on the temperature.

One of them would go to the wash and the other goes to the utility sink. It is crucial to connect the splitter to cold and hot pipes.

After they are all secured, make sure to reconnect the wash with the piping you already have.

Otherwise, you can get the new ones if you want. Once again, ensure the security of the connections you have already made. Use pliers or a wrench for that.

Step 6: Connecting the Hoses

Connecting the Hoses

This one is one of the final steps of how to install a utility sink next to wash. Take the tubing. The length should be enough to reach the sink.

Connect it to the sink’s line right from the pipe splitter. The blue one for cold and the red one for the hot for easy identification.

After making sure of the secured connection, turn on the water supply. Check the water flow whether it runs smoothly or not.

What about the leak? Ensure this problem is not present. If there are some issues, turn it off again and deal with the leaking connection and tight them up more.
