How To Install A Utility Sink In Your Garage? 6 Simple Steps

You might think that you have to go through a lot of things to install a utility sink. The installation process might be a bit lengthy. But it’s way simpler actually! The method is as straightforward as installing an undermount sink to quartz.

We’ve covered the installation process in 6 main steps for you to understand easily.

Step 1: Shut Off The Water Valve

First of all, you have to turn off the main water shut-off valve. Make sure you rotate the handle firmly. Or else you might need to replace it causing unwanted expense of valve.

Step 2: Measure The Distance Between Water Lines

Now you must determine the distance between the hot and cold water lines. Also, take a measurement of the space where you want to put your sink. Cut two lengths of copper tubing to this length. 

Allow inches more than you need. Any surplus tubing can be taken out later. Despite the fact that copper tubing is robust, attempt to keep this distance under 10 feet. 

From your pipes to your sink, you would like the water to flow easily. Reduce the distance between your sink and the piping. Or else, there might be more chances of leaks. And there’s a chance that difficulties will arise in the future.

Step 3: Secure The Coupling

On the wall, reckon the hot along with the cold water pipes that are exposed. Attach a compression coupling to the end of each pipe with your wrench. Make sure the coupling is secure and doesn’t come loose. 

Remember that you can use a variety of pipes for this.

Take out your soft copper tubing now. Attach one end of one pipe to the compression coupler. Carry on with the other pipe in the same manner. Connect the tube to the coupler with a compression fitting. Using your crescent wrench, tighten these pieces. 

Not sure what type of copper tubing might be ideal for this one? Well, take a look at our suggestions given below-

These are the products you can surely count on!

One tube will hold hot water and the other will hold cold water. Make a note of which is which. So that you can properly connect them when you install your sink and fittings later. You can use a magic marker or a small paper label for this.

Step 4: Locate The Drain Connector

Locate the drain connector vent pipe now. This is normally near the floor and lies lower on the wall. Apply plumber’s putty to the threads of this pipe thoroughly.

Attach the Y fitting’s end with a screw. So one half of the “y” section points down. 

When the putty dries, the seal should be watertight. Screw the drain assembly’s flange section into the Y pipe’s top location. The strainer is included in this. 

Some drain assemblies are included in the purchase of a faucet. They can be purchased separately as well. 

Now, you might want to put in waste disposal. In that situation, you can just obtain a flange extender to bridge the gap.

If you fail to install the drain connector properly, there might be centipedes in the drains.

Step 5: Install The P Trap

Install the P-trap on the other side of the Y. PVC piping is used to make the P-trap. It stops gas or air from entering your drain and generating aromas or odors. 

Reapply the plumber’s putty to these threads to ensure a tight seal. Before connecting the Y component to the main drain pipe, make sure it’s fully furnished. 

This should be screwed on and secured using a plumber’s putty. Always install the pipe at a pitch that allows water to drain properly. Water might not drain downward if it is too level.

Remember one thing! You might not have a p trap. Then you may use an s-trap instead of a p-trap as well.

Step 6: Construct The Countertop

First, measure the sink or use a template that comes with most sinks. As a guide, use these measurements. Then, to match, cut a hole in a piece of plywood. 

Construct the countertop with this component as the base. This would be used to support your sink and attach everything in place with wood nails. Make sure the countertop is well-supported, and consider the size and weight of the sink. 

It’s possible that you won’t need to build a full cabinet behind your sink. You’ll still need a solid foundation to support your sink. To ensure that your sink drains properly, make sure that all surfaces are level.

Step 7: Finish The Installation

Install your sink once the countertop is complete. Then connect water pipes to each faucet handle and install faucet fixtures. Make that the faucet and sprayer head is connected to the correct lines. 

You can skip this step if the sprayer is already placed within the faucet spout. 

Remove any dried silicone or other plumber’s putty that has accumulated. Now, you can turn on the water at the source. And your sink would be ready. 

Now allow one minute for the water to run. Ascertain that no leaks are there behind the sink. Examine the drain, faucet connections, and P-trap. Finally, your utility sink is ready!

These are the steps you need to follow to install a utility sink in a garage.
