### 4. Turn Off the Water Supply

Before you start any plumbing work, it’s crucial to turn off the water supply to the area where you’ll be working. Locate the shut-off valves for the hot and cold water lines that will connect to the sink faucet. These valves are usually located under the existing sink or near the water meter. Turn the valves clockwise until they are completely closed. To ensure the water is completely off, turn on the faucet briefly to relieve any remaining pressure in the pipes. Keep a bucket handy to catch any residual water.

## Installation Steps

Now that you’ve planned and prepared, it’s time to start the installation process. Follow these step-by-step instructions carefully:

### 1. Assemble the Sink

Most utility sinks come partially assembled. Follow the manufacturer’s instructions to assemble the sink according to the specific model you purchased. This usually involves attaching the legs or pedestal, installing the drain flange, and mounting the faucet. Use plumber’s putty around the drain flange to create a watertight seal. Tighten all connections securely, but be careful not to overtighten and damage the components.

### 2. Install the Faucet

If the faucet is not pre-installed, you’ll need to install it now. Most utility sink faucets are relatively easy to install. Here’s a general overview of the process:

* **Attach the Faucet to the Sink:** Insert the faucet into the designated hole in the sink. Secure it from underneath with the provided mounting hardware. Make sure the faucet is properly aligned and tightened.
* **Connect the Supply Lines:** Attach the supply lines to the faucet tails. Use Teflon tape on the threaded connections to prevent leaks. Tighten the connections with an adjustable wrench, being careful not to overtighten.

### 3. Connect the Drain

Connecting the drain is a crucial step to ensure proper drainage and prevent sewer gases from entering your home. Here’s how to do it:

* **Attach the Tailpiece Extension:** Connect the tailpiece extension to the drain flange. Use Teflon tape on the threaded connection to prevent leaks. Tighten the connection with an adjustable wrench.
* **Install the P-Trap:** Attach the P-trap to the tailpiece extension. Make sure the P-trap is properly aligned and positioned to catch debris and prevent sewer gases from escaping. Tighten the connections with an adjustable wrench.
* **Connect to the Drainpipe:** Connect the P-trap to the existing drainpipe. You may need to cut the drainpipe to the desired length using a hacksaw or pipe cutter. Use a coupling to connect the P-trap to the drainpipe. Ensure a secure and watertight connection.

### 4. Connect the Water Supply Lines

Now it’s time to connect the water supply lines to the faucet. Here’s how:

* **Attach the Supply Lines to the Shut-Off Valves:** Connect the other end of the supply lines to the shut-off valves on the hot and cold water lines. Use Teflon tape on the threaded connections to prevent leaks. Tighten the connections with an adjustable wrench.

### 5. Mount the Sink (if applicable)

If you’re installing a wall-mounted sink, you’ll need to mount it securely to the wall. Here’s how:

* **Locate Wall Studs:** Use a stud finder to locate the wall studs behind the drywall. Mark the location of the studs.
* **Mounting Brackets:** Attach the mounting brackets to the wall studs using screws. Make sure the brackets are level and securely attached.
* **Hang the Sink:** Carefully lift the sink and hang it on the mounting brackets. Ensure the sink is level and properly aligned.
* **Secure the Sink:** Secure the sink to the mounting brackets with screws or bolts. Tighten the connections securely.

For freestanding sinks, ensure the legs are properly adjusted to provide a stable and level base. Some freestanding sinks may include wall anchors for added stability.

### 6. Test for Leaks

Once you’ve completed the installation, it’s crucial to test for leaks before putting the sink into regular use. Here’s how:

* **Turn on the Water Supply:** Slowly open the shut-off valves for the hot and cold water lines. Watch carefully for any leaks around the connections.
* **Run the Faucet:** Turn on the faucet and let the water run for a few minutes. Check for leaks around the faucet, drain, and supply lines.
* **Check the Drain:** Fill the sink with water and then let it drain. Check for leaks around the P-trap and drainpipe connection.

If you find any leaks, immediately turn off the water supply and tighten the connections. If the leaks persist, you may need to disassemble the connections and reapply Teflon tape or plumber’s putty.

### 7. Caulk Around the Sink (if applicable)

If the sink is installed against a wall or countertop, it’s a good idea to caulk around the edges to prevent water from seeping behind the sink. Here’s how:

* **Clean the Surface:** Clean the surface around the sink with a damp cloth and let it dry completely.
* **Apply Caulk:** Apply a bead of caulk along the edges of the sink where it meets the wall or countertop. Use a caulking gun for a smooth and even application.
* **Smooth the Caulk:** Smooth the caulk with your finger or a caulk smoothing tool. Remove any excess caulk with a damp cloth.
* **Let the Caulk Dry:** Allow the caulk to dry completely according to the manufacturer’s instructions.

### 8. Clean Up

Once the installation is complete and the caulk is dry, clean up any debris and tools. Dispose of any waste materials properly.
