Introduction

Plumbing a commercial sink requires a different approach than a residential sink due to the size and complexity of the system. A properly installed commercial sink will provide reliable and efficient water supply and drainage, ensuring your business runs smoothly. Whether you are installing a new sink or replacing an old one, this guide will provide all the information you need to plumb a commercial sink like a pro.

Tools and Materials

Needed Before you start plumbing your commercial sink, you will need a few tools and materials. Here is a list of items you will need:

• Pipe wrench
• Basin wrench
• Plumber’s tape

• Slip-joint pliers
• Copper tubing

Shutting Off the Water

Before you begin the plumbing process, you must shut off the water supply to the sink. The shut-off valve can usually be found under the sink or near the main water supply. Turn the valve clockwise to shut off the water supply.

Installing the Drain

The drain assembly is a critical part of your commercial sink plumbing system. Here are the steps to install the drain assembly:

1. Attach the rubber gasket to the underside of the sink drain.
2. Slide the drain assembly through the sink hole and tighten the nut from below.
3. Attach the P-trap to the drain assembly using compression fittings.
4. Install the tailpiece from the sink drain to the P-trap.
5. Check the alignment of the drain assembly to ensure it is straight.

Installing the Water Supply Lines

The water supply lines are what provide water to your sink. Here are the steps to install the water supply lines:

1. Install the faucet onto the sink by following the manufacturer’s instructions.
2. Wrap plumber’s tape around the threads of the water supply lines and connect them to the faucet.
3. Connect the water supply lines to the shut-off valve under the sink.
4. Tighten the connections with a wrench, but be careful not to overtighten.

Testing for Leaks

Once you have completed the installation of the drain and water supply lines, it is time to test for leaks. Here are the steps to follow:

1. Turn on the water supply and check for any leaks in the drain assembly and water supply lines.
2. Tighten any loose connections if necessary.
3. If there are still leaks, turn off the water supply and inspect the connections for any damage or defects.
4. If you find any defects, replace the damaged parts and test for leaks again.

Common Issues and Troubleshooting

Even with proper installation, issues can arise with your commercial sink plumbing. Here are some common issues and troubleshooting tips to help you solve them:

1. Clogs: If your sink is draining slowly, it may be due to a clog in the drain. Use a plunger or a drain snake to clear the blockage.
2. Low Water Pressure: If you are experiencing low water pressure, check the aerator on the faucet. It may be clogged with debris and needs to be cleaned.
3. Leaks: If you notice leaks in your plumbing system, check the connections for any defects or loose fittings. Tighten or replace the damaged parts as necessary.
