  • DIY Commercial Kitchen Faucet Installation

A commercial kitchen faucet is an essential fixture in any restaurant, cafeteria, or food service facility. It provides a reliable source of clean water for washing, rinsing, and other kitchen tasks. While hiring a professional plumber to install a commercial kitchen faucet can be costly, installing it yourself is a cost-effective alternative. This article will give a step-by-step guide for the DIY installation of a commercial kitchen faucet, including the required tools, pre-installation steps, installation process, and troubleshooting tips.  

Before you begin the installation process, following the necessary safety measures is essential. You must wear protective gear, like gloves and safety glasses, and turn off the water supply to the faucet.  

Required Tools  

To install a commercial kitchen faucet, you will need the following tools and materials:  

  • Adjustable wrench  
  • Basin wrench  
  • Phillips and flathead screwdrivers  
  • Plumber's putty  
  • Teflon tape  
  • Silicone caulk  
  • Safety glasses  
  • Gloves  
  • Towels  

Pre-Installation Steps  

Before installing the new commercial kitchen faucet, remove the old one. Follow these steps:  

1. Shut Off the Water Supply 

Find the water connection valves under the sink and turn them off by turning the handles clockwise.  

2. Remove the Old Faucet 

Use an adjustable basin wrench to loosen the nuts that maintain the old faucet in place. Lift the faucet off the sink.  

3. Clean the Installation Area 

Use a clean towel to wipe away any residue or debris from the sink surface.  

Installation Steps  

Now that you have prepared the sink, installing the new commercial kitchen faucet is time. Follow these steps:  

1. Install the Base Plate 

Place it over the mounting holes on the sink and secure it with the mounting hardware provided with the faucet.  

2. Install the Gasket and Mounting Bracket 

Install the gasket onto the mounting bracket and secure it onto the base plate.  

3. Install the Faucet 

Insert the faucet through the mounting bracket and base plate. Secure it with the mounting hardware provided with the faucet.  

4. Connect the Water Supply Lines 

Connect the cold and hot water connection lines to the appropriate valves on the faucet. Utilize Teflon tape on the threads of the connections to prevent leaks.  

Post-Installation Steps  

After completing the installation process, it's essential to take a few post-installation steps to ensure the faucet works correctly.  

1. Turn On the Water Supply 

Turn the valves back on by turning the handles counterclockwise.  

2. Check for Leaks 

Turn on the faucet, then check for any leaks around the base, connections, or water lines.  

3. Test the Faucet 

Test the faucet by running hot and cold water. Ensure the water flow is consistent and the handles are functioning correctly.  


If you face any trouble situation during the procedure of installation or notice leaks after turning on the water supply, follow these troubleshooting tips:  

1. Check for Loose Connections 

Use an adjustable wrench to tighten any loose connections.  

2. Reapply the Plumber's Putty or Teflon Tape 

If leaks around the base or connections, remove the faucet and reapply the putty or Teflon tape to create a better seal.  

3. Replace Damaged Parts 

If you see any damaged parts, such as a cracked O-ring or damaged washer, replace them with new ones.
