When you’re on the job, you need equipment that’s as reliable and hardworking as you are. That’s why so many professionals trust Chicago Faucets. For over a century, they’ve built a reputation for crafting durable, high-quality faucets that stand up to the toughest commercial environments. Their service sink faucets are no exception, designed for longevity and flawless performance.
This guide is for you, the professional plumber. We know your time is valuable, so we’ve created a straightforward, step-by-step walkthrough for installing a Chicago Faucet service sink faucet. Whether you’re replacing an old unit or installing one in a new facility, getting it right the first time is crucial. Proper installation not only ensures the faucet works perfectly from day one but also extends its already impressive lifespan, preventing callbacks and keeping your clients happy. Let’s get to work.
Preparing for the Installation
A smooth installation starts with good preparation. Taking a few minutes to get organized before you begin will save you time and prevent headaches later. It’s all about having the right tools, the right parts, and a safe workspace.
Gathering Your Tools and Materials
First, let’s make sure you have everything you need within arm’s reach. Rummaging through your truck for a misplaced wrench is a momentum killer. Here’s a typical toolkit for this job:
- Adjustable Wrenches (2): You’ll need two for tightening and holding connections.
- Basin Wrench: Essential for those hard-to-reach nuts under the sink.
- Pipe Wrench: For larger pipes and stubborn fittings if you’re removing an old faucet.
- Screwdrivers (Phillips and Flathead): You never know when you’ll need them.
- Teflon Tape (Plumber’s Tape): For sealing threaded connections.
- Pipe Dope/Thread Sealant: An alternative or supplement to Teflon tape.
- Bucket and Rags/Towels: To catch any residual water when disconnecting the old faucet.
- Plumber’s Putty: For creating a watertight seal between the faucet base and the sink deck.
- Wire Brush: To clean old threads and the sink surface.
- Safety Glasses: Always a good idea to protect your eyes.
- Flashlight or Headlamp: For better visibility in dark under-sink cabinets.
Reviewing the Faucet Parts
Before you tear into the packaging, take a moment to familiarize yourself with the parts included with your new Chicago Faucet service sink faucet. Lay everything out and compare it to the parts list in the installation manual. It’s much better to realize a part is missing or incorrect before you’ve removed the old faucet.
A typical Chicago Faucet service sink model will include:
- Faucet Body with Spout
- Handles (Hot and Cold)
- Mounting Hardware (Locknuts, Washers)
- Adjustable Inlet Arms
- Integral Stops (if included with your model)
- Vacuum Breaker (often pre-installed on the spout)
Check that all components are present and undamaged. This quick check ensures you won’t face any surprises mid-installation.
Shutting Off the Water Supply
This might be the most critical step of all. Before you loosen a single nut, you need to shut off the water supply to the sink. Locate the hot and cold shut-off valves, which are usually directly beneath the sink. Turn them clockwise until they are fully closed.
Once the valves are closed, open the old faucet to drain any remaining water from the lines and release the pressure. It’s a good practice to leave the faucet handles in the “on” position while you work. Place your bucket underneath to catch any drips. For an extra layer of safety, especially in older buildings where local shut-offs might be unreliable, consider shutting off the main water supply to the building and notifying the facility manager.
Removing the Old Faucet
With the water off and your tools ready, it’s time to take out the old unit. This process can be straightforward or a real battle, depending on the age and condition of the existing faucet.
Step 1: Disconnect the Supply Lines
Start by disconnecting the hot and cold water supply lines from the faucet. Use an adjustable wrench or basin wrench to loosen the coupling nuts connecting the supply lines to the faucet shanks. Remember the old rule: “righty-tighty, lefty-loosey.” Have your bucket and rags ready, as there will likely be some water left in the lines.
Step 2: Loosen the Mounting Nuts
Next, you’ll need to remove the nuts that hold the faucet to the sink. These are located on the underside of the sink deck, securing the faucet shanks. This is where a basin wrench proves its worth. Turn the mounting nuts counter-clockwise to loosen and remove them. If you encounter corrosion, a little penetrating oil and patience can work wonders. In severe cases, you might need a nut splitter, but try to avoid that if possible.
Step 3: Remove the Old Faucet
Once the mounting nuts are off, you should be able to lift the old faucet straight up and out of the sink. If it’s stuck, some gentle wiggling might be needed. Years of plumber’s putty and grime can create a stubborn seal.
Step 4: Prepare the Sink Surface
After the old faucet is out, clean the sink surface thoroughly. Scrape away any old plumber’s putty, sealant, or mineral deposits. A plastic putty knife can help you do this without scratching the sink. Use a wire brush to clean the faucet mounting holes if needed. A clean, smooth surface is essential for a good seal with the new faucet.
Installing the Chicago Faucet Service Sink Faucet
Now for the main event: installing your new Chicago Faucet. These faucets are designed for straightforward installation, especially when you follow the steps correctly.
Step 1: Prepare the Faucet Body
If your faucet model requires it, apply a thin bead of plumber’s putty or a foam gasket around the base of the faucet body. This will create a watertight seal against the sink deck. Avoid using silicone sealant, as it can make future removal extremely difficult.
Step 2: Mount the Faucet
Carefully insert the faucet’s shanks through the mounting holes in the sink. From underneath the sink, slide the washers and thread the locknuts onto the shanks. Hand-tighten them first to hold the faucet in place. Before you tighten them completely, check the faucet’s alignment from above. Make sure it’s centered and straight. Once you’re satisfied with the position, use your basin wrench to tighten the locknuts securely. Tighten them evenly, alternating between nuts to ensure balanced pressure. Be careful not to over-tighten, which could crack the sink.
Step 3: Install the Handles
If the handles are not pre-installed, attach them now. Most Chicago Faucet models have a screw that secures the handle to the valve stem. Make sure the handles are oriented correctly (usually “H” for hot on the left, “C” for cold on the right) and that they operate smoothly.
Connecting the Water Supply
With the faucet securely mounted, it’s time to connect it to the building’s water supply.
Step 1: Attach the Inlet Arms
Your Chicago Faucet will have adjustable inlet arms. These allow you to match the faucet to the spacing of the water supply pipes. Attach the inlet arms to the faucet body, using the provided gaskets and nuts. Do not use thread sealant or Teflon tape on these compression fittings.
Step 2: Connect to the Water Lines
Wrap the male threads of the water supply pipes with Teflon tape (3-4 wraps in a clockwise direction) or apply pipe dope. Align the inlet arms with the supply pipes and tighten the connection nuts. Use two wrenches—one to hold the supply pipe or valve steady and the other to tighten the nut—to avoid putting stress on the plumbing.
Testing and Troubleshooting
The moment of truth has arrived. It’s time to turn the water back on and check your work.
Step 1: Check for Leaks
Turn the shut-off valves back on slowly. This gradual increase in pressure helps prevent water hammer. As the lines fill, carefully inspect every connection point for leaks: the supply line connections, the inlet arm connections, and the base of the faucet. Use your flashlight to get a good look under the sink. If you spot a drip, shut the water off and tighten the connection slightly (usually a quarter-turn is enough).
Step 2: Test Faucet Operation
Once you’ve confirmed there are no leaks, test the faucet. Turn the hot and cold handles on and off. Check the water flow and ensure the handles operate smoothly. The vacuum breaker on the spout should function correctly, preventing back-siphonage.
Step 3: Troubleshoot Common Issues
- Low Water Pressure: If the flow seems weak, the aerator or strainers in the inlet arms might be clogged with debris loosened during installation. Shut off the water, unscrew the aerator or inlets, clean them out, and reinstall.
- Drips from the Spout: A brand-new faucet shouldn’t drip, but if it does, it could be due to debris in the valve seat. It may require disassembling the handle and cartridge to clean it. Refer to the manufacturer’s specific instructions for your model.
- Leaks at the Base: This indicates a poor seal with the sink deck. You’ll need to shut off the water, disconnect the faucet, and reapply plumber’s putty or adjust the gasket before remounting.
Maintenance and Care
A Chicago Faucet is built to last, but a little routine care will keep it looking and working like new for years. Advise your client on these simple maintenance tips:
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap and water. Avoid abrasive cleaners, pads, or harsh chemicals that can damage the chrome finish.
- Leaks: If a drip develops over time, it’s usually a sign that a washer or cartridge needs replacing. These are simple repairs, and Chicago Faucets provides readily available parts.
- Professional Help: For major issues or if the client is uncomfortable with DIY repairs, recommend they call a professional plumber.
Your Work is a Lasting Investment
By following these steps, you’ve ensured a professional, leak-free installation that will provide reliable service for years. Installing a Chicago Faucet is more than just a repair; it’s an upgrade. You’ve equipped your client’s facility with a piece of high-performance, American-made hardware that is built for the demands of a commercial environment.
