Safety Information

Always observe the following safety precautions during installation and maintenance:

  • Turn off the water supply at the main shut-off valves before beginning any work.
  • Wear appropriate personal protective equipment, such as safety glasses and gloves.
  • If you are unsure about any part of the installation process, consult a qualified plumber.
  • Ensure all connections are secure to prevent leaks.
  • Do not overtighten connections, as this can damage the faucet or plumbing.

Installation

Tools and Materials Required (Not Included):

  • Adjustable wrench
  • Basin wrench
  • Plumber's putty or silicone sealant
  • Screwdriver (Phillips and flathead)
  • Thread seal tape (Teflon tape)
  • Safety glasses and gloves
  • Handles (lever, cross, square, or wristblade options)

Pre-Installation Steps:

  1. Turn off the hot and cold water supply valves under the sink or at the main water supply.
  2. Remove the old faucet, if applicable. Clean the sink surface thoroughly.
  3. Ensure the mounting surface is clean and dry.

Faucet Installation Steps:

  1. Prepare the Faucet Base: Apply a thin bead of plumber's putty or silicone sealant around the underside of the faucet base plate.
  2. Mount the Faucet: Insert the faucet body and valve stems through the holes in the sink or countertop. Ensure the faucet is centered and aligned.
  3. Secure the Faucet: From underneath the sink, slide the rubber washer, metal washer, and mounting nuts onto the threaded shanks. Hand-tighten the nuts, then use a basin wrench to firmly secure the faucet to the sink. Do not overtighten.
  4. Connect Water Supply Lines: Attach the hot and cold water supply lines (not included) to the corresponding valve stems. Use thread seal tape on the threaded connections and tighten with an adjustable wrench. Do not overtighten.
  5. Install Handles: Follow the instructions provided with your chosen KOHLER handles to install them onto the valve stems.
  6. Connect Drain Assembly: Install the drain assembly (if included with your sink or purchased separately) according to its specific instructions.

Operation

After successful installation, operate the faucet as follows:

  1. Restore Water Supply: Slowly turn on the hot and cold water supply valves.
  2. Check for Leaks: Inspect all connections for any signs of water leakage. Tighten connections slightly if necessary.
  3. Flush the Faucet: Turn both faucet handles to the full open position and let the water run for several minutes. This flushes out any debris that may have entered the water lines during installation.
  4. Adjust Water Temperature and Flow: Use the hot and cold handles to control the water temperature and flow rate to your desired setting.

Maintenance

Proper maintenance will ensure the longevity and appearance of your KOHLER faucet.

  • Cleaning: Clean the faucet regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the polished chrome finish.
  • Aerator Maintenance: If water flow decreases or becomes erratic, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris, and rinse thoroughly before reattaching. The aerator is designed to be vandal-resistant, but can still be removed for cleaning.
  • Ceramic Disc Valves: The KOHLER ceramic disc valves are designed for long-lasting, drip-free performance and typically require no maintenance. If a leak occurs from the handles, consult the troubleshooting section.
