4. Setup and Installation
The Moen WS84667BRB faucet is designed for a 4-inch centerset installation, making it suitable for many standard bathroom sinks. Follow these general steps for installation:
- Prepare the Sink Area: Turn off the water supply to the sink. Remove any existing faucet and clean the sink surface thoroughly.
- Install the Faucet: Place the faucet body onto the sink holes. Secure it from underneath the sink using the provided mounting hardware. Ensure the faucet is centered and stable.
- Connect Water Supply Lines: Attach the hot and cold water supply lines to the corresponding inlets on the faucet. Connect the other ends to your hot and cold water supply valves. Hand-tighten, then use a wrench for a quarter turn, being careful not to overtighten.
- Install the Drain Assembly: If your model includes a drain assembly, follow its specific instructions for installation into the sink drain hole. Connect the lift rod (if applicable) to the faucet mechanism.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. Operate the faucet handles to ensure proper water flow and temperature mixing.

5. Operating Instructions
The Moen WS84667BRB faucet features two lever handles for independent control of hot and cold water.
- Cold Water: Turn the right lever handle counter-clockwise to activate cold water flow.
- Hot Water: Turn the left lever handle counter-clockwise to activate hot water flow.
- Temperature Control: Adjust both handles to achieve the desired water temperature.
- Flow Control: The further the handles are turned, the greater the water flow. The faucet provides an aerated flow, which is efficient for daily tasks like hand washing and brushing teeth, meeting EPA WaterSense criteria for water conservation.
6. Maintenance
Proper care will help maintain the finish and performance of your Moen faucet.
- Cleaning the Finish: Clean the Mediterranean Bronze finish with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or polishing agents, as these can damage the finish.
- Aerator Maintenance: If water flow decreases or becomes irregular, the aerator may be clogged. Unscrew the aerator from the tip of the spout, clean any debris, and rinse thoroughly before reattaching.
- Cartridge Replacement: Over time, if leaks occur from the handles or the faucet drips, the internal cartridges may need replacement. Refer to Moen's official website or contact customer support for specific cartridge replacement instructions for model WS84667BRB.
