Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your GROHE 46173SD0 Stainless Steel Kitchen Faucet Spray Head Replacement Part. Please read these instructions carefully before proceeding with installation or use to ensure proper function and longevity of the product.
Setup and Installation
The GROHE 46173SD0 is designed for straightforward replacement of an existing kitchen faucet spray head. Follow these steps for proper installation:
- Prepare the Work Area: Ensure the water supply to the faucet is turned off before beginning. Clear any items from under the sink to access the faucet hose connection.
- Remove the Old Spray Head: Carefully unscrew the old spray head from the end of the pull-down hose. Turn counter-clockwise until it detaches.
- Inspect the Hose Connection: Examine the end of the faucet hose for the presence and condition of an O-ring. A properly seated O-ring is crucial for a watertight seal. If the existing O-ring is damaged, worn, or missing, it is recommended to replace it with a suitable part (e.g., GROHE 01224000 Spring O-Ring) to prevent leaks.
- Attach the New Spray Head: Align the threads of the GROHE 46173SD0 replacement spray head with the threads on the faucet hose. Screw the new spray head onto the hose by turning clockwise. Hand-tighten firmly. Avoid over-tightening, which can damage the threads or internal components.
- Test for Leaks: Slowly turn the water supply back on. Check the connection point between the spray head and the hose for any signs of leakage. If leaks occur, gently tighten the spray head further or re-inspect the O-ring.

Operating Instructions
The GROHE 46173SD0 spray head features a pull-down design for enhanced functionality in your kitchen. It provides a flow rate of 2.2 gallons per minute (gpm).
- Water Flow Activation: Use your faucet's handle to turn the water on and off and to adjust temperature and flow intensity.
- Spray Pattern Selection: This spray head typically offers multiple spray patterns. Press the button or switch located on the spray head to toggle between the aerated stream and the spray function.
- Pull-Down Function: Gently pull the spray head down from the faucet spout to extend the hose for greater reach and flexibility during use. After use, guide the spray head back into its docking position.
Maintenance
Regular maintenance will help preserve the appearance and functionality of your GROHE spray head.
- Cleaning: Clean the stainless steel finish regularly with a soft cloth and mild soap and water. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish. For hard water spots, use a solution of equal parts white vinegar and water, applied with a soft cloth, then rinse thoroughly.
- Nozzle Cleaning: Over time, mineral deposits can accumulate in the spray nozzles, affecting water flow. Gently rub the rubber nozzles with your finger or a soft brush to dislodge any deposits. For stubborn clogs, a toothpick can be used carefully.
- Hose Inspection: Periodically inspect the pull-down hose for any signs of wear, kinks, or damage. Ensure it retracts smoothly.
Troubleshooting
If you encounter issues with your spray head, refer to the following common troubleshooting steps:
- Leakage at Hose Connection: If water leaks from where the spray head connects to the hose, ensure the spray head is securely hand-tightened. Inspect the O-ring at the connection point. A worn or improperly seated O-ring is a common cause of leaks and may require replacement.
- Reduced Water Flow: If the water flow is weaker than usual, check the spray nozzles for mineral buildup or debris. Clean the nozzles as described in the Maintenance section. Also, ensure the main water supply to the faucet is fully open.
- Difficulty Switching Spray Patterns: If the button or switch for changing spray patterns feels stiff or unresponsive, gently clean around the button to remove any debris or mineral deposits. Avoid forcing the mechanism.
