3. Important Safety Information
Always observe the following safety precautions when working with plumbing fixtures:
- Turn Off Water Supply: Before beginning any installation or maintenance, ensure the main water supply to the faucet is completely shut off.
- Wear Eye Protection: Protect your eyes from debris or splashes.
- Use Appropriate Tools: Ensure you have the correct tools for the job to prevent damage to the valve or faucet.
- Consult a Professional: If you are unsure about any step, consult a qualified plumber.
4. Setup and Installation
This section outlines the general steps for replacing a cold valve cartridge. Specific faucet models may vary, so always refer to your faucet's original installation guide if available.
4.1. Pre-Installation Check
Before installing, verify that you have the correct valve for your faucet. The GP1092203 is designed for newer Kohler widespread faucets (2011-present) that typically use a plastic-bodied valve. If your existing valve is all brass and copper, you may require the K-GP77006-RP model instead. Disassemble your faucet to confirm the existing valve type before proceeding.
4.2. Installation Steps
- Shut Off Water Supply: Locate and turn off the cold water supply valve under the sink or the main water supply to your home.
- Drain Faucet: Open the faucet handle to relieve any remaining water pressure and drain residual water.
- Remove Faucet Handle: Carefully remove the faucet handle according to your faucet model's instructions. This usually involves unscrewing a set screw or prying off a decorative cap.
- Access Valve Cartridge: Remove any retaining nuts, screws, or clips that secure the existing valve cartridge in place.
- Remove Old Valve: Gently pull out the old cold valve cartridge. Note its orientation for reference.
- Install New Valve: Insert the new KOHLER GP1092203 UltraGlide Cold Valve into the faucet body, ensuring it is correctly seated and oriented. The new UltraGlide valve can be identified by a purple paint mark on the brass stem and a black plastic nut.
- Secure Valve: Reinstall any retaining nuts, screws, or clips to secure the new valve cartridge. Do not overtighten.
- Reassemble Faucet: Reattach the faucet handle and any other components removed during disassembly.
- Restore Water Supply: Slowly turn on the cold water supply valve.
- Check for Leaks: Inspect all connections for any signs of leaks. Run the faucet for a few moments to ensure proper operation and check for drips.
5. Operating Instructions
The UltraGlide Cold Valve controls the flow of cold water to your faucet. Once installed, the valve operates in conjunction with your faucet handle. Turning the faucet handle will open or close the valve, regulating the cold water output and temperature when mixed with hot water.
6. Maintenance
The KOHLER GP1092203 UltraGlide Cold Valve is designed for minimal maintenance due to its innovative design that protects internal components from water exposure. However, regular checks can help ensure its longevity:
- Regular Inspection: Periodically check around the base of your faucet and under the sink for any signs of leaks or moisture.
- Clean Faucet Exterior: Keep the exterior of your faucet clean to prevent mineral buildup that could affect handle movement.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on your faucet, as these can damage finishes and potentially affect valve components.
7. Troubleshooting
If you encounter issues after installing your UltraGlide Cold Valve, consider the following:
- Leaks from Faucet Base:
- Ensure all connections are tight but not overtightened.
- Verify the valve is correctly seated within the faucet body.
- Check if the correct valve model (GP1092203) was installed for your faucet. An older faucet might require a different valve (e.g., K-GP77006-RP).
- Stiff Faucet Handle:
- Mineral buildup on external faucet components can cause stiffness. Clean the faucet thoroughly.
- Ensure the valve was installed correctly and is not binding.
- No Water Flow or Reduced Flow:
- Confirm the main water supply and the cold water shut-off valve under the sink are fully open.
- Check for any obstructions in the faucet aerator.
If problems persist, it is recommended to contact Kohler Customer Support or a qualified plumber.
