3. Product Overview
The Gerber 163079 92-298 is a single handle ceramic disc cartridge designed for precise control of water flow and temperature in compatible Gerber faucets. It features a durable ceramic disc mechanism for smooth operation and a long lifespan, and includes a limit stop for temperature regulation.
Key Components:
- Ceramic Discs: Two highly polished ceramic discs that slide against each other to control water flow and mix hot and cold water.
- Housing: The main body of the cartridge, typically made of durable plastic.
- O-Rings/Seals: Rubber rings that create a watertight seal within the faucet body.
- Stem: The part that connects to the faucet handle, allowing for movement and control.
- Limit Stop: An adjustable component that restricts the maximum hot water temperature to prevent scalding.
4. Installation Instructions
This cartridge is a direct replacement for Gerber Single Lever "Hardwater" Kitchen and Lavatory Faucets (models 73-2401, 73-3409, 73-3410). It can also replace older 92-258 cartridges with minor adjustments.
Tools Required: Adjustable wrench, screwdriver (flathead and/or Phillips, depending on faucet model), pliers, penetrating oil (optional), clean cloth.
- Shut off Water Supply: Locate the hot and cold water supply valves under the sink and turn them off completely. Turn on the faucet to drain any remaining water and relieve pressure.
- Remove Faucet Handle: Depending on your faucet model, you may need to pry off a decorative cap to access a screw. Use a screwdriver to remove the screw and then pull the handle straight up to remove it.
- Remove Retaining Nut/Cap: Carefully remove any decorative escutcheon or retaining nut that secures the cartridge in place. An adjustable wrench or pliers may be needed.
- Extract Old Cartridge: Gently pull the old cartridge straight out of the faucet body. If it is stuck, try wiggling it slightly or using pliers. Avoid excessive force. Note its orientation for reference.
- Clean Faucet Body: Clean any mineral deposits or debris from the faucet body opening where the cartridge sits. A clean cloth or soft brush can be used.
- Install New Cartridge: Insert the new Gerber 163079 92-298 cartridge into the faucet body, ensuring it is correctly oriented. The tabs or notches on the cartridge should align with the corresponding slots in the faucet body. Ensure the O-rings are properly seated.
- Secure Cartridge: Reinstall the retaining nut or cap, tightening it securely but without overtightening.
- Reattach Handle: Place the faucet handle back onto the cartridge stem and secure it with the screw. Replace any decorative caps.
- Restore Water Supply: Slowly turn on the hot and cold water supply valves. Check for leaks around the faucet base and connections.
- Test Faucet: Operate the faucet handle through its full range of motion (hot, cold, mixed, on, off) to ensure proper function and check for any drips or leaks.
Note for 92-258 Replacement: If replacing an older 92-258 cartridge, you may need to use the limiting ring provided with the new 92-298 cartridge and remove the original limiting disc with a tab from the old assembly. Ensure proper alignment for optimal performance.
5. Operating Instructions
Once installed, the Gerber 163079 92-298 ceramic disc cartridge operates seamlessly with your single handle faucet. Move the handle to control both water flow and temperature:
- Water Flow: Lift the handle to increase water flow and push it down to decrease or stop the flow.
- Temperature Control: Move the handle left for hotter water and right for colder water. The ceramic discs precisely mix hot and cold water to achieve the desired temperature.
- Limit Stop Adjustment: If your faucet has an adjustable limit stop, you can set the maximum hot water temperature to prevent accidental scalding. Refer to your specific faucet's manual for instructions on adjusting the limit stop.
6. Maintenance
The ceramic disc cartridge is designed for minimal maintenance. However, following these guidelines can extend its life and ensure optimal performance:
- Regular Cleaning: Periodically clean the faucet exterior with a soft cloth and mild soap. Avoid abrasive cleaners that can damage finishes.
- Check for Leaks: Regularly inspect the faucet for any signs of dripping or leaks. Addressing minor issues promptly can prevent larger problems.
- Water Quality: In areas with hard water, mineral deposits can accumulate over time. If flow issues or stiffness occur, the cartridge may need to be removed and cleaned, or replaced if heavily scaled.
- Avoid Overtightening: When reassembling faucet components, tighten nuts and screws firmly but avoid overtightening, which can damage seals or plastic parts.
