3. Components List
Before beginning installation, ensure all components are present and undamaged. The package should contain the following items:
- Lift Rod: The main metal rod that connects to the drain stopper mechanism.
- Knob: The decorative handle attached to the top of the lift rod for manual operation.
- Set Screw: A small screw used to secure the knob to the lift rod.
4. Installation Instructions
This replacement part is designed for easy installation, typically requiring no specialized tools. Follow these steps to replace your existing lift rod assembly:
- Preparation: If replacing an existing lift rod, carefully remove the old knob and lift rod from the faucet body. This may involve loosening a set screw on the old knob.
- Insert Lift Rod: Insert the new lift rod into the designated opening on the faucet body. Ensure the bottom end of the lift rod engages correctly with the drain stopper mechanism beneath the sink.
- Attach Knob: Place the new knob onto the top of the lift rod. Align the set screw hole on the knob with the flat surface or indentation on the lift rod, if present.
- Secure Knob: Using a small screwdriver (not included), insert and tighten the provided set screw into the knob to firmly secure it to the lift rod. Do not overtighten.
- Test Functionality: Operate the lift rod and knob to ensure the drain stopper opens and closes smoothly and completely. Adjust the lift rod's position if necessary to achieve proper drain operation.
5. Operation
The lift rod and knob assembly controls the drain stopper in your bathroom sink. To operate:
- To Close the Drain: Push the knob downwards. This action lowers the drain stopper, sealing the sink drain.
- To Open the Drain: Pull the knob upwards. This action raises the drain stopper, allowing water to flow out of the sink.
Ensure smooth movement and avoid excessive force when operating the lift rod.
6. Maintenance
Proper care and maintenance will help preserve the finish and functionality of your DELTA Faucet RP53411 lift rod assembly.
- Cleaning: Clean the chrome finish regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Inspection: Periodically check the set screw for tightness. If the knob feels loose, gently tighten the set screw.
- Lubrication: If the lift rod movement becomes stiff, a small amount of silicone-based lubricant can be applied to the pivot points of the drain stopper mechanism beneath the sink, ensuring it does not come into contact with the visible chrome finish.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob is loose or detached from the lift rod. | Set screw is loose or missing. | Tighten the set screw. If missing, contact DELTA Faucet for a replacement part. |
| Lift rod does not operate the drain stopper. | Lift rod not properly engaged with the drain stopper mechanism. | Ensure the lift rod is fully inserted and correctly connected to the pivot rod of the drain assembly beneath the sink. |
