Package Contents
The Delta Faucet RP28595 package includes:
- 1 x Delta Faucet RP28595 Single-Handle Temperature Knob and Cover (Chrome)
Note: Additional tools required for installation (e.g., screwdriver) are not included.
Setup and Installation
This section outlines the steps to replace your existing Delta faucet temperature knob and cover with the RP28595 model. The handle attachment mechanism is screw-on.
- Turn Off Water Supply: Locate the main water shut-off valve for your home or the specific shut-off valves for the shower/bath faucet. Turn them off completely to prevent water flow during installation.
- Remove Old Knob/Cover: Carefully remove the existing temperature knob and cover. This typically involves prying off a decorative cap (if present) to expose a screw. Unscrew the retaining screw and pull the old knob and cover straight off the valve stem.
- Inspect Valve Stem: Ensure the valve stem is clean and free from debris. If the existing inner knob (the part the cover snaps onto) is intact and functional, you may only need to replace the outer cover. The RP28595 includes both the knob and cover.
- Install New Knob/Cover:
- Align the new RP28595 knob onto the valve stem. Ensure it seats properly.
- Secure the knob with the retaining screw. DO NOT OVERTIGHTEN the screw, as this can damage the plastic components. Tighten until snug.
- If your model includes a decorative cap, snap it into place over the screw.
- Restore Water Supply: Slowly turn the water supply back on. Check for any leaks around the newly installed knob.
- Test Functionality: Test the new temperature knob to ensure smooth operation and proper temperature adjustment.
Operating Instructions
The Delta Faucet RP28595 temperature knob allows you to control the water temperature. Rotate the knob to adjust the temperature from cold to hot. The knob is designed for ambidextrous use.
- Rotate counter-clockwise for hotter water.
- Rotate clockwise for colder water.
Maintenance
To maintain the chrome finish and ensure smooth operation of your Delta Faucet RP28595 temperature knob and cover:
- Cleaning: Clean the chrome surface regularly with a soft, damp cloth. Use mild soap and water if necessary. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Inspection: Periodically check the knob for any looseness. If it feels loose, gently tighten the retaining screw (refer to installation steps, ensuring not to overtighten).
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob is loose or wobbly. | Retaining screw is loose. | Remove decorative cap (if present) and gently tighten the retaining screw. Do not overtighten. |
| Difficulty turning the knob. | Mineral buildup or internal valve issue. | Ensure the knob is properly seated. If the issue persists, the problem may be with the internal valve cartridge, which is beyond the scope of this replacement part. Consult a plumber. |
| Water temperature not adjusting correctly. | Internal valve cartridge malfunction. | This replacement part is for the external knob and cover. If temperature control is faulty, the internal valve cartridge likely needs replacement. Consult a plumber or Delta Faucet support. |
