4. Setup (Installation)
Follow these steps to install your new Proplus H21 faucet handles:
- Turn Off Water Supply: Locate the water shut-off valves under the sink for both hot and cold water lines, and turn them off completely. If individual valves are not present, turn off the main water supply to your home.
- Remove Old Handles: Depending on your Delta faucet model, you may need to pry off a decorative cap to expose a screw. Use a screwdriver to loosen and remove the screw, then pull the old handle straight up and off the faucet stem. Repeat for both handles.
- Clean Faucet Area: Clean any mineral deposits or debris from the faucet base and stems.
- Install New Handles: Place the new Proplus H21 handles onto the corresponding hot and cold faucet stems. Ensure the handles are oriented correctly (e.g., 'H' for hot, 'C' for cold).
- Secure Handles: Insert the screws into the handles and tighten them securely with a screwdriver. Do not overtighten, as this can damage the handles. If applicable, replace any decorative caps.
- Restore Water Supply: Slowly turn the hot and cold water supply valves back on.
- Check for Leaks: Turn on the faucet and check for any leaks around the base of the handles or connections. If leaks occur, turn off the water supply and re-check the handle installation and connections.
5. Operating Instructions
To operate your faucet with the new Proplus H21 handles:
- Turning On/Off: Rotate the handle counter-clockwise to turn on the water and clockwise to turn it off.
- Adjusting Temperature: Use the handle marked 'H' for hot water and 'C' for cold water. Adjust the desired water temperature by mixing hot and cold water to your preference.
6. Maintenance
To ensure the longevity and appearance of your Proplus H21 faucet handles:
- Cleaning: Clean the handles regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can scratch or damage the acrylic and chrome finish.
- Tightening: Periodically check the handles for looseness. If a handle feels loose, gently tighten the retaining screw (under the decorative cap, if applicable) with a screwdriver. Do not overtighten.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Handle is loose | Retaining screw is loose. | Remove decorative cap (if present) and tighten the screw. Do not overtighten. |
| Water leaks from handle base | Improper installation or worn O-rings/gaskets (not part of handle assembly). | Ensure handle is properly seated and screw is tightened. If leak persists, the issue may be with internal faucet components (e.g., valve stem, O-rings) which are separate from the handle and may require professional plumbing service. |
| Handle does not turn smoothly | Mineral buildup or internal faucet issue. | Clean around the handle base. If the issue persists, it likely indicates a problem with the faucet's internal valve mechanism, not the handle itself. |
