5. Installation Guide
5.1 Before You Begin
- Ensure you have all necessary tools: adjustable wrench, screwdriver, plumber's tape.
- Turn off the main water supply to your bathroom.
- Clear the area under the sink for easy access.
5.2 Installation Steps
- Prepare the Mounting Hole: Ensure your basin or countertop has a single mounting hole with a diameter between 32mm and 43mm. The maximum countertop thickness should not exceed 42mm.
- Install the Faucet: Insert the faucet body into the mounting hole. Ensure the base gasket is properly seated to prevent leaks.
- Secure the Faucet: From underneath the sink, slide the rubber washer, metal washer, and then the fixing nut onto the threaded shank of the faucet. Tighten the fixing nut securely using the provided anti-loose fixing screws and a screwdriver.
- Connect Water Supply Hoses: Attach the hot and cold PEX hoses to the corresponding inlets on the faucet body. The hoses are typically color-coded (red for hot, blue for cold). Hand-tighten first, then use an adjustable wrench for a final snug turn, being careful not to overtighten.
- Connect to Water Supply: Connect the other ends of the PEX hoses to your hot and cold water supply lines. Use plumber's tape on the threaded connections for a watertight seal.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for any signs of leaks. If leaks are present, tighten the connections slightly until they stop.
- Flush the Faucet: Open the faucet handle to allow water to flow for a few minutes. This will flush out any debris from the new installation.

6. Operation
The Decaura Bathroom Basin Mixer Faucet features a single lever handle for controlling both water flow and temperature.
- Water Flow Control: Lift the handle upwards to increase water flow. Push the handle downwards to decrease or shut off water flow.
- Temperature Control: Move the handle to the left for hot water and to the right for cold water. Adjust the handle position between left and right to achieve your desired water temperature.

7. Maintenance and Care
Proper maintenance will ensure the longevity and continued performance of your Decaura faucet.
- Cleaning the Finish: Clean the chrome finish regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome. Avoid using abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- Aerator Cleaning: If water flow becomes restricted or uneven, the aerator may be clogged with mineral deposits. Unscrew the aerator from the end of the spout, clean any debris or mineral buildup, and rinse thoroughly before reattaching.
- Cartridge Care: The ceramic cartridge is designed for long-term durability. If you experience persistent drips or leaks from the handle, the cartridge may need inspection or replacement. Contact customer support for assistance.
8. Troubleshooting
This section addresses common issues you might encounter with your faucet.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged aerator; partially closed shut-off valve; kinked supply hose. | Clean the aerator (see Maintenance); ensure shut-off valves are fully open; check supply hoses for kinks. |
| Leaking from Spout | Worn cartridge; debris in cartridge. | Contact customer support for cartridge replacement or inspection. |
| Leaking from Base | Loose mounting nut; damaged O-ring/gasket. | Tighten the mounting nut underneath the sink; inspect and replace O-rings/gaskets if damaged. |
| Difficulty Adjusting Temperature | Cartridge issue; unbalanced water pressure. | Ensure hot and cold water supplies are fully open; contact customer support if problem persists. |
