The faucet is equipped with a 360-degree swinging spout. This allows you to direct the water flow as needed, providing flexibility for various tasks in your sink or utility tub.
5.3 Hose Attachment
The spout includes a hose thread for easy attachment of a standard hose, if required for specific tasks.
6. Maintenance
6.1 Cleaning
To maintain the chrome finish of your faucet, clean regularly with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
6.2 Aerator Cleaning
If water flow decreases, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris, and rinse thoroughly before reattaching.
7. Troubleshooting

| Low Water Flow | Clogged aerator; partially closed shut-off valve. | Clean aerator; ensure shut-off valves are fully open. |
