5. Troubleshooting
If you encounter issues with your faucet, refer to the following common problems and solutions:
5.1. Low Water Pressure
- Issue: Reduced water flow from the spout.
- Possible Cause 1: Over-tightened water supply lines. The rubber gasket at the end of the supply line that connects to your water shutoff valve can become distorted and block water flow if over-tightened.
- Solution 1: Disconnect the supply lines from the shutoff valves. Inspect the rubber gaskets for distortion. Reconnect the lines, tightening them only until snug to ensure a proper seal without compressing the gasket excessively.
- Possible Cause 2: Compressed rubber ring inside the faucet body. Over time, an internal rubber ring can compress, restricting water flow.
- Solution 2: Consult the detailed installation diagram or contact customer support for guidance on accessing and inspecting internal components. Removing this ring may resolve the issue but could affect the faucet's design or warranty.
5.2. Leaks Around Handle or Base
- Issue: Water leaking from around the faucet handle or base.
- Possible Cause: Loose connections or worn internal seals.
- Solution: Ensure all connections, especially the mounting nut beneath the counter, are securely tightened. If the leak persists, internal seals or cartridges may need inspection or replacement. Contact customer support for assistance.
