Maintenance
Cleaning the Finish

- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Wipe dry after cleaning to prevent water spots.
Cleaning Shower Head Nozzles
- The shower head and handheld wand feature press-to-clean silicone nozzles.
- Periodically rub the silicone nozzles with your finger or a soft brush to dislodge mineral buildup and maintain optimal spray performance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Pressure | Clogged nozzles, partially closed shut-off valve, low household water pressure. | Clean shower head nozzles. Ensure shut-off valves are fully open. Consult a plumber if household pressure is consistently low. |
| Water Leaks from Connections | Loose connections, worn O-rings/gaskets, insufficient plumber's tape. | Tighten connections. Replace O-rings/gaskets if damaged. Reapply plumber's tape. |
| Inconsistent Water Temperature | Pressure balance valve issue, hot/cold water supply problems. | Ensure hot and cold water supplies are functioning correctly. If the issue persists, the pressure balance cartridge may need inspection or replacement by a professional. |
| Diverter Not Switching Properly | Debris in diverter, worn diverter cartridge. | Flush the system. If the problem continues, the diverter cartridge may need to be replaced. |
