The ARCORA Shower Faucet Set features a single handle for temperature and flow control, and a diverter on the tub spout to switch between tub and shower functions.
6.1 Water Flow and Temperature Control
- Turn the single handle to adjust water temperature from cold to hot. The pressure balance valve maintains consistent water pressure to prevent sudden temperature fluctuations.
- Move the handle up or down to control the water flow rate.
6.2 Showerhead Spray Settings
The 6-inch rain showerhead offers 5 spray settings. Rotate the showerhead face or a designated selector to switch between modes:
- Rain
- Pulsating Massage
- SPA Massage
- Rain + Pulsating Massage
- Rain + SPA Massage

6.3 Tub Spout Diverter

- To activate the showerhead, pull the diverter knob on the tub spout "up".
7. Maintenance
Proper maintenance will ensure the longevity and optimal performance of your ARCORA Shower Faucet Set.
7.1 Cleaning
- Clean the faucet and showerhead regularly with a soft cloth and mild soap.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the matte black finish.
- The showerhead features self-cleaning silicone nozzles. Gently rub the nozzles to remove any mineral buildup.
7.2 Valve Cartridge Care
The pressure balance valve cartridge is designed for durability. If you experience issues with temperature control or flow, the cartridge may need inspection or replacement. Refer to the troubleshooting section or contact customer support.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks from connections | Loose connections, insufficient plumber's tape. | Tighten connections. Reapply plumber's tape if necessary. |
| Low water pressure | Partially closed main water supply, clogged showerhead nozzles. | Ensure main water supply is fully open. Clean showerhead nozzles by gently rubbing them. |
| Water temperature fluctuates | Issue with pressure balance valve cartridge. | Inspect or replace the pressure balance valve cartridge. Ensure proper installation. |
| Tub spout drips after turning off | Standard feature of pressure-balancing valves. | This is normal. It releases leftover water to protect the internal mechanism and only lasts a few seconds. |
| Shower and tub run simultaneously | Valve installed too low. | Recommended valve height is 43 5/16" - 48" (1100mm - 1219mm) from the floor. Incorrect height can cause both outlets to run. |
