Operation
The Kohler 13690-CP Rainhead provides a single-function spray pattern designed to simulate a natural rain shower. It incorporates Katalyst air-induction technology to enhance the showering experience.
Katalyst Air-Induction Technology:
This innovative technology infuses 2.2 liters of air per minute into the water stream. This process creates larger, more luxurious water droplets that retain heat longer, providing a powerful and thoroughly drenching overhead shower experience while maintaining a 2.5 GPM flow rate.

This diagram illustrates the Katalyst Air-Induction Technology. Air is infused into the water stream, creating larger, warmer water droplets for a more drenching shower experience. The technology delivers 2.5 gallons of water per minute.

This image highlights the benefits of Katalyst Air-Induction Technology: Big Drops for a luxurious feel, Powerful and Consistent Spray due to Racetrack waterway design, Conservation by optimizing each drop, and Warmth of Water with larger drops retaining heat longer.

This diagram explains Racetrack Technology, which ensures optimal coverage and consistent spray performance by delivering the right amount of force. When combined with Air-Induction Technology, it provides a luxurious shower experience.
Maintenance
To maintain the polished chrome finish and ensure optimal performance of your rainhead, follow these cleaning guidelines:
- Regular Cleaning: Clean the rainhead regularly with a soft, damp cloth and a mild soap.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, or chemicals containing ammonia, bleach, or alcohol, as these can damage the finish.
- Mineral Deposits: If mineral deposits accumulate on the nozzles, gently rub them with your finger or a soft brush to dislodge them. For stubborn deposits, a solution of white vinegar and water can be used, followed by rinsing thoroughly.
- Drying: After cleaning, dry the rainhead with a soft cloth to prevent water spots.
Troubleshooting
If you encounter issues with your rainhead, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged nozzles or mineral buildup. | Clean the nozzles by gently rubbing them. If necessary, soak the rainhead in a vinegar solution. Check water pressure from the main supply. |
| Leaking from Rainhead | Loose connections or damaged seals. | Ensure all connections are tightened. Inspect and replace any worn or damaged gaskets or O-rings. |
| Inconsistent Spray Pattern | Partial nozzle blockage. | Clean all nozzles thoroughly to ensure even water distribution. |
