Product Overview
The Watts Premier OneFlow Cartridge Filter Anti-Scale System, Model OFTWH-R, is designed to condition cold tap water and provide scale protection for various water-using equipment. This system transforms dissolved hardness minerals into harmless, inactive microscopic particles, preventing scale buildup on internal and external surfaces without the use of chemicals or electricity.
It is suitable for both residential and commercial applications, including protection for water heaters, hot-beverage systems, appliances, and steamers. The OneFlow system is not a water softener and does not remove minerals from the water; instead, it utilizes environmentally friendly technology for scale prevention.

Setup and Installation
The OneFlow system is designed for installation before a water-using device and should only be installed on the cold water supply line. It features a 3/4 inch FNPT connection for integration into your plumbing system.
Installation Steps:
- Preparation: Ensure the main water supply is turned off before beginning installation.
- Mounting: Securely mount the filter unit to a wall using appropriate screws and a fixing bracket. Refer to the installation diagram for proper orientation and spacing.
- Connections: Connect the 3/4 inch FNPT inlet to the cold water supply line. Install a ball valve on the inlet side for easy isolation during maintenance. Connect the outlet to your water-using appliance.
- Leak Check: Slowly turn on the main water supply and check for any leaks at the connections.

Operating Principles
The OneFlow system operates on a unique technology that converts hardness minerals (like calcium and magnesium) into a crystalline form that does not adhere to surfaces. This process prevents scale buildup without removing beneficial minerals from the water or adding any chemicals. It requires no electricity or control valve, making it a virtually maintenance-free and environmentally friendly solution for scale prevention.
Maintenance
The Watts Premier OneFlow system is designed for minimal maintenance. The primary maintenance requirement is the replacement of the filter cartridge.
Cartridge Replacement:
- The OneFlow media cartridge should be replaced every 12 months to ensure optimal performance and continued scale protection.
- To replace the cartridge, turn off the water supply to the unit, relieve pressure, unscrew the filter housing using the provided wrench, remove the old cartridge, insert a new one, and reassemble.
Troubleshooting
If you experience issues with your OneFlow system, consider the following:
- Reduced Water Flow: Check if the cartridge is due for replacement. A clogged cartridge can restrict water flow.
- Continued Scale Buildup: Ensure the system is installed correctly on the cold water line. Verify that the cartridge is not past its recommended service life (12 months).
- Leaks: Check all connections for proper sealing. Ensure the O-rings are correctly seated and not damaged.
For persistent issues, it is recommended to consult a qualified plumbing professional or contact Watts Premier customer support.
