Dual-Flush Water Efficiency

The Hydrotek H8CB-128DF-WBDC incorporates intelligent dual-flush technology, allowing facilities to optimize water usage depending on restroom demand. The valve offers two flush volumes:

• 1.28 GPF full flush for solid waste removal
• 1.0 GPF reduced flush for liquid waste

This system helps significantly reduce water consumption while maintaining effective flushing performance. In high-use commercial facilities, the reduced flush volume can generate substantial long-term water savings, helping building owners lower utility costs while supporting sustainability goals and water conservation programs.

Touchless Sensor Activation

The flush valve utilizes infrared sensor technology to automatically detect user presence and trigger the flush cycle after the user leaves the fixture area. This hands-free operation eliminates the need for manual flush handles, helping reduce contact points in public restrooms and improving sanitation.

Touchless flush systems are widely specified in commercial restroom design because they enhance hygiene, reduce the spread of germs, and provide a convenient, modern user experience.

AC Power with DC Battery Backup

The hardwired AC-powered system ensures reliable operation without the need for routine battery replacement. To further enhance system reliability, the H8CB-128DF-WBDC includes DC battery backup, allowing the flush valve to continue operating during electrical outages.

This dual-power configuration ensures uninterrupted restroom functionality in facilities where continuous fixture operation is critical.

Concealed Wall Box Installation

The integrated wall box design conceals the flush valve’s electronic control components within the wall, creating a streamlined restroom appearance while protecting internal parts from vandalism or tampering.

Benefits of the wall box installation include:

• Clean, modern restroom aesthetics
• Increased protection for electronic components
• Reduced exposed plumbing hardware
• Simplified restroom cleaning and maintenance

Concealed flush valve systems are frequently specified in institutional, healthcare, and premium commercial restroom projects where both durability and appearance are important.

Back Spud Fixture Compatibility

The Hydrotek H8CB-128DF-WBDC is designed for back spud water closet installations, making it compatible with many commercial toilet fixtures commonly used in institutional and public restroom settings.

Installation specifications include:

• 1" stop connection
• 1-1/2" back spud closet connection

This configuration allows for easy integration into both new construction projects and restroom renovation upgrades.
