Hydrotek HB8-R025 Automatic Flush Valve Retrofit Kit (0.25 GPF Urinal)
The Hydrotek HB8-R025 is an ultra-high-efficiency (UHE) sensor-activated retrofit kit engineered to convert standard manual urinal valves into high-performance, touchless systems. Specifically designed to provide a "quarter-gallon" 0.25 GPF (1.0 LPF) flush, this kit allows facilities to achieve massive water savings—75% over standard 1.0 GPF valves—while upgrading to modern hygiene standards. Compatible with industry-standard manual valves from Sloan, Toto, and Zurn, this battery-operated solution is the definitive choice for LEED-certified buildings and high-traffic commercial environments seeking to reduce utility costs and maintenance overhead.
Professional-Grade Engineering & Universal Compatibility
- Seamless Universal Retrofit: The HB8-R025 is precision-engineered for a perfect mechanical fit with the most common manual urinal valve bodies in the industry, including Sloan Royal/Regal, Zurn AquaVantage/AquaFlush, and Toto models. This allows for a rapid "top-down" upgrade that maintains the existing brass plumbing while introducing advanced electronic control.
- Touchless ADA Compliance: By replacing the traditional manual handle with a sophisticated infrared sensor, this kit provides a 100% hands-free user experience. This fulfills all ADA accessibility requirements and significantly improves facility hygiene by eliminating a primary touchpoint for cross-contamination.
- Precision Piston Reliability: Hydrotek’s proprietary industrial-grade piston technology provides a significant performance advantage over traditional diaphragm systems. The piston mechanism is exceptionally resistant to mineral deposits and waterborne debris, ensuring a precise 0.25 GPF flush volume even in buildings with older infrastructure or fluctuating water pressure.
- Corrosion-Resistant Construction: Featuring a high-quality brass sensor housing with a durable chrome finish and industrial-grade VSI silicone elastomer seals, the system is built to withstand the rigorous demands of heavy public use and exposure to treated municipal water supplies.
Advanced Sensor & Battery Features
- Ultra-High-Efficiency Conservation: At just 0.25 GPF, this kit is a critical component for facilities aiming for LEED Platinum status or those located in regions with strict water conservation mandates.
- Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB8-R025 requires no electrical hardwiring. This simplifies the installation process and makes it an ideal solution for retrofitting older restrooms where running power is cost-prohibitive.
- True Mechanical Manual Override: Unlike many sensor valves that fail when power is lost, the HB8-R025 includes a standard manual-mechanical override button. This ensures the urinal remains fully operational for users at all times, even during battery maintenance cycles.
- Automated Hygiene (Sentinel) Flush: The integrated electronics include a built-in 24-hour sentinel flush feature. If the fixture is not used for a full day, the system automatically activates a flush to maintain the trap seal and prevent sewer gases from entering the restroom environment.
- Smart Self-Diagnostics: The system includes sophisticated self-diagnostic logic and a manual reset function, allowing facility maintenance staff to quickly troubleshoot and ensure consistent uptime.
