The award-winning HydroClean toilet fill valve solves the two biggest reasons for water loss in toilets - miscalibration and leaks. Ordinary fill valves send water to the bowl throughout the entire tank-filling cycle. The HydroClean can be calibrated to adjust the exact amount of water needed. It also detects leaks and signals when a leak it found. Proven in independent studies to reduce water usage by 36%, the feature-rich HydroClean cleans the tank, fits all standard toilets and installs easily without tools.
