TOTO® ECOPOWER® 1.0 GPF Urinal Flushometer Valveis ideal for high-traffic commercial spaces, providing an elegant water conservation solution. Engineered to require no electricity or routine battery replacement, the ECOPOWER Flushometer Valve saves energy and water while providing maximum performance in even the most demanding commercial spaces. Powered by the force of running water, ECOPOWER hydro-turbines create an electrical current that is stored in rechargeable cells to power the sensor of the valve. The ECOPOWER flush valve is highly efficient, replenishing power stores with no minimum daily usage. No external power source or battery replacement is necessary. Ensuring that water flows only when needed, the self-adjusting ECOPOWER sensor eliminates ghost flushing that wastes water. A minimum of six seconds in front of the sensor is required to get its acknowledgement, preventing excessive flushing. A mechanical manual override flush button is present when needed. The piston and solenoid mechanism, a marked improvement over traditional rubber diaphragm type valves, maintains consistent flush volume under a range of supply pressures. The valve is WaterSense® certified and CA Title 20 and CalGreen compliant. The valve is also ADA compliant. Includes flushometer valve for urinals. Purchased separately: angle stop, vacuum breaker set, spud nut and escutcheon to connect to the urinal spud, and sweat solder kit.
