TOTO® ECOPOWER® 1.6 GPF Toilet Flushometer Valve is ideal for high-traffic 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 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 ADA compliant. This flushometer valve is for use with toilets that have a 1-1/2 inch top spud inlet using 12 inch vacuum breaker tubes. Included: 1 inch angle stop, 12 inch vacuum breaker set, spud nut and escutcheon to connect to the toilet spud, and sweat solder kit. TOTO TET1GB32 Features: Covered under TOTO's 3 year limited warranty and 3 year commercial warranty Coordinates with products from the ECO POWER line seamlessly Constructed of bronze 1-1/2" top mounted spud placement Valve utilizes an electronic sensor that automatically flushes when activated All hardware required for installation is included TOTO TET1GB32 Technologies / Benefits: EcoPower: TOTO was the first manufacturer to introduce electronic sensor faucets to the US market. These faucets only operate when the sensor detects the presence of hands and quickly shut off when not needed. Further, TOTO has innovated the use of water as a power source by designing sensor flush valves and faucets, under the trade name EcoPower, that use the kinetic energy of flowing water to power their electronics, greatly reducing maintenance and eliminating battery disposal, which helps to protect the environment.
