The TOTO TET2GBi#SS is an ECOPOWER touchless (sensor) flush valve for 1.6 GPF toilets, concealed behind a 14" x 12" stainless steel cover plate. This is the valve only: the vacuum breaker and angle stop set is sold separately. Its water-driven turbine recharges the power supply during use, so the valve is self-powered with no minimum daily usage requirement. It is IoT-ready; the IoT communication card is sold separately.
The water-powered turbine in the EcoPower flush valve charges the power supply during usage and provides maximum performance in even the most demanding, high-traffic commercial spaces.

Common Questions
- Is this the valve only, or does it include the vacuum breaker?
- Valve only. It will not connect to the fixture without a vacuum breaker and angle stop set, sold separately. The complete version with the vacuum breaker set is TET2GBi31#SS or TET2GBi32#SS.
- Does it need electrical power?
- No outside power: TOTO builds it as a self-powered hydroelectric system. Water flowing through the valve turns a turbine that recharges the power supply, and there is no minimum daily usage requirement.
- Will it fit my toilet?
- It serves a toilet with a 1-1/2" spud. As a concealed valve only, it pairs with either a top spud or a back spud vacuum breaker set; choose the set that matches the bowl. Pair it with a toilet bowl rated for 1.6 GPF.
- Can it be installed in California and other high-efficiency states?
- No. TOTO's 2026 Price Book states this 1.6 GPF model cannot be installed in CA, CO, GA, MA, NJ, NY, TX and WA due to high-efficiency requirements.
