TOTO ECOPOWER Touchless Toilet Flush Valve, 1.6 GPF, Exposed, IoT-Ready, Made to Order, Valve Only, Polished Chrome - TET1GBIA#CP

The TOTO TET1GBIA#CP is an ECOPOWER touchless (sensor) flush valve for 1.6 GPF toilets with a 1-1/2" top spud inlet, exposed. 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.

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 TET1GBIA32#CP.

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. A true mechanical override still flushes it by hand.

Will it fit my toilet?

It is for a toilet with a 1-1/2" top spud inlet. 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.
