TOTO ECOPOWER Touchless Toilet Flush Valve, 1.6 GPF, Concealed with 14" x 12" Cover Plate, IoT with LoRa Card, Made to Order, with 1-1/2" Top Spud Vacuum Breaker Set, Stainless Steel - TET2GBI432#SS

The TOTO TET2GBI432#SS is an ECOPOWER touchless (sensor) flush valve for 1.6 GPF toilets with a 1-1/2" top spud inlet, concealed behind a 14" x 12" stainless steel cover plate. It ships complete with TOTO's 1" angle stop and 1-1/2" vacuum breaker set (VB0932R#RB). Its water-driven turbine recharges the power supply during use, so the valve is self-powered with no minimum daily usage requirement. It includes the long-range (LoRa) IoT communication card.

Common Questions

Is this the valve only, or does it include the vacuum breaker?

It is complete: the valve ships with TOTO's 1-1/2" vacuum breaker set (VB0932R#RB) for a top spud toilet.

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 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.
