Toto IOT EFV CONCEALED,TOILET,1.0G TET3UBIA32#SS

It's a toilet flush valve, not a urinal valve. TOTO lists the application as toilet (water closet), and the part is a concealed electronic flush valve rated at 1.0 gallon per flush. If you're specifying a urinal in the same restroom, you need a separate urinal valve with the matching urinal flush volume.

Concealed means the valve body and control mount behind the finished wall, with only the sensor plate exposed on the room side. That requires an accessible chase or carrier space behind the fixture and access for service. If you have a finished wall with no chase and nothing roughed in behind it, an exposed flushometer is the practical choice instead.

Only if the bowl is rated for 1.0 gallon per flush. Flushometer bowls are engineered around a specific flush volume, so pairing a 1.0 gpf valve with a 1.6 gpf bowl typically leaves waste in the trapway and generates complaints. Match the valve's 1.0 gpf to the volume stamped or catalogued for the bowl before ordering.

The TET3UBIA32#SS is an electronic (sensor) valve, part of TOTO's IoT connected flush valve line, so it flushes automatically on user departure rather than by a lever. Plan for the power and control provisions any electronic flushometer needs; a manual handle is not part of this configuration.

Order it as TOTO TET3UBIA32#SS. The #SS suffix is the finish code on the exposed sensor plate, and it is the single configuration this valve is built in, so there is no separate finish or volume selection to make on the order.

It works well for that where the water closets are 1.0 gpf and the walls carry a chase for concealed valves. One caution for a multi-building rollout: concealed valves are not a drop-in swap for exposed flushometers, so any restroom currently running an exposed chrome flushometer needs wall work, not just a valve change. Verify each restroom's bowl rating and wall construction before you commit to one model across the portfolio.
