TOTO TET3GBI433#SS – Frequently Asked Questions
1) Is the TOTO TET3GBI433#SS a flush valve for a toilet or for a urinal?
It's a toilet flush valve. TOTO's TET3GBI433#SS is a concealed electronic flush valve rated at 1.6 gallons per flush, which is the water closet flush rate rather than a urinal rate. If you're specifying a urinal fixture, you need a urinal-rated EFV instead, not this one.
2) What does "concealed" mean on the TOTO TET3GBI433 flush valve, and does that change how it gets roughed in?
Concealed means the valve body mounts behind the wall, with only the sensor and cover plate exposed in the room. That requires an accessible chase or carrier space behind the fixture and the rough-in has to be set before the wall is closed, unlike an exposed flushometer that bolts onto the supply in front of the finished wall. If your wall is already finished with no access, an exposed electronic flush valve is the easier retrofit.
3) Will the TOTO TET3GBI433#SS meet a 1.6 gpf water closet spec?
Yes. The valve is a 1.6 gallon per flush toilet unit, which matches the standard commercial water closet flush volume called out on most drawings. If the spec sheet calls for a high efficiency 1.28 gpf closet, this is the wrong flush rate and you want the 1.28 version.
4) Is TET3GBI433#SS a sensor operated flush valve or manual?
Sensor operated. It's an electronic flush valve (EFV), so flushing is automatic on user detection rather than by a handle or push button. That matters in high traffic and healthcare washrooms where touchless operation is part of the spec, and it also means the fixture needs power provided at the valve location.
5) What exact part number should I order for the TOTO concealed toilet EFV in stainless?
Order TET3GBI433#SS. The #SS suffix is TOTO's finish code carried on the part number, and it's the single configuration this model is built in, so there's no separate finish or size to specify when you place the order.
6) I'm standardizing restroom flush valves across a facility. Can I use this same TOTO EFV on every water closet?
For 1.6 gpf water closets with a concealed rough-in, yes, one part number covers them all since TET3GBI433#SS is offered in a single configuration. Where the building mixes in urinals or 1.28 gpf closets, or has fixtures plumbed for an exposed flushometer, those openings need a different valve, so walk the restrooms and count by rough-in type before you commit to a single SKU.
