TOTO TET2LBIA31#SS – Frequently Asked Questions
1) Is the TOTO TET2LBIA31#SS a toilet flush valve or a urinal flush valve?
It's a toilet flush valve. TOTO lists the TET2LBIA31#SS as a concealed electronic flush valve with a toilet application and a 1.28 gallon flush, so it is not intended for urinal service, which uses much lower flush volumes.
2) Will the TOTO TET2LBIA31#SS meet a 1.28 gpf high-efficiency toilet spec?
Yes. The TET2LBIA31#SS flushes 1.28 gallons, which is the standard high-efficiency water closet volume called out on most commercial specs and required by WaterSense-based purchasing rules. Pair it with a bowl rated for 1.28 gpf so the flush volume matches the fixture.
3) Does the TOTO TET2LBIA31#SS mount in the wall or on the exposed supply?
It's a concealed valve, so the body installs behind the finished wall with only the sensor plate visible in the room. That means you need a chase or rough-in cavity behind the fixture; if the wall is solid or there is no access, an exposed flush valve is the right choice instead.
4) What is the exact TOTO part number for the IOT concealed 1.28 gpf toilet flush valve?
Order it as TOTO TET2LBIA31#SS. The #SS suffix is TOTO's finish designator, and quoting the full code with the suffix is what keeps you from getting a different trim variant in the same family.
5) Is this TOTO flush valve sensor-operated or manual handle?
The TET2LBIA31#SS is an electronic flush valve (TOTO's IOT EFV line), so flushing is sensor-initiated rather than by a manual handle. Plan on power and a sensor plate location at the fixture, not a lever-type rough-in.
