TOTO TET2GBIA31#SS – Frequently Asked Questions
1) Is the TOTO TET2GBIA31#SS a flush valve for a toilet or for a urinal?
It's a toilet flush valve. TOTO lists the application as toilet, and it flushes at 1.6 gallons per flush, which is the water closet rate rather than a urinal rate. If you're replacing a urinal valve, you need a urinal-specific EFV instead, since a 1.6 gpf valve will over-deliver on a urinal fixture.
2) What does "concealed" mean on the TOTO TET2GBIA31 flush valve, and what does that mean for my wall?
Concealed means the valve body mounts behind the finished wall, with only the sensor plate exposed in the room. That takes a chase or a furred wall deep enough to house the valve and access for service, so it is specified at rough-in rather than swapped onto an exposed-valve installation. If your existing toilets run exposed chrome flushometers on the room side, a concealed valve is not a like-for-like replacement.
3) Will a 1.6 gpf flush valve work on a high-efficiency 1.28 gpf toilet bowl?
No. The TET2GBIA31#SS delivers 1.6 gallons per flush, and a bowl engineered for 1.28 gpf should be paired with a valve at its rated volume, otherwise you waste water and can push the trapway beyond what the bowl was tuned for. Match the valve rating to the bowl rating and order a 1.28 gpf valve for HET fixtures.
4) Is the TOTO TET2GBIA31#SS a sensor-operated valve or a manual handle?
Sensor operated. TOTO catalogues it as an IOT EFV, meaning a connected electronic flush valve, so flushing is automatic rather than by a manual lever. Plan for the electrical or battery provision the valve requires at the rough-in, not just the water supply.
5) What is the exact part number to order for the TOTO 1.6 gpf concealed toilet flush valve, and what is the #SS suffix?
Order it as TOTO TET2GBIA31#SS. The part number after the hash is the finish code, so the #SS suffix identifies the specific finish variant of the TET2GBIA31 valve. Quote the full string including #SS so the sensor plate arrives in the finish you expect.
