TOTO TEU3LAI421#SS – Frequently Asked Questions
1) Is the TOTO TEU3LAI421#SS a urinal flush valve or a water closet flush valve?
It's a urinal flush valve. The TEU3LAI421#SS is TOTO's concealed electronic flush valve (EFV) for urinals, rated at 0.5 gallons per flush. If you're flushing a floor-mount or wall-hung toilet, this is the wrong part, you need a water closet EFV with a 1.0 or 1.28 gpf rating instead.
2) Is the TOTO TEU3LAI421#SS concealed or exposed mounting?
Concealed. The valve body mounts behind the finished wall, with only the sensor plate exposed, so you need a chase or wall cavity behind the urinal and access for service. If your urinals are set against a solid wall with no chase, an exposed EFV is the configuration to order instead.
3) Will a 0.5 gpf flush valve work on any urinal fixture?
Only on a urinal rated for 0.5 gallons per flush or higher-efficiency. Fixture and valve flush volume have to match, so pairing this 0.5 gpf valve with a 1.0 gpf urinal bowl will under-flush the trapway. Check the gpf stamped on the fixture before you pair it.
4) What does the IOT designation on the TOTO TEU3LAI421 urinal valve mean for a facility manager?
IOT means it's a connected electronic flush valve, so it reports and is managed over a network rather than being adjusted only at the sensor. For a facility standardizing restrooms across a campus, that's the difference between walking every fixture and monitoring them centrally. Mechanically it's still a sensor-operated concealed urinal valve at 0.5 gpf.
5) Does #SS on the TOTO TEU3LAI421 refer to the finish?
Yes, the #SS suffix is the finish code on the trim, and TEU3LAI421#SS is the complete manufacturer part number to order by. Quote the full number including the suffix, since the same valve is built in other trim codes.
