TOTO TET3LBI4#SS – Frequently Asked Questions
1) Is the TOTO TET3LBI4#SS a urinal flush valve or a toilet flush valve?
It's a toilet flush valve, not a urinal valve. The TET3LBI4#SS is TOTO's concealed IoT electronic flush valve set for water closets at 1.28 gallons per flush. If you're outfitting urinals on the same project, you need a urinal-specific EFV instead, since the flush volume and valve internals differ.
2) Does the TOTO TET3LBI4 flush valve mount exposed on the wall or behind it?
Behind it. This is the concealed version, so the valve body sits inside the wall or chase and only the sensor plate and spud connection are visible in the room. That means you need an accessible chase or carrier space behind the fixture. If the wall can't be opened up, an exposed-mount electronic flush valve is the right call instead.
3) Will a 1.28 gpf electronic flush valve work with my existing toilet bowl?
Only if the bowl is rated for 1.28 gallons per flush. The TET3LBI4#SS delivers 1.28 gpf, and pairing it with an older 3.5 gpf or 1.6 gpf flushometer bowl can leave the trapway under-scoured and cause drain-line carry complaints. Match the valve's flush volume to the bowl's rated volume, which is usually stamped or printed inside the bowl rim.
4) What does the IoT part of this TOTO flush valve actually do for a facility?
The IoT designation means the valve is a connected electronic flush valve rather than a standalone sensor valve, so it's aimed at buildings that want restroom fixtures reporting back centrally instead of being checked door to door. For a facility manager standardizing restrooms, that's the reason to pick this over a plain battery sensor valve: the flushing itself is the same hands-free 1.28 gpf operation.
5) Is TET3LBI4#SS a complete valve or just a repair part?
TET3LBI4#SS is the complete concealed electronic flush valve assembly for a 1.28 gpf toilet, ordered as a single part number. It isn't a rebuild kit or a diaphragm, so if you're only chasing a leaking or short-cycling valve, a repair kit for the valve already in the wall is the cheaper fix.
6) Does the #SS suffix on TET3LBI4 mean anything I need to specify when ordering?
The #SS is TOTO's finish code carried in the part number, so TET3LBI4#SS is the ordering designation on its own, with no separate finish selection to make. Quote and order it exactly as TET3LBI4#SS so the right trim arrives with the valve.
