TOTO TET3UBI431#SS – Frequently Asked Questions
1) What is the TOTO TET3UBI431#SS, a toilet or just the flush valve?
It's the flush valve, not a fixture. TET3UBI431#SS is a TOTO concealed electronic flush valve for a toilet, rated at 1.0 gallon per flush. You mount it behind the wall and pair it with a compatible wall-hung or floor-mount bowl and a carrier; the bowl is ordered separately.
2) Will a 1.0 GPF concealed flush valve work with any toilet bowl?
No. A flush valve and bowl have to be matched on flush volume. The TET3UBI431#SS delivers 1.0 gallon per flush, so it needs a bowl engineered for 1.0 gpf. Put it on a 1.6 gpf bowl and you'll get carry problems and callbacks, which is the last thing you want in a high-traffic restroom.
3) Does the TOTO TET3UBI431#SS need a chase or wall cavity behind the fixture?
Yes. It's a concealed valve, so the body and its electronics sit inside the wall with only the sensor plate exposed. You need a chase or furred wall deep enough to take it, plus access for service. If your wall is solid block with no cavity, you want an exposed flush valve instead.
4) Is this a manual flush valve or a sensor flush valve?
Sensor operated. TOTO's TET3UBI431#SS is an IoT EFV, meaning electronic flush valve with network connectivity, so it flushes hands-free and reports back rather than being pushed by a handle. If your spec calls for a simple manual handle valve, this is not that part.
5) Why would a facility choose an IoT flush valve over a standard sensor valve?
The connectivity is the point. TOTO's IoT electronic flush valve reports usage and status over a network, so a facilities team can track fixture activity and service needs across a restroom group from one place instead of walking every stall. For airports, stadiums, and large campuses that's the argument; for a small two-fixture restroom a plain sensor valve does the same flushing job.
6) What model number do I give my supplier for the TOTO concealed IoT toilet flush valve?
Order it as TET3UBI431#SS. The #SS suffix is TOTO's finish code carried on the part number, so quote the number complete with the suffix or you may get a different trim finish than the rest of the restroom.
7) Can I use this flush valve on a urinal?
No. TET3UBI431#SS is built for toilet service at 1.0 gpf. Urinals run at far lower volumes and need a urinal-specific electronic valve, so ordering this one for a urinal stall means sending it back.
8) I'm replacing a tank-type toilet. Can I drop in this TOTO concealed flush valve?
Not directly. A concealed electronic flush valve runs off a flushometer-style supply, not a gravity tank, so the opening needs the right supply line size and pressure plus in-wall space and power provisions. Swapping from a residential tank toilet means re-piping and opening the wall, which is a different scope than a fixture change.
