TOTO TET3UBI231#SS – Frequently Asked Questions
1) Is the TOTO TET3UBI231#SS a flush valve for a toilet or a urinal?
It's a toilet flush valve. TOTO lists the TET3UBI231#SS application as Toilet, so it should not be specified on a urinal fixture, which uses a lower-volume valve. It is a concealed IoT electronic flush valve rated at 1.0 gallon per flush.
2) What does "concealed" mean on the TOTO TET3UBI231#SS flush valve, and what does that mean for the wall?
Concealed means the valve body and electronics sit behind the finished wall, with only the sensor plate exposed in the room. That requires a chase or wall cavity at the fixture plus access for service, so it is a rough-in decision made before the wall closes up, not a drop-in swap for an exposed-pipe valve like a manual or sensor Flushometer.
3) Will a 1.0 GPF electronic flush valve work with any floor-mounted toilet bowl?
No. A flushometer-valve bowl has to be rated for the same flush volume as the valve, so this 1.0 gallon per flush unit needs a 1.0 GPF-rated flushometer bowl with a matching spud size and location. Pair it with a tank-type bowl or a 1.6 GPF bowl and you get poor bowl evacuation.
4) Which TOTO part number do I order for the concealed IoT toilet flush valve, and does it come in more than one finish?
Order TET3UBI231#SS. It's a single configuration, with #SS designating the stainless finish on the exposed sensor plate, so there is no second finish or volume choice to specify on this model. Barcode on the carton is 739268441835.
5) Is the TOTO IoT flush valve a hands-free sensor unit for high-traffic restrooms?
Yes. It's an electronic flush valve (EFV) with sensor actuation and network-connected IoT functionality, which is why it shows up in commercial and institutional restroom packages rather than residential work. Because it is electronic, the installation needs power at the valve inside the wall chase, which is a trade coordination item on the rough-in, not an afterthought.
