TOTO TET2UBI431#SS – Frequently Asked Questions
1) Is TOTO TET2UBI431#SS a flush valve for a toilet or for a urinal?
TET2UBI431#SS is a toilet flush valve, not a urinal valve. It is TOTO's concealed electronic flush valve rated at 1.0 gallon per flush, so it is matched to water closets specified at a 1.0 gpf flush volume. Putting it on a urinal fixture would overshoot the urinal's rated flush volume.
2) Will the TOTO TET2UBI431#SS work on a toilet rated at 1.28 or 1.6 gpf?
No. This TOTO concealed electronic flush valve delivers 1.0 gallon per flush, so it should be paired with a bowl designed to clear at 1.0 gpf. A 1.28 or 1.6 gpf bowl relies on the higher volume for carry and bowl wash, and under-flushing it leads to callbacks. For those fixtures, order the flush valve at the flush volume printed on the bowl.
3) What does "concealed" mean on the TOTO TET2UBI431#SS flush valve, and what does that mean for my rough-in?
Concealed means the valve body mounts behind the wall, inside the chase, with only the sensor or actuator plate exposed on the finished face. That requires access to the chase during rough-in and a serviceable access point afterward, which is why these are specified on commercial washrooms with a pipe chase rather than retrofitted into a solid wall. An exposed flush valve is the alternative when there is no chase to work in.
4) Why would a facility spec a sensor-operated concealed toilet flush valve instead of a manual handle?
Two reasons drive it in high-traffic restrooms: no-touch operation and a fixed, metered flush volume, in this case 1.0 gallon. For airports, schools, healthcare and stadium washrooms, that removes the hand contact point and the vandalized handle, and the concealed body puts the working parts behind the wall where they are out of reach. A manual valve is simpler to service and cheaper to stock across a small building.
5) What is the exact TOTO part number to order for the IoT EFV concealed 1.0 gpf toilet flush valve?
Order it as TET2UBI431#SS. The suffix after the hash is TOTO's finish code, so the full designation including #SS is what identifies the item on a purchase order. Quoting only TET2UBI431 can bring back a different finish.
