TOTO TET3UA31#SS – Frequently Asked Questions
1) What exactly is the TOTO TET3UA31#SS, a toilet or just the flush valve?
It is the flush valve, not a fixture. The TET3UA31#SS is a TOTO concealed electronic flush valve (EFV) for a toilet, so you still need the compatible water closet bowl, carrier and supply rough-in to complete the installation.
2) Can a concealed electronic flush valve like the TOTO TET3UA31 be retrofitted onto an existing exposed flushometer installation?
Not as a straight swap. A concealed EFV needs a wall cavity and an access provision for the valve body, plus power to the sensor, so it belongs in new construction or a wall that is already being opened. If the wall is staying closed, an exposed sensor flushometer is the type to look at instead.
3) Is the TOTO TET3UA31 flush valve concealed behind the wall or exposed?
Concealed. The valve body mounts behind the finished wall, with only the sensor plate exposed in the room, which is why it is specified on commercial restroom jobs where an exposed chrome flushometer is not wanted and where tamper resistance matters.
4) What part number do I order for the TOTO concealed toilet EFV in the stainless sensor plate finish?
Order TOTO TET3UA31#SS. The #SS suffix is the finish code that carries on the end of the model number, and it is the single configuration this valve is built in, so there is no separate handing, backset or trim choice to specify with it.
5) Will the TOTO TET3UA31 work on a urinal as well as a toilet?
No. It is built as a water closet valve, and toilet and urinal flush valves deliver different volumes, so a urinal needs a urinal-specific EFV. Using a closet valve on a urinal will overflush the fixture.
