TOTO TET3UBI433#SS – Frequently Asked Questions
1) Is the TOTO TET3UBI433#SS flush valve for a toilet or a urinal?
Toilet. The TET3UBI433#SS is a concealed electronic flush valve set up for water closet service at 1.0 gallon per flush, not for urinal service. Urinals run much lower flush volumes, so if the fixture on the wall is a urinal this is the wrong valve.
2) Will the TOTO TET3UBI433#SS work on a 1.28 gpf or 1.6 gpf toilet?
This valve flushes at 1.0 gallon, so it is matched to a 1.0 gpf water closet. Putting it on a bowl designed for 1.28 or 1.6 gallons gives you less water than the fixture was engineered for and can leave bowl clearing short. Match the valve volume to the bowl rating stamped on the fixture.
3) Can I swap a manual handle flushometer for the TOTO TET3UBI433#SS?
Not as a straight trade. A manual flushometer is exposed and lever actuated; this is a concealed sensor-operated valve that needs a wall chase for the body and power to the electronics. Going from a manual handle to this valve is a wall and electrical job, not a trim change. If the wall has to stay closed, stay with an exposed valve.
4) Does a concealed electronic flush valve need an access panel behind the wall?
Yes. Concealed means the valve body and controls sit inside the wall chase with only the sensor plate exposed, so you need a wall opening or access panel to reach the valve for service and to make the water and power connections. Plan that access before the wall is closed up.
5) What is the exact TOTO part number for this 1.0 gpf concealed toilet flush valve?
Order it as TOTO TET3UBI433#SS. The #SS suffix is TOTO's finish code on the exposed trim, and it is the number to quote when standardizing restroom valves across a facility so later replacements match what is already installed.
