TOTO THP3281R – Frequently Asked Questions

1) What is the TOTO THP3281R and what does it do?
THP3281R is a TOTO replacement valve assembly for an exposed toilet flush valve, rated at 1.0 gallon per flush. It is a service part for the flushometer, not a complete fixture, so you order it when the valve on an existing exposed toilet installation needs to be rebuilt or replaced rather than when you need a new bowl.
2) Will the THP3281R valve assembly work on a 1.28 or 1.6 gpf toilet?
No. The THP3281R assembly is a 1.0 gallon per flush valve, so it will meter 1.0 gallon regardless of the bowl it is mounted on. Putting it on a bowl designed for 1.28 or 1.6 gpf under-flushes the fixture. Match the valve's flush volume to the bowl's rated volume and order the assembly that matches instead.
3) Is the THP3281R for an exposed flush valve or a concealed one?
Exposed. The assembly is specified for an exposed toilet flush valve, the kind where the valve body and supply are visible above the bowl in a commercial restroom. Concealed, behind-the-wall valve installations take a different part.
4) What part number do I give my supplier for the TOTO exposed toilet 1.0 gpf valve assembly?
Order it as TOTO THP3281R. That is the manufacturer part number for the 1.0 gpf exposed toilet valve assembly, and it is the number a distributor or facilities purchasing group should put on the requisition.
5) Does the THP3281R come as a complete assembly or do I have to buy the internals separately?
It ships as a valve assembly, not a loose diaphragm or seal kit. For an MRO or property maintenance crew that means one line item covers the valve rather than piecing together internal components, though the bowl, supply stop and spud connection stay as installed.
