TOTO THU863R-A – Frequently Asked Questions
1) Can I use the THU863R-A flush valve on a standard exposed two-piece toilet tank?
No. THU863R-A is built for a TOTO in-wall (concealed) tank, where the splash guard and actuator work behind the wall panel. A standard exposed china tank takes a conventional flush valve and flapper instead.
2) Is TOTO THU863R-A a complete in-wall tank or just the flush valve?
Just the valve side. THU863R-A is the flush valve with splash guard and actuator for an in-wall tank, so the tank body, carrier, and bowl are separate items. If you are replacing the whole concealed tank system you need the tank assembly, not this part.
3) What is the TOTO part number for the in-wall tank splash guard and actuator?
Order it as TOTO THU863R-A. That is the manufacturer part number for the splash guard/actuator flush valve for an in-wall tank, and it is the only configuration offered.
4) I manage a building with TOTO concealed-tank toilets. Is this the right repair part for a weak or leaking flush?
For TOTO in-wall tank toilets, THU863R-A is the flush valve assembly with the splash guard and actuator, which is the part that opens and closes on each flush. It is a maintenance part for that concealed tank system. Match it to the specific in-wall tank model you have on the wall before stocking it across a fleet of fixtures.
