TOTO THU847-A – Frequently Asked Questions
1) Will the THU847-A work on my TOTO toilet, or do I need the part number off my model?
Match it to the part TOTO calls out for your specific toilet. THU847-A is a model-specific dual flush tower for a TOTO one-piece toilet, and TOTO tank internals are not interchangeable across series. Pull your toilet's model number (usually stamped inside the tank or on the china behind the seat) and confirm THU847-A is the tower TOTO lists for it before ordering.
2) My TOTO one-piece toilet runs constantly, is the flush tower the part to replace?
A toilet that runs after the flush cycle ends is usually failing to seal at the flush valve, and on a TOTO tower-style dual flush that seal is part of the tower assembly, THU847-A. If instead the tank overfills and spills into the overflow, the fault is the fill valve, not the tower, and this is the wrong part for that.
3) Can I standardize a building's TOTO dual flush toilets on the THU847-A tower?
Only where the fixtures are the same TOTO model. THU847-A is one specific one-piece dual flush tower, so it covers the openings running that toilet and nothing else. For a mixed fleet, inventory the model numbers first, then stock the matching tower per model rather than assuming one part covers the floor.
4) Does the TOTO THU847-A come with a fill valve or tank-to-bowl gasket?
No. THU847-A is the flush tower assembly by itself. The fill valve, supply line, tank bolts and any tank-to-bowl hardware are separate parts. If you are doing a full tank rebuild rather than chasing one fault, plan on ordering the fill valve and gasket alongside it.
5) Is the THU847-A a genuine TOTO part or an aftermarket flush tower?
It is TOTO's own part, sold under TOTO part number THU847-A. For a dual flush tower that matters more than usual, since the two flush volumes are set by the tower geometry and an aftermarket substitute can change how much water each button delivers.
