TOTO THP3530X – Frequently Asked Questions
1) What is the TOTO THP3530X part?
THP3530X is a TOTO toilet valve assembly for 1.28 GPF tanks. It is a replacement valve unit for the toilet itself, not a trim or supply-stop part, so order it when the fill or flush valve assembly in a 1.28 gallon per flush TOTO toilet needs to be swapped rather than rebuilt piecemeal.
2) Will the THP3530X valve assembly work in a 1.6 GPF toilet?
No. The assembly is specified for 1.28 GPF operation, so it belongs in a 1.28 gallon per flush TOTO toilet. Dropping it into a 1.6 GPF or a higher-volume older tank means the flush volume no longer matches what the bowl was engineered for. For a 1.6 GPF fixture, look up the valve assembly listed for that model instead.
3) What part number should I give my supplier for the TOTO 1.28 GPF toilet valve assembly?
Order it as TOTO THP3530X. That is the manufacturer part number for the 1.28 GPF toilet valve assembly, and it is the only number you need on the purchase order. TOTO repair parts run in tight families where the prefix and suffix both matter, so quote the full THP3530X rather than a shortened version.
4) I manage apartments with TOTO toilets. Is this a plumbing repair part I can stock for turnovers?
It is a plumbing repair part, catalogued for toilet use as a valve assembly, so it is the kind of item property maintenance groups keep on the shelf for 1.28 GPF TOTO fixtures. Standardizing on one flush volume across a building is what makes stocking a single valve assembly practical: confirm the toilets in your portfolio are 1.28 GPF models before you buy quantity, since the assembly is volume specific.
