TOTO THP3529X – Frequently Asked Questions
1) What is TOTO part THP3529X?
THP3529X is a TOTO toilet valve assembly, supplied as a replacement flush valve part rated for 1.0 gallon per flush operation. Order it by the TOTO part number THP3529X so you get the 1.0 GPF assembly rather than a higher-volume version.
2) Will the THP3529X valve work in a 1.28 or 1.6 gallon TOTO toilet?
No. The THP3529X assembly is the 1.0 GPF valve, so it is matched to a 1.0 gallon per flush TOTO toilet. Putting it in a 1.28 or 1.6 GPF bowl changes the flush volume the bowl was engineered around, which usually means poor bowl clearing. For those tanks, use the TOTO valve assembly specified for that flush rate.
3) I manage apartments with TOTO 1.0 GPF toilets - is this the right part to stock for flush repairs?
For TOTO toilets rated at 1.0 gallon per flush, THP3529X is the TOTO-supplied valve assembly, so it is a reasonable spare to keep on the shelf if your fleet is standardized on 1.0 GPF models. Check the model number on each tank first, because TOTO uses different THP valve assemblies across flush rates and tank designs.
4) Is THP3529X a genuine TOTO part or an aftermarket flush valve?
It is a TOTO-branded valve assembly carrying TOTO's own THP3529X part number. That matters on TOTO tanks because the trip lever, overflow height, and seal geometry are specific to the model family, and a generic aftermarket flush valve often will not seat or set the correct water line.
