TOTO THP3542 – Frequently Asked Questions

1) What is TOTO part THP3542?
THP3542 is a TOTO toilet repair harness supplied two types per bag, containing the valve assembly for a 1.0 GPF toilet. It is a replacement part for the toilet itself, not a fixture or trim item.
2) Will the TOTO THP3542 harness work on a 1.6 GPF toilet?
No. THP3542 is specified as a 1.0 GPF toilet valve assembly, so it is matched to 1.0 gallon-per-flush models. Fitting it to a 1.6 GPF toilet is not a flush volume match, and you should source the valve assembly listed for that specific TOTO model instead.
3) How many pieces come in a TOTO THP3542 harness bag?
The THP3542 harness ships two types per bag, so one order gets you both harness variants packaged together rather than a single piece. For a maintenance crew stocking TOTO 1.0 GPF toilets, that means one part number covers both.
