TOTO THU855 – Frequently Asked Questions
1) I have a TOTO auto flush valve leaking constantly, do I need the THU855?
If it's a 604E, 614E or 814E dual flush unit, the THU855 drain valve is the TOTO replacement part for that assembly. Check the model number on the unit body or the original submittal first, since TOTO service parts are model specific and the THU855 is called out for those three units only.
2) How many versions of the TOTO THU855 are there?
One. The THU855 drain valve is a single part, ordered under MPN THU855, with no finish or size choices to specify. Facility maintenance staff standardizing a building on TOTO dual flush units can stock the one number.
How fast can I get the TOTO THU855 delivered?
Most orders ship the same day from our distribution partners, with quick delivery throughout the
continental
U.S.
