TOTO THU6401#01 – Frequently Asked Questions

1) What exactly comes with TOTO THU6401#01?
THU6401#01 is a TOTO toilet tank lid assembly part supplied as a set of two lid bumpers in Cotton (#01) white. The bumpers are the small pads the tank lid rests on, so the lid seats level and does not rattle against the china.
2) Is the TOTO THU6401#01 a full tank lid or just the bumpers?
Bumpers only. Despite the D-shape lid assembly naming, what ships is the pair of Cotton lid bumpers, not the ceramic tank lid itself. If you cracked a lid, you need the replacement lid for your specific toilet model, not this part.
3) Will these Cotton bumpers match my TOTO toilet color?
The #01 suffix is TOTO's Cotton white color code, so these match any TOTO fixture ordered in Cotton. On a Colonial White, Sedona Beige, Bone or Ebony tank the bumpers would be a visible mismatch only where they sit under the lid edge, which is largely hidden once the lid is seated.
4) My TOTO tank lid rocks and clinks when the toilet flushes. Is this the fix?
Usually, yes. Worn, flattened or missing bumpers let the lid shift and tap against the tank rim, and a rocking lid is the most common cause of that rattle. Replacing both bumpers at once, which is how THU6401#01 is packed, keeps the lid sitting level rather than tipping toward the older pad.
5) For a property with several TOTO toilets, can I stock one bumper part for all of them?
THU6401#01 is specified for TOTO D-shape tank lids in Cotton. TOTO uses different lid shapes across its one-piece and two-piece lines, so match the part to the lid profile on the tanks you maintain rather than assuming one bumper set covers the whole building. Where the lids are the D-shape Cotton style, this is the part to shelf.
6) Do I need tools to install TOTO lid bumpers?
No plumbing work is involved. The bumpers sit between the tank lid and the tank rim, so the job is lifting the lid off, removing the old pads, setting the new ones in place and replacing the lid. The tank does not need to be drained and no supply line is disturbed.
