About This Product
Got a one-piece toilet that's running constantly or not flushing right?
This flush valve replacement kit is a solid fix.
It's designed to work with most top-push-button one-piece toilets – including TOTO, Glacier Bay, Project Source, Deer Valley, HOROW, WOODBRIDGE, and Fine Fixtures.
It matches the structure of the TOTO THU338, so it's a drop-in replacement for a lot of popular models.

You'll want to measure first though – it fits drain openings from 2.

56 to 2.
95 inches and tank heights between 9.
5 and 14.

6 inches (including the lid).
Not for two-piece toilets, sorry.
The dual-flush system lets you choose a partial flush for liquid waste and a full flush for solids, saving water without sacrificing power.

The rubber seals and silicone flap create a tight seal that stops leaks and backflow, and the reinforced ABS body with a metal base stays sturdy over time.

It's cUPC certified too, so it meets U.
S.
plumbing standards.
Good upgrade or replacement if your old valve is acting up.
