The TOTO THU842#BN-A Push Button is a genuine TOTO replacement flush button designed for select 2-piece Aquia IV dual-flush toilets. Installed in the opening on top of the toilet tank lid, the two-button assembly activates the toilet’s 1.28 GPF full flush and water-saving 0.9 GPF reduced flush. Its brushed nickel finish provides a clean, sophisticated appearance that coordinates with other brushed nickel bathroom fixtures.
