If you're cross-shopping dual-flush toilets beyond Delta, the following brands also ship in this category:
A dual-flush toilet has two buttons (or a split lever): a half-flush for liquid waste — typically 0.8 to 1.1 GPF — and a full flush for solids at 1.28 to 1.6 GPF. The water savings are real over a year. The maintenance reality is less talked about.
A standard 1.28 GPF toilet uses a single flush mechanism — flapper or piston — that releases a fixed volume of water with each flush. A dual-flush uses a cylinder-style flush valve with two trip points: pressing the smaller button (or pushing the lever down) opens the valve for a shorter duration; the larger button opens it longer. The 3-inch or 4-inch valve seat at the bottom of the tank is larger than a traditional flapper, allowing higher-velocity water release in less time.
