When changing the toilet flapper you need to know if you have a 2, 3 or 4 inch flush valve.
For 2 inch flush valves the Korky Ultra Water Saver Flapper is the most universal 2 inch flapper available. The flapper adjusts to match original toilet settings and eliminates water waste by decreasing the amount of water flushed.
Ideal for all standard 2 inch toilets, including: 1.28, 1.6, 3.5 and 5 gallons per flush (gpf). The flapper resists chlorine, bacteria, city water treatment, hard water, and well water.
The adjustable flapper has multiple settings to ensure it fits popular 2 inch toilet models: American Standard Cadet (4029, 4078, 4083, 4053, 4650), Monarch (4003), Mainstream (4061), Evolution 2 Flowise (4061), Kohler Wellworth (K-4620), Wellworth (K-4519), and TOTO (706).
