The LAVELLE INDUSTRIES INC 2017BP is a universal 2-inch adjustable toilet flapper engineered for long-term performance in demanding water conditions. Manufactured from a proprietary Chlorazone II rubber compound, this flapper is rated to last twice as long as standard flappers. It resists chlorine, bacteria, city water treatment chemicals, hard water, and well water. The adjustable design features multiple settings to reduce the volume of water released per flush, cutting water waste on every cycle. Plumbers and facility maintenance technicians install this part as a direct replacement in standard residential and light-commercial toilet tanks.
The 2017BP is designed for all standard 2-inch toilet flush valves and covers a broad range of flush volumes including 1.28, 1.6, 3.5, and 5 gallons per flush. It is compatible with American Standard Cadet models 4029, 4078, 4083, 4053, and 4650, Monarch 4003, Mainstream 4061, Evolution 2 Flowise 4061, Kohler Wellworth K-4620 and K-4519, Toto 706, and many additional models. Each kit ships with one adjustable flapper, one stainless steel chain, and an instruction sheet.
Fits American Standard Cadet 4029, 4078, 4083, 4053, and 4650; Monarch 4003; Mainstream 4061; Evolution 2 Flowise 4061; Kohler Wellworth K-4620 and K-4519; Toto 706; and many additional standard 2-inch flush valve toilets accepting 1.28 to 5 GPF operation.
Installation is performed by a licensed plumber or qualified maintenance technician. Shut off the toilet supply valve and flush to drain the tank before removing the old flapper. Disconnect the existing chain and lift off the worn flapper from the overflow tube ears. Snap the 2017BP onto the overflow tube, attach the stainless steel chain to the flush handle arm with minimal slack, and select the appropriate adjustment setting before restoring water supply. Follow all applicable IPC and local plumbing code requirements for fixture repair.
