The LAVELLE INDUSTRIES 612011919 is a replacement toilet flapper designed for use with Toto toilet models. The red flapper is a critical component in the flush valve assembly, creating a watertight seal at the bottom of the tank to hold water between flushes. When the flush handle is activated, the flapper lifts to release water into the bowl, then reseats to refill the tank. This part is installed by licensed plumbers and knowledgeable DIYers performing routine toilet repair or leak diagnostics. A worn or deteriorated flapper is one of the most common causes of a running toilet and constant water loss.
This flapper is suited for residential toilet repair applications where a Toto-compatible replacement flapper is required. It is intended for use in standard gravity-fed tank toilets. The red designation typically indicates a specific flapper size or flush valve seat diameter, ensuring proper fit and seal on compatible Toto toilet models. It is a direct drop-in style replacement, making it a practical choice for routine maintenance and service calls.
Designed as an OEM-style replacement flapper for compatible Toto toilet flush valve assemblies. Verify flush valve seat diameter and flapper peg or ring mount style before installation to confirm fitment.
Toilet flapper replacement is a standard plumbing maintenance task performed by licensed plumbers or experienced DIYers. Before servicing, shut off the water supply at the fixture stop valve and flush the toilet to drain the tank. Disconnect the old flapper from the flush valve pegs and the lift chain from the flush handle arm, then install the new flapper in reverse order. Adjust chain length to allow full flapper lift without slack that could cause the flapper to seat improperly.
