Lavelle Industries Inc 100BP Adjustable Toilet Flapper

Product Description

The LAVELLE INDUSTRIES INC 100BP is an adjustable, ultra water-saving toilet flapper designed to replace worn or leaking flappers in standard 2-inch flush valve toilets. The flapper is constructed from flexible red rubber that resists chlorine, bacteria, city water treatment chemicals, hard water, and well water conditions. It ships with one adjustable flapper and one stainless steel chain. The adjustable design allows the technician or installer to dial in flush volume to match original toilet settings, reducing unnecessary water waste per flush cycle. This part is suited for licensed plumbers and experienced DIYers performing routine toilet maintenance or low-flow retrofit work.

The 100BP is rated for toilets flushing at 1.28, 1.6, 3.5, and 5 gallons per flush, covering a wide range of residential toilet vintages.
