The LAVELLE INDUSTRIES INC 5030BP is a complete adjustable flush valve kit designed for residential toilet tank repair and replacement. The kit centers on a 3-inch flush valve with adjustable height, allowing it to fit a range of tank depths without custom sizing. Included components are a Korky Plus Red Flapper, a tank-to-bowl gasket, and all required installation hardware, making this a single-purchase solution for a full flush valve service. Licensed plumbers and experienced DIYers install this kit when the existing flush valve is worn, leaking, or delivering inconsistent flushes.
This kit is suited for standard residential toilet tanks that accept a 3-inch flush valve. The adjustable height design accommodates varying tank configurations without the need for cutting or special modification. For future flapper-only replacement, the compatible flapper reference is TV 137-855. The package quantity is 3 units per package, making it a practical stocking item for plumbing service trucks or supply rooms handling multiple repair calls.
Designed for residential toilet tanks requiring a 3-inch adjustable flush valve. For flapper-only replacement on this valve assembly, use replacement flapper TV 137-855.
Installation is performed by a licensed plumber or qualified DIYer following local plumbing code requirements. Shut off the water supply at the angle stop and flush the tank completely to drain before beginning work. Remove all standing water from the tank before disconnecting the tank-to-bowl connection or removing the existing flush valve. Follow IPC guidelines for toilet tank component replacement and verify all connections are watertight before returning the fixture to service.
