The LAVELLE INDUSTRIES INC 528GT is a universal replacement toilet fill valve designed to fit all Toto toilet models. The fill valve controls the flow of water into the tank after each flush cycle, restoring water level to the set point before the next use. This unit features an adjustable refill ratio, allowing the technician to fine-tune water flow for consistent performance across varying water pressure conditions. Height is adjustable to accommodate different tank depths, making installation straightforward without additional hardware. Plumbers and experienced service technicians handle this type of repair as part of routine toilet maintenance.
The 528GT is intended for use in residential and light commercial applications wherever Toto toilets are installed. Its universal fit designation covers the full Toto toilet lineup, making it a practical stocking item for plumbers who regularly service Toto fixtures. The adjustable height and refill ratio settings reduce the need for model-specific parts on the truck, simplifying callback and preventive maintenance work in both single-family homes and multi-unit buildings.
Designed as a universal OEM-style replacement fill valve for all Toto toilet models.
Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply at the angle stop valve below the tank and flush to drain residual water before beginning work. Follow all applicable IPC requirements for toilet tank component replacement. Do not overtighten the locknut securing the fill valve shank to the tank, as this can crack the porcelain.
