Lavelle Industries Inc 528 Quietfill Toilet Fill Valve

Product Description

The LAVELLE INDUSTRIES INC 528 is a universal toilet fill valve designed to replace noisy, slow-filling, or constantly running ballcock and fill valve assemblies. Commonly sold under the Korky brand, this quietfill valve adjusts from 7.75 inches to 13.5 inches in height using a twist-lock mechanism, allowing installation without tools. It fits a wide range of one-piece and two-piece toilet designs across most major brands. The kit ships complete with everything needed for a direct swap: a fill valve, refill tube, metal refill tube clip, mounting nut, cone washer, coupling nut, tamper-proof key, and instructions.

This fill valve is suited for residential toilet service where the existing ballcock or fill valve is causing noise, slow tank refill, or continuous running. The twist-lock height adjustment and universal inlet threading make it appropriate for a broad range of toilet tank configurations found in both new and retrofit plumbing work. Licensed plumbers and experienced DIYers typically handle this installation as a routine service call or owner repair.

Installation Notes

Shut off the water supply at the stop valve below the toilet tank before removing the old fill valve or ballcock. Flush the tank to drain residual water before disconnecting the supply line and unscrewing the existing valve. No special tools are required for this replacement; standard plumbing practice under IPC guidelines applies. Verify the adjusted height seats the valve correctly before tightening the mounting nut and restoring water supply.
