Fluidmaster Inc K-400H-039-T14 Fill Valve Flapper Kit

Product Description

The FLUIDMASTER INC K-400H-039-T14 is a complete toilet repair kit that combines a high-performance fill valve with a 2-inch water-saving flapper in a single package. The fill valve features an anti-siphon design that meets code requirements and adjusts in height from 10 inches to 15 inches to fit most standard toilet tanks. The flapper includes a dial adjustment for customizing flush volume, and its solid frame delivers a secure, consistent seal. Hard water-resistant materials and built-in antimicrobial technology help resist bacterial growth and material breakdown over time. This kit is installed by plumbers and experienced DIYers to address noisy, running, or weak-flushing toilets.

This kit is designed for residential toilets with 2-inch flush valves. It addresses common toilet malfunctions including phantom flushing, continuous running, and weak flush performance. The fill valve's tank and bowl water level adjustment dials allow technicians to dial in water use without additional tools. The height-adjustable fill valve body accommodates varying tank depths, reducing the need for multiple SKUs on a service call. Compatible with a wide range of toilet brands and models that use a 2-inch flush valve configuration.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Before beginning, shut off the water supply at the angle stop below the tank and flush to drain remaining water. Remove the old fill valve and flapper, then install the new components per the manufacturer's instructions, adjusting height and water level dials before restoring supply. Verify there are no leaks at the fill valve shank connection and that the flapper seats fully before returning the toilet to service.
