Brass Craft Service Parts BCT021 Toilet Fill Valve Kit

Product Description

The BRASS CRAFT SERVICE PARTS BCT021 is an adjustable anti-siphon toilet tank fill valve and flapper kit designed for residential toilet repair and replacement. The kit includes a fill valve, refill tube, and Hornet V toilet flapper. The fill valve features a quarter-turn adjustment mechanism that allows height setting anywhere from 9 inches to 14 inches, making it compatible with a wide range of standard toilet tanks. This kit is installed by plumbers and experienced DIYers performing toilet maintenance or upgrades without replacing the full flush assembly.

The BCT021 is suited for residential toilet tank service where the existing fill valve or flapper has failed or is performing poorly. The adjustable height range covers most standard two-piece and one-piece toilet tanks. The anti-siphon design meets standard backflow prevention requirements for potable water systems. The included Hornet V flapper provides a direct replacement for the flush seal, allowing both components to be replaced in a single service call.

Compatibility

Designed as a replacement for most old-style toilet tank fill valves and float assemblies in standard residential toilet tanks requiring a fill valve height between 9 inches and 14 inches.

Installation Notes

Installation is performed by a licensed plumber or qualified DIYer. Shut off the water supply at the angle stop valve below the toilet and flush to drain the tank before removing the existing fill valve. The IPC and local plumbing codes govern toilet fill valve replacement in most jurisdictions. Do not overtighten the locknut securing the fill valve to the tank; hand-tight plus a quarter turn is the standard practice for plastic fill valve shanks.
