Value Brand HC550 toilet fill valve

Water-Saving Toilet Fill Valve

The Hydroclean HC550 is a replacement fill valve designed for standard toilet cisterns. It uses an anti-siphon mechanism to prevent backflow and protect the household water supply. The valve body is constructed from acetal, polypropylene, rubber and stainless steel for durability in continuous water contact. Homeowners and plumbers can install it as a direct replacement for worn or noisy inlet valves.

Anti-Siphon Protection and Material Build

The single specification that determines fit is the anti-siphon design, which meets backflow-prevention requirements for potable water systems. Buyers who need a valve without this safety feature or who require a specialised high-pressure or low-pressure model should look elsewhere. The mixed-material construction resists corrosion and scale build-up in hard-water areas. No adjustment tools are included in the package.
