Abstract

A fill valve for a toilet tank includes a multi-piece shank assembly. The shank assembly includes a first hollow member coupled with a second hollow member using a snap joint. The first hollow member has a tortuous outer surface, which together with the second hollow member forms a plurality of flow paths. The flow paths are configured to reduce water noise. The first and second hollow members are provided separately, resulting in simplified molding process and improved assembly automation.
