The PRO45 is the most trusted fill valve in the industry and the PRO45B is that same valve but includes a brass shank. This kit also includes our reliable, chlorine-resistant 501 flapper that includes the extra benefit of built-in Microban® technology, which fights flapper breakdown due to bacteria on the flapper itself.
