Every component inside a cistern has a job.
The Fluidmaster 400UK Bottom Entry Inlet Valve refills the cistern after a flush. The Fluidmaster 560 Series Universal Dual Flush Outlet Valve manages the flush, with adjustable full and half-flush settings. And when a compatible 400UK or 747UK inlet valve needs a new seal, there’s a replacement part designed specifically for the job.
Different roles. One cistern.
Fluidmaster has been developing toilet technology since 1957.
