What it is

The PRO747UK is a Fluidmaster Pro side entry fill valve with a 1/2 inch plastic shank, for refilling toilet cisterns and storage tanks after flushing. It mounts through the side wall of the cistern and includes an anti-siphon design to prevent contamination of the water supply.

Signs this part needs replacing

  • The cistern refills slowly or not at all after flushing
  • Water keeps running or hissing after the cistern is full
  • Water hammer or banging in the pipework when the cistern fills
  • Visible leaking around the shank or float

Before you order

  • Confirm your cistern uses side water entry, not bottom entry
  • Check the connection is 1/2 inch
  • Isolate the water supply before removing the old valve
  • Have a spanner and PTFE tape ready for the shank connection
