Can I replace a toilet fill valve myself without professional help?

Yes, many homeowners can replace a toilet fill valve with basic tools.

  • Turn off water and drain the tank.
  • Disconnect the supply line and remove the old valve.
  • Install the new valve and gasket; hand-tighten the locknut.
  • Set the float to the tank’s water line; restore water; check for leaks. If the shutoff is stuck, the supply line is brittle, or the toilet still runs, call a plumber. We serve Roanoke, Cave Spring, and nearby communities.
