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

Yes, many homeowners can replace a toilet fill valve with basic tools. If the shutoff valve closes fully and parts aren’t corroded or leaking, it’s a reasonable DIY.

Quick checks:

• Turn off the supply and drain the tank.
• Remove the old fill valve and supply line.
• Install the new valve and gasket; reconnect the line.
• Adjust water level and test for leaks.
