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

Yes, you can replace a toilet fill valve yourself if you’re comfortable shutting off water and working inside the tank. Use a pro if the shutoff valve won’t close, parts are corroded, or leaks persist after install.

• Turn off water and drain the tank.
• Remove the old valve and gasket.
• Install the new valve and adjust float height.
• Reconnect supply line and check for leaks. Prefer not to DIY? Our licensed plumbers handle toilet repair and replacement in Rohnert Park, Petaluma, and Novato.
