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, drain the tank, and follow the valve’s instructions. If the shutoff won’t close, parts are corroded, or the toilet still runs after replacement, call a licensed plumber. Endless Energy offers toilet repair and replacement with same-day or next-day emergency service and transparent estimates across Greater Boston, including Newton and Cambridge.

Quick steps:

• Shut off supply and flush.
• Sponge out tank.
• Disconnect supply line; remove old valve.
• Install and adjust new valve.
• Restore water; check for leaks.
