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 the water, drain the tank, swap the valve, and check for leaks. If the shutoff won’t close, parts are corroded, the tank or base leaks, or the toilet keeps running, book a pro. We repair faulty fill valves, leaks, clogs, and weak flushes, and we carry parts for fast fixes. For a quick check, add a few drops of food coloring to the tank; color in the bowl without flushing means a leak. We serve Denver and Thornton.
