What is the most common cause of a running toilet leak?

The most common cause of a running toilet leak is a worn or misaligned flapper that doesn’t seal. A close second is a failing fill valve that keeps refilling. We repair both issues, from flapper replacements to full rebuilds, for homes in Odessa and nearby.

Quick checks:

• Add a few drops of food coloring to the tank; color in the bowl means the flapper leaks.
• Make sure the chain has slight slack and the flapper seats flat.
• If you hear hissing or see water into the overflow tube, suspect the fill valve.
