A running toilet usually indicates a problem with the fill valve, flapper, or flush valve. Often, the flapper does not seal properly, causing water to continuously leak into the bowl. Checking and replacing the flapper can often solve the issue. If that doesn’t work, inspect the fill valve and flush valve for defects or misalignment. Regular maintenance and adjustment can prevent these issues from recurring.
