Fixing a running toilet often involves checking the flapper and fill valve. First, inspect the flapper at the bottom of the tank; if it's worn or warped, replace it. To adjust the fill valve, close the toilet's shut-off valve and flush to empty the tank. Adjust the fill valve according to manufacturer's instructions so the tank stops filling at about an inch below the overflow pipe. Turn the water back on and test. If the toilet continues to run, consider replacing the fill valve or consulting a professional.
