A toilet that continues running after a flush is more than an annoying sound. Water may be continuously moving from the tank into the bowl, increasing water use and sometimes getting worse as internal components wear.

Why does a toilet keep running?

Common causes include a flapper that is not sealing properly, a fill valve that does not shut off at the correct level, an incorrectly adjusted float, a chain that is too tight or tangled, or problems with the flush-valve sealing surface. The exact cause should be confirmed before parts are replaced.

Simple checks homeowners can make

Remove the tank lid carefully and watch what happens after a flush. Check whether the flapper closes fully and whether the water stops before reaching the overflow tube. Avoid forcing or modifying components if you are unsure how they operate.

When should the toilet be repaired?

If the toilet runs repeatedly, refills on its own, requires handle-jiggling to stop, leaks around the fixture, or has damaged internal components, professional service can identify whether a straightforward repair or fixture replacement makes more sense.

Repair or replace?

Many running-toilet problems can be corrected by servicing the tank components. Replacement may be worth considering when the fixture itself is damaged, unreliable, difficult to repair, or has several problems at once.
