running toiletWe’ve all heard a toilet keep running long after it should have stopped and most likely had confused thoughts about what to do next. Sometimes, it seems like just another thing to put on your to-do list, but if you know what causes a running toilet, you can troubleshoot the problem right away and determine if it’s something you can fix on your own.

The most common reason for a running toilet is that the flapper at the bottom of the toilet’s tank is staying partially open, instead of adequately sealing shut. This could be the result of a few different factors:

  • A broken handle
  • Aging materials that need to be replaced
  • Not enough tension attached to the handle of the flapper

Another common problem is that the toilet will randomly start running even when it has not recently been used. This is usually still the result of the flapper not having an adequate seal. Generally speaking, this seal can be replaced so your toilet stops running, and this is usually an easy fix.
