Many homeowners in the Coachella Valley deal with the nuisance of a constantly running toilet, but many don’t know why this happens or what they can do about it. In most instances, the cause of a toilet that continuously runs is that the flapper doesn’t close to form a proper seal. You’ve probably heard the advice to “just jiggle the handle” as a way to solve this problem. However, when the flapper fails to seal, the water leaks into the toilet and never fills up the tank to activate the floater to shut it off. The solution to this problem is to replace the flapper, which is an easy and inexpensive repair you can usually do yourself.
