Why Your Toilet Keeps Running (And What It's Costing You)

A running toilet can waste hundreds of gallons a day. Here's what's happening inside the tank and how it gets fixed.

A toilet that runs constantly can waste hundreds of gallons a day. The cause is usually inside the tank.

The two common offenders are a worn flapper and a faulty fill valve. A float set too high also sends water down the overflow tube.

Test it: add food coloring to the tank and wait; if color appears in the bowl, the flapper is leaking. A pro can fix stubborn or recurring issues.
