Why a toilet keeps running

A running toilet almost always comes down to one of four parts: a worn flapper that no longer seals, a fill valve that never shuts off, a float set too high so water spills into the overflow tube, or a flush chain that is too short and holds the flapper open. Any one of them can waste 200+ gallons a day.

The dye test

Put a few drops of food coloring in the tank and wait 15 minutes without flushing. Color in the bowl means the flapper is leaking. That is a ten-dollar part — but if the seat is corroded, the flapper alone will not fix it.

When to call a plumber

If the toilet still runs after a new flapper, if the fill valve is spraying, if the toilet is more than 15 years old, or if you hear water running from inside the wall, it is time for professional toilet repair. Older toilets are often worth replacing with a water-saving model instead of repairing repeatedly.
