Why is water constantly running in my toilet?

Perhaps the most common reason for a running toilet is an old flapper that needs to be replaced. When flappers get old, they don’t seal the way they should, and this allows water to pass constantly from the toilet tank into the bowl. Shut off the water supply to the toilet, and then flush the toilet to drain the water.

What is the flush valve size?

2 inches
The standard size of a flush valve is 2 inches. This size is what you’ll likely find at a home improvement store and should work on most toilets, including low-flow and older models with larger tanks.

Why won’t my toilet stop running?

The water level in the tank is controlled by an adjustable float. A float that’s set too low produces a weak flush; if it’s set too high, water spills into the toilet overflow tube and the fill valve won’t shut off. The toilet keeps running. Keep adjusting the float until the water shuts off at the proper level.
