Why does my toilet keep running after flushing?

A constantly running toilet is almost always caused by a faulty flapper valve, a float set too high, or a worn fill valve. Start by checking the flapper — if it does not seal flat against the drain seat, replace it. This is a $5-$10 fix that takes under 10 minutes.

How do I unclog a toilet without a plunger?
