One of the two primary pieces of equipment inside your toilet tank, the flush valve controls the flow of water from the tank to the bowl. There are several different styles, but they all use a flapper that is raised when you push down the flush handle on your toilet, which drains the tank. When the tank is empty, the flapper lowers itself over the drain, and allows the tank to fill back up again.
If you find that your toilet is running constantly, this may be due to an old or damaged flush valve. If you are comfortable opening your toilet tank yourself, inspect the valves and check for broken pieces or cracked and corroded rubber gaskets that could be causing your problem. Even if you're not comfortable doing repairs or installations yourself, this visual inspection will make it much easier to explain the situation to a hardware store worker or professional plumber.
If one of these flappers is all you need, one of these high-quality flapper options might be exactly what you're looking for.
When you're replacing your toilet's flush valve, make sure to cross-check it with your toilet model to make sure it will fit. There are many different toilet and valve brands on the market, most of which use different measurements and designs that must be matched with the correct valve. Some toilets are just too old to fit modern flush valves, in which case it may be time to buy a new toilet. This collection of toilet options gives a nice variety of styles and prices to choose from.
