A constantly running toilet means that the flapper isn’t sealing correctly or the fill valve is improperly adjusted. If the flapper is warped or damaged, turn off the water supply and empty the tank, then disconnect the flapper from the flush chain and unsnap it from the flush tower. Snap on a new flapper and reconnect the chain before turning back on the water.
If water is constantly running down the overflow tube, the fill valve needs to be adjusted. Turning the adjustment screw on the valve in one direction raises the water level and the other direction lowers it. The ideal level for a toilet tank is about an inch below the top of the overflow tube.
