why is my toilet overflow pipe dripping?

it sounds like your cistern is filling too high. lift the lid off. then first check the ball-cock valve is working correctly. flush the toilet and while it is refilling, pull up the ball-cock and the water should stop completely. if water continues coming through then the valve is the cause, if not then adjust the screw under the ball-cock arm which will set the level at which the water stops filling.
