Ive got water constantly pouring from my overflow outlet from my cold water tank in my loft, it has been like this for a couple of weeks now. Speaking to a couple of guys at work they have said it will prob be the ball cock or seal that is replaced and that I should be able to do this myself.
Does anyone know how easy it is to do?? How do I know if it is the ballcock or seal that needs to be replaced?? And do I need to drain the water tank or that first??
