Had a new radiator fitted a few months ago in our bathroom. the copper piping going into one end of the radiator keeps aving green goo build up on it after a few days, the other side is fine. It is simply a copper pipe going into I presume a steel fitting then attching to the rad.
Can anyone suggest what is causing this and is it worth getting the man who fitted it back in.
