I just had the outside tap (and pipe leading to it) replaced by a "handyman". Unfortunately, he failed to secure the new pipe in the brick so that it wouldn't turn when the tap was opened or closed. The old pipe had some sort of putty material around it which is still there (but is no longer serving its purpose). I don't know what material it is. If someone can tell me then I can just replace it. As of right now I'm not sure what the best way to secure the pipe is...
