Any advice on freeing up a seized stop cock. I'm trying to change the washer on the tap but the stopcock before it is completely seized. The one controlling water into the house works ok, but i don't want to close it off there and drain the tank down. Brute strength is starting to damage the handle and I'm worrying about breaking it :( via /r/DIY http://ift.tt/2xTGLkL
