I want to change a washer on someone's hot water tap but the stopcock between the cistern and the hot water cylinder is too stiff to turn off by hand. If I put a screwdriver in the stopcock wheel to get more leverage I'm scared that I'll deform the copper pipes. Any tips on what I can do apart from putting a new stopcock on?
