hi i did unscrew it first then take the sphere out but it was already broken ! ok how do you take the old pipe out then i have un screwed the pipe yet it doesnt seem to want to come out ? quote name='Johndouglas' date='Aug 30 2008, 06:26 PM' post='33564'] If you had used the search facility on this site you would have found the instructions for removing the antisink sphere. Those are that before undoing the sphere, the 9mm pipe union at the back of the sphere must be loosened first, otherwise - well, you know what happens now. You'll have to loosen off the other end of that broken pipe and get a replacement. Also get two new seals.
