Showerhead clogged after water for my condo building was shut off. I have a Kohler showerhead with a ball and socket. I have managed to remove the showerhead, but can't get the plastic ball socket out of the neck, so I can remove the debris causing the clog. I've tried to dislodge it using pliers, a wrench and vise grips, but it won't move. Any ideas? Should I try to unscrew the neck? Help!
