On the weekend I attempted to replace our kitchen faucet, but ran into a problem with removing the old one. I've attached photos of the faucet, and what it looks like under the granite counter-top. There isn't any sort of nut or below counter mounting hardware except for the C-Ring that appears to be holding the supply line in place. Note that when I turn the fixture, the supply lines rotate and don't cause that ring to move. I've tried to remove the ring from underneath with force, but haven't been able to get anywhere with it. In fact, if I didn't know better I would say that C-Ring is cemented in place. Any ideas or tips would be most appreciated! I'm stuck at this point.
