Hi Bill. Thanks for your response and sorry for the photo. Don’t know why it is sideways. Here is a better one I hope. The leak is coming from the black valve. Everything above it is dry. I tried to seal the leak using silicone and added a 2nd valve under it, but the silicone did not seal the leak so I need to replace the valve. I just can’t figure out how to remove the metal (crimp) band holding it. Any ideas how to remove that so can put a new valve in? We have a 2007 2720SL.
