How to unscrew shower hose to cut the leaking part of hose:

I found a crack or tear inside shower card near to end. I've successfully unscrew the shower head, but not able to unscrew the remaining, so that I can cut the damaged part out... it looks like new and shiney, but it's very tightout there... Are there any tips to unscrew the bit.

If you are saying that the hose is split close to the hand held shower head and you unscrewed the head from the hose, I don't think that you can get the other part loose from the hose and cut off the split and install the old piece in the cut off hose and make it seal. Those pieces are crimped on at the factory.

If this is not what you are talking about then let us know.
