Remember Macgyver!? I think there was a reason why he always carried a half-used roll of Duct Tape with him. It's so useful.

I think PrincessPerky is right about leaks. Eventually the sticky adhesive will wear away and the water will eventually get through. This has always happened to me. Get a hose repair kit if it's less than getting a new hose - which may go through the same Wear & Tear process.
