I agree, unless it's from damage to the hose, once they fail , they usualy fail again pretty quickly, If I have one that fails I might get it fixed, but then I put it back as a spare, or for those times when you need that little extra hose.
Why does it always seem that you end up 5ft short, then you have to think, do I get out another section of hose or do I try to move the truck closer. After all these yrs I still never get it right the first time.
