In reply to sabbott:
Its definitely over 3 years old ( bought in 2014) and out of warranty, I accept that, it was just the surprisingly poor answer from Alpkit, that got me, "We don't offer replacement parts I'm afraid just for a safety issue"
Not that I was after a warranty repair, I actually asked to buy a new hose, but surely a significant safety issue on a product that clearly has history of such issues should be honoured!!
