Thanks Jim, yes exactly the same fault for me, I will do a similar repair until I can find a replacement hose, I have had this hose off before and it appears fine, I wonder if the spout on the tank softens with the heat and time and is compressed by the clamp? allowing the connection to fail and leak? Such a small issue that would cause a major problem.
I will let you know how I get on.
Thanks again for your help
