I have got some red hose, Looks just like clear braided garden hose,but with a red coating. It is apparently what they use in caravans for hot water, Don't really know how or where as I do not caravan. I was in a local garage and asked if they had radiator hose that hozelocks would fit on. Said they never but had this stuff in (after I explained what it was for). It works fine so far, But early days.
