Hi, I want to replace one of my 100m extension hoses. Does anyone know of a company that supplies minbore or microbore 'hot water' hose, a colour other than red? I like to have 2 different coloured hoses in the van - it stops any confusion when 2 are working together. I prefer hot water hose, but already have a red one (GrippaHose HydroHeat). Thanks.
