Thanks for the link Gary. Have saved it to check out other things later. Definitely would not get that hose though. As Clare said, it would not be food grade, being a Garden hose.
Same as me Gary and Happy Wanderer - I fill my RV water tank with a black hose and have never had any problem with tainted water. I use tank water so whether that is the difference or not I am not sure.
DON'T get one of these hoses, cost us $50 PLUS NOZZLE in Big W. 2 uses and it sprang several leaks. Of course we were miles away from a store and no longer had the receipt to return product. Money wasted for us. Very disappointed thought it would have been very handy.
