we recently bought a gelert water carrier,the sort you can roll up when not in use..we were on a rally in yorkshire and it was a fair clip to the tap and we discovered the coffee tasted like chlorine and other peoples water was fine so we assumed it was the water but other peoples water was fine so we tried it again at a campsite in ashbourne(new house organic farm)same thing but luckily we had a tap near by.So we took it home and boiled it..sterilized it..flushed it..you name it it took ages to get the smell/taste off it so although i dont recommend it if you do see one and you have no choice ..smell it!
