Thats a great little contraption ill have to make one of those, i have 2x 9 litre kegs as well as my 18 litre jobs and i usually take one of these out to mates etc with my little keg charger and bronco tap but its always nice to have the choice.. Where did you source your materials, just the local hardware or brewshops?, the reason i ask is i have had trouble in the past finding food grade hose anywhere local!!
