Don't forget the opposite! One occasionally sees a water tap of some sort, which is explicitly *not*potable *not* drinkable.
The International Plumbing Code (IPC) section 608.8 covers marking of non-potable sources. Curiously the requirement is in English. Have a read: http://publicecodes.cyberregs.com/icod/ipc/2009/icod_ipc_2009_6_par133.htm Recent amendments to 608.8.2 specify the use of purple colored piping for such systems with rain and graywater. --------------- The same issue comes up as with potable: the water is non-potable according to whom? Does the sign explicitly describe a hazard with the water, or simply state that the authority has not certified the water.
