home shelter, so as to make your available liquids last for 14 days.
(Many communities may continue to have potable water available, and
families could relax their rationing plans.)

In addition to water stored in containers, there is usually other water
available in most homes that is drinkable, such as:

--Water and other liquids normally found in the kitchen, including ice
cubes, milk, soft drinks, and fruit and vegetable juices.

--Water (20 to 60 gallons) in the hot water tank.

--Water in the _flush tanks_ (not the bowls) of home toilets.

--Water in the pipes of your home plumbing system. In a time of nuclear
attack, local authorities may instruct householders to _turn off_ the
main water valves in their homes to avoid having water drain away in
case of a break and loss of pressure in the water mains. With the main
valve in your house closed, all the pipes in the house would still be
full of water. To use this water, _turn on_ the faucet that is located
at the _highest_ point in your house, to let air into the system; and
then draw water, as needed, from the faucet that is located at the
_lowest_ point in your house.

In a home shelter, occupants should drink first the water they know is
uncontaminated, such as that mentioned above. Of course, if local
authorities tell you the regular water is drinkable, it should be used.

If necessary, "suspicious" water--such as cloudy water from regular
faucets or perhaps some muddy water from a nearby stream or pond--can be
