Water can be found in many places throughout the average home. The first place is the water lying in the pipes. Whether you have a two story house, or single level home, find the lowest faucet in the system, this may even be a spigot outside. To get the water out effectively, open the highest faucet in the house, then open the lowest faucet and fill your clean containers which should be standing nearby. You could also leave some water in the pipes for later, but you probably won't get too many quarts out of the average plumbing system.
