Abstract
Described is a limited-demand water supply system for use in residential homes wherein a supply of water is automatically provided to fire sprinklers by means of air pressure. Multiple tanks or vessels in a connected fluid system are partially filled with water and then pressurized with air pressure provided by an air compressor. There is maintained sufficient air pressure to empty the water in the vessel system through the fire sprinkler heads, when open. Preferably, to efficiently comply with most current fire system regulations, a set of vessels of less than about 200 gallons capacity each is filled about two-thirds with water and then air-pressurized to about 150 pounds per square inch.
