Abstract

1,070,259. Water supplies; flushing. S. A. J. LILJENDAHL. Feb. 12, 1965, No. 6229/65. Headings E1C and E1X. [Also in Division F2V] A valve unit for preventing back suction into a piped water supply system from apparatus, such as a water closet, connected thereto comprises a chamber connected between a valve of the supply system and the apparatus, the chamber having at the upper end an air inlet which is closed by a valve that is raised in the chamber by a jet of water from the nozzle of the upturned inlet of the supply pipe of the system only as long as water is passing through the unit from the system to the apparatus. Two specific embodiments are disclosed.
