Abstract
Abstract A one-man-operated valve in a dual pool system for simultaneously controlling the flow of water from a common water recirculating plant to the supply and drain conduits going to either one or the other of such pools. The arrangement of a tubular inner valve member for turning a limited distance within and relative to an outer tubular casing ported along its length to communicate the supply and drain conduits between the two pools and dividing the inner valve member into separate supply and drain zones each ported in sets segmentally offset circumferentially of each other on the inner valve members whereby upon limited turning of the latter only one or the other set of ports of the inner valve member can register with respective ports of the casing to effect flow from the common water recirculating plant to one or the other of such pools.
