ABSTRACT:
A T-shaped flow divider for use in watering and irrigating systems, with a swivel inflow connector, and a four-position three-hole ball control valve to direct the outflow to one or other or both of the T-arm outflow connectors, or to close off flow completely. The swivel feature permits the outflow connectors to swivel to any convenient circumferential location while the inflow connector is attached to a water supply source. This obviates the need for complete dismantling of rigid systems with 2-way valves for maintenance or changes in the system. Further, the 4-way control valve permits the accurate design of extended irrigation systems, particularly for irregular areas. One version of the flow divider has female threads on the swivel inlet flow connector for attaching to hose bibs and the like, with male threads on the outflow connectors.
