摘要： A poultry drinker system (10) includes a number of drinker lines (12) each supplied from a common high pressure water supply (16) through a water pressure regulator (20). Each regulator (20) includes a reference spring (76) establishing a default minimum water pressure. A centralized remote control system (26) provides regulated low pressure air (36) to the water pressure regulators (20) to augment the reference spring force and remotely adjust the water pressure in the drinker lines (12). The remote control system (26) periodically applies higher pressure (34) to the water pressure regulators (20) to increase water pressure and flow rates and sequentially flush the drinker lines (12). The remote control system (26) includes a source of high pressure air (34), an air pressure regulator for supplying lower pressure air (38) and a stack of 3-way valves (32) for applying low or high pressure air to each water pressure regulator (20).
