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