Using specialized filters, dosing devices, pressure regulators, water cups, and nipples (Jinshida, Pulasong, LUBING) for aquaculture, each layer is equipped with an independent pressure regulator to ensure more stable water pressure. Equipped with dual water lines, each chicken can drink water from two nipples, ensuring more sufficient and even drinking water for the chickens. Equipped with a dedicated backwashing device, no pressure regulator is used for backwashing, and the sewage from the flushing water line is directly discharged outside the house. The drinking water system is equipped with a water shortage alarm, which will sound an alarm when the water pressure is low.
