Abstract
A method for applying teat dip to a dairy animal and backflushing a milker unit using a safety valve. The method includes the steps of: closing the safety valve to seal off the milker unit from a dairy pipeline system, forcing teat dip through the safety valve and a dip channel to a teat dip applicator on a milker unit teat cup, forcing backflush fluid through the safety valve and the milker unit, forcing water through the safety valve and milker unit, forcing air through the safety valve and the milker unit, and opening the safety valve so that the milker unit is in fluid communication with the dairy pipeline system.
