Abstract: A sink for washing tie-stall dairy farm milk pipeline systems includes a narrow trough at the bottom of the sink. The trough receives the inflations of milking machines placed in the sink for washing. The sides of the trough confine and constrain the inflations so that the machine does not tip over while in the sink. The water level remaining in the sink when the pipeline system is flushed through therefore can be small, leading to water savings of up to 30%. The trough is made from stainless steel sheets, bent to shape; the sides of the sink extend outwards and outwards from the trough at an angle, whereby the sink sides guide the inflations into the trough as the farmer lowers the milking machine into the sink.
