Valve Leakage Test
The Milk Valve Leakage Test is used to determine the presence of
any vacuum leakage through the milk valve closing off the vacuum
to the milking cluster when the milking valve is in a closed
position.
Equipment required:
1. One standard Ping-Pong ball. Go
here for Ping-Pong balls.
Testing procedure:
1. During the milking process, go to any unused or unattached
milking unit and remove milk hose from milk valve.
2. Hold the Ping-Pong ball close to the closed milk valve.
3. The ball will snap to the outlet of the milk valve if any
vacuum leak exists.
4. If no leakage the ball will remain in hand or fall to the
floor.
This test should be performed on either a monthly or a weekly
interval depending on type of valve being used any leakage of
this valve during milking can predispose to mastitis conditions
very rapidly.
