ABSTRACT:
The present invention is directed to a shut-off valve for a suction drainage system wherein flow of waste to a disposable container is stopped at a pre-determined volume which is less than the maximum capacity. A tubular sleeve is coaxially located around the shut-off valve. The shut-off below the maximum volume allows a safety margin for the waste container to be capped off without spilling or geysering.
