A drain assembly for a fluid collection container includes a housing attached to the container and defining a cavity therewithin. A stop is located within the cavity and is fixed relative to the housing. A switch having a closure member formed thereon is mounted within the cavity for rotary movement relative to the housing. In a disclosed embodiment the switch has a tab extending through the housing to facilitate rotation of the switch from outside the housing. A flexible, resilient tube in fluid communication with the interior of the fluid collection container has a portion disposed within the cavity and extending between the stop and the closure member of the switch. The tube is configured so that fluid discharged from the lower end of the tube is discharged through an opening in a lower portion of the housing. When the switch is rotated in one direction, the tube is compressed between the stop and the closure member, thereby preventing fluid flow through the tube. When the switch is rotated in the opposite direction, the closure member rotates away from the stop so as to permit the tube to open, thereby permitting fluid flow to be discharged from the fluid collection container through the tube. |
