The portable oil drain would have a gave valve on the side to empty by gravity. There is a red knob that you would open to drain. You can also use the air evacuation kit item #145996 to empty the oil drain. There is a 3/4" coupler that you would connect the evacuation kit to and then to an air compressor to suck the oil out into a barrel. We do not have any pictures of the drains.
