Abstract
A fluid drain apparatus includes a quick drain assembly which may be permanently installed on a fluid tank or receptacle, and a cooperating quickly attachable and releasable connector assembly which mates with the drain assembly. The drain and connector provide for automatic opening of a drain valve within the drain portion of the apparatus, when the connector is removably connected to the drain portion. The connector is automatically retained on the drain portion until release by a mechanic or other person, without requiring continual retaining on the drain portion by the mechanic during the draining operation. A drain hose and portable collection tank may be provided with the drain valve and connector, along with a storage hook for the hose and caps for the tank which preclude leakage from the hose or tank. A suction pump may also be provided to accelerate the fluid flow from the fluid tank being drained. The apparatus is adaptable to virtually any fluid tank or receptacle, but is particularly adapted to use with internal combustion engine oil tanks and the like.
