Abstract
A drain tool assembly adapted to couple to a housing without causing fluid to flow from the housing until moved to a draining position. The drain tool assembly avoids fluid spillage by sealing a body to the housing and then engaging a plunger of the housing by moving and locking a sleeve to initiate a flow of fluid from the housing.
