Abstract: The specification discloses a closed system for cleaning, pressure testing, and drying fire extinguisher containers. The system comprises two tanks for holding trichloroethane and flow lines and a valve control system for flowing the liquid from one tank into the container to be cleaned, pressure tested, and dried and then from the container to the other tank. After a number of containers are cleaned and pressure tested and the second tank becomes full, the valve control system can be controlled to reverse the flow of liquid from the second tank to the containers to be cleaned, pressure tested, and dried and then back to the first tank.In a further embodiment, there is provided a universal head adapted to fit many different sizes of fire extinguisher container openings and in addition an adjustable holding device for holding the container to be tested between a support plate and the head and for inverting the container to allow the container to be emptied after the test is completed.
