Endoscope cleaning station having leak tester and high-pressure port

A method of cleaning an endoscope, the method comprising:

• providing an endoscope cleaning station that includes a sink having an inlet connected to a water supply for filling the sink and a drain for draining the sink;
• controlling a flow of water to the inlet of the sink using a fill solenoid;
• selectively dispensing detergent into another flow of water thus creating a detergent solution using a detergent pump and detergent valve;
• injecting the detergent solution into the endoscope using a manifold;
• controlling the flow of the detergent solution to the manifold using a lumen solenoid;
• reducing a pressure of the detergent solution delivered to the manifold using a pressure regulator disposed downstream of the lumen solenoid and upstream of the manifold;
• and
• cleaning a narrow channel of the endoscope using a high-pressure port configured to be connected to the narrow channel by receiving the detergent solution at the high-pressure port that bypasses the pressure regulator so that the detergent solution exiting the high-pressure port into the narrow channel has a higher pressure than the pressure of the detergent solution delivered to the manifold.
