A medical device includes a one-way flow valve in communication with fluid to be drained. The valve is connected to a primary distribution plate which has a raised perimeter with at least one opening in the perimeter. There is a secondary distribution plate having a raised perimeter with at least one opening in the perimeter. At least one pair of plugs, each having a central passageway, are inserted into the openings in the perimeters of the primary and secondary distribution plates, and an connecting tube places the primary and secondary distribution plates in fluid communication with each other. The tube is sized to fit inside the central passageway of the plugs, with the connecting tube having opposed ends, each end inserted to the passageway in the plugs. The distance between the plugs is adjusted by sliding the plugs along the length of the connecting tube.
