Abstract: A system including a sump having an inner volume and a junction box coupled to the sump. The junction box has a body defining an inner volume, and also has a first inlet and a second inlet, wherein each inlet is in fluid communication with the inner volume of the body. The junction box further has a first outlet and a second outlet, wherein each outlet is in fluid communication with the inner volume of the body such that a first wire is positionable in the first inlet and the first outlet and a second wire is positioned in the second inlet and the second outlet.

Abstract: An overfill prevention valve that is testable to ensure proper functionality of the valve. More particularly, in one embodiment the invention is an overfill prevention valve system including an overfill prevention valve having a blocking component. The blocking component is movable between a closed position, wherein the blocking component generally blocks fluid from flowing through the valve, and an open position, wherein the blocking component generally allows fluid to flow through the valve. The valve further including a float operatively coupled to the blocking component. The system additionally has an actuator that is operable to directly or indirectly move the blocking component to at least one of its open or closed positions to thereby enable testing of the overfill prevention valve.
