A leak-tight rotatable plug valve for controlling water flow to and from a fish livewell in a fishing boat. The valve body has opposite ends connected with an inlet hose for fresh water intake and a drain hose extending from the livewell drain. A pump inlet passage in the valve body intersects with the valve flow passage and mounts a pump having its discharge connected with a supply hose leading to the livewell. When the valve is open, fresh water can be pumped to fill the livewell when the pump is active and the livewell can be drained when the pump is inactive. When the valve is closed, the pump recirculates water through the drain hose and supply hose to avoid stagnation and provide aeration for the livewell.
