Abstract
A pump assembly and method is disclosed comprising, a pump including a pump housing having a fluid inlet and at least one fluid outlet extending from the pump housing. A magnetic body of a brushless DC motor is submerged in the fluid and drives an impeller that moves the fluid from the fluid inlet to the at least one fluid outlet. A valve rotatably mounted between the impeller and the at least one fluid outlet selectively directs the flow of fluid through the at least one fluid outlet.
