A jet pump including a housing having a central longitudinal bore and at least one longitudinal return bore, the central bore is in fluid communication with the return bore. A nozzle is disposed in the central bore in fluid communication with a mixing section. A chamber is formed within the central bore proximate the nozzle and the mixing section. A production inlet port is formed radially through the housing between the chamber and the exterior of the housing. The top of the housing is adapted for connecting a conduit for providing the motive or power fluid to the central bore and the carried nozzle and for returning the mixed motive and production fluid from the return bore to the surface. The jet pump may further include a check valve mechanism positioned in the production inlet ports. The check valve mechanism allowing fluid flow through the port from the exterior of the housing into the central bore and substantially blocking flow through the port directed from the central bore to the exterior of the housing.
