I've seen it done. However, submersible bilge pumps already suffer a
substantial drop in performance when they have to lift water up--the higher
the lift the greater the loss, which is much greater in a centrifugal pump
than, say, a diaphragm pump. A check valve adds more "friction" to an
already "lossy" system. Still, many boats have an in-line check valve to
prevent reverse siphoning when heeled over.
