You can route the discharge piping to a level above the discharge connection from the hull and do it well before the discharge line gets to the discharge connection from the hull. From its high point it could be self-draining outward to the discharge connection. By doing this it minimizes the amount of bilge water that will flow back into the bilge when the pump shuts off.
I would not use a check valve in the bilge discharge line because it is the last place you want a line blockage.
