A simple 1" pvc pipe with holes drilled in it and a bilge pump hanging in the water. Run a deep cycle battery with a mechanical timer and a solar panel on the side of the jump. We seldom wax our show jump, but it would be good maintenance. Also buy some seagull detractors to keep excrement off the jump. How deep of water will it be in? You will need 4 anchor lines , 2 criss crossed in front and back.
