You can do one of the following: - Raise the mounting of the water witch. - Use a smaller diameter, or shorter hose
Check valves are designed for preventing instantaneous backflow. Pretty much all of them will eventually leak the water back into the bilge, so you will still cycle, only with a longer period. If you want to go that road, you can install a normally closed valve that opens when the bilge pump comes on. However, this adds complication to the system which is never a good thing. I prefer a small bilge pump (500 gph) with a small diameter (3/8 id) hose to keep the bilge dry, and a larger (2000 gph) one (1-1/2 id) with a higher float switch if more pumping is needed.
