My primary plan is in the jpeg but is a lot more work, and its only advantages that I can see are that it has an auto siphon function that MIGHT speed draw down after a big rain, it has a mechanism for stopping the siphon when it occurs, and it may be less susceptible to damage of the vertical pipe by broken supports or tree limbs.
