Break the siphon instantly & reliably every time. I normally explain why I'm against check valves, but using it backwards is an entirely different story. If you have separate returns, you may need to use one for each one. If you simply use locline, anti-siphon holes are ideal but if you use penductors, the back pressure works against them in a bad way. Instead, the reversed check valve is the solution.
