    This is my full siphon on Synergy overflow. Is anyone running a flow sensor on their full siphon line? It seems no matter how closed down my gate valve is, I get sharp drops in flow. No air is making it into the lines, I have a steady trickle on the secondary drain line.

    I am not running full siphon on my return, but this makes sense to me. It's not really sharp drops, its only 5% or so, and when I watch my siphon over time, I see occasional fluctuations, like the pressure in the return is building building building, slows for a second or two, then releases back out. I think this is because my return pump and return flow is not matched 100%, if this makes sense.
