Herbie drain is a pain

That article says to run both the siphon and emergency lines under water into the sump, which allows it to go full siphon if it has to. Makes sense I guess. I just hope I can do it without bringing the DT level too high, I'll monkey around with it tonight.

Put a ball valve on the return, turned the flow down about 10%. Raised the level in the overflow to about 1/8" below the emergency drain. I only have about 1/4" of the weir showing above the surface but it still skims the top so it's good to go. I guess now we wait and see .
