not running a Herbie full time (just on my 33g QT) but never had a problem with the primary drain restarting, but then it was just a straight vertical pipe coming up from the bottom of the tank.
Could see having a down turned elbow causing a air lock.

Sounds like trapped air to me. How close to the top of your overflow is the valve. It might be that there isn't enough water building up in the pipe after startup to push the air out.

Can you just remove the downturned elbow? If it's there to make your normal drain lower than the emergency drain then it won't work. How about an elbow turned upward on your emergency drain to make it higher instead?

Herbie should just be 2 straight stand pipe.. the emergency being taller than the main drain.. the main drain should be full submerged under water.
(for some reason it didn't upload vertically.. but u get the idea...

Ok, i will get photos tomorrow.. I did not make it vertical through the bottom.. I did it through the side. I didn't read anything that had said I could only do it completely vertically. There are atleast 2 elbows in it.
