Hi Greg, that’s scary about a blockage! What happened, did you have a strainer at the time? What clogged it? Mine “seems” (knock on wood) to be fine so far. The only thing I have noticed is the small hose for the siphon break has got plugged, so I just cleaned it out. Other than that mind has worked well with the strainer and the standpipe for emergency.

As a general rule, I think the classification of the Herbie method always incorporates an emergency standpipe; without the emergency standpipe, it would be called the "Flooding is Guaranteed Method".

I think what Harvie is asking if a standpipe is required on the primary drain in which case IME the answer is no. I close the gate valve until the water level is just slightly lower than the emergency standpipe - this minimizes the waterfall noise into the overflow.
