Do you think you got lucky in finding the right dimensions/geometry to allow good results for your pump (both during operation and ,perhaps more crucially, at dry startup), or do you think the range of successful flow rates is wide?

Put another way: It must be tough to generate enough flow at startup to flush out all of the air, while still slowing down the ensuing siphon sufficiently to prevent drainage of the box and creating a never ending cycle of dry startups.

You need lots of flow at first, but restricted flow once siphoning.

Again, the system may be quite robust, I just wonder what the limiting flow rates are, especially for a no-worry dry start.

I don't expect you to know, obviously, but what are your thoughts?
