I have seen many different designs for bell siphons. I was wondering if there was one specific type of bell siphon that is generally known to be the best design. ...the most kinks worked out of it.

So far the best over all design I have seen is provided by Affnan, Rob Torcellini, and TCLynx. Affnan has expanded on Murray Hallam's original design using a venturi on the internal stand pipe to create better suction. Rob introduced a j tube set up under the tank connected to the stand pipe to create additional back pressure - which once broken also expands on the total suction. And TCLynx adds another tidbit of great information: make sure your drain pipe is a larger diameter than your input pipe.

All of these tidbits allow for a slow fill and fast drain but in a manner that drastically reduces the cost of ownership to keep these systems moving.
