There is some confusion of what constitutes a siphon system and a bottom draw system.
You can have a bottom draw type overflow without it being a siphon system and you can have a conventional pipe overflow that goes into siphon mode. I have the latter.
But most people seem to lump the two terms of siphon and bottom draw together as if they are mutual. They are not. They are two independant attributes that are often combined in a system but can also be exclusive.
