Do you know why the siphon water in the tube always seems to want to match the water level?
The same reason that water in a glass is always level. if allowed to flow freely water will always flow to equalize the level throughout the volume even if it is connected by a hose. If you take a long siphon hose and fill it with water and raise the end of the hose, no matter how long it is or how large or small the diameter, the level of the water will always be the same level as the tank level.
Great tool if you are building a deck and don't have a long level to get the support posts all to the same height.
