Siphon tubes are a basic implement used in irrigation to transfer water over a barrier (such as the bank of a raised irrigation canal), using the siphon principle.
At the simplest they consist of a pipe with no working parts. To work they rely on the water level in the canal being at a higher level than the water level in the field being irrigated.
Like any siphon they must be primed (that is, filled with water) before they will start reliably transferring water. However, once primed and positioned correctly, they will continue transferring water from the source to the destination.
