When installing siphons, what is a critical installation requirement?

The requirement for siphons to be level and primed with water is essential for their proper functioning. Siphons rely on gravity and the difference in height between the inlet and outlet to move liquid. If a siphon is not installed level, it may not create the necessary pressure differential to initiate and sustain the flow, potentially resulting in improper operation or failure to siphon at all.

Priming the siphon with water is equally critical because, without water in the siphon tube, there can be no continuous flow. Air pockets can disrupt the siphoning action, leading to air breaks that prevent the siphon from working effectively. Therefore, achieving a level installation and ensuring it is primed with water are fundamental to the successful operation of a siphon in any septic system.
