5.2 Avoiding siphoning
If there is a height difference ΔH between the suction side and
pressure side container side / system, the low lying line can
develop a suction effect and trigger the siphoning effect be-
tween the communicating containers / systems. This siphoning
effect also occurs when fluid is pumped in a pre-pressurized
reservoir.
