Patent ID: 10392792

Abstract:
A method 200 for priming a drainage apparatus 100 comprises directing liquid into the conduit arrangement at 202 via the liquid injection inlet 106b12 to fill up most of the conduit arrangement as controlled by the valves' configuration; directing liquid into the first reservoir 102 at 206 to enable more liquid to enter into the conduit arrangement via the first opening 112 and at 208, to flood the conduit arrangement to form a continuous liquid flow path which extends from the first opening 112 up to at least the second opening 114, the continuous liquid flow path creating a siphon; and with the first opening 112 kept below the liquid's surface level in the first reservoir 102, stopping the flow of liquid into the first reservoir 102 to achieve a state of equilibrium of the siphon at 210 to prime the conduit arrangement.
