METHOD OF PRIMING A DRAINAGE APPARATUS FOR SIPHONING LIQUID AND DRAINAGE APPARATUS
A drainage apparatus (100, 300-800) for siphoning liquid between first and second reservoirs (102, 104) is disclosed. In a first embodiment, the apparatus (100) includes a conduit arrangement having a first opening (112) disposed in the first reservoir (102), a second opening (114) disposed in the second reservoir (104) and a liquid injection inlet (106M2) arranged between the first and second openings (112,114), and a plurality of valves (108, 110) for controlling flow of the liquid along the conduit arrangement. A method (200) for priming the drainage apparatus (100) comprises directing liquid into the conduit arrangement at (202) via the liquid injection inlet (106M2) to fill up most of the conduit arrangement as controlled by the valves' configuration; directing liquid into the first reservoir (102) to enable more liquid to enter into the conduit arrangement via the first opening (112) 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 to prime the conduit arrangement. After the priming and in use, the siphon is triggered when more liquid is added into the first reservoir (102) which causes the added liquid to be siphoned to the second reservoir (104) via the primed conduit arrangement.
