Abstract
A drain system and method for draining a first liquid, including a collection vessel having a first chamber arranged to receive the first liquid, a second chamber, and higher and lower valves positioned between the first and second chambers. When the valves are open, liquids can pass between the chambers. When the pressure in the second chamber exceeds that in the first chamber by more than a first predetermined amount, the valves are closed. A first outlet to the second chamber allows liquids to flow from the second chamber. In a first mode, the first inlet supplies a second liquid at a pressure higher than that of the first liquid in the first chamber such that the valves are closed. In a second mode, the first inlet stops supplying the second liquid such that the pressure in the second chamber reduces relative to the first chamber allowing the valves open.
