Abstract
A liquid drainage system for a sanitary installation has a liquid level sensor for detecting the level of liquid in a drainage receptacle. The sensor employs non-contact sensing, for example an electric field, to detect the liquid level and controls the operating of a drainage pump depending on the detected liquid level. The drainage receptacle may for example be the gulley of a shower tray, or a manifold connected to two or more sinks.
