The present invention relates to a connector (100) for a water system. The connector comprises an inlet connector (105), a connector body and an outlet connector (120) arranged in sequence. The connector body is open-sided so as to form a tundish having an open air gap between the inlet and outlet connectors (105, 120), through which water can fall in use. The connector (100) further comprises a sensor for detecting the presence of water within the connector body.

A monitoring system for monitoring a water level in a plumbing element. The monitoring system has a sensor unit, which includes at least one sensor for detecting a measured value and with the aid of which a water level in a receiving space of the plumbing element may be ascertained. A plumbing element is also provided that comprises a receiving space for accommodating water and at least one water outlet for emptying the water from the receiving space.

An automatic drain system may comprise a drain including a neck defining a drain orifice and a flange extending from the neck. A liquid detection sensor is located on at least one of the neck or the flange. A sink assembly may comprise a sink basin and the drain located in a sink opening formed in the sink basin.

A method and apparatus for monitoring a water level in a basin are disclosed. An automatic refill system includes a level sensor coupled to a refill valve system. The refill valve system has a valve driven by an actuator. The actuator receives a signal from a controller in response to a measured water level. The refill valve system flows water into a basin from a water source until a desired level is reached.
