Abstract
There is provided a water supply control system for a tap (2). The control system includes a spindle (16) attached at one end to a tap handle (10) and at its other end to a tap rotation detector/valve actuator, the spindle (16) extending through the water supply conduit (3) to a tap rotation detector (5) which sends a signal to a supply valve (4) via a controller (6). The controller (6) triggers closure of the valve (4) if the valve has remained open for a predetermined time interval. The control system also has a detent to limit rotation of the spindle (16) in a tap closing direction.
Claims12
A water supply control system for use with a water tap, the water supply control system comprising:
- a spindle arrangement adapted for exposure to water during use, the spindle arrangement incorporating a spindle having a first end, a second end and a portion intermediate the first and second ends, the first end region of the spindle being adapted for rotation with a water tap handle and including means for connection to the handle of a water tap;
- a tap rotation detector adapted to identify the direction of rotation of the spindle remote from said first end region;
- a valve adapted to control the flow of water to the water tap;
- and
- a controller in communication with the tap rotation detector and the valve, wherein the controller is adapted to trigger closure of the valve when the valve has remained open for a predetermined time interval,
- the water supply control system further comprising a detent adapted to limit rotation of the spindle in a tap closing direction.
