| (54) | Automatic shower tray or wet-room gulley |
| (57) A gulley for a shower tray or wet-room is disclosed which is able to facilitate activation
of a pump for removing waste water from the shower tray or wet-room as required by
the presence or absence of waste water in the gulley. The gulley comprises a chamber
having an inlet for waste water and an outlet for connection to a pump; a magnetic
element; a magnetic sensor; a float; and a confining structure. One of the magnetic
sensor and the magnetic element is arranged in the float. The confining structure
surrounds the float, with the float being freely movable within the confines of the
confining structure. The float is arranged for movement within the confines of the
confining structure so that the relative position of the magnetic sensor and the magnetic
element changes in dependence upon the level of waste water within the chamber. Such
an arrangement is able to provide an automatic gulley which can reliably and rapidly
activate a pump based on the level of waste water in the gulley and which reduces
the likelihood of the mechanism being fouled by local contaminants, hair, scum, and
the like.
