  • Publication number: 20080213101
    Abstract: A control device (10) for controlling a shower waste pump, comprises a housing (12) which is mountable to a supporting surface, pump setting means (14) located in and/or on the housing (12), and over-run setting means (16) located in and/or on the housing (12). The pump setting means (14), by way of a control element, preferably a manually adjustable potentiometer (42), allows selective setting of a maximum pumping capacity of the waste pump. The over-run setting means (16), also by way of a control element (48), allows selective setting of an over-run period from a predetermined range during which the waste pump continues to operate after fluid flow through the waste pump has ceased or substantially ceased. The over-run setting means (16) and the pump setting means (14) together can optimise operation of the waste pump, so that the over-run period of the waste pump can be set based on the selected maximum pumping capacity.
