  • Patent number: 8403647
    Abstract: A control device for controlling a shower waste pump, includes a housing, a pump setting, and an over-run setting. The pump setting, by way of a control element, preferably a manually adjustable potentiometer, allows selective setting of a maximum pumping capacity of the waste pump. The over-run setting, also by way of a control element, 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 and the pump setting together optimize 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.
