Patent abstract
A pumped shower draining device for a shower installation, comprises a housing having a waste water inlet and a waste water outlet, a pump element provided within the housing, a pump driving device for driving the pump element, and a variable-engagement clutch for providing variable driving engagement between the pump driving device and the pump element. An amount of engagement imparted by the in use clutch is determined by an amount of waste water flowing from a shower unit of the shower installation. Preferably, the clutch is self-regulating, so that the amount of engagement is determined by an amount of water in or at the clutch.
