PUMPED DRAINAGE APPARATUS

摘要

Pumped drainage apparatus (10) for a shower, comprises a waste water unit (12) having a waste water inlet (14) for accepting waste water runoff from a shower, and a waste water outlet (16) in fluid communication with the waste water inlet (14); a pump (20) in fluid communication with the waste water unit (12); a sensing circuit including one or more sensors (36) for sensing waste water; and a control circuit for controlling and varying a flow rate of the pump (20) based on an output of the sensing circuit. Preferably, the or each sensor is isolated to prevent in use contact with waste water. A variable flow control device (34) is also provided.
