Abstract
A conduit (51) for a condensate removal pump is disclosed comprising a tubular member (47) having a profiled rim (53, 54) at a distal end, profiled such that only a portion of the rim lies in a plane located at the extreme distal end of the tubular member perpendicular to the axis of the tubular. A resilient membrane (52) which has a slit extends across the interior of the tubular member and is arranged to open, to allow water to pass, when water is drawn through the conduit. A combined sensor and suction tube assembly (50) is also disclosed comprising a tube (55), a self heating thermistor (56) coupled to the tube, and a relay means (69) to relay an operational parameter of the self heating thermistor, indicative of the presence of water, to a condensate removal pump. The combined sensor and suction tube assembly is sized to fit within a pipe having an inner diameter of 20 mm.
