Conduit for a condensation removal pump

A condensate removal system including a combined sensor and suction tube assembly, the combined sensor and suction tube assembly comprising:

• a tube having a proximal end which is arranged to be connected to the inlet of a condensate removal pump and a distal end which is arranged so that water may be drawn through the tube,
• a first and second self heating thermistors coupled to the tube,
• a cylindrical housing within which the tube and the self heating thermistors are located, and
• a relay means which is arranged to relay an operational parameter of the self heating thermistors indicative of the presence of water to the condensate removal pump, wherein the tube and the self heating thermistors are connected to the cylindrical housing,
• the cylindrical housing surrounding said tube and defining an open chamber adjacent to said tube to hold said self heating thermistors, and
• wherein the combined sensor and suction tube assembly is sized to fit within a pipe having an inner diameter of no more than 20mm.
