Abstract

The hand operated pump suitable for unblocking drains has an outer tube (10) inside which is reciprocated an inner tube (1) so that water can be drawn inside by suction. The open end is then placed in contact with the blocked drain or pipe, and pressure built up inside the pump to eject the material which is blocking the drain. An inflatable collar (13) around the open end ensures a good seal between the pump and the drain. The inner tube can also incorporate a relief valve (8) so that liquid can be discharged from the upper end through an extension tube (12).
