A float unit pump comprises a riser pipe 10 configured to raise water. A constriction 14 at a constriction location 12 constricts the flow of water in the riser pipe 10, the water having a first pressure at an un-constricted portion of the pipe immediately below the constriction location 12, and a second pressure at the constriction location 12. A second pipe 20 supplies floats 24 for insertion into the riser pipe 10 at the constriction location 12, the floats 24 configured to cause an upward flow of water in the riser pipe 10. In use, floats 24 supplied from the second pipe 20 enter the riser pipe 10 at a point, where the water in the riser pipe 10 has a lower pressure than the first pressure.
