A good treadle pump satisfies many user criteria including some that can be tested under laboratory conditions. The paper describes a set of laboratory tests and suggests performance thresholds that should be reached in them. The tests relate either to efficiency or to ease of priming. Under the description of priming tests there is included an analysis of the effect of any 'dead volume' of trapped air upon the maximum suction head of a pump during priming and during steady operation.
