A liquid siphon for emptying containers such as drums includes a main suction pipe, of a relatively large diameter, and an auxiliary suction pipe, of a relatively small diameter, which auxiliary suction pipe is coextensive with the main suction pipe and extends slightly beyond the main suction pipe.

A liquid siphon for emptying containers such as drums includes a main suction pipe, of a relatively large diameter, and an auxiliary suction pipe, of a relatively small diameter, which auxiliary suction pipe is coextensive with the main suction pipe and extends slightly beyond the main suction pipe. At the location where the siphon is attached to a hose, a stopcock is provided which is used to close the main suction pipe when the siphon begins to draw air so that the auxiliary suction pipe along pulls liquid from the container. In this way residual liquid is removed from the container.
