Abstract: A siphon adapter is disclosed. The siphon adapter is comprised of a pipe configured so that one end of the pipe fits inside of a container through the opening and is in very close proximity with the lowest portion of container. The other end of the pipe is outside the container and connected to a shut-off device. It is lower than the first end so that after liquid starts to flow out of the container through the pipe and the shut-off device, the pipe forms a siphon and the liquid continues to flow out of the container even after the level of the liquid is below the opening until substantially all of the liquid has flowed out of the container or the shut-off device is turned off.
