An apparatus and method for an intake-end siphon flow regulator that allows for continuous operation in container liquids with entrained gases. A float actuated valve opens and closes as needed so that the siphon draws in container liquid. The float valve mechanism uses magnets that provide for a continuous valve cycling. This cycling overcomes gas build up that typically causes the siphon to fail. By disallowing extended periods of relatively low flow and pressure, the siphon builds up less gas bubbles that obstruct siphon operation. When the liquid rises enough, the float's buoyancy overcomes the magnetic attraction and the valve completely opens. The highest flow possible occurs and washes gases downstream. As the container liquid draws down, the magnets draw closer and when their magnetic fields interact, the magnets are drawn together, completely closing the valve. As liquid again enters the container, the aforementioned cycle repeats.

A withdrawal system (1) for a container (2) and comprises an immersion pipe (4) mounted on and projecting into the container (2) as well as a withdrawal head (5) that is attachable to the immersion pipe (4) by means of a rotary connection. The withdrawal head (5) attached to the immersion pipe (4) is secured by means of a mechanical locking unit.
