A siphon priming device that may be releasably and sealingly connected with a first fluid container and usable to cause a liquid to be transferred from the first container into a second fluid container. Using the properties of the first container one may gently squeeze the container to initiate the siphon then remove the pressure and the siphon continues. The first container may comprise a liquid fuel can and the second container may comprise a fuel tank of a motorized vehicle, e.g., boat, car, ATV, cart, plane, motorcycle, etc. In use, the siphon priming device enables simple, rapid, and safe transfer of liquid fuel from a fuel can into a motorized vehicle.

The present invention relates to a siphon device with a bypass, comprising: a siphon upper section having a top coupling means for connecting to a drain outlet, a side drain opening having coupling means for connecting to a wastewater utility pipe, wherein the siphon upper section is adapted to enable a direct flow via the side drain opening and thereby to bypass a basin of the siphon, thus evacuating substantial volume of accumulated water directly into the wastewater utility pipe.

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.
