A tool and method clean and drain a water heater tank, removing water and sediment from the tank. An insert tube fits through the hot water outlet port to reach the bottom of the tank interior. A fitting connects the insert tube to a hose extending down the outside of the tank to the floor/ground to a drain or container that is lower than the bottom of the tank interior. After priming the tool by using the cold water inlet flow to fill the tool with water and sediment, the cold water inlet is disconnected from the water heater, venting the tank so that water and sediment are siphoned out of the tank through the tool to empty the tank. The tool and method work without unplugging or disconnecting a clogged water heater drain line, without using a compressor or pump, and without creating a wet, messy environment.

In an ice maker with a sump below an ice formation device and a pump for recirculating water from the sump to the ice formation device, water can drain through a stand pipe drain. A drain fitting is disposed in relation to a stand pipe such that the drain fitting's upper end is disposed above the top of the stand pipe, its lower end defines a water inlet adjacent the bottom of the sump, and its perimeter wall extends 360? about the stand pipe to define a drain passage extending from the water inlet to the top of the stand pipe. The upper end of the drain fitting defines a siphon release opening. The stand pipe drain can also include a valve for adjusting the drain between an overflow drain configuration and a siphon drain configuration.

A siphon is adapted for thoroughly cleaning fluid vessels. The siphon is capable of elevating discharge waste fluid through a transfer of kinetic energy provided by a pressurized fluid source, thereby obviating any need for undesirable electrical, chemical, or other mechanical power sources. An inlet couples pressurized fluid to a divider that splits the pressurized fluid between a jet port outlet and a tank flush source conduit. A siphon return conduit is operative to carry waste fluid from the fluid vessel, with the cleaning attachment protruding from the siphon return conduit. By slightly protruding, the cleaning attachment operatively blocks the siphon return conduit from being held by siphon vacuum against a surface of the fluid vessel while developing a beneficial eddy current flow path. A drain conduit is provided, as is a mixing chamber at a junction between the jet port outlet and an outlet from the siphon return conduit.

A capillary structure for passive, directional fluid transport includes a capillary having a forward direction and a backward direction, the capillary including first and second capillary units each having a sequence of capillary components including a connective section in fluid communication with a diverging section, the diverging section having a forward side and dimensions inducing a concave meniscus in the forward direction, wherein the connective section of the second capillary unit is connected to the forward side of the diverging section of the first capillary unit to form at least one transition section, and wherein a change in the dimensions in the transition section induces in the backward direction a convex liquid meniscus or a straight liquid meniscus with an infinite radius of curvature.

The main purpose in producing this innovative farming machinery is to reduce water, labor, and equipment costs associated with tradition siphon irrigation. Siphon pipes are commonly used in the agricultural industry for row crop irrigation. Traditional harvests involving this irrigation method include corn, beans, tomatoes, and alfalfa, among others. The irrigation method is commonly used throughout the United States, India, and Australia.

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.
