The invention relates to a method for draining water from a tank (22), more particularly a clarification tank, wherein water is optionally drained via a draining apparatus while maintaining a substantially constant liquid level (23).

A liquid sampler is provided for collecting a sample of a liquid, the liquid sampler comprising: a tube which includes a proximal end and a distal end, and a bore therebetween; a resilient member which is removably housed in the bore; a first plug which is attached to a distal end of the resilient member; at least a second plug which is attached to the resilient member, proximally to the first plug; and a grip which is attached to a second end of the resilient member, wherein one or more of the second plug and grip extend outward from the distal end and the proximal end respectively, in use.

Embodiments of the present invention are directed to a water pumping system. More specifically, embodiments of the present invention are directed to a solar electric powered, siphon-capable water pumping systems specifically configured for use in rooftop and other applications having similar need and conditions. Advantageously, a water pumping system configured in accordance with an embodiment of the present invention is configured to prevent pooling of water in low-lying areas of a roof and thereby limits the potential for damage to the roof and underlying structure that could otherwise result from such pooling of the water.

Systems, devices, and methods for a one-time disposable device arrangement for dispersing liquids of varying viscosities, or their constituents, in a metered manner over a definable period of time. The invention employs a flexible reservoir, of varying size, shape, and configuration, along with a calculated, finite length of looped flexible tubing, one of varying size, shape and configuration. The device arrangement can be hung over an area where it is desired to attract animals such as deer by dispensing liquids, such as but not limited to animal attractants, such as deer urine and buck jam, and the like.

A siphon includes a feed area for feeding a liquid, a downpipe connecting to the feed area, extended from top to bottom in a use position of the siphon, a deflection pipe filled with liquid during stationary operation on the end of the downpipe facing away from the feed area connecting to this, a riser pipe on the end of the deflection pipe facing away from the downpipe, and connecting to this, extended from bottom to top in the use position, and a discharge area connecting to the end of the riser pipe facing away from the deflection pipe for discharging liquid. A storage tank arranged on the siphon between the feed area and the discharge area is hydraulically connected to the deflection pipe and designed to automatically fill with liquid during stationary operation and to automatically empty into the deflection pipe following a pressure surge affecting the siphon.

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.

Two or more siphon pipes positioned in successively-higher containers of water to raise water or other liquids up higher than the maximum 10-meter rise for a single siphon by means of the successively-higher containers each holding a bell-shaped, open-bottom structure which will capture a bubble of air and prevent the air bubble from rising to the top of the water surface, and each of which is about ten meters higher than the previous container, without pumping the water or other liquid with a water pump.
