Abstract: Disclosed herein is a device for facilitating siphoning of greywater (graywater) or gently used water. An adapter is designed to fit onto the end of a hose or tube. The adapter is manually held tightly or attached by friction to a spigot or faucet. The faucet is turned on and running water primes the hose. The adapter is then placed under the surface of a collection of greywater in a sink, tub, clothes washer and the like. Greywater is then allowed to flow to a garden, lawn, cistern or other place where the greywater can be put to use instead of shunting it into a sewer. The device includes a funnel-shaped portion and a threaded portion. The device is made from a pliant material such as a silicone rubber or plastic.

Abstract: Apparatuses to enable single-point valve control of siphons, siphon pumps, metering siphon pumps, and turbine siphon pumps include terminal anti-backflow valves, a system flow control valve, a metering chamber, a self-regulating chamber, and a siphon turbine. The terminal anti-backflow valves provide automatically closable systems without further priming after an initial prime. The system flow control valve consolidates functions for priming, pumping, dispensing, and siphon flow regulation to provide single-point valve control. The metering chamber operated by a single-point system flow control valve enables periodic dispensing of liquid above a supply source. The self-regulating chamber controls a single-point system flow control valve to regulate a metering chamber for periodic dispensing. The siphon turbine provided with terminal anti-backflow valves and regulated by a single-point system flow control valve enables hydropower production.

Abstract: A suction pump coupler for replacement of the immersible one-way valve with the pump coupler securable to the inlet end of a suction pump for forming a leakproof connection to an intake pipe to enable use of the suction pump in a location wherein the suction pump is remote from the fluid being pumped with the pump coupler operable for securing an inlet pipe to the suction pump in a leakproof condition through rotational engagement of pump coupler with respect to the inlet pipe even with the presence of the suction pump cantileverly mounted thereon.

Abstract: A siphon initiating device is provided having a cylinder member and slideably interactive hollow piston member, both members equipped with check valves to permit unidirectional flow. Both extremities of the device have threaded fittings for engaging garden hoses. By way of hand manipulated back-and-forth motion of the piston member within the cylinder member, a pumping action is initiated which fills the hoses with water, thereby initiating gravity flow of water through the hoses and initiating device.

Abstract: A water filter including an inlet assembly which comprises a prefiltering foam tip. The inlet hose includes an adjustable float and a weight on the end of the hose which allows a given length at the end of the inlet hose to extend below the surface of the water being filtered. The water filter further includes a check valve assembly to relieve pressure buildup inside the pump. A unique lever-action handle, in combination with a rocking piston, allows efficient filtering with few moving parts. The filter components are easily replaceable. The main filter assembly is suspended resiliently at its periphery to provide shock-absorbing characteristics. The filter also includes an adaptor base which allows for a direct connect between the vessel into which water is filter. The water filter also provides a unique method of storing the inlet hose to render the water filter easy to carry and prevent foreign objects and debris from entering into the area of working parts.

Abstract: A hand held and hand operated device is capable of pumping or siphoning a liquid. The device includes a pair of telescoping hollow tubes having a single longitudinal axis with a seal therebetween that is maintained when one of the tubes is reciprocated relative to the other. Each of the tubes has a conical valve seat at its distal end with each conical valve seat having the same selected angle to the single longitudinal axis of the tubes. Each seat has a separate stainless steel ball to seal on the seat whenever the longitudinal axis of the tubes is at a greater angle to the horizontal than the selected angle of each conical seat to the longitudinal axis. In this position, reciprocation of the tubes causes pumping of the liquid through alternatively removing each of the balls from its seat due to pressure differentials created by changing the volume within the tubes between the balls.

Abstract: A combination vacuum lift pump and siphon for handling liquids, comprising a pump cylinder having an inlet disposed near one end and an outlet adjacent to but spaced from the other end, a piston reciprocatable in the cylinder, and a plunger and handle connected therewith, and a pair of check valves, one of which is associated with the piston and is operable to be closed when the plunger is lifted in the cylinder, and the other of which is disposed at the cylinder inlet and is operable to be closed when the plunger is lowered in the cylinder. The outlet of the cylinder is spaced a short distance from the upper end thereof, such that for siphon operation the piston and its check valve can be moved to a position in the cylinder which is beyond the location of the outlet. Accordingly, the flow of liquid by-passes the piston check valve completely, and the latter thus does not act in such a manner as to restrict the siphon flow, as was the case in many other constructions.

Abstract: A flexible tube liquid transfer device is provided, formed of three concentric flexible tubes to be used as a siphon. A coupling bush connects the inlet ends of the innermost and outermost tubes, sealing the outermost tube to permit liquid to flow into the innermost tube only, through the inlet. An elastic sealing member slidingly seals the middle tube to the outermost tube so that the middle tube can slide relative to the structure comprising the coupled together outermost and innermost tubes. A removable closure seals the outlet end of the middle tube.To start the flow of liquid through the device, one need only slide the middle tube out of the assembly, wait until liquid is drawn up into the assembly by the partial vacuum thereby created, and open the closure at the end of the middle tube while holding the end of the middle tube below the liquid level in the liquid container. In this way, liquid will siphon out of the container without the need of pumps or other devices to start the liquid flowing.

Abstract: A simply constructed and inexpensive syphon for rapidly lifting liquid out of a container, the syphon consisting of a flexible plastic tube in which there is a spongy plastic piston attached to a flexible cord which extends out of one end of the tube so it can be manually pulled whereby liquid is pulled into the tube behind it.
