A system that moves water to a vessel on a water body includes a retractable tube with water intake that descends to a selectable depth in the water body, a pump that moves water from the selectable depth through the retractable tube, an anchor assembly carrying the pump or retractable tube to the selectable depth and back again, and an indicator of the depth of the anchor assembly, pump, or water intake of the retractable tube in the water body. The anchor assembly includes a pole, a cantilever beam, a telescoping pole, a pole driving system, or a combination thereof. The system may include a gas delivery system configured to introduce a gas into the system's water flow and a mixing chamber or tube that mixes water and gas. Variations of the system provide a subset of these components, and can be combined with third-party components.

Provided is a chemical injection system for connection to a chemical tank and a process line. The system includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

A blade assembly is provided that includes a base portion that is removably coupleable to a blender base and an aperture extending through the base portion. The blade assembly further includes a drive shaft rotatably coupled to the base portion, the drive shaft extending through the aperture and rotatable about a rotational axis. The blade assembly further includes one or more blades fixedly coupled to the drive shaft and a coupling member for removably coupling a container to the blade assembly. The blade assembly further includes a guard member extending from the base portion such that the guard member circumscribes the one or more blades about the rotational axis. Further, the guard member circumscribes a portion of the container about the rotational axis when the container is removably coupled to the coupling member.

A sparkling water mixing assembly and a refrigerator having same. The sparkling water mixing assembly comprises a supply module, a mixing container, and a mixing connector. The supply module is configured to supply carbon dioxide. The mixing container is configured to contain a liquid to be mixed, and has an opening. The mixing connector is configured to enable the mixing container to be detachably disposed thereon. The mixing connector has a mixing chamber, a pressure channel, and an accessing channel. The mixing chamber allows the opening to extend into the mixing chamber. The pressure channel is communicated with the mixing chamber, and is configured to adjust the pressure in the mixing chamber. The accessing channel is communicated with the mixing chamber and the supply module, and is configured to enable the mixing container to obtain carbon dioxide.
