Abstract: The wait water collection system provided herein may be used to reducing the amount of water wasted while a shower, for example, warms up. The wait water collection system may include a hot water input carrying hot water to the system. The hot water may or may not be “hot” when delivered by the hot water input and may need to “warm up.” The wait water collection system may include a thermal diverter on a water line where the hot water travels, which may adjust based on whether the temperature of the hot water meets a temperature threshold. If the water does not meet the temperature threshold, then the hot water may be delivered to an expansion vessel. If the water meets or exceeds the temperature threshold, then the hot water may be delivered to a mixer valve for providing the water to a user.

Abstract: A low water consumption showerhead may provide users with the experience of higher water pressure without necessarily requiring an increased supply of water. A first example showerhead may include nozzles having coaxial inner and outer chambers, each of which may provide a user with one or more different types of media. The inner chamber of the nozzle may be adjustable with respect to the outer chamber, which may allow a user to manipulate the relative rate of flow from both chambers. A second example showerhead may include a spiral channel along which one or more types of media may flow. Outlets may be positioned along the spiral channel such that a portion of the media within the spiral channel may exit the showerhead and be directed to a user. The width or area of the spiral channel may taper such that substantially consistent pressure may be provided at each outlet.

Abstract: Provided herein is a point of use heating showerhead. The showerhead may comprise a feed pipe coupled to a water input, a waterway connected at a first end to the feed pipe, and a sprayplate connected to a second end of the waterway. Water may flow into the feed pipe via the water input. Water may flow into the waterway via the feed pipe. Water may be heated via the heating element in the waterway. Heated water may exit the showerhead via the sprayplate.

Abstract: A plumbing fixture includes a water passage configured to hold water, a first plate shaped according to a cross section of the water passage and spaced at a first distance from the water passage, and a second plate shaped according to the cross section of the water passage and spaced at a second distance from the water passage. A voltage between the first plate and the second plate is generated based on the water in the water passage.

Abstract: Provided herein is a showerhead that may include inlets, inlet channels, and nozzles. The inlets may provide different media to the showerhead. The inlet channels may be connected to the inlets, such that the media flowing into the inlets flows through the inlet channels. The nozzles may include outlet channels, each of which are operably coupled to one of the inlet channels. As one example, the inlets may provide a first media (air) and a second media (water). When the first media mixes with the second media into an output, the flow rate of the output is greater than the flow rate of the second media. Even when a decreased water flow rate is used, a user perceives a high flow rate due to the introduction of air into the water.

Abstract: A venturi is provided herein that includes a tubular passageway, a pod, a first entry point, and a second entry point. The pod may be positioned and contained within the tubular passageway. The first entry point may introduce a first media into the venturi, and a second entry point may introduce a second media into the venturi. The first media and second media may be any media, including fluid or gas. The first media may mix with the second media to develop a mixed media, and the mixed media may flow around the pod. The pod may translate axially within the tubular passageway via a translation rod and a spring. The spring may cause the pod to translate axially based on a pressure of the fluid entering the venturi.

Abstract: The present disclosure relates to a recirculating shower system. The recirculating shower system may include a first shower outlet and a second shower outlet. The recirculating shower system may include a fresh water conduit fluidly coupled to the first shower outlet and a recirculated fluid conduit fluidly coupled to the second shower outlet. The fresh water conduit and the recirculated fluid conduit may be arranged such that warmer fresh water flowing through the fresh water conduit may heat cooler recirculated fluid flowing through the recirculated fluid conduit.
