A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.

A connector assembly for fluid filter elements is provided comprising first and second connector elements each comprising at least two connector snap arches, each of the connector snap arches including a snap tooth lock; and at least two connector snap arms, each of the connector snap arms including a snap tooth; each connector element having a central opening, and an annular channel for receiving an end of a hollow cylindrical filter element; a gasket arranged between the first connector element and the second connector element, the gasket having a central opening; wherein the first connector element and the second connector element are lockably engageable with each other when placed in contact with each other and axial force is applied such that respective connector snap tooth is retained in each respective connector snap tooth.

Various examples are provided for smart water systems. In one example, a method for providing water through a faucet includes detecting a voice request from a user; providing an indication of the voice request to control circuitry of an electrically operated valve coupled to a water supply line of the faucet; and activating the electrically operated valve to provide water through the faucet. In another example, a method includes detecting a request for water from a user; providing an indication of the request to control circuitry of an electrically operated valve coupled to a water supply line of the faucet; and activating the electrically operated valve to provide a specified amount of water through the faucet.

The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.

A fluid purification system capable of removing lead from significant volumes of fluids also containing at least one of TOC and TTHM under low pressure conditions and at reasonable flow rates is provided. The system comprises a first fluid purification media comprising a rigid porous purification block. The rigid purification block includes a longitudinal first surface; a longitudinal second surface disposed inside the longitudinal first surface; and a porous high density polymer disposed between the longitudinal first surface and the longitudinal second surface. The system further includes a second fluid purification media, comprising a fibrous, nonwoven fabric disposed adjacent to the first surface of the first fluid purification media, the second surface of the first purification media, or both.
