Apparatuses, systems, and methods are disclosed for fluid flow control. A container is shaped to receive a liquid, and includes an outlet configured to allow the liquid to exit the container. The outlet may be user-adjustable to adjust a rate at which the liquid exits the container. A valve is configured to control a fluid flow based on a liquid level in the container. An output line coupled to the valve is configured to convey the fluid flow from the valve to a location outside the container. The location outside the container does not receive the liquid directly from the outlet.

A liquid reservoir for use in a toilet seat assembly having a presence sensor configured to detect a presence of a user includes a housing, a heating member, a temperature sensor, and a level sensor. The housing has a base portion, a cover portion, an inlet, and an outlet, and the housing is configured to contain a liquid. The temperature sensor is configured to detect a temperature of liquid within the housing. The level sensor is configured to detect an amount of the liquid within the housing. The heating member is configured to heat the liquid contained in the housing upon the presence sensor of the toilet seat assembly detecting the presence of the user.

A float valve (10) is provided for use with a liquid medium, the float valve having an upright configuration and an inverted configuration. The float valve includes: a housing (12), defining at least one inlet port (20) and at least one outlet port (24); a float assembly (60) movable within the housing; and an auxiliary float member (50) movable within said housing. The float assembly (60) comprises a primary float member (70; 70′), different from the auxiliary float member, and a spring element (80). The primary in float member is configured for closing the at least one outlet port when in abutment therewith, the spring element being configured for providing a biasing spring force to the primary float member in a direction towards said at least one outlet port. The auxiliary float member is configured for providing a net upthrust force with respect to the liquid medium under submerged conditions irrespective of whether the float valve is in said upright configuration or in said inverted configuration.

An appliance includes an appliance unit having a housing with the housing having steam emission holes, a heater in the housing, a primary water tank in the housing, and a cradle that is removably connectable to the appliance unit. The cradle has a secondary water tank that can communicate with the primary water tank when the appliance unit is connected to the cradle.

A liquid level control system, which may be used with a clarifier in a sewage treatment plant, manages liquid level of an upstream basin by controlling liquid flow in or out of a system that may use a midstream device to equally distribute flow in or out of the basin. This headloss inducing device creates a non-linear relationship between upstream liquid level to be controlled and the lesser downstream liquid level behind the gate or valve. Without the use of electrical controls, the systems of the invention include a gate or valve with counterforces that manage the outflow stream of liquid while accounting for the non-linear head loss created by the midstream device, thus reaching a desired liquid level range for all system flowrates.

A pivotable downspout extension system includes an adapter coupleable to a fixed-position downspout via a downspout aperture, a bucket hingedly coupleable to the adapter, and an extension arm. The extension arm is received by an extension arm receiving portion located on the bucket. The bucket and the extension arm remain in a substantially vertical position until a sufficient amount of water enters the bucket so as to overcome the weight of a weight chamber of the bucket and move the bucket's center of gravity. The bucket with the extension arm then pivots on a fulcrum point, allowing the water to exit the extension arm. Once emptied, the weight chamber of the bucket pivots the bucket and extension arm to the substantially vertical position.
