The automated gray water system comprises a three port diverter valve and a wireless switch controller. The three port diverter diverts gray water collected within a building from a first port to a second port when an internal mechanism of the valve is in a first valve position and from the first port to a third port when the internal mechanism of the value is in a second valve position. In the first valve position, gray water is passed to a water purification and/or storage system and may be used as a non-potable resource. As a non-limiting example, the gray water may be used for landscape irrigation. In the second valve position, the gray water is passed to a public sewer system or septic system. The position of the valve may be controlled from a smart device via a wireless link to the wireless switch controller.

An opening/closing device according to the present invention includes a gate, a fall prevention unit, a support release unit, a first float, a floating prevention unit, a second float, and a floating prevention release unit. The gate receives a flow of fluid, and is able to fall down toward a downstream direction of the flow. The fall prevention unit supports the gate, thereby preventing the gate from falling down. The support release unit releases the support for the gate by the fall prevention unit. The first float is arranged on an upstream side of the gate, is arranged on one of the left side and the right side of the gate viewed from upstream, and is less in the specific gravity than the fluid. The floating prevention unit prevents the first float from floating.

Single-door flap gates and double-door flap gates are disclosed. Flap gates of the inventive subject matter are coupled with a structural element by one or more linkages, where hinges that are coupled with the structural element allow flap gate doors to open when sufficient fluid build-up exists behind the doors to push the doors open. Hinges are mounted at an angle. Features to facilitate fluid drainage despite the flap gate doors being closed are also contemplated.

The present disclosure relates to a device for preventing access to a conduit. The device comprises top and bottom compression plates and a compressible member between the compression plates. A bolt has a first end mounted to the bottom compression plate and a shaft passing through openings of the compressible member and of the top compression plate. The bolt has a head proximate its second end. The head of the bolt extends beyond a major diameter of the threaded shaft. At least a portion of the shaft is a threaded shaft. The head of the bolt prevents a nut mounted on the threaded shaft between the head and the top compression plate from being dismounted from the device. A fluid passage may extend in the compressible member between the top and bottom compression plates to allow a fluid to bypass the device.

A system, device, and method for communicating distress signals through a plumbing control system is provided. The system includes a plumbing controller configured to operate at least one plumbing appliance, at least one distress indicator in communication with the plumbing controller, and at least one distress sensor in communication with the plumbing controller. Activation of the at least one distress sensor causes activation of the at least one distress indicator.

Disclosed herein, are gravity-based sewer bypass systems and related methods for diverting sewage fluid from an upstream sewer pit to a discharge site lower than the upstream sewer pit, via a pipe including an above-ground portion. A sensor external to the pipe is used to determine the sewage fluid level in the upstream sewer pit and accordingly regulate the outflow of sewage fluid at the discharge site.
