Controller for a manifold assembly in a water filter system
A control system for a water filter assembly comprising a filter having an RFID tag and an RFID sensor to generate a RFID signal containing data related to the filter. A valve assembly moves between a shut off position, an operational position directing the flowpath of the water supply through the filter, and a bypass position. A controller communicate with a lawn irrigation system to determine if the irrigation system is operative. When operative, the controller has the valve assembly switch to the bypass position. The controller also receives the RFID signal to verify if the filter is proper. The controller also receives a leak signal from a leak sensor and has the valve assembly automatically switch to the shut off position if a leak occurs. The controller can name the leak sensor with a location and indicate battery life of the leak sensor.

An intelligent roof drain system includes a roof drain surrounded by a drain plate. A water seepage detection module is disposed proximate the drain plate. The water seepage detection module includes water seepage detection sensors and circuitry and an antenna system to inductively receive power and communicate water seepage data. A roofing membrane is disposed over the water seepage detection module. A monitoring module that includes control circuitry, power supply circuitry, water level detection circuitry, communications interface circuitry, and an antenna system to inductively supply power to and communicate with the water seepage detection module is disposed proximate the water seepage detection module such that the antenna systems align. The intelligent roof drain system can detect water seepage under the roofing membrane and standing water proximate the roof drain and communicate such events to a gateway and/or building management system.

A water heating and treatment system includes a water heater, a hot water outflow line from the water heater, and a cold water supply line to supply water to the water heater. The cold water supply line includes at least one of an anti-scale device, and a UV sanitation lamp. A mixing station supplies a temperature regulated heated water to one or multiple temperature zones. The water heater, the anti-scale device, the UV sanitation lamp, and the mixing station are contained in a single enclosure having at least one transparent wall through which components can be viewed. A method for treating hot water to suppress pathogens and undesired bacterial content in a domestic water system is also described.

BACKFLOW PREVENTION ASSEMBLY HAVING A CARTRIDGE WITH DUAL ZONE TESTING
A backflow prevention assembly includes a body forming two buckets, wherein flow passes through the body from an inlet to an outlet along an axis and consecutively through each of the buckets. A single zone test cover encloses a first of the buckets to form a single zone chamber. A dual zone test cover encloses a second of the buckets with a dual zone cartridge assembly therein. The dual zone test cover has two test cocks. The dual zone cartridge assembly includes a frame having a valve seat, wherein the frame includes a lumen providing fluid communication from a dual zone chamber upstream of the valve seat to a first of the two test cocks of the dual zone test cover, and wherein the second of the two test cocks of the dual zone test cover is in fluid communication with the dual zone chamber downstream of the valve seat.
A backflow prevention assembly has a body having a first bucket with a sidewall extending between a closed end and an open end along a first bucket axis, a first conduit extending from an inlet of the sidewall of the first bucket, and a second bucket having a sidewall extending between a closed end and an open end along a second bucket axis. A second conduit extends between an outlet of the sidewall of the first bucket and an inlet of the sidewall of the second bucket, and a third conduit extends from an outlet of the sidewall of the second bucket. The conduits extend along a conduit axis that is perpendicular to the bucket axes. The valve assembly includes covers secured over the open ends of the buckets and a valve member located in each bucket that is biased to prevent reverse flow through the inlets of the buckets.
