A water sediment filter assembly includes a screen member and a drain port which permits the removal of collected debris. The water sediment filter assembly includes a valve member which can be moved to different positions to permit the draining of collected sediment through the drain port.

An isolation assembly for a boiler unit that incorporates a pressure relief valve and an automatic air vent to a valve body that includes a valve positioned adjacent to the automatic air vent. The unitary valve body reduces the number of components and leak paths and incorporates a ball valve to permit removing and/or securing the automatic air vent without having to purge the adjacent plumbing system.

A serviceable swing check valve assembly includes an access port for servicing the swing check valve. The valve assembly also includes a strainer that strains the fluid before it reaches the swing check valve. A valve assembly is positioned adjacent to a drain port to drain the debris that is collected by the strainer.

An isolation mounting arm for use with an expansion tank has a passageway with a first end portion, a second end portion, and a medial portion located between the first end portion and the second end portion with the drain port located at the terminal end of the second end portion. A first tee is located in the first end portion with oppositely disposed first and second ports. A second tee is located in the second end portion, with oppositely disposed fourth and fifth ports. A first valve member is coupled to the first port, a second valve member is coupled to the second port, and a third valve member is located adjacent to the drain port. An expansion tank is coupled to either the fourth port or the fifth port with a plug coupled to the other port.

A plumbing system pressure protection valve assembly that utilizes a unitary body to connect a hot water tank to a cold water supply, a vacuum breaker, and an expansion tank. The assembly includes two ball valves coupled to the unitary body to isolate the hot water tank from the cold water feed and to isolate and permit draining of the expansion tank. The assembly also includes a rod and foot coupled to a tab on the unitary body to provide support for the expansion tank service valve assembly.

A motorized zone valve assembly permits the servicing and/or replacement of a motorized zone valve in a hydronic heating and/or cooling system. The motorized zone valve assembly includes isolation valves coupled to the incoming and outgoing ports of the motorized zone valve via union nuts. The isolation valve members can be closed to permit the removal of the motorized zone valve by the loosening of the two union nuts. In addition, the isolation valve coupled to the outgoing port can include a drain valve and drain port to permit the isolation and draining of individual zones of the hydronic system.

A water supply monitoring system in connection with a supply line includes sensors configured to detect supply properties, including a temperature, flow rate, and/or a pressure in the supply line. A controller receives the supply properties from the sensors and compares the supply properties to detection metrics. In response to a comparison of the supply properties relative to the detection metrics, the controller identifies an anomaly of a fluid supply or a consumption device. In response to the anomaly, the controller identifies a corrective action that may include a repair or installation of a conditioning device for the fluid supply and/or one of the consumption devices.

A dual union drain valve assembly has one or more reversible check valve inserts in the fitting(s) that are coupled to the drain valve body. The coupling of the fittings to the drain valve body is done using union couplings permitting the easy installation and/or reversal of the check valve insert(s). In addition, the union couplings permit removal of the dual union drain valve assembly from the surrounding plumbing system for service or replacement of the dual union drain valve assembly.
