A washer box valve(s) with water hammer arrestors utilizes union connection fittings and check valve inserts to provide additional backflow protection to the system. The check valve inserts are positioned in coupling members that prevent backflow into the incoming hot and cold water supply lines. The water hammer arrestors are coupled to a valve body that has an inlet, an outlet, and an optional drain port.

A piping component that includes (i) a piping body with an open end; and (ii) an alloy comprising (by weight percentage) 12% to 16.5% zinc, 0.265% to 1.6% silicon and sufficient copper so that the sum of the weight percentages of the zinc, silicon, and copper in the alloy is at least 99.7%. The alloy exhibits an elongation that is within a range of 60% to 70%. Additionally discloses is a piping component including (i) a piping body with an open end; and (ii) a cold worked alloy comprising (by weight percentage) 12% to 16.5% zinc, 0.265% to 1.8% silicon and sufficient copper so that the sum of the weight percentages of the zinc, silicon, and copper in the alloy is at least 99.7%. In embodiments, the weight percentage of the silicon in the alloys disclosed can be 0.5% to 1.6%, 0.5% to 1.8%, or 0.5% to 2.0%.

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.

A water heater drain valve assembly with T-flow adjustability. The water heater drain valve assembly includes a first valve at the tee in the valve body. The first valve is a 3-way ball valve. A second valve is located on the branch outlet of the valve body. One fitting end of the heater drain valve is longer in comparison to the other end and the drain port. This longer fitting end permits the water heater drain valve assembly to be directly coupled to a water heater.

An isolation bypass valve assembly includes a bypass valve located between two tees in the valve body. One or more of the ports extending from the tees can include an isolation valve.

A water heater drain valve assembly with T-flow adjustability. The water heater drain valve assembly includes a first valve at the tee in the valve body. The first valve is a 3-way ball valve. A second valve is located on the branch outlet of the valve body. One fitting end of the heater drain valve is elongated in comparison to the other end and the drain port. The elongated fitting end permits the water heater drain valve assembly to be directly coupled to a water heater.

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 magnetic water filter assembly with a removable lighter weight lower section to permit access to the internal components of the filter assembly. The removable lower section allows the servicing and/or replacement of the internal filter as well as cleaning of the assembly. The lighter weight lower section reduces the stress placed on the surrounding plumbing components, including the piping/tubing that couples to the filter assembly.
