Cambridge Brass is a "Water Service Valves and Fittings Manufacturer", providing leaded and non-leaded machined and assembled sand castings into the North American Waterworks Industry for over 100 years. It became known as Cambridge Brass in 1979 through the merger of the waterworks manufacturer, Canadian Brass with Waltec Industries, a large Ontario plumbing manufacturer. During the 1980s lead became recognized as a health hazard, leaded solder was removed from use in 1988 followed by other plumbing products including faucets by the late 90s. As the brass casting sub-contractor for Delta Faucet Canada, Cambridge Brass through this period of adjustment learned the technology required to cast no-lead plumbing faucet parts to replace leaded brass components. Following this successful accomplishment, and at the request of the Waterworks Industry they began casting no-lead waterworks valves and fittings and sending these lead free products into the Industry. Gerry Gunn has many years of direct experience at Cambridge Brass. Starting in the Plant as a Professional Engineer in the late 70s, he then took responsibilities as Chief Engineer (including product development) and then Marketing and Sales before taking over as General Manager in 1995. With his guidance and leadership the Cambridge Brass team of Sales and Marketing, Manufacturing and Logistics personnel developed the designs, tooling and logistics necessary to produce no-lead waterworks brass, and this was accomplished already by the year 2000. To test their no-lead products and applications Cambridge enlisted the help of Environmental Quality Institute, a North American expert in lead testing located in Asheville, North Carolina. Gerry set up the EQI efforts, under the direction of Professor Rick Maas. Rick brought many talented scientists and agencies from across the United States to his assistance, culminating in a very powerful video being prepared. This video is included in this XCG course. Thank you EQI, and Cambridge Brass.
