Viega is a family business dating to 1899 with sales estimated at more than $600 million. Now headed by the fourth generation of the Viegener family, the company makes more than 10,000 plumbing-related products, only a handful of which are currently marketed in the United States.
These consist mainly of Viega's Pro-Press fittings, made in two plants in Germany. The Pro-Press XL (extra large) line, along with various products limited to the European market, come out of the firm's world headquarters in the little town of Attendorn about 90 miles north of Frankfurt. Smaller copper fittings get made a couple of hundred miles away in Grossheringen, a hamlet in the eastern part of the country.
