Industry History
The Back Flow Prevention Devices (Wholesale) industry has a long history dating back to ancient times when the Greeks and Romans used simple check valves to prevent the backflow of water in their aqueducts. In the 19th century, the first double check valve was invented, which was later improved upon by the introduction of the reduced pressure principle valve in the 20th century. In the United States, the industry saw significant growth in the 1970s and 1980s due to the introduction of new regulations requiring the installation of backflow prevention devices in commercial and industrial buildings. In recent years, the industry has continued to grow due to increased awareness of the importance of water safety and the need for regular maintenance and replacement of aging devices.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification. It is not an official U.S. Census Bureau NAICS code. Its parent industry is an official NAICS classification defined by the U.S. Census Bureau. Classifications are reviewed regularly by SICCODE.com's Classification Review Team.
SICCODE.com classifies companies under both Extended NAICS and Extended SIC. A company may appear in both classification systems, so company counts should not be added together without deduplication.
