About Backflow Preventers
Backflow preventers are essential plumbing devices used to protect potable water systems from contamination and pollution caused by backflow of non-potable water or other substances. The backflow preventer ensures that the water flows in only one direction, preventing any backflow of water from the plumbing system back into the water supply.
Types of Backflow Preventers
There are various types of backflow preventers available in the market, including reduced pressure zone (RPZ), double check valve (DC), and pressure vacuum breaker (PVB). Each type of backflow preventer has its unique features, making them suitable for different applications. The selection of the type of backflow preventer depends on various factors such as pipe size, connection type, body material, series, maximum pressure, and temperature range.
How Backflow Preventers are Made
Backflow preventers are made of various materials such as brass, stainless steel, and plastic. The body of the backflow preventer is designed to provide a reliable, long-lasting, and leak-proof seal. The internal components, such as the check valves and relief valves, are made of rubber, neoprene, or similar materials to ensure they function correctly. Backflow preventers are manufactured using advanced technologies and tested to ensure they meet the required performance standards.
