San Diego Backflow Installation, Service, and Inspection

Courtesy Plumbing, Inc. has the certified and experienced staff to install, inspect, and service your commercial or residential backflow. Ordinarily, water flows in one direction to the consumer. Due to various hydraulic conditions, cross connection and backflow conditions can contaminate the public drinking water. Ensure the safety of the community and legal compliance with health safety laws with a Courtesy Plumbing, Inc. backflow inspection.

Who needs a backflow?

Anyone with auxiliary system or supply needs a backflow prevention device. Any commercial or professional building with a sprinkler system, lab equipment, boiler, water storage tank, etc. needs a backflow prevention device. Courtesy Plumbing, Inc. recommends residential clients to protect their community drinking water supply with a backflow prevention device.

A backflow prevention device is used to protect water supplies from contamination or pollution. Many types of backflow prevention devices also have test cocks so that they can be tested or examined to ensure that they are functioning properly. In the USA, the Environmental Protection Agency (EPA) holds local water suppliers responsible for maintaining a certain amount of purity in potable water systems. Many states and/or local municipalities require annual testing of backflow prevention assemblies. A check valve is a common form of backflow prevention.

Backflow prevention protects the potable water system from minor, moderate, and severe hazards. There are over 10,000 reported cases of backflow contamination each year. Some cases can be fatal. Backflow devices are required by law where needed and must be installed in accordance with plumbing or building codes. A backflow assembly has test cocks and shut-off valves and must be tested each year, if relocated or repaired, and when installed.
