Quick Answers

Good To Know

What is the purpose of backflow prevention?

The purpose of backflow prevention is to protect the public water supply from contamination by preventing non-potable water from flowing back into the potable water supply. This helps to ensure that the water we drink and use is clean and free from harmful contaminants.

What is the best way to prevent backflow?

The best way to prevent backflow is to install backflow prevention assemblies, which are designed to prevent water from flowing in the wrong direction. These assemblies can be installed at various points in the plumbing system, depending on the property and the level of backflow risk.

What is the only safe method for backflow prevention?

The only safe method for backflow prevention is to use backflow prevention assemblies that are approved by the county or state regulatory agency. These assemblies are designed to meet specific standards and regulations to ensure their effectiveness and safety.

What is the most common backflow prevention device?

The most common backflow prevention device is the Reduced Pressure Zone (RPZ) assembly. This device uses a series of valves to prevent backflow by creating a barrier between the potable water supply and any potential sources of contamination. Other types of backflow prevention devices include double check valves, pressure vacuum breakers, and atmospheric vacuum breakers.
