Backflow Prevention: Protecting Your Water Supply

Backflow prevention might sound like a technical term, but it's crucial for the safety and health of your community's water supply. In simple terms, backflow occurs when the normal flow of water in a plumbing system reverses, potentially contaminating the drinking water source.

How Does Backflow Happen?

• High Pressure: When there's a sudden increase in pressure within your plumbing system, it can force water to flow backwards.

• Cross-Connection: A physical connection between the potable (drinkable) water supply and a non-potable water source (like an irrigation system or swimming pool) can create a pathway for contamination.

The Dangers of Backflow:

• Contamination: Backflow can introduce harmful substances into the drinking water supply, such as:

• Sewage

• Chemicals (from pools, fertilizers, or industrial processes)

• Bacteria

• Health Risks: Contaminated drinking water can pose serious health risks, including:

• Gastrointestinal illnesses

• Skin infections

• More severe health problems in vulnerable populations

Backflow Prevention Devices: Your Line of Defense

To prevent backflow, specific devices are installed on plumbing systems:

• Pressure Reducing Valves (PRVs): These valves maintain a consistent water pressure, preventing excessive pressure that could cause backflow.

• Reduced Pressure Zone (RPZ) Devices: These are more complex devices that create two checks to prevent backflow. They are typically required for higher-risk situations.

• Double Check Valve Assemblies: These devices use two check valves to prevent backflow.

Who Needs Backflow Prevention?

• Businesses: Many businesses require backflow prevention devices, including:

• Restaurants

• Hospitals

• Industrial facilities

• Irrigation systems

• Homeowners: While less common for residential properties, certain situations may require backflow prevention, such as:

• Homes with irrigation systems connected to the municipal water supply

• Homes with swimming pools or hot tubs with potential cross-connection risks

Regular Inspections and Maintenance:

• Regular inspections and testing of backflow prevention devices are crucial to ensure they are functioning correctly.

• Certified professionals should conduct these inspections and repairs.

Protecting Your Community:

Backflow prevention devices play a vital role in protecting the safety and quality of our drinking water. By ensuring these devices are properly installed and maintained, we can safeguard public health and prevent potential contamination.
