Backflow Prevention

For commercial property owners, backflow preventers are required by federal law. You must also have these devices regularly tested to certify that they are compliant with the code.

Residential customers are not required to have a backflow preventer; however some situations will warrant the installation of one. For instance, if your home has an underground lawn irrigation system, most likely it is required that you have a backflow preventer.

Commercial backflow prevention should be tested and inspected once every year and residential backflow prevention should be tested every one to three years depending on your town or city. Having your backflow preventer tested is a good way to ensure that it is functioning properly. Issues with your backflow preventer can pose a safety risk to your health and your home.

Whenever you have an installation, alteration or replacement of existing plumbing systems, permits and documentation will usually be required to ensure that it is up to safety and health standards. For homeowners, this process of documentation and obtaining permits for plumbing installations and modifications can be complex. Water Worx Services will take care of this process for every customer when we perform a service that requires paperwork to be submitted to the city.

Several methods are employed for backflow prevention in plumbing systems. These include:

Air gaps: Creating a physical separation between the water outlet and potential contaminants.

Check valves: Installing valves that allow water to flow in one direction only, preventing backflow.

Reduced pressure zone (RPZ) devices: These assemblies use a series of check valves and relief valves to maintain lower pressure, preventing backflow.

Double-check valves: Utilizing two check valves to prevent backflow in low-risk applications like irrigation systems.

Atmospheric vacuum breakers: Devices that prevent backflow by breaking the vacuum in the system.

Several factors can indicate if your property is at risk of backflow contamination. Properties with irrigation systems, fire sprinkler systems, or boilers are at higher risk. Additionally, if your property is located downhill from potential sources of contamination, such as chemical storage facilities or industrial sites, the risk increases. Similarly, properties with outdated or poorly maintained plumbing systems are more susceptible. Consulting with a qualified plumber or backflow prevention specialist can help assess your property's risk and recommend appropriate preventive measures.

Common issues with backflow preventers include valve leaks, debris blocking the valve, and pressure fluctuations causing malfunctions. To resolve these issues, regularly inspect and clean the valves, ensure proper installation, and maintain consistent water pressure. If a valve leak persists, replacing worn-out parts or the entire valve may be necessary. Annual professional testing and maintenance can help detect and address problems early, ensuring the system functions correctly and complies with local regulations.

If your backflow prevention device fails a test, it’s crucial to take immediate action. Contact a certified plumber or backflow specialist to inspect and diagnose the issue. The device may need repair or replacement to restore its functionality and ensure the safety of your water supply. Until repairs are made, avoid using the affected water sources to prevent potential contamination. After the repair, schedule a follow-up test to confirm the device is functioning properly and in compliance with local regulations.
