Do You Need Your Backflow Preventer Certified?

Backflow testing is a cornerstone of water safety services, designed to detect any failures in the system that could compromise water quality. This critical service is the first defense against contamination, protecting the community from potential health hazards.

Why Should I Get My Backflow Preventer Checked?

  • Health and Safety: Our testing process is rigorous, focusing on preventing any contamination that could affect the public's health.
  • Regulatory Compliance: We keep abreast of the latest regulatory changes to ensure your system is always compliant.
  • System Integrity: By identifying issues early, we help avoid costly repairs and maintain consistent system performance.

Need Backflow Preventer Replacement or Repair?

If your backflow preventer is leaking, failing a required test, or no longer operating as designed, timely repair or replacement is essential. These devices protect your potable water supply, and when they malfunction, they can put both safety and compliance at risk.

Backflow Preventer Repair

In many cases, worn internal components, seals, or valves can be repaired to restore proper function. Our team evaluates the condition of your existing device and recommends repairs when they’re a safe and code-compliant option.

Backflow Preventer Replacement

If a device is outdated, severely damaged, or fails testing beyond repair, replacement may be the best solution. We install approved backflow preventers for residential and commercial systems, selected based on your specific application and regulatory requirements.

Testing & Compliance Support

After repairs or replacement, we test and certify the device to confirm it meets local and industry standards, helping you avoid failed inspections, violations, and service interruptions.

When to Call a Professional

You should contact a certified backflow professional if you notice any of the following:

  • Your water looks, smells, or tastes unusual
    Changes in color, odor, or clarity can point to contamination risks that need immediate attention.

  • Your backflow preventer is leaking or constantly discharging water
    Active leaks or relief valve discharge usually mean internal components have failed and the device can’t protect the water supply properly.

  • You’re experiencing sudden or inconsistent water pressure
    Pressure fluctuations may indicate the device is stuck, damaged, or no longer regulating flow as designed.

  • Your backflow device failed a required test or inspection
    A failed test isn’t just a paperwork issue — it often means repairs or replacement are needed to stay compliant.

  • You’re unsure when the device was last tested or maintained
    If maintenance history is unclear, professional testing can confirm whether the device is still protecting your system.

Calling a professional early can prevent contamination, failed inspections, and costly emergency repairs — especially for commercial properties with strict compliance requirements.

Backflow Prevention FAQs

Do I really need a backflow preventer?

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.

How often should backflow prevention be tested and inspected?

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. To learn more about having your backflow preventer tested, give us a call today. 

Who submits backflow certification paperwork to the city?
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. 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.
What are the different methods used for backflow prevention in plumbing systems?

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.

How do I know if my property is at risk of backflow contamination?

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.

What are the common issues with backflow preventers and how can they be resolved?

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.

What should I do if my backflow prevention device fails a test?

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.
