What Is Backflow Testing?

Backflow testing is the process of ensuring that your plumbing system effectively prevents the reverse flow of contaminated water into the clean drinking water supply. "Backflow" occurs when pressure changes cause harmful water to flow back into your potable water, posing serious health risks.


This essential test confirms that your building's plumbing complies with local and state regulations while safeguarding the community's water supply. The process involves temporarily shutting off the water, inspecting the backflow preventer valve, and conducting tests to ensure it's working properly.


Annual backflow testing is often required for commercial and industrial properties to prevent water contamination and protect public health. By ensuring your plumbing system meets these standards, you help maintain a safe, healthy water supply for everyone.

What Are the Benefits of Backflow Testing?

The benefits of backflow testing are crucial for both residential and commercial properties. Regular backflow testing helps protect your drinking water from contamination by ensuring that your plumbing system’s backflow prevention device is working properly. Here are the key advantages:

  1. Protects Your Water Supply: Backflow testing prevents pollutants, chemicals, and other harmful substances from reversing into your clean water, safeguarding your health and the community.
  2. Ensures Compliance with Regulations: Many local and state regulations require annual backflow testing, especially for commercial and industrial buildings. Staying compliant avoids potential fines and legal issues.
  3. Prevents Health Hazards: By catching backflow issues early, backflow testing helps reduce the risk of waterborne diseases and other health hazards caused by contaminated water.
  4. Improves System Efficiency: Regular testing can identify plumbing issues, ensuring that your system runs smoothly and preventing costly repairs down the line.
  5. Peace of Mind: Knowing your water supply is safe and meets legal standards provides peace of mind for both homeowners and business owners.
