For any commercial property, the integrity of its water supply is paramount. Not only is it crucial for daily operations, but it’s also a matter of public health and safety. That’s where commercial backflow testing comes into play. This vital service ensures that contaminated water from your property doesn’t accidentally flow back into the public drinking water system.
What is Backflow and Why is it a Concern?
What is Backflow and Why is it a Concern?
- Backpressure: When the pressure within your facility’s plumbing system exceeds the pressure in the municipal water supply, forcing water backward.
- Backsiphonage: A drop in pressure in the main water supply (e.g., due to a water main break or high water demand from firefighting) can create a vacuum, pulling contaminated water from your property back into the public system.
Imagine chemicals from an industrial process, stagnant water from a fire sprinkler system, or even water from a boiler being drawn back into the community’s drinking water! This poses a severe health risk, potentially spreading harmful bacteria, chemicals, and other pollutants.
The Mandate for Commercial Backflow Testing
Due to these significant risks, most municipalities, including the City of Wyoming, MI, and state regulations (like the Michigan Safe Drinking Water Act), mandate regular backflow prevention testing for commercial properties. These regulations require the installation of approved backflow prevention devices at cross-connection points – where potable (drinkable) and non-potable water lines meet.
These devices act as a one-way gate, allowing water to flow only in the intended direction. However, like any mechanical device, they can fail over time. That’s why annual testing is crucial to ensure they are functioning correctly and providing the necessary protection.

Why You Need a Certified Backflow Tester
When it comes to something as critical as public health, expertise matters. It’s imperative that your commercial backflow testing is performed by a qualified and certified backflow inspector. In Michigan, for a public water supply official to accept backflow prevention testing results, the tester must have a valid ASSE 5110 certification.
A certified inspector possesses the specialized knowledge and hands-on skills to:
- Accurately identify potential cross-connection hazards.
- Properly test all types of backflow prevention assemblies (e.g., Reduced Pressure Zone Assemblies, Double Check Valve Assemblies).
- Diagnose any malfunctions or issues with the device.
- Submit accurate reports to the local water authority, ensuring your compliance.
Choosing an uncertified tester not only risks your business’s compliance with local regulations and potential fines but, more importantly, jeopardizes the safety of your water supply and the community.
New Construction vs. Commercial Plumbing Maintenance
New Construction: For all new commercial construction projects, backflow prevention devices are a mandatory installation at the connection to the public water supply. These devices must be tested upon installation to ensure they are properly configured and functioning before water service can be fully activated. This initial test is a critical step in securing the building’s certificate of occupancy and demonstrating adherence to plumbing codes.
Commercial Plumbing Maintenance: For existing commercial properties, backflow prevention testing is a cornerstone of ongoing plumbing maintenance. Regular annual testing is required by law for most commercial properties in Michigan, and notifications are sent when devices are due. This proactive approach ensures continuous protection against contamination and helps identify and address any issues before they lead to costly water damage, health risks, or service interruptions.
