Backflow Testing Requirements for Commercial Properties
Backflow Testing Requirements for Commercial Properties
Introduction
Backflow prevention is a critical component of commercial plumbing systems, ensuring that contaminants do not enter the clean water supply. Due to the potential hazards associated with cross-connections, most municipalities require annual backflow testing for commercial properties. Failure to comply can result in fines, service disruptions, and increased health risks.
In this article, we’ll outline commercial backflow testing requirements, key compliance factors, and best practices for maintaining a safe water supply.
Why Commercial Properties Must Test Backflow Preventers
Backflow can occur when changes in pressure cause water to reverse direction, potentially pulling chemicals, bacteria, or other contaminants into the drinking water supply. Commercial properties pose a higher risk due to larger plumbing systems, irrigation, and fire suppression systems.
To prevent contamination, most local governments require businesses to install and test backflow preventers annually. These requirements apply to:
✔️ Office buildings – Commercial water lines must be protected against cross-connections.
✔️ Restaurants & food service – Beverage dispensers, dishwashers, and sinks require backflow protection.
✔️ Industrial facilities – Manufacturing processes often involve chemicals that could enter the water supply.
✔️ Fire suppression systems – Water in fire sprinklers can stagnate and become hazardous if it flows backward.
✔️ Medical & dental offices – Sterilization equipment and medical waste pose contamination risks.
Backflow Testing Regulations for Commercial Properties
Most municipalities follow similar backflow testing requirements for commercial buildings. Here are examples from major Colorado cities:
✔️ Longmont, CO: Requires annual testing by a certified tester, with results reported to the city. Testing must be completed between April and September. (Longmont Backflow Regulations)
✔️ Fort Collins, CO: Mandates annual testing for all commercial, industrial, irrigation, and fire line services. (Fort Collins Backflow Requirements)
✔️ Denver, CO: Requires all commercial properties to have a backflow prevention device installed and tested once per year by a certified tester. Failure to comply may result in water service interruptions. (Denver Water Backflow Policy)
Non-compliance with these regulations can lead to fines, penalties, and potential water shut-offs for businesses.
What Happens During a Backflow Test?
A certified backflow tester will:
✔️ Inspect the device for leaks, corrosion, or visible damage.
✔️ Use specialized equipment to measure pressure levels and valve function.
✔️ Ensure the backflow preventer is working as designed to prevent contamination.
✔️ Submit test results to the required municipal authority.

Consequences of Not Testing Your Backflow Preventer
✔️ Fines and legal penalties – Local governments can issue citations for untested backflow devices.
✔️ Water service interruptions – Cities have the authority to shut off water service to non-compliant properties.
✔️ Health risks – A faulty backflow preventer can allow contaminants to enter your business’s water supply.
✔️ Higher repair costs – Minor issues caught early can prevent expensive replacements later.
Best Practices for Commercial Backflow Compliance
✔️ Schedule testing early – Avoid last-minute compliance issues by booking annual tests in advance.
✔️ Work with certified testers – Ensure compliance by hiring professionals with proper certifications.
✔️ Keep records of all tests – Maintain reports for regulatory inspections and proof of compliance.
✔️ Inspect systems regularly – Look for leaks or pressure fluctuations between tests.
✔️ Stay informed about regulation changes – Backflow requirements can vary by city and state.
