Why Is Backflow Testing Important?

Backflow testing ensures your property’s water system is protected from contamination. Backflow happens when water reverses direction due to pressure changes, allowing potentially harmful substances to enter the water supply.

This can occur if:

  • A water main breaks

  • Firefighters open multiple hydrants

  • Irrigation systems, hose connections, or storage tanks experience pressure loss

To prevent this, backflow prevention devices are installed on water lines. During a professional test, our licensed technicians:

  • Uses backflow test gauge to test each component according to set standards in Illinois 
  • Inspect all valve components for correct operation 
  • Ensure the device is clear of debris. If it is not, the inspector will clean components thoroughly. 

Chicago requires these devices to be tested annually by a licensed backflow tester, and results must be submitted to the city to maintain compliance.

What Is A Cross-Connection?

A cross-connection is any actual or potential link between your drinking water system and a source of contamination. This could include:

  • Garden hoses submerged in buckets or pools

  • Irrigation systems

  • Chemical tanks

  • Fire sprinkler systems

Contaminants can flow backward into your clean water supply without a proper backflow prevention device, creating a serious health risk.

Chicago ordinances require businesses and facilities with cross-connections to test backflow devices annually, helping to protect you, your employees, and your customers.

For many Chicago businesses, backflow prevention devices and annual testing are mandatory by law. Residential properties may also require devices, especially if you have an irrigation system or private water features.

Even in residential settings, backflow can happen when:

  • Hoses are left submerged in pools or buckets

  • Irrigation systems connect directly to your water supply

  • Sudden changes in water pressure occur during emergencies

The best way to prevent this is through proper backflow prevention device installation and routine testing.

Backflow preventers are usually installed on your main water line, automatically sealing off the water flow if pressure changes are detected. This prevents contaminated water from entering your clean supply. Whether you own a home, manage a business, or oversee a large facility, proper installation and regular testing of backflow preventers are critical to keeping your water safe.
