Domestic Backflow Inspections Explained

Domestic Backflow

Domestic backflow preventer assemblies are installed to safeguard the drinkable water supply in apartment buildings, high rises, other multifamily buildings, and commercial buildings from any dirt, debris, or chemicals. Our inspections adhere to the guidelines outlined by local plumbing codes and ASSE, ABPA, and the American Water Works Association (AWWA) Manual M14. Here’s how we approach domestic backflow preventer inspections:


1. Notification of Water Suspension:

We will notify the authority/management onsite of a brief, temporary water interruption and verify that the time works for the onsite tenants/residents.


2. Visual Domestic Backflow Inspection: 

Our technicians thoroughly examine the domestic backflow preventer assembly, including check valves, relief valves, shutoff valves, test cocks, and pressure gauges. They check for any signs of damage, deterioration, or improper installation.


3. Functional Testing: 

The assembly is tested to ensure proper operation and prevent backflow of the domestic water supply. This includes conducting a differential pressure test to assess the integrity of the check valves and evaluating pressure settings. Test cocks are also inspected for proper functionality.


4. Compliance Verification: 

We ensure the domestic backflow preventer assembly complies with local plumbing codes and regulations. Our technicians confirm that the assembly is correctly installed, adequately protected, and properly labeled.


5. Documentation: 

We provide detailed documentation of the inspection findings, including any deficiencies or recommended repairs. This documentation is essential to comply with regulatory requirements and maintain a comprehensive inspection history.
