What Happens During Backflow Testing?
In some commercial plumbing systems, there is already an air gap present. It’s used to prevent backflow from happening. This air gap is an open vertical space within the plumbing system that prevents cross-contamination. But in places where there’s even a small risk of backflow entering the public supply pipes, a backflow preventer needs to be present.
And in order to ensure that any backflow preventer put in place actually works as it should, it needs to be routinely tested. One of our expertly trained service professionals will connect a test kit to the backflow prevention device in order to verify that it is functioning properly. This service requires that all water downstream of the backflow device be shut off to perform the test. Please don’t hesitate to contact our team if you have any questions about this process!
