Backflow Prevention Device Testing

The State of New Jersey requires quarterly/bi-annual/annual backflow prevention device testing to protect the public water supply from harmful chemicals, toxins, bacteria and other non-potable entities.  It is important to hire a licensed and insured backflow prevention device company/inspector/tester to perform all the necessary tests to ensure compliance with NJ municipal/state mandates and regulations.

What’s the procedure for conducting a Backflow Prevention Device Test?

It is important to note that each backflow prevention device is tested differently, depending on the device at your facility.  Our licensed testers know how to test each different device to ensure the device is working correctly.  Before the test is started, our licensed tester will gather all of the device information such as make, model, serial number, size and device type.  Our tester begins the backflow prevention device test by shutting off the downstream shut off valve, this is one similarity that is shared between all of the devices.  The backflow prevention device must be tested in a no flow condition.  We then begin the test by connecting our test kit to the test ports on the backflow prevention device.  The test isolates each valve in the device to verify each valve is passing the requirements of a properly operating backflow prevention device.  When the test is completed, the water is then restored and a report is written up.

Do I have to get my Backflow Prevention Device tested every year?

Determining the frequency of testing a backflow preventer is dependent on the degree of hazard of the facility the device is in or what the device is connected to.  A high risk facility, where the water supply can cause severe illness or death, requires  quarterly testing.  A Reduced Pressure Zone device must be installed at high risk facilities.  Medium and low risk facilities, where the water supply could endanger health, requires testing annually and can use devices such as double check valves, pressure vacuum breakers or even reduced pressure zone devices.  To determine the degree of hazard at your facility, visit our At-Risk Facilities page.
