What Is a Backflow Preventer and Why Does It Matter?

A backflow preventer is a mechanical assembly installed in your plumbing system to stop contaminated water from flowing backward into the potable water supply. When water pressure drops suddenly, contaminated water from irrigation lines, fire suppression systems, or industrial processes can reverse direction and reach the clean water supply. Kapolei's mix of resort properties, retail centers, and industrial facilities along the Farrington Highway corridor all typically carry devices that require regular testing to remain compliant.

Hawaii BWS Compliance Requirements for Oahu Properties

Annual testing is required by the Honolulu Board of Water Supply. The BWS maintains a database of all permitted devices on Oahu and notifies property owners when testing is due. The first notice typically arrives 60 days before the due date, with progressive enforcement notices to follow if testing is not completed. Failure to comply can result in termination of water service. For commercial properties in the Kapolei Business Park and Kamokila Boulevard area, staying ahead of the BWS testing schedule is not optional.

What Happens If a Backflow Device Fails Its Test?

If a device fails, it must be repaired or replaced before a passing report can be submitted to BWS. Our team can handle the test and any necessary repairs in a single visit whenever possible, reducing downtime for your facility.

Our Certification and Testing Process

Our union journeymen and factory-trained technicians meet BWS and Hawaii State Department of Health requirements for certified backflow prevention assembly testing. Here is how our process works:

1. We review your BWS test notice and device records before the visit.
2. Our certified tester performs a full pressure differential and check-valve inspection on site.
3. We document results on BWS-required test forms immediately after testing.
4. If repairs or parts are needed, we address them on the same visit when possible.
5. We submit the completed test report to the BWS on your behalf.
