Backflow Device Testing in Kapolei, HI

Yes, the Oahu Board of Water Supply requires annual testing for all permitted backflow prevention assemblies on the island. Properties in Kapolei and across Oahu must have a certified tester perform and document the test each year.

Only a certified backflow prevention assembly tester recognized by the Board of Water Supply can perform the test. Action Plumbing serves properties throughout Honolulu and across Oahu.

Non-compliance with the Board of Water Supply's testing requirements can result in water service termination. Scheduling your test keeps your Ewa Beach, Kailua, or Kaneohe property in good standing with the BWS.

The test verifies that your assembly's internal valves, seals, and relief components are working correctly and that no unauthorized changes have been made to the device. A completed verification form is then submitted to the Board of Water Supply.

Properties with irrigation systems connected to the public water supply on Oahu are subject to cross-connection control requirements. Contact Action Plumbing to confirm what applies to your specific property in areas like Pearl City, Aiea, or Mililani.

Yes, properties with more than one backflow prevention assembly require individual testing and documentation for each unit. Action Plumbing serves residential and commercial properties across all the zip codes we cover on Oahu.
