How to file your backflow test report

Confirm the submission channel with the utility before filing. Andersen Air Force Base Water System has not yet been verified for a specific submission route — some purveyors accept reports by email, others use a portal vendor or take paper filings. BackflowGo tracks this data across 49,000+ US water systems and keeps it current as purveyors confirm their channels.

The Guam form requirement

USC-GU

Guam does not mandate a single statewide test form. Most purveyors accept the standard USC/AWWA-style report, which BackflowGo generates — requirements live at the purveyor level.

Guam Waterworks Authority requires annual testing (28 GAR §2114) by a tester on GWA's approved list, with records furnished to GWA on a GWA-prescribed form that is not published — confirm the form with GWA Compliance & Safety ((671) 300-6885) before first filing; GWA rejects reports from non-approved testers.
