How to file your backflow test report

Gwa Central Water System accepts backflow test reports by email. BackflowGo has the report inbox on file — enter your test readings once and BackflowGo submits for you in one tap: the platform fills the correct official form, attaches the PDF, and emails it straight to the purveyor's cross-connection program, with a copy for your records.

Filing on your own? Ask the utility for its backflow report submission address, then send the completed test form within your jurisdiction's deadline.

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.
