BackflowPass field library
Backflow testing guides built around the questions the field actually raises.
Clear, source-led explanations for certified testers, facility teams, contractors, and program staff. Every guide names its jurisdictional boundary and links to the primary source behind the claim—because an accepted form or procedure is local, not generic.
Start with the question you actually have
Understand the protection
Start with assemblies, devices, cross-connections, and the pressure conditions that make backflow a risk.
Find the right reporting question
Separate the field result from the form, recipient, deadline, and local acceptance rule.
Confirm local authority
Use a current water-system or authority source before choosing, testing, repairing, or submitting an assembly record.
Source-led guides
These pages own distinct information jobs. They do not prescribe an assembly for a property, create a universal form, or replace an accepted field procedure.

Backflow prevention assemblies: what they are, and why testability matters
A plain-English guide to backflow prevention assemblies: the difference between an assembly and a device, how backpressure and backsiphonage happen, and what an approved field record establishes.

RPZ vs. DCVA vs. PVB: what the assembly types protect against
Compare common backflow prevention assembly families—RP/RPZ, DC/DCVA, PVB, and SVB—with a clear explanation of backpressure, backsiphonage, testing, and local approval limits.

Backflow test reports: the fields, records, and local submission rules that matter
A source-led guide to backflow test reports: common record fields, why a generic form may be rejected, how failed tests and retests should be documented, and where to confirm local submission rules.

What to do after a failed backflow test
A careful, jurisdiction-aware guide for a failed backflow test: preserve the initial result, confirm the receiving authority's instructions, document repair or replacement, complete a retest, and retain the record trail.

Backflow testing checklist: prepare the visit, document the result, confirm the filing
A field-readiness checklist for certified backflow assembly testers: verify local procedure, program acceptance, assembly identity, access, gauge records, test documentation, and the final filing path.

Cross-connection control programs: the records and workflows behind backflow prevention
A source-led overview of cross-connection control program elements: authority, hazard surveys, approved protection, tester qualification, testing and repair records, communication, and incident response.

Backflow testing software: evaluate the field-reporting workflow before you switch
An evaluation checklist for backflow testing software: assembly-family fields, local form acceptance, tester and gauge details, failure and retest history, offline work, export, and records ownership.

ASSE 5110 certification: what it qualifies, what the assessment covers, and what to verify locally
A source-led ASSE 5110 certification roadmap: the standard's scope, ASSE program prerequisites and assessment structure, renewal, and why state or water-system recognition still needs local verification.
