Backflow Tester study plan

Define cross connection, backflow, backsiphonage, and backpressure in your own words without notes

Distinguish between pollution and contamination and classify five example scenarios under each

Map the hydraulic conditions that create backsiphonage versus backpressure using simple pressure diagrams you draw yourself

Identify the public health and system-integrity consequences of an unprotected cross connection in a written scenario

Explain the hierarchy of cross-connection control from source protection through containment to isolation

Describe the roles of the water purveyor, the property owner, and the certified tester in a containment program

Outline the elements of a written cross-connection control program including hazard surveys and recordkeeping

Trace how a typical municipal ordinance structures authority, inspections, and enforcement

Compare air gaps, reduced pressure principle assemblies, double check assemblies, pressure vacuum breakers, and atmospheric vacuum breakers on protection level and application

Match each device type to the hazard level it is approved for

Explain why an air gap provides the highest protection and what conditions degrade it

Select the correct device for six described installations and justify each choice in writing

Identify the components and operating principles of a reduced pressure principle assembly and a double check assembly

Describe how each device responds to backsiphonage and to backpressure

Explain the function of each check valve, the relief valve, and the sensing passage in an RP assembly

Recognize common installation errors such as improper orientation, missing drain clearance, and buried assemblies

Assemble the required test equipment and verify gauge calibration status before any test

List the correct sequence of steps for testing a reduced pressure principle assembly

List the correct sequence of steps for testing a double check assembly and a pressure vacuum breaker

State the acceptable pressure differential criteria for each test point from memory

Perform each test procedure on a training rig or simulator while narrating every step aloud

Diagnose five common failures such as a leaking check valve or a dribbling relief valve and state the likely cause

Apply the correct safety practices for handling test cocks, discharge, and high-pressure connections

Complete each procedure within a realistic time limit without skipping steps

Complete a full written test record for a simulated job including device details, gauge readings, and pass or fail determination

Explain reporting obligations, notification timelines, and record retention expectations

Resolve ten mixed scenario questions that combine hazard assessment with test interpretation

Review and correct your three weakest topics from weeks one through six

Take two full-length timed practice exams and record domain-level scores for each

Re-study every missed item until you can explain the correct reasoning without notes

Recite the device selection rules and all test acceptance criteria from memory

Finalize a one-page quick-reference sheet you can review in the days before the exam
