ASSE 5130 study plan

Define cross-connection, backflow, backsiphonage, and backpressure in your own words and diagram each condition

Map the regulatory chain from federal Safe Drinking Water Act authority down to state and local cross-connection programs, listing who enforces what

Classify the five backflow prevention method categories (air gap, RPZ, PVB, DCVA, AVB) by principle of operation and degree of hazard protected

Build a one-page hazard-rating reference that matches containment, isolation, and individual protection strategies to low, moderate, and high hazard scenarios

Sketch cross-section diagrams of RPZ, DCVA, PVB, AVB, and air gap assemblies labeling every component and its function

Explain the operating sequence of each assembly during normal flow, backsiphonage, and backpressure conditions

Match each assembly type to its allowable installation orientation, pit/underground restrictions, and hazard level

Identify the field-test connection points and test cock numbering on each assembly type from memory

Assemble and zero a differential pressure test kit, verifying gauge calibration, hose condition, and needle movement

Execute the RPZ field test sequence (leakage, check valve 1, check valve 2, relief valve opening point) in correct order while narrating each step

Execute DCVA and PVB test sequences and record readings on a standard test form

Calculate allowable pressure drop values and recognize readings that indicate a failing check valve

Diagnose common failure signatures: relief valve dribbling, check valve not holding, and gauge drift, and state the corrective action for each

Disassemble, inspect, and reassemble an RPZ and a DCVA using the correct seat, disc, and O-ring replacement procedure

Perform a timed full test on each assembly type within a realistic field time window

Explain the difference between a field test failure and an installation defect that mimics a test failure

Write the preventive maintenance schedule for each assembly type including inspection frequency and wear-part replacement intervals

Apply installation requirements for elevation, drainage, freeze protection, and accessibility to five different site scenarios

Determine correct assembly sizing and pressure loss considerations for a given flow demand

Identify the required clearances and orientation limits that cause most installation rejections

Conduct a mock site survey of a real or imagined facility, locating every cross-connection and assigning a hazard rating

Select the appropriate assembly or method for each identified cross-connection and justify the choice in writing

Draft a complete test report and notification record that meets typical regulatory content requirements

List the personal protective equipment, confined-space, and water-quality safety practices required during testing and repair

Re-test every assembly type under time pressure and document any procedural errors for correction

Review recordkeeping retention rules, reporting timelines, and the consequences of noncompliance

Revisit regulation and liability questions you missed on earlier self-quizzes and close each gap

Practice explaining a failed test result to a property owner in plain language

Take two full-length timed practice exams and score each by domain to find remaining weak areas

Drill only the lowest-scoring domain until practice accuracy reaches 85% or better

Recite the critical specifications, tolerances, and regulatory deadlines from memory without notes

Review your error log from all prior weeks and confirm every entry is closed
