ASSE 5140 study plan

Map every backflow prevention term (air gap, RPZ, PVB, DCVA, AVB) to its definition and permitted application from memory on a blank sheet

Trace the cross-connection control logic of a reduced-pressure principle assembly step by step, labeling each check and relief component and its failure mode

Build a one-page comparison table contrasting the five backflow assembly types by degree of hazard, orientation, and where each may be installed

Identify the code-fundamentals provisions that govern cross-connection control and cite the section intent in your own words

Explain the difference between backsiphonage and backpressure and construct one realistic field scenario for each

Outline the annual testing procedure for a testable backflow assembly, listing the sequence of gauge connections and the pass/fail criteria for each check

Describe the components of a potable water distribution system from service line through meter, main, riser, and fixture branch

Calculate required pipe sizing inputs for a simple residential layout using fixture-unit values and developed length

Differentiate pressure-driven supply design constraints: static versus residual pressure, friction loss, and minimum fixture pressure requirements

Interpret how water heater, expansion control, and thermal expansion protection interact with the supply side of a system

Compare the code treatment of potable water pipe materials, joints, and supports against the mechanical code's parallel requirements

Solve three practice problems converting fixture units to demand and selecting a meter size

Diagram a full drainage stack with fixture branches, a vent stack, and a stack vent, labeling every fitting and its function

Distinguish between trap arm, fixture drain, soil stack, waste stack, and building drain and state the slope requirement for each horizontal run

Explain the purpose and placement rules for each vent type: individual, common, wet, circuit, and island fixture venting

Relate the drainage and vent provisions to the broader mechanical code's trap seal protection intent

Apply trap seal protection principles to explain why venting failures cause gurgling, sewer gas, and slow drains

Compare the installation requirements for water closets, lavatories, sinks, and floor drains, including fixture spacing and clearance

Describe water heater types, relief valve placement, discharge piping, and combustion air requirements for fuel-fired units

Diagnose five written drainage/vent or fixture scenarios and state the code violation and the corrective action for each

Walk through a plan review checklist in order: scope, fixtures, supply, drainage, venting, and backflow protection

Describe the inspection sequence from rough-in to final and list what a cross-connection inspector verifies at each stage

Explain how to document a backflow test result, including gauge calibration records and reporting to the water authority

Identify the most common plan review rejection reasons and how to preempt them

Outline the enforcement workflow from violation notice through re-inspection, including escalation and appeals

Explain the inspector's authority, liability boundaries, and ethical obligations during enforcement actions

Describe confined space, lockout, and PPE hazards encountered during plumbing and backflow inspections

Draft a violation notice for a scenario with an unprotected cross-connection, citing the requirement and the correction deadline

Assemble a single-page formula and definition sheet covering fixture units, slope, trap seal depth, and pressure limits

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

Re-study the two lowest-scoring domains using your own notes and diagrams only

Recite the backflow assembly types, their hazard ratings, and testing intervals from memory without reference
