ASSE 5150 study plan

Map the scope and structure of the plumbing and mechanical code so you can locate any requirement for materials, joints, and fittings within two minutes

Define and distinguish potable water, nonpotable water, and the terminology used for pressure, flow, and fixture demand

Compute fixture-unit values for a mixed-occupancy building and convert them into estimated demand in gallons per minute

Identify the required minimum pipe sizes and the sizing method used for a water service and building supply main

Explain the difference between a public water main, a private service, and a building distribution system

Size a cold and hot water distribution system for a two-story building using the applicable tables and friction-loss method

Calculate the pressure available at the most remote fixture and check it against the required residual pressure

Describe how thermal expansion, water hammer, and pressure-reducing valves are addressed in design

Define cross-connection, backflow, backsiphonage, and backpressure with a written example of each

Classify the types of backflow prevention assemblies and state where each is required

Convert fixture units to drain pipe sizes and verify slope requirements for horizontal branches and building drains

Determine vent pipe sizes and identify where a vent stack, stack vent, and circuit vent are each permitted

Explain trap seal protection and the conditions that require a relief vent

Identify the situations that mandate a reduced-pressure principle assembly versus a double check valve assembly

Describe testing requirements for backflow assemblies and the responsibilities of the tester and the owner

Size storm drainage conductors, leaders, and gutters using rainfall intensity data and roof area calculations

Compute roof drainage area for flat, pitched, and combined roofs including vertical wall contributions

List the inspection stages required for underground rough-in, rough-in, and final inspection

Write the sequence of a hydrostatic drain test and a water distribution pressure test with required pressures and durations

Identify the items a plan reviewer checks on a submitted plumbing drawing set

State the minimum fixture clearances, spacing, and installation requirements for water closets, lavatories, and bathtubs

Explain the venting, combustion air, and temperature and pressure relief requirements for water heaters

Identify the materials permitted for fixture fittings and the lead-free requirements for wetted surfaces

Perform a plan review of a sample residential plumbing plan and log every deficiency against a specific code section

Prepare a correction notice that cites the code section, describes the condition, and states the corrective action

Describe the permit application process, the information required on submittals, and the conditions under which a permit may be issued

Explain the authority of the inspector, the right of entry, and the process for stop-work orders

Distinguish between a variance, an alternative method, and a code modification and state who approves each

Outline the certificate of occupancy and final approval sequence for a plumbing installation

Apply the adopted code edition and local amendments to a scenario involving conflicting requirements

Identify the special plumbing systems covered by the code, including medical gas, fuel gas piping, and gray water reuse

State the safety requirements for traps, cleanouts, and access for maintenance in concealed spaces

Explain the material standards and marking requirements for pipe, fittings, and solder

Describe the requirements for protecting potable water from contamination during construction and repair

Apply the administration provisions to a complaint investigation and document the findings

Complete a full-length timed practice examination and score it by domain

Review every missed question and trace the governing code section for each

Re-drill the weakest two domains with focused problem sets until accuracy exceeds eighty percent

Recite the key numerical thresholds, clearances, and test pressures from memory

Build a final one-page summary sheet of the most testable code provisions
