ICC P1 study plan

Map the IPC administrative sequence - permit application, plan review, rough-in inspection, final inspection - into a one-page flowchart keyed to specific section numbers.

Classify ten common materials and methods as listed, labeled, or requiring alternate-materials approval, citing the section that governs each one.

Compile a table of the standards adopted by reference, noting which edition of each standard applies and where it is invoked in the body of the code.

Work 20 permit, inspection, and approval scenarios and annotate every miss with the exact section that resolves it.

Size a cold-water branch line end-to-end using the fixture-unit table, developed-length method, and pressure-loss tables, showing each calculation step.

Verify residual pressure at the most remote outlet for three layouts and adjust pipe diameter until each one passes.

Identify every location on those layouts where backflow protection is required, then match each hazard to an approved device type.

Sequence the hydrostatic test for new water piping, stating test pressure, hold duration, allowable leakage, and who witnesses it.

Tabulate approved pipe, fitting, and joint methods for at least five water distribution materials, including solvent cement and press connections.

Calculate drainage fixture units for a two-story layout and convert the total to building drain and building sewer size using the drainage tables.

Assign slope, cleanout spacing, and change-of-direction rules to each horizontal branch and justify every choice with a citation.

Locate where backwater valves, sump pumps, and subsoil drains are mandatory on the same layout.

Describe the water or air test of the drainage system - hydrostatic head, duration, and acceptance criteria - in inspection-ready language.

Compare five prohibited fittings and fitting patterns against the approved drainage fittings they are commonly confused with.

Determine the maximum trap-to-vent distance for every fixture on your isometric at both 1/4 inch and 1/8 inch per foot slope.

Size a vent stack and stack vent from a stated fixture-unit load using the vent sizing tables.

Differentiate wet vent, common vent, circuit vent, and air admittance valve applications and state the limits on each.

Draw five venting details, three compliant and two defective, and write the inspection correction for each defect.

Compute minimum fixture counts for a restaurant and an office using occupant load and the minimum fixture ratio table.

Verify clearance, privacy, and mounting-height dimensions for water closets, lavatories, and urinals against the code and the referenced accessibility standard.

Specify installation requirements for floor drains, drinking fountains, and dishwashing equipment in a written inspection note.

Confirm fixture-unit values and trap sizes for ten common fixtures and flag any mismatch between the trap size and the fixture outlet.

Trace the temperature-and-pressure relief valve discharge path from valve to termination and list five installation errors that would fail inspection.

Size combustion air openings for a water heater in a confined space using the two-permanent-opening method.

Apply seismic strapping, drain pan, and clearance-to-combustibles requirements to a hand-drawn heater installation sketch.

Verify trap seal depth, trap arm length, and prohibited trap configurations across five plumbing details.

Size a grease interceptor from a stated fixture load and describe its flow-control fitting and venting requirements.

Size roof drains, leaders, and the building storm sewer for a given roof area and rainfall rate, including the secondary drainage system.

Determine scupper, overflow, and trapped-versus-untrapped roof drain requirements for a flat-roof detail.

Size a fuel gas branch line with the longest-length method for both natural gas and liquefied petroleum gas at the same appliance load.

Specify sediment trap, shutoff valve, union, and connector locations for a gas appliance connection on a sketch.

State the pressure test requirements for fuel gas piping at medium and high pressure, including test medium and hold time.

Complete three timed 60-item practice exams and log every miss by domain and code section.

Re-study only the domains that scored below 80%, reworking each missed item to a corrected answer with a citation.

Rebuild the Week 1 permit-and-inspection flowchart from memory and reconcile every difference against the original.

Assemble a one-page index of the 40 most frequently missed citations for a final pass the morning of the exam.
