GA Plumber study plan

Trace the water service from meter to the farthest fixture on three practice layouts, labeling every segment by size and material

Compute supply fixture-unit loads for a one-bath and a two-bath dwelling using the code fixture-unit tables

Convert those same layouts to drainage fixture units and select branch and building-drain sizes

Verify required slope for every drain segment sized and mark each location where a cleanout is mandated

Reconcile any conflict between the fixture-unit total and the minimum pipe size rule for each line

Select pipe and fitting materials for a residential system and defend each choice against the code's permitted-use and prohibited-use lists

Size a distribution main and branches for a 2.5-bath dwelling using demand load and allowable pressure loss

Lay out the vent system for a bathroom group, naming each vent by type and stating its connection point

Size each individual vent and the vent stack from the fixture-unit tables and check the result against minimum-size rules

Identify every place where a vent must increase in size or where a relief vent is triggered

Match a described remodel scenario to the correct scope and administrative provisions, listing the permit, inspection, and testing steps in order

Size a horizontal building drain and a stack for a multi-fixture commercial restroom from the drainage fixture-unit tables

Determine cleanout size, spacing, and access clearance for each drain run sized, including a horizontal-to-vertical change

State the code basis for each decision you made by section topic, not by memory alone

List five common drainage-sizing errors and the correction for each

Read five isometric drawings and write out for each the fixture-unit count, pipe sizes, and direction of flow

Sketch your own riser isometric from a floor plan showing drainage, vent, and water lines in correct relationship

Distinguish wet vent, common vent, circuit vent, and stack vent on practice diagrams and name the fittings used at each junction

Diagnose three failed vent conditions (flat vent, crown-vent relief absence, vent below the trap weir) and state the correction

Decode the plumbing symbols and abbreviations on a legend and redraw a plan using them consistently

Specify supply connection size, drain outlet size, and trim requirements for water closets, lavatories, and bathtub/shower units

Measure and verify minimum fixture clearances and access for a small bathroom layout, flagging each violation found

Size a temperature-and-pressure relief valve and its discharge pipe for a given heater input rating and state the termination rules

Explain thermal expansion control, strapping/seismic restraint, and combustion air requirements for a gas-fired water heater

Compare tank and tankless installations for venting, clearance, and condensate handling

Assign the correct trap type, seal depth, and size to every fixture in a practice building and flag each prohibited trap configuration

Choose an air gap, reduced-pressure principle device, or pressure vacuum breaker for four described cross-connection scenarios and state the required testing interval

Size an indirect waste receptor and set the air gap or air break distance for a commercial kitchen sink and dishwasher

Size roof drains, leaders, and the storm building drain for a given roof area and design rainfall rate

Separate which fixtures may and may not discharge to a storm or special waste system and justify each call

Build a timeline mapping each permit, inspection, and test requirement to the job stage where it applies

Size a gas piping system by the longest-length method for a range, water heater, and furnace, showing the demand in Btu/h at each appliance

State connector type, shutoff valve, sediment trap, and clearance requirements for each appliance sized

Verify combustion air and appliance venting provisions for a confined-space installation and note what must be added

Identify which code sections govern the plumbing-to-gas interface at a combination water heater

Assemble a personal tool and material checklist for rough-in and service tasks and use it on one mock job walk-through

Write out the hydrostatic and DWV air test procedures, including test pressures, hold times, and who witnesses the test

Complete two full-length timed practice exams and trace every missed question back to its code section

Re-drill the three weakest subtopics identified at week 4 until each is scored at 90% or better

Build a one-page formula and table index you can rebuild from memory on exam day
