RBSE Sec Voc Plumbing study plan

RBSE Sec Voc Plumbing · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Trade Fundamentals, Tools, Materials and Safety & Water Supply Systems: Pipes, Fittings and Installation

  • Identify and name at least 25 hand and power tools used in plumbing, stating the specific task each performs.

  • Classify common pipe materials (GI, CI, PVC, CPVC, HDPE, copper, PPR) by pressure rating, joining method and typical application, without notes.

  • Read pipe sizing tables for a simple supply layout and select correct diameters for a bathroom group and a kitchen line.

  • List the PPE and site-safety rules that apply before starting any pipe installation task.

Your checkpoint

A one-page tool-and-material reference sheet plus a solved pipe-sizing exercise for a two-bathroom layout, checked against sizing tables.

Week 2

Water Supply Systems: Pipes, Fittings and Installation & Plumbing Fixtures, Fittings and Appliances

  • Draw and label a direct and an indirect cold-water supply system showing overhead tank, distribution pipe and branches.

  • Describe the function of gate valve, ball valve, check valve, pressure-reducing valve and air vent, and state where each is fitted.

  • Match at least 15 fixtures and fittings (bib cock, pillar cock, flush valve, ball float, mixing tap, shower rose) to their location and purpose.

  • Explain how a geyser or electric water heater is connected to the supply line, including the safety valve position.

Your checkpoint

Annotated schematic of a full house water supply system with all valves and fixtures labelled, plus a fixture-to-application matching table of 15 items.

Week 3

Sanitary Drainage, Soil and Waste Systems & Sanitary Fixtures, Traps and Venting

  • Trace a soil and waste drainage layout from water closet to inspection chamber, naming each pipe, fitting and gradient.

  • Calculate the required fall for a 4-inch drain over a 12-metre run at the standard gradient.

  • Explain the purpose of a trap, a vent pipe, an anti-siphon arrangement and an inspection chamber, and state the code-based spacing rules you have studied.

  • Sketch a P-trap, an S-trap and a bottle trap and state where each is permitted or prohibited.

Your checkpoint

A scaled single-line drainage plan of a two-storey house showing stacks, vents, traps and two inspection chambers, with gradients computed and written on the drawing.

Week 4

Sanitary Drainage, Soil and Waste Systems & Sanitary Fixtures, Traps and Venting & Water Storage, Tanks and Pumps

  • Size a domestic overhead and underground tank for a stated daily demand and justify the capacity chosen.

  • Compare centrifugal, submersible and jet pumps by head, application and installation position.

  • Describe the correct sequence for installing a pump with foot valve, suction line and pressure switch.

  • Explain how venting prevents trap seal loss, using the concept of air pressure equalisation in your own words.

Your checkpoint

A timed 40-question self-test covering Domains 4, 5 and 6, scored and reviewed with every wrong answer corrected in writing.

Week 5

Soldering, Brazing, Welding and Pipe Joining & Trade Fundamentals, Tools, Materials and Safety

  • Demonstrate or describe step by step the soldering of a copper joint: cutting, deburring, fluxing, heating and applying solder.

  • State the correct flux, filler and temperature range for soldering versus brazing copper pipe.

  • List the safety precautions for hot work, including fire watch, cylinder handling and ventilation.

  • Explain solvent cementing of PVC and threading of GI pipe, including the number of turns and dope application.

Your checkpoint

A written joint-procedure card for four joining methods (solder, braze, solvent weld, threaded) with temperatures, materials and safety steps, plus a practice joint photo log if workshop access is available.

Week 6

Drawing, Estimating, Costing and Measurement & Repair, Maintenance and Leak Detection

  • Take off quantities of pipe, fittings and fixtures from a given plumbing drawing and prepare a material schedule.

  • Compute a cost estimate including material, labour and overhead for a small bathroom installation.

  • Describe at least five leak-detection methods (pressure test, dye test, acoustic, moisture meter, visual inspection) and when each is used.

  • Outline the repair procedure for a leaking float valve, a dripping tap and a cracked PVC joint.

Your checkpoint

A complete estimate sheet for a bathroom plumbing job with quantities, rates, labour and total cost, plus a leak-repair procedure list of five methods.

Week 7

Workplace Safety, Environment and Entrepreneurship & Plumbing Fixtures, Fittings and Appliances

  • List the statutory and site safety requirements for plumbing work, including excavation, confined space and electrical safety near water.

  • Describe safe handling and disposal of lead, solvent cement and asbestos-cement pipe waste.

  • Explain the basic elements of running a small plumbing enterprise: quotation, licence, record keeping and customer service.

  • Revisit fixture and appliance installation errors and state the correct practice for each.

Your checkpoint

A two-part document: a workplace safety checklist of at least 15 items and a one-page small-business start-up note covering licence, pricing and record keeping.

Week 8

Trade Fundamentals, Tools, Materials and Safety & Water Supply Systems: Pipes, Fittings and Installation & Sanitary Drainage, Soil and Waste Systems & Sanitary Fixtures, Traps and Venting & Water Storage, Tanks and Pumps & Soldering, Brazing, Welding and Pipe Joining & Drawing, Estimating, Costing and Measurement & Repair, Maintenance and Leak Detection & Workplace Safety, Environment and Entrepreneurship & Plumbing Fixtures, Fittings and Appliances

  • Complete two full-length timed mock exams under exam conditions and score each.

  • Review every incorrect answer and map it back to its domain and study week.

  • Re-drill the two weakest domains with targeted questions until accuracy exceeds 80 percent.

  • Recite key numbers (gradients, trap seal depth, vent distances, tank sizing, solder temperatures) from memory.

Your checkpoint

A final revision log showing both mock scores, error-domain breakdown and a signed statement that all weak areas were re-tested above 80 percent accuracy.

Milestones

Week 2: Can draw and explain a complete cold-water supply system and correctly match 15 fixtures to their applications without notes.

Week 4: Scores at least 70 percent on the 40-question Domain 4/5/6 self-test and has corrected every wrong answer in writing.

Week 6: Produces a full material take-off and cost estimate for a bathroom job that balances and matches quantities to the drawing.

Week 8: Scores at least 80 percent on both full-length mock exams, with no domain below 70 percent.
