8 weeks · About 7 hours per week
Cold Water Supply and Storage Systems & Occupational Health, Safety and Environment
Draw and label a complete cold water supply schematic for a two-storey house, showing service pipe, storage tank, distribution pipe, and draw-off points, from memory without notes.
Calculate storage tank capacity and daily demand for a four-person household using 120 litres per person per day, and justify the tank size chosen in writing.
List the PPE required for five named plumbing tasks (pipe threading, solvent welding, working at height, trench work, hot work) and state the specific hazard each item controls.
Demonstrate correct manual handling and ladder-set-up rules by writing a six-step safe procedure for carrying a 6 m galvanised pipe up a ladder.
Your checkpoint
A hand-drawn cold water supply schematic with a one-page calculation sheet showing tank capacity, pipe sizes assumed, and demand figures.
Cold Water Supply and Storage Systems & Occupational Health, Safety and Environment
Explain in writing how a cold water storage cistern and a direct mains system differ in pressure behaviour, and state two building types suited to each.
Describe the purpose and correct setting of a float valve (ball valve) and list four symptoms of a faulty one with the repair for each.
Identify the causes of water hammer and airlock in a cold supply and write the diagnostic sequence you would follow to isolate each.
Outline the statutory and site requirements for safe drinking water storage, including cistern covering, screening, and separation from waste pipes.
Your checkpoint
A fault-finding table of at least eight cold water supply faults, each with symptom, likely cause, test method, and remedy.
Tools, Equipment, Materials and Pipework Fundamentals & Pipe Bending, Jointing and Fabrication
Match 15 named plumbing tools to their correct use, and state the maintenance routine for five of them.
Compare four pipe materials (PVC, PPR, galvanised steel, copper) on pressure rating, joining method, cost, and typical application, in a written table.
Describe the full solvent-welding procedure for PVC pipe, including cutting square, deburring, applying primer and cement, and the curing time before pressure testing.
Explain how to make a threaded joint on galvanised pipe, including thread length, use of hemp or PTFE tape, and tightening turns.
Your checkpoint
A pipe materials and jointing comparison table covering at least four materials and three joint types, with a written step list for each joint type.
Pipe Bending, Jointing and Fabrication & Sanitary Plumbing, Drainage and Waste Systems
Calculate the developed length and bend allowance for a 90-degree bend on a 50 mm pipe using a stated bend radius, showing all working.
Describe how to set out and cut a 45-degree offset between two fixed points, including the measurement method and marking.
Sketch a single-stack drainage layout for a two-storey building showing soil pipe, waste pipe, vent pipe, gully, and inspection chamber, with correct fall arrows.
State the minimum falls for 50 mm, 75 mm and 110 mm drainage pipes and explain why excessive fall is as problematic as insufficient fall.
Explain the function of a trap seal, the correct seal depth, and two ways a trap seal can be lost.
Your checkpoint
A dimensioned drainage layout sketch plus a calculation sheet for one 90-degree bend and one 45-degree offset with developed lengths shown.
Sanitary Plumbing, Drainage and Waste Systems & Sanitaryware, Fixtures and Appliance Installation
Describe the installation sequence for a WC pan, wash basin, and shower tray, listing the setting-out, fixing, and sealing steps for each.
Explain the difference between a P-trap and an S-trap and state where each is appropriate, including the risk of self-siphonage.
List the tests used to check a drainage installation (air test, water test, smoke test) and state the acceptance criteria for each.
Describe how to connect an appliance such as a washing machine or water heater to the waste and supply system with correct backflow protection.
Your checkpoint
A written installation guide of at least 400 words for fitting a WC suite and wash basin, covering setting out, fixing, sealing, and testing.
Technical Drawing, Sketching and Trade Calculations & Tools, Equipment, Materials and Pipework Fundamentals
Produce a neat isometric sketch of a simple pipe run and convert it to a orthographic plan view.
Read a simple plumbing drawing and extract a material take-off list with quantities and sizes.
Calculate pipe volume, tank volume, and the weight of a filled pipe run using given dimensions and densities.
Use the 3-4-5 method to set out a right angle on site and explain when this is preferred to a try square.
Your checkpoint
A material take-off sheet derived from a self-drawn isometric pipe layout, with all quantities and calculations shown.
Maintenance, Fault Diagnosis and Repair & Entrepreneurship, Costing and Customer Care
Diagnose five common plumbing faults (leaking tap, running cistern, blocked trap, low pressure, noisy pipe) with a written test sequence for each.
Prepare a costing for a small repair job including labour hours, materials, transport, and a stated profit margin.
Write a quotation and a simple invoice for a repair job, including scope, terms, and payment conditions.
Draft a customer care script for arriving at a client's premises, explaining a fault, and handling a complaint about cost.
Your checkpoint
A complete job pack for one repair scenario: diagnosis notes, priced quotation, invoice, and a customer communication script.
Professional Practice, Ethics and Workplace Communication & Maintenance, Fault Diagnosis and Repair & Occupational Health, Safety and Environment
State five professional and ethical obligations of a plumber, including confidentiality, honest pricing, and safe disposal of waste.
Explain the correct procedure for reporting a workplace accident and for refusing unsafe work.
Complete a timed 60-question mixed mock covering all ten domains and record the score per domain.
Review every mock question answered incorrectly and write a one-line correction note for each.
Your checkpoint
A scored mock exam record with a per-domain breakdown and a personal list of weak areas with revision actions.
Milestones
