Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a thorough risk assessment prior to commencing any plumbing repair work, identifying hazards such as water leaks, electrical sources, and hazardous substances, and implementing appropriate control measures.
- Award credit for correctly selecting and safely using personal protective equipment (PPE) including safety goggles, gloves, and steel-toe boots throughout the repair process.
- Award credit for accurately isolating the water supply and safely draining the system before beginning repair or replacement of plumbing components.
- Award credit for effectively diagnosing common faults in plumbing fittings, wastes, and sanitary appliances, and justifying the chosen repair or replacement method.
- Award credit for demonstrating competent practical skills in repairing a leaking tap, replacing a damaged waste trap, and fixing a toilet cistern mechanism, ensuring all work is leak-free and compliant with water regulations.
- Award credit for demonstrating correct isolation of water supply and safe discharge of residual pressure before starting work.
- Award credit for selecting and using appropriate PPE (gloves, eye protection, overalls) and maintaining a tidy, hazard-free work area throughout the task.
- Award credit for accurately measuring, cutting, and joining pipework using appropriate materials and techniques, with clear evidence of leak-free connections.
- Award credit for effectively diagnosing faults in sanitary appliances (e.g., worn washers, faulty ball valves) and implementing secure, lasting repairs.
- Award credit for performing a thorough post-repair check, including leak testing and functionality verification, and leaving the site clean.
Assessment Guidance
Guidance for achieving higher grades
- 💡When preparing for practical assessments, practice isolating various types of stopcocks and isolating valves, as this is a fundamental safety step that examiners will closely observe.
- 💡Familiarise yourself with the Water Supply (Water Fittings) Regulations 1999 and how they apply to repairs and replacements; referencing these in your written work demonstrates underpinning knowledge.
- 💡In your portfolio, include annotated photographs of before, during, and after repairs to provide clear evidence of your competence and to highlight safety measures taken.
- 💡During knowledge-based assessments, pay attention to the correct terminology for plumbing components (e.g., ‘ball valve’ vs ‘float valve’, ‘trap’ vs ‘waste’), as precise language is often required for marks.
- 💡In practical assessments, verbalize your safety checks (e.g., ‘I am now isolating the water supply and testing the isolation’) to demonstrate knowledge even if the outcome is observed.
- 💡For written tasks, explicitly reference relevant health and safety legislation (e.g., COSHH, Water Regulations) and industry codes of practice to show depth of understanding.
- 💡Practice replacing a variety of common components—syphon diaphragms, ball valves, trap seals—under timed conditions to build speed and confidence for synoptic tests.
- 💡Tip 1: Always link your practical work to health and safety. In assessments, explicitly mention the PPE you used, the risk assessment you carried out, and how you disposed of waste. This shows you understand the professional standards required.
- 💡Tip 2: Use the correct terminology for tools and materials. For example, say 'plasterer's hawk' instead of 'hand board' and 'float and set' instead of 'smooth the plaster'. This demonstrates your technical knowledge and helps you score higher marks.
- 💡Tip 3: When completing your portfolio, take clear photos of each stage of your work and write detailed annotations explaining what you did and why. This evidence is crucial for proving your competence to the assessor.
Common Mistakes
Common errors to avoid in your coursework
- Forgetting to turn off the water supply before attempting repairs, leading to flooding and water damage.
- Over-tightening compression fittings when repairing pipes, causing cracks or stripped threads that result in leaks.
- Using incorrect sealants or tapes on joints, such as applying PTFE tape on compression threads, which compromises the seal.
- Neglecting to check for electrical safety risks when working near wet areas, increasing the risk of electric shock.
- Failing to turn off the water supply at the mains or isolating valve before dismantling fittings, leading to uncontrolled leaks.
- Using the wrong type or size of washers, seals, or connectors, which results in improper seals and ongoing drips.
- Overtightening compression fittings or porcelain components, causing cracks or stripped threads that necessitate costly replacements.
- Neglecting to check and clear blockages fully before reinstalling wastes, so the problem persists despite replacing visible parts.
- Ignoring the need to apply pipe jointing compound or PTFE tape correctly, or using it on compression joints where it is not required, causing leaks.
- Misconception: You only need to know one trade to pass the diploma. Correction: The diploma is designed to make you multi-skilled, so you must demonstrate competence in at least three trades (e.g., carpentry, plumbing, and plastering) to meet the assessment criteria.
- Misconception: Health and safety is just common sense and doesn't need much study. Correction: Health and safety is a core part of the qualification and is rigorously assessed. You need to know specific regulations, such as COSHH and manual handling, and how to apply them in practice.
- Misconception: Refurbishment is just about making things look nice. Correction: Refurbishment involves structural repairs, ensuring building integrity, and complying with building regulations. Aesthetic improvements are only one part of the process.
