Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Basic tests mayinclude:
bucket test
meter test
pump on/pump off test
water loss calculations.
Leak-detection equipment and materials may include:
bucket
communication systems
dye
electronic water loss calculators
hand and power tools
leak-detection equipment:
listening devices
pressure testing
vinyl liner leak detector
personal protective equipment
pipe locating equipment
portable pumps.
Related services may include:
electricity
gas
sewerage
stormwater
water supply.
Leak-detection process mayinclude:
conduct pressure test of plumbing lines
confirm leaks by analysing information gathered through conducting basic tests
identify underground plumbing leaks
inspect fittings and cracks in pool structures
pinpoint leaks in vinyl liner.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
This unit of competency could be assessed by detecting leaks and arranging relevant repairs in swimming pools and spas.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person should demonstrate the ability to:
plan leak-detection activities, including conducting basic water loss tests to confirm leaks in swimming pools and spas
operate leak-detection equipment
comply with safety requirements when conducting leak-detection activities
detect leaks and arrange relevant repairs in swimming pools and spas
record and report on leak-detection activities.
Context of and specific resources for assessment
Assessment of essential underpinning knowledge may be conducted in an off-site context and is to comply with relevant regulatory and Australian Standards’ requirements.
Resource implications for assessment include:
relevant codes, standards and government regulations
a technical reference library with current publications on leakdetection techniques for swimming pools and spas.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the CPP07 Property Services Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm that competency is verified and able to be transferred to other circumstances and environments.
This unit could be assessed on its own or in combination with other units relevant to the job function.
Guidance information for assessment
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
