Detect leaks in swimming pools and spas

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency specifies the outcomes required to plan leak-detection activities and to locate, identify and report leaks in swimming pools and spas. It includes operating leak-detection equipment, and recording and reporting on leak-detection activities.

The unit supports the work of those engaged in installing, servicing and repairing domestic, commercial and public swimming pools and spas. It applies to swimming pool and spa technicians.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Assessor requirements

As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
