The codes of practice attempt to minimize public risk by specifying technical standards of design, materials, workmanship and maintenance for plumbing systems. The main aims of the code are:

• To ensure that planners, administrators and plumbers develop the required competency to ensure that the codes are applied and upheld
• That standards are set to ensure that plumbing assemblies, materials and technologies are safe and effective;
• To ensure that plumbing installations meet these standards
• To ensure safety and effectiveness continuously through the proper maintenance of these installations
