Identify and Advise on Efficient Solar Heated Water Design and Installation

This unit specifies the competency required to develop skills in effectively managing existing resources, increasing sustainability through water and energy efficient products and practices.

Plumbers are in direct contact with end users on a daily basis. A clear understanding of existing water efficient products, emerging technologies, best management practices and existing conservation programs is essential in fostering conservation, developing partnerships with local water utilities and authorities, and increasing business opportunities.
Work associated with this unit is undertaken within the plumbing and services sector in accordance with relevant US standards.

Nominal Hours - 4
