Lesson Overview
While plastics are widely used across modern plumbing systems, exposure to heat, light, oxygen, and ultraviolet radiation can cause them to deteriorate and fail prematurely. Understanding how plastics degrade enables plumbers to select the correct materials and install adequate protection on site.
Learning Objectives
Identify the four primary causes of plastic degradation in plumbing installations.
Explain the specific effects of thermal, photo, oxidative, and ultraviolet degradation on common plumbing plastics.
State practical on-site protection methods and regulatory limits used to prevent plastic deterioration.
