Chapter 2: Material and Venting Requirements [07:19]

    • Corrosive waste materials must adhere to the materials specified by the national code.
    • The code demands that pipes used for venting corrosive waste extend to the outside, preventing internal stack corrosion.

Chapter 3: Fittings for Corrosive Waste [09:43]

    • Various fitting types, such as borosilicate glass and plastic options, are reviewed for use in corrosive waste plumbing.
    • Details on joining methods for materials like polypropylene, PVDF, and glass, highlighting their specific applications.

Chapter 4: Polypropylene Use and Building Requirements [14:38]

    • The restrictions on polypropylene use in unsprinklered buildings and its application in specific settings are discussed.
    • There’s a review of fire safety standards that apply to combustible materials in plumbing systems.

Chapter 5: Compliant Materials and System Requirements [17:03]

    • Emphasizes the importance of selecting materials suitable for corrosive waste that are compliant with building and plumbing codes.
    • Presentation touches upon the three acceptable options for Canadian DWV systems in corrosive applications.

Chapter 6: Neutralization versus Dilution [21:22]

    • Differentiation between neutralization and dilution as methods of treating corrosive waste, with a preference for the former.
    • A discussion of the municipal bylaws that dictate treatment methods before disposal into the sanitary system.

Chapter 7: Understanding pH and Its Implications [23:27]

    • The significance of pH levels in determining the acidity or alkalinity of waste and the inefficiencies of achieving neutral pH through dilution.
    • An explanatory point on the logarithmic nature of the pH scale and its relevance in neutralization processes.
