General Surface and Material Requirements
7.2.2.1. Surface Standards
Every plumbing fixture must feature a smooth, hard, and corrosion-resistant surface. This ensures that the fixture is free of flaws or blemishes that could harbor bacteria or interfere with effective cleaning and sanitation.
7.2.2.2. Conformance to Industry Standards
Fixtures must meet specific CSA and ASME standards based on their material composition:
- Vitreous China: ASME A112.19.2 / CSA B45.1
- Stainless Steel: ASME A112.19.3 / CSA B45.4
- Plastic & Composite: CSA B45.5 / IAPMO Z124
- Specialty Items: Hydromassage bathtubs and macerating toilet systems must comply with dedicated safety standards (CSA B45.10 and CSA B45.9).
Shower Installation and Drainage Rules
7.2.2.3. Structural Integrity and Layout
Shower receptors must be constructed to be completely watertight, preventing leaks into walls or subfloors. Key drainage regulations include:
- Drain Capacity: A single shower drain can serve a maximum of 6 shower heads.
- Water Flow Management: For multi-head installations, the floor must be sloped to prevent cross-flow between different shower areas.
- Spacing: Adjacent shower heads in a battery must be spaced at least 750 mm apart to ensure user comfort and proper drainage.
Specialized Requirements for Public and Food Service Areas
7.2.2.4. Concealed Overflows
To maintain hygiene and prevent the buildup of organic matter, dishwashing sinks and food preparation sinks are strictly prohibited from having concealed overflows.
7.2.2.5. Public Washroom Specifications
