Navigating the 2024 Ontario Building Code (OBC) is essential for ensuring the longevity and safety of your property's plumbing and drainage infrastructure. As empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize compliance with Section 7.2.5 to deliver high-quality non-metallic piping solutions.
7.2.5.1 and 7.2.5.2: Standards for Fibrocement and Concrete Piping
The OBC mandates that fibrocement pipes for drain, waste, or vent systems must conform to CAN/CSA-B127.3. For concrete piping, the code is even more stringent: pipes must meet CSA A257 standards, and on-site fabrication of fittings is strictly prohibited to ensure structural integrity. Notably, concrete pipe is restricted from being used above ground inside any building.
7.2.5.3 and 7.2.5.4: Vitrified Clay and Polyethylene Specifications
Vitrified clay pipe remains a reliable choice for underground drainage, provided it meets CSA A60.1-M standards. However, its use is strictly limited to underground applications. For water services, Polyethylene (PE) pipe must meet a pressure rating of Series 160 or higher (CSA B137.1). Except for specific exceptions, PE water pipe is reserved solely for water service pipe applications.
7.2.5.5: Advanced Underground Rehabilitation with Trenchless Technology
Modern construction often involves the rehabilitation of existing systems. Section 7.2.5.5 specifies that polyethylene pipe used for trenchless technology rehabilitation must conform to ASTM F714 and utilize HDPE 3408 (SDR 17 or heavier). This ensures that updated drainage systems can withstand the stresses of installation and long-term use without the need for extensive excavation.
