What is meant by 'plumbing' in the context of the Building Code Act?

The term 'plumbing' in the context of the Building Code Act specifically refers to the systems involved in the transportation of liquids, notably water, and the removal of wastewater. This definition encompasses the drainage system, which is responsible for the removal of sewage and stormwater; the venting system, which allows air to circulate within the drainage system and prevents the buildup of harmful gases; and the water system, which delivers potable water to various fixtures within a building.

Plumbing is essential for ensuring the health and safety of occupants by providing access to clean water and effectively removing waste. The focus on drainage, venting, and water systems illustrates the comprehensive nature of plumbing as it relates to building safety and sanitation requirements in the Ontario Building Code.

In contrast, the other options pertain to different systems not classified under the plumbing category. Heating systems relate to climate control, roofing systems focus on building covers and their drainage capabilities, and structural frameworks pertain to the integrity and support of the building itself. Each of these aspects is critical to building performance and safety, but they do not fall under the specific definition of plumbing as recognized by the Building Code Act.
