A water service upgrade replaces the pipe that connects a property to the municipal water main. Older properties in Toronto and the GTA commonly have lead or galvanized steel water service pipes that reduce water pressure, restrict flow, and, in the case of lead, pose a health risk. Upgrading resolves all three issues.
Health Canada identifies lead water service pipes as a significant source of lead exposure in older Canadian homes, particularly in properties where the service pipe predates the 1970s prohibition on lead in plumbing materials. The risk is highest when water sits in the pipe overnight.
Signs a Water Service Upgrade Is Needed
Visibly low water pressure that affects multiple fixtures simultaneously often indicates a restricted or corroded service pipe. Discolored water, particularly rust-colored flow when taps are first opened, suggests internal pipe corrosion. A plumber can determine whether the issue originates in the service line or the internal plumbing.
Properties undergoing renovations that increase water demand, such as adding bathrooms or an irrigation system, may find that the existing service pipe diameter is insufficient. A service upgrade at the time of renovation is more cost-effective than addressing it after the renovation is complete.
The Upgrade Process
City of Toronto water service upgrade programs provide financial assistance for homeowners replacing lead water service pipes. The program covers the homeowner’s portion of the pipe from the property line to the home. The city replaces the municipal portion simultaneously.
For professional water service upgrade services in Toronto and the GTA, licensed plumbers can assess the existing service, handle permit requirements, and complete the replacement.
