Lead Water Pipe Replacement in Toronto
Upgrade Your Underground Water Line for Safer, Cleaner Water
Many older homes across Toronto—including East York and Etobicoke—still rely on outdated lead water service pipes as their main water supply. While these pipes may not always leak, they can introduce harmful contaminants into your drinking water.
Lead exposure is widely linked to serious health risks, making replacement one of the most important upgrades for homeowners. Replacing your underground water line with modern, code-approved materials like copper ensures a safer and more reliable water supply.
At Mister Plumber, we specialize in lead water pipe replacement in Toronto, completing hundreds of upgrades every year using efficient, minimally invasive methods.
Understanding Your Water Service Line in Toronto
Each home has a dedicated underground water line that connects from the municipal water main to your basement, where the main shut-off valve and water meter are located.
This water line is divided into two sections:
- City-owned portion (from the water main to property line)
- Private portion (from property line into your home)
Homeowners are responsible for replacing the private side of the water line.
The City of Toronto offers a lead pipe replacement program that may cover the city-owned section. However, to complete the process, homeowners must upgrade their portion using a licensed Toronto plumber and provide proper documentation.
Our Trenchless Lead Pipe Replacement Process
We use advanced trenchless (torpedo drilling) technology to replace underground water lines with minimal disruption to your property.
How it works:
- A small access point is created near the property line
- A controlled opening is made near the water meter inside the basement
- Specialized equipment creates an underground channel between the two points
- A new copper water line is installed through this channel
- The old lead pipe is safely disconnected and abandoned underground
- A new main shut-off valve is installed
- All openings are restored, including concrete and landscaping areas
Most projects are completed within one day
Water service is typically restored the same afternoon
This method avoids major excavation—especially beneficial for homes with front porches, landscaping, or limited access.
What Affects the Cost of Lead Pipe Replacement?
The price of replacing a lead water line can vary depending on several factors:
- Length of the private water line
- Depth of the existing pipe
- Soil conditions and ground obstacles
- Location of the water meter
- Accessibility inside the basement
- Required pipe size and layout
Because every property is different, an on-site assessment is the best way to provide an accurate estimate.
Choosing the Right Pipe Size
Older lead pipes are typically 1/2 inch in diameter, which no longer meets modern standards.
According to Ontario plumbing code:
- Minimum size for residential homes: 3/4 inch
- Most homes are upgraded to 3/4 inch copper
- Larger homes may require 1 inch service
When to consider a 1-inch water line:
- Homes with 4–5+ bathrooms
- Properties with basement apartments or rental units
- Houses with irrigation systems or pools
Upgrading to a larger pipe can significantly improve water pressure and flow. The city may also upgrade its portion to match for an additional fee.
