Water Service Line Replacement in Toronto
The water service line carries water from the City shut-off at the property line into your home. In older Toronto houses it is often undersized copper, galvanized steel or even lead, and it can corrode, leak underground or simply be too small for modern fixtures. POM Plumbing provides water line replacement and main water line repair across Toronto and the GTA, including trenchless water line replacement that avoids digging up your lawn, driveway and landscaping.
We handle the full job: locates, permits, excavation or trenchless boring, the new line, the main shut-off valve inside the house and coordination with the City of Toronto when the public side is also being replaced.

Water Line Replacement Process and Cost
How Water Line Replacement Works
- Inspection. We check the pipe material, size, depth and the route from the curb stop to the house.
- Quote and permits. You get a written price; we arrange locates and permits.
- Replacement. The new line is installed by trenchless method or open trench, depending on the site.
- Connection and testing. We connect to the City side, install a new main valve and pressure-test the system.
- Restoration. Pits and trenches are backfilled and the site is cleaned up.
Water Line Replacement Cost in Toronto
The cost depends on the length of the line, depth, soil and whether trenchless replacement is possible. Typical ranges:
| Service | Typical cost |
|---|---|
| Main shut-off valve replacement | from $450 |
| Main water line repair (one section) | from $1,500 |
| Trenchless water line replacement | from $5,000 |

City of Toronto Water Main & Lead Service Replacement
The City owns the pipe from the water main to the property line; the homeowner owns the part from the property line into the house. When the City replaces its side, replacing your side at the same time gives you a full new line and better pressure. We coordinate the timing and connection so your water is off for as short a time as possible.
