Water Service Line Repair and Replacement

Signs the Service Line Is the Problem

The water service line is the buried pipe that carries water from the municipal connection at the street into your home. When it starts failing, the symptoms usually show up as a whole-property problem rather than at one fixture: pressure drops everywhere at once, the meter keeps moving when every tap is closed, or a patch of lawn stays wet and green through a dry stretch.

Age and material matter. Galvanized steel lines corrode and narrow from the inside, which is why an older property can have acceptable pressure at the street and poor pressure at the fixtures. Polybutylene service lines carry the same internal degradation problem as Poly-B inside the house. Either way, the diagnosis starts by separating a supply-side problem from an internal plumbing problem before anything gets excavated.

• Low pressure at every fixture, not just one
• Water meter registering flow with all fixtures off
• Wet or unusually green ground along the line route
• Discoloured water at first draw from an aging galvanized line
• An unexplained jump in the water bill

Where Your Responsibility Starts

Municipalities in Metro Vancouver generally maintain the water main and the connection up to a defined point, commonly at or near the curb stop or the property line, and the owner is responsible for the line from there into the building. The exact boundary is set by local bylaw and differs between Surrey, Vancouver, Burnaby, and the rest, so it is worth confirming before assuming the repair is yours.

That boundary matters for cost and for scheduling. Work on the municipal side is coordinated with the city; work on the private side is yours to permit and complete. We identify which side the failure is on before the quote, so you are not paying to excavate a section that the municipality would have handled.

Open-Cut or Trenchless

Open-cut excavation means trenching along the line route, which is straightforward and usually the most economical approach when the run is short and nothing significant sits on top of it. Trenchless replacement pulls a new line through the existing path from entry and exit pits, which limits surface disruption when the route crosses a driveway, mature landscaping, or hardscaping you would rather not rebuild.

Neither method is automatically better. The deciding factors are the length of the run, soil and groundwater conditions, what is on the surface, and whether the existing path is intact enough to pull through. We assess the route and give you the actual trade-off for your property, including what restoration each option leaves behind.

Permits, Inspection, and Restoration

Service line replacement is permitted work. It typically involves a municipal plumbing permit, coordination for the shutoff at the curb stop, and inspection before the trench is backfilled. If the route crosses a boulevard, sidewalk, or road allowance, additional municipal approvals apply and those approvals drive the schedule more than the plumbing does.

Restoration is the part homeowners most often underestimate. Excavation across a lawn, driveway, or paved area leaves work behind that the plumbing scope may not include. We identify what restoration each approach requires up front so the full picture is priced before the first cut, not discovered after backfill.
