Water Main Repair in Duncan, BC
Repair of the private water service, from the municipal main to the house, for Duncan and North Cowichan homes on city water.
Local plumbing context for Duncan
Inside the City of Duncan and the connected North Cowichan neighbourhoods, homes are on municipal water and sewer, and sewage goes to the Joint Utilities Board treatment lagoons shared by Duncan and North Cowichan. Duncan's housing is older than the Cowichan Valley average, with 30% built before 1961 and another 32% between 1961 and 1980, so most in-town homes predate Poly B; we find it mainly in 1980sā90s builds and renovations around the city. The plumbing permit depends on the address. The City of Duncan, the Municipality of North Cowichan, and the Cowichan Valley Regional District each issue permits inside their own boundaries. We pull the permit for the jurisdiction the property is in, schedule the inspection, and hand you the signed-off certificate when we finish.
The line we are talking about
When someone in Duncan says the water main is leaking, they usually mean the private service pipe between the municipal stop and the house, not the city's watermain in the street. Inside the City of Duncan and the connected North Cowichan neighbourhoods that pipe is fed by municipal water. A wet strip in the lawn, a meter that turns while every tap is shut, or a sudden loss of pressure are the usual signs.
Older in-town houses ā 30% of Duncan's housing was built before 1961 ā often still have galvanized or early copper services. Newer North Cowichan streets, including areas such as Bell McKinnon, are typically plastic from the main to the house. We do not guess from the decade. We look at what is visible at the meter and at the entry to the mechanical room, then pressure-test.
Soft water and the repair
The City of Duncan's 2022 water report lists hardness around 25 mg/L. That is soft water, so a pinhole in a galvanized service is not a scale problem the way it is in a hard-water town. The pipe has simply reached the end of its life. We replace the failed section, or the whole service when the test shows the rest of the metal is thin, and we pressure-test before we backfill.
The plumbing permit is issued by the City of Duncan, the Municipality of North Cowichan, or the Cowichan Valley Regional District, matching the address. Work in the boulevard needs that jurisdiction as well. If the leak is actually on the indoor supply and the pipe is grey plastic, read Poly B replacement in Duncan before we dig the yard. Request an appointment with the address and a photo of the meter.

No. We repair the private service from the municipal connection to the house. A break in the street main is the water utility's job.
Soft water does not stop an old galvanized or copper service from wearing out. Duncan's 2022 report puts hardness around 25 mg/L, so we look at age and the pipe material, not scale.
