Plumbing in Nepean
"Nepean" covers a lot of ground, from postwar neighbourhoods inside the Greenbelt to 1960s tract housing at Bells Corners and 1980s subdivisions. Knowing your street's era is the quickest way to guess what's in your walls.
Nepean's housing at a glance
- Postwar (late 1940s–1950s). Early subdivisions near Carling and Merivale. Nearby veterans' housing in Carlington (the "Vets") went up in 1945–47 on former Booth lumberyard land annexed from Nepean (City of Ottawa, Veterans' Housing Character Area (PDF)).
- 1958–1960s. Lynwood Village in Bells Corners, one of Ottawa's first tract-housing developments, built mostly 1958–1966 and now 1,700+ homes (Wikipedia, Lynwood Village). Other 1960s–70s neighbourhoods of bungalows and split-levels followed across the former township.
- 1970s–1980s. Centrepointe, Barrhaven's early growth (see our [Barrhaven page](/guides/plumbing-barrhaven)) and infill.
Common plumbing issues
- Pre-1958 homes. The City says homes possibly affected by lead service pipes are typically those built before 1958 (ottawa.ca, How can I tell if I have a lead service pipe?). Galvanized steel supply lines were also common in that era. They rust from the inside, so watch for low pressure and brown water. Cast-iron drain stacks and clay sewer laterals are also likely.
- 1960s bungalows and split-levels. Copper is now 55–65 years old. Pinhole leaks, seized valves and corroded cast-iron sections are common.
- Late 1970s to mid-1990s renovations or builds. Check for poly-B (Square One, Poly-B plumbing).
- Basements. Older homes often have a floor drain but no backwater valve. The City's Residential Protective Plumbing program offers rebates for new ones.
- Water. Ottawa's central water supply is very soft, about 30 mg/L total hardness according to the City (ottawa.ca, Drinking water quality FAQ), so heavy scale is not usually the culprit on city water. White crust on a tap is more often a slow drip drying out. Homes on private or village wells are a different story.
Winter tips
Bungalows with crawlspaces or uninsulated rim joists can freeze at the point where the water service enters. The City of Ottawa recommends keeping areas with water pipes above 8°C, insulating exposed pipes, sealing cold-air leaks and disconnecting outdoor hoses before winter (ottawa.ca, Frozen water service pipes).
When to call a plumber
- Low pressure or rusty water (possible galvanized pipe)
- You think you have a lead service; the City has an address lookup and replacement programs
- A floor drain that backs up or smells
- Seized or dripping shut-off valves ([guide](/guides/shut-off-valve-replacement-ottawa))
- Planning a basement renovation (a good time to replace old drains and add a backwater valve)

Every home is a little different, so we don't post one-size-fits-all prices. Send us:
- A wide photo of the problem area
- Close-ups of the pipe, fixture or label involved
- A short note on what you've noticed and when it started
A licensed plumber reviews every request and replies with a personal quote. No automatic estimates and no obligation. This is a small pilot, so we can't promise a response time, and the form is not for emergencies. If water is actively leaking, close your main shut-off valve first.
