Dundarave's waterfront setting means salt air is a real factor in how gas lines age here, alongside a mix of older homes and larger rebuilds.

Quick answer
In Dundarave, gas line installation and repair for a furnace, boiler, tankless unit or water heater has to account for the neighbourhood's waterfront location, where salt air accelerates corrosion on exposed exterior piping more than it would inland. A District of West Vancouver gas permit, pressure test and inspection apply before startup. CANRO's licensed gas fitters check exposed sections carefully before recommending a repair or a full line replacement.

Dundarave is a waterfront village neighbourhood, with houses along and near the seawall that face regular exposure to salt-laden air off the water. That exposure matters for gas line work in a way it doesn't in an inland neighbourhood, since any exposed metal fittings or exterior-run sections corrode meaningfully faster here than the same materials would a few kilometres up the hill.
The neighbourhood's housing stock ranges from older character homes to larger custom rebuilds, and regardless of a house's age, exposed exterior connections near the water get a closer look during any assessment than they would on a property set back from the shoreline.
A sulphur smell near the meter or anywhere along a line, exterior or interior, is the sign to leave the property immediately.
Sizing a Dundarave line follows the same load calculation as anywhere else: totalling the BTU input of every connected appliance and measuring the actual run. What's different here is the material and coating choices for any section exposed to outside air, since standard black iron left unprotected near the water corrodes faster than it would inland.
Where a homeowner is adding a new appliance, like a tankless unit relocated to an exterior wall for space reasons, CANRO factors in that exterior exposure when recommending materials and protective coatings, not just the load calculation itself.
A gas permit from the District of West Vancouver applies to new lines and most modifications, with a pressure test and inspection before an appliance is connected. Properties close to the waterfront sometimes involve additional coordination given the shoreline's proximity to the work area.
| Step | What happens | Handled by |
|---|---|---|
| Assessment | Exposure, corrosion risk and load reviewed | CANRO gas fitter |
| Permit | Filed with the District of West Vancouver | CANRO office |
| Installation | Line run or repaired with corrosion protection | CANRO gas fitter |
| Inspection | District sign-off before startup | District of West Vancouver |
A single corroded exterior fitting can often be replaced on its own without touching the interior portion of the line, provided the rest of the run is still in sound condition.
Where exterior exposure has affected more than one section over the years, CANRO recommends a planned replacement of the exposed portion rather than a series of repeated repairs on fittings that will keep failing under the same salt air conditions.
The visit starts with the meter shut off and a close look at any exterior-exposed sections of the line, since that's typically where a waterfront property's gas line shows its age first.
CANRO's technicians hold a Technical Safety BC gas licence, so the finished work meets the standard a District of West Vancouver inspector checks for, with materials chosen specifically for the property's proximity to salt water.
Safety note
Gas line installation, repair and pressure testing must be performed by a Technical Safety BC licensed gas fitter, since a corroded or leaking line near salt water is a genuine safety hazard. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you smell gas near a line or appliance, leave the home immediately and call FortisBC at 1-800-663-9911 from a safe distance.
Yes, exposed exterior metal fittings corrode noticeably faster near the water than they would on an inland property.
CANRO recommends materials and protective coatings suited to salt air exposure for any exterior-run section near the waterfront.
Yes, permit requirements apply regardless of the property's proximity to the shoreline.
A visual check during any service call is worthwhile, since corrosion here progresses faster than an inland property would experience.
Usually yes, if the corrosion is isolated to that fitting and the rest of the run remains sound.
