Emergency plumbing in Le Plateau-Mont-Royal

The Plateau means the triplex with the outside staircase and the low basement, most of them built between 1900 and 1930. The main shut-off is often tucked into a narrow basement corner, sometimes shared by all three units, which makes it hard to reach when the ground-floor tenant isn't home. A lot of the drain stacks are still original cast iron, with laneway tree roots and decades of internal corrosion narrowing what's left of the pipe.

Access is the real challenge here: narrow lanes, hard street parking, and spiral staircases that limit what can go down to the basement. A backup in a Plateau triplex usually hits all three units at once, which adds coordinating with the other tenants or the landlord on top of the emergency itself.
