Plumbing Inspection in Montréal

Plumbing problems are among the most common findings in Montréal houses, condos and plexes, and some of the most expensive to ignore. I'm Pantelis Ambatzis, a Certified Master Inspector (CMI®). As part of every inspection, I check the plumbing that is visible and accessible and explain what I find, in English or French.

What I check

• Water entry and main shut-off valve: where they are, their condition, and whether the valve is accessible;
• Supply pipes: the type of material (copper, galvanized steel, plastic), its approximate age and condition, leaks and corrosion;
• Drains and vents: cast iron, ABS or other materials, slope, leaks, slow drains, and the floor drain in the basement;
• Backwater valves: whether they are present on basement fixtures and accessible for cleaning;
• Fixtures: sinks, toilets, showers and tubs, run to check flow and drainage;
• Water heater: type, age, relief valve and its discharge pipe, signs of leaks;
• Private well and septic system, where applicable: I note what is visible and recommend a specialist for testing.

What I often find

In older Montréal houses and plexes, I often see a mix of materials: original galvanized or cast-iron pipes connected to newer copper or plastic. Where two different metals touch without the right fitting, corrosion speeds up; this is called a galvanic reaction. Other common findings are slow or leaking drains under sinks, water heaters near the end of their life, missing or buried backwater valves, and signs of past leaks under bathrooms. Some insurers ask about certain pipe materials and the age of the water heater, so the report notes both when they're visible.

Limits of the inspection

The inspection is visual and non-invasive. I don't open walls, I don't run a camera through the sewer line, and I can't see pipes hidden in walls, floors or underground. When something needs a closer look, I recommend the right specialist: a licensed plumber, or a sewer camera inspection for the main drain. When I see signs of water damage, we can go further with a moisture intrusion inspection, the thermal camera or a mold inspection.

The report

Plumbing is part of every pre-purchase inspection. You receive a written BNQ 3009-500 report with photos, findings ranked by priority and maintenance advice, often delivered the same day. Rates are on the price list.
