- Turn off the boiler at its wall switch or breaker.
- Place towels or a bucket to contain the leak.
- If you smell gas: leave — call FortisBC 1-800-663-9911 from outside.
- Call CANRO at (604) 359-1081 for same-day dispatch.
- Take photos of the leak source and any visible damage — speeds up diagnostic.
Common boiler leak locations we diagnose and repair
| Leak location | Likely cause | Typical repair |
|---|---|---|
| Heat exchanger (HE) | Corrosion, scale erosion, thermal stress crack | $1,400–$3,800 (or warranty) |
| Pressure relief valve (T&P) | Pressure overshoot, faulty valve | $185–$320 |
| Circulator pump seal | Worn seal, bearing failure | $350–$650 |
| Expansion tank | Bladder rupture, fitting corrosion | $220–$420 |
| Boiler fittings / unions | Thread wear, gasket fatigue, vibration | $185–$420 |
| Condensate trap / drain | Cracked plastic, blocked outlet | $185–$320 |
| Auto air vent | Stuck valve, debris | $145–$240 |
| Domestic hot-water plate (combi) | Scale damage, pinhole leak | $420–$850 |
Common causes of boiler leaks in Metro Vancouver
- Over-pressurization. Expansion-tank failure or fill-valve fault drives system pressure above 30 psi — pressure-relief valve discharges water.
- Corrosion from oxygenated water. Old systems with frequent water top-ups introduce dissolved O₂ that pits steel and copper.
- Scale buildup on heat exchanger. Hard water (some Surrey and Richmond areas) leaves mineral deposits that crack the HE under thermal stress.
- Vibration fatigue on fittings. Decades of pump cycling loosen unions and threaded joints.
- Frozen pipework in unheated spaces. Rare in Vancouver but a real risk for crawlspace runs during cold snaps.
- End-of-life heat exchanger. 15+ years of thermal cycling eventually opens micro-cracks.
- Improper installation. Wrong gas pressure, oversized boiler short-cycling, or missing isolation valves all shorten component life.
How CANRO diagnoses a boiler leak
- Shut-off & safety verification. Water supply isolated. Power confirmed off where required.
- Visual inspection of the boiler cabinet, fittings, and surrounding plumbing.
- Pressure-test isolation. Each loop (heating vs DHW vs primary) isolated to localize the leak.
- Heat exchanger pressure test for hairline cracks (combustion-side leaks).
- Combustion analysis on gas appliances to verify no flue-side condensate damage.
- Written quote with three options when repair vs replace is on the table.
- Repair completed with OEM parts where required.
- 1-year labour warranty issued.
Repair vs replace — the 50% rule
| Scenario | CANRO recommendation |
|---|---|
| Leak from fitting on boiler <6 years old | Repair |
| T&P valve discharging on any boiler | Repair valve, investigate pressure |
| Circulator pump seal leak on boiler <12 years | Repair (replace pump) |
| Heat-exchanger crack on boiler in warranty | Warranty replacement of HE |
| Heat-exchanger crack on boiler 12+ years out of warranty | Replace boiler |
| Multiple small leaks on 15+ year boiler | Replace |
| Repair cost > 50% of replacement cost | Replace |

A: Yes — water leaks can cause structural damage in hours and signal pressure or heat-exchanger failure. Shut off water and call CANRO same-day.
