A leaking boiler is one of the most common — and most urgent — heating calls in Metro Vancouver. Because a boiler is a sealed, pressurized water system, even a small drip can drop system pressure, leave you with no heat, and cause water damage if it is ignored. CANRO Heating & Cooling has repaired boiler water leaks across the Lower Mainland since 1999. Call (604) 359-1081 for same-day help.

Is it a water leak or a gas leak?

This page is about water leaks — dripping, puddling, or steadily dropping boiler pressure. That is different from a gas leak. If you ever smell gas, leave the home and call from outside; a water leak, while not explosive, still needs prompt repair to prevent damage and protect the boiler.

Why your boiler is leaking water

Most boiler water leaks trace back to one of these causes:

  • Pressure relief (T&P) valve discharging. When system pressure climbs too high — often a failed or waterlogged expansion tank — the relief valve opens and releases water as a safety measure.
  • Corroded pipe joints & fittings. Years of heating and cooling cycles loosen unions and corrode threaded joints, which begin to weep.
  • Circulator (pump) seal failure. A worn circulator pump leaks from the shaft seal or flange gaskets.
  • Auto air vent or fill valve. Automatic air vents and the pressure-reducing fill valve are common, easily-replaced leak points.
  • Waterlogged expansion tank. A failed expansion tank cannot absorb expansion, spiking pressure and forcing the relief valve to leak.
  • Heat exchanger corrosion. On condensing combi boilers, internal corrosion or a cracked heat exchanger is a serious water leak that needs professional assessment.

Is a leaking boiler an emergency?

A boiler that is leaking fast, losing pressure, and producing no heat needs urgent attention — especially in winter. Dropping pressure with a running boiler can damage the unit, and water near electrical controls is a hazard. We offer same-day response across Metro Vancouver.

What to do right now

  1. Switch the boiler off and let it cool.
  2. Close the water feed (filling loop) and, if you can, isolate the leaking section with its service valves.
  3. Put a container under the drip and note the pressure-gauge reading.
  4. Avoid repeatedly re-pressurizing a leaking system — call for service.

How CANRO repairs boiler water leaks

We pressure-test the system, check the expansion-tank charge and relief valve, inspect the circulator, fittings, air vents and fill valve, and on combi units evaluate the heat exchanger. We repair the source, re-pressurize correctly, bleed air, and confirm a clean heating cycle before we leave.

Boiler leak repair cost in Metro Vancouver

Relief valves, air vents and fill valves are typically $150–$400. A circulator pump runs about $400–$800, and an expansion tank $250–$500. A failed heat exchanger is major — we give you honest repair-vs-replace numbers and upfront pricing.

Frequently asked questions

Why does my boiler keep losing pressure?

A persistent pressure drop usually means an active leak (a fitting, the relief valve, or the expansion tank) or a waterlogged expansion tank — it should be diagnosed, not just topped up.

Is a leaking boiler an emergency?

If it is leaking quickly, losing pressure, or leaving you with no heat in winter, yes — call for same-day service. Small weeps still need prompt repair before they grow.

Can a leaking boiler be repaired or does it need replacing?

Most leaks — valves, vents, pumps, fittings — are straightforward repairs. Only a corroded or cracked heat exchanger usually pushes toward replacement, and we tell you honestly.

How fast can you come?

We offer same-day response for boiler leaks across Metro Vancouver.

Frequently asked questions

How often should a boiler be serviced?
Annual servicing is recommended for all residential boilers. CANRO's annual service includes combustion analysis, heat exchanger inspection, expansion tank pressure check, condensate trap cleaning, and a full safety check. Annual maintenance is also required to keep most manufacturer warranties valid.
How much does a new boiler cost in Vancouver?
A typical residential high-efficiency gas boiler in Metro Vancouver costs $7,500–$15,000 installed, depending on size, brand, and whether the system is heating only or a combi unit that also handles hot water. CANRO provides a free written quote with three options at different price points.
How long does a boiler last?
A well-maintained cast-iron boiler can last 25–30 years, a modern high-efficiency condensing boiler typically lasts 15–20 years, and a combi boiler 12–18 years. Annual servicing has the single biggest impact on lifespan.
My boiler is making a banging or kettling noise. Is that dangerous?
Kettling (a banging or whistling sound) is usually caused by limescale build-up on the heat exchanger and is a sign the system is overheating in localised spots. It will not always cause immediate failure but it shortens the life of the boiler and should be addressed within a few weeks.
Do you service Viessmann, IBC, Baxi, Laars, and Weil-McLain boilers?
Yes. CANRO is one of the few HVAC companies in the Lower Mainland with deep experience on European and high-end North American boilers including Viessmann, IBC, Baxi, Laars, Weil-McLain, NTI, Navien and Rinnai. We carry common parts in the truck.
Should I repair or replace my old boiler?
A useful rule: if the boiler is more than 15 years old and the repair cost is more than 50% of replacement, replacement is the better investment. CANRO will give you both a repair quote and a replacement quote and let you decide.
What HVAC services does CANRO offer in Metro Vancouver?
CANRO installs, services and repairs boilers, furnaces, heat pumps, hot water tanks, tankless water heaters, gas fireplaces and air conditioning across Metro Vancouver. We work on residential homes, townhouses and condos throughout the Lower Mainland.
How long has CANRO been in business?
CANRO has been serving the Greater Vancouver area since 1999. Our founder George is recognised by customers as one of the most experienced boiler and hydronic heating technicians in the Lower Mainland.
