Common boiler water leaks in Surrey homes

Whether your system is an older gas boiler or a modern condensing combi, the usual leak sources are the same:

• 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 your leaking boiler an emergency?

A boiler leaking fast, losing pressure, or leaving you with no heat is urgent in Surrey’s climate — and water near the controls is a hazard. We respond same-day. (A water leak is not a gas leak; if you smell gas, leave and call from outside.)

What to do until we arrive

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 leaks in Surrey

Our technicians pressure-test your system, check the expansion tank and relief valve, inspect the circulator, fittings, air vents and fill valve, and evaluate the heat exchanger on combi units — then repair the source, re-pressurize and confirm a clean heat cycle. We serve South Surrey, Newton, Fleetwood and Guildford and the rest of Surrey.

Boiler leak repair cost

Valves and vents are typically $150–$400, a circulator pump about $400–$800, and an expansion tank $250–$500 — always quoted upfront.
