Burnham Boiler: Leaking water
Water around a Burnham boiler can be a discharging pressure-relief valve (overpressure), a blocked or split condensate line, or a failing seal, fitting or heat exchanger. Water on live electrics or a hot heat exchanger is a safety issue.
Water around a Burnham boiler can be a discharging pressure-relief valve (overpressure), a blocked or split condensate line, or a failing seal, fitting or heat exchanger. Water on live electrics or a hot heat exchanger is a safety issue. On Burnham boilers, this is linked to 2 fault codes (Low Water Pressure, Condensate Fault). Below are the likely causes, the safe checks you can make, and exactly what our licensed BC gas technicians do — because boiler repair in British Columbia is licensed gas work, not a DIY job.
Boiler repair is licensed gas work in BC. The checks below are the safe limit of DIY. Do not open the boiler or work on gas, combustion or safety controls — read the fault code, reset at most once, and call a licensed technician if it returns.
What you might notice
- Pressure gauge reading low (or very high)
- No heat; boiler will not fire
- Needing to top up system pressure often
- Lockout, often after very cold weather
- Water pooling near the boiler
- Gurgling sounds from the trap
Safe checks you can make first
These are the only steps a homeowner should take. If they don’t resolve it, stop — the rest is licensed gas work.
- 1Identify where the water comes from — top, bottom, condensate pipe, or a fitting
- 2Check pressure: above ~30 psi suggests an expansion-tank / PRV fault
- 3Place a container to catch water and protect the floor
- 4Always call — do not run a leaking boiler near electrical components
