Quick Answer

A pressure relief valve that drips (often from an outside discharge pipe) is usually doing its job because pressure is too high — typically a failed expansion tank — or its seat is worn. BoilerPart.ca diagnoses the real cause across Greater Vancouver, never just capping the valve.

A weeping relief valve is a symptom, not the disease. It’s usually responding to high pressure (a failed expansion tank) or has a worn seat — both repairable.

What you’re noticing

Water dripping from the outside discharge pipe
Relief valve weeping or hissing
Pressure climbing when heating
Intermittent discharge

Common causes

  • Failed expansion tank raising pressure
  • Overfilling fill valve
  • Worn relief-valve seat (debris)
  • Genuine over-pressure

What you can safely check first

Beyond these safe checks, do not open the boiler or touch gas, electrical or sealed components — BC law requires a licensed gas fitter. Call us for a proper diagnosis.

Note when it drips (heating up vs constant)
Check pressure cold vs hot
Look for the outside discharge point
Never plug or cap the discharge pipe

When this is urgent

Not an emergency, but persistent discharge wastes water and signals a fault.
