Possible Causes

Incorrect flue slope, Failed flue joint seals, Condensate not draining back to boiler, Cracked flue components

How to Fix / Troubleshooting

Safety: Flue gases are hazardous. Do not dismantle flue components yourself.

  • Observe drip location: If water drips from flue joints or wall penetration, note the exact area.
  • Check condensate pipe: Ensure the condensate drain from the boiler is not blocked or frozen.
  • Do not seal over flue joints: Avoid using silicone or tape on flue joints; this can trap condensate and flue gases.
  • Technician tasks: A heating engineer must inspect the flue system, correct the slope, replace damaged seals or sections, and ensure safe operation.
