Remeha Condensate leakage from flue or trap

Condensate water dripping from flue joints or outside the condensate pipe

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect flue slope, Loose flue joints, Cracked condensate trap, Blocked condensate outlet

Safety first: Condensate is mildly acidic. Wear gloves and eye protection.

Check flue slope: Ensure the horizontal flue sections slope slightly back towards the furnace so condensate returns to the trap.
Inspect joints: Examine all visible flue joints for signs of water staining. Reseat or replace seals as needed.
Examine condensate trap: Remove and inspect the trap for cracks or poor seals. Replace if damaged.
Clear outlet: Ensure the condensate discharge pipe to the drain is clear and properly supported.
