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

Minor weeping leaks at fittings, Persistent condensation on cold surfaces, Inadequate insulation, Flue gas condensation leaking onto shell

Safety: Inspect when boiler is cool to avoid burns.

Locate source: Trace rust streaks back to their origin—check fittings, flanges, and inspection plugs.
Repair leaks: Tighten or re-gasket leaking joints. Replace corroded fittings.
Improve insulation: Insulate cold surfaces to reduce condensation.
Check flue condensate: Ensure condensate from flue or economizer is properly drained and not dripping onto the boiler shell.

Severe corrosion may compromise boiler integrity and should be assessed by a boiler inspector.
