What is likely happening
Water pooling at the base, weeping valves, or rust on the vessel and piping signals seal or fitting failure, or corrosion of the pressure vessel itself. Corrosion on a pressure-retaining part is a safety matter.
What you can safely check
- Photograph where the water or rust is, so the inspector can see how it progressed.
- Check whether the boiler is adding make-up water constantly (a water meter on the fill line helps).
- Keep the area dry and clear so the source can be traced.
What an inspector will look at
- Shell, tubes and sections for corrosion or cracking
- Gaskets, fittings and valves
- Make-up water rate and water treatment
- Condensate and flue for corrosion
Does this affect compliance?
Corrosion or leakage on a boiler is usually recorded as a defect at inspection and may have to be corrected before the certificate is renewed.
When it becomes urgent
Urgent if leakage is increasing, comes from the vessel itself, or is near electrical equipment.
