Most of the other candidates in today's batch are Shorts or hashtag-spammed clip bait. This is the exception — a full-length podcast episode with Cheryl Heiser, a boiler inspector who specializes in internal inspection, failure analysis, and forensic photography of industrial steam systems. That last part is what makes it unusual: documenting what's actually happening inside a boiler (pitting, scale, caustic gouging, oxygen attack, stress-corrosion cracking) is its own discipline, and most water-treatment content skips right past it.

Expect substantive discussion of what an inspector looks for when a tube ruptures or a drum shows distress, how to distinguish waterside versus fireside failure modes, and why proper photographic documentation matters when the failure becomes an insurance claim or a root-cause investigation. The Scaling Up! H2O podcast is aimed squarely at working water-treatment professionals — not laypeople — so the vocabulary is real and the examples are drawn from actual plant work.

If you've ever wondered what the difference is between "the boiler tripped" and the metallurgical story of why it tripped — the chloride concentration mechanism, the deposit that insulated a tube until it overheated, the feedwater chemistry that quietly thinned the metal for months — this is the kind of conversation that fills in those gaps.
