It’s one thing to have equipment found to be in violation of code. It’s another thing to have an expensive and possibly fatal accident as a result of such operation. Avoid both of those things by noting the common mistakes regarding cutoffs and flow-sensing devices, and by engaging your inspector to make sure you are up on the latest mix of requirements for your jurisdiction and particular system.
Each year, The National Board of Boiler and Pressure Vessel Inspectors issues an annual Report of Violation Findings that identifies specific violations commonly found on five types of pressure equipment during jurisdiction-required inspections: high-pressure/high-temperature boilers; hot water heating/supply boilers; low-pressure steam boilers; potable water heaters; and pressure vessels.
