Every valve in this plant room is numbered and tagged, and it's not just for show.
Each number matches a chart on the wall telling you exactly what that valve does, hot water isolation, a specific circuit, whatever it is.
Anyone servicing this system later, whether that's us in a year's time or a different engineer entirely, can see straight away what they're dealing with.
It's a small thing, but it's a big part of what makes a plant room properly maintainable and compliant.
