Makeup water refers to the fresh water that needs to be added to heating, cooling, or boiler systems to replace water that's been lost through evaporation, leaks, or routine maintenance. It's like topping up a car's radiator when the coolant level gets low. Building maintenance professionals need to understand makeup water systems because proper water levels are essential for these systems to work efficiently and safely. This term often appears in job descriptions for boiler operators, HVAC technicians, and building maintenance engineers.
