What is a common indicator of water quality issues in a boiler?

A common indicator of water quality issues in a boiler is indeed sudden changes in water chemistry or color. This can signal the presence of contaminants, corrosion products, or altered chemical balances that can adversely affect the boiler's efficiency and safety. Changes in water chemistry, such as fluctuations in pH, conductivity, or the presence of dissolved solids, can lead to scaling, corrosion, and ultimately failure of boiler components if not addressed promptly.

Color changes in the water can suggest the presence of rust or sediment that can obstruct flow and negatively impact heat transfer. Monitoring for these changes is crucial for maintaining optimal boiler operation and preventing costly repairs or downtime.
