What is a common sign of a boiler leak?

A drop in water level and visible water around the boiler base is indeed a common sign of a boiler leak. When there is a leak, the water that is supposed to remain in the boiler will escape, leading to a decrease in the water level. This drop can be observed on the water gauge. Additionally, the presence of water pooling around the base of the boiler is a clear indicator that water is escaping, highlighting the issue.

Understanding this symptom is crucial for boiler safety and efficiency. If left unaddressed, a leak can lead to more severe problems, including equipment damage and potential safety hazards. Regular monitoring of the boiler's water levels and conditions around its base is essential to detect leaks early and take corrective action before they escalate.
