Answer: What Is Boiler Pump Cavitation and How Is It Fixed?
Cavitation occurs when the circulation pump creates vacuum bubbles in the water that collapse violently, causing a rattling or grinding noise. It is caused by: low system water pressure (below 1 bar), a blocked pump inlet strainer, air in the system, or the pump running too fast for the system conditions. Fix by repressurizing, bleeding air, or adjusting pump speed.
