I got cavitation whenever I ran the pump and had the same issue on 3 different systems. When you have cavitation, you will know it. It is a gurgling, growling, water pump sucking air, labouring sound. Very unmistakeable when it happens.

Same kind of sound one would get from a swimming pool pump cavitating I guess?
