You might be exceeding the design flow rate with a pump that moves water too fast. If the pump has to move water too fast, it might be because of incorrect pipe design where larger pipe and valve ports are needed. Otherwise, you can use another brand. However, if the flow rate is too high through the pipes, it can wear them to cause leaks in the future.
