Noise in the system - The water flow rate is too high

What does System noise (high flow) mean?

Audible noise in the system pipes is caused by excessive water flow, which can lead to turbulence, cavitation, or pipe vibrations.

• Pump operating at too high a speed or output than required for the system.
• System design not matched to the current flow rate.
• Partially closed valves creating high velocity flow.

Click steps to track your progress.

1. 1

   Access the Grundfos GO Remote app and review the pump's current operating mode and settings.

2. 2

   Reduce the pump's suction head or adjust its control mode to a lower setting to decrease the flow rate.

3. 3

   If the pump has multiple settings, try a lower speed or a different control mode appropriate for your heating application.

4. 4

   Ensure that system valves are not partially closed causing flow restrictions at high speeds.
