How to turn down the high pitched sound on a D5 Water Pump

Question

Any tips for those that want the high pitched sound emitting from a D5 Water Pump?  Bitpower software?  Any software?  Seen some comments that D5's can't be adjusted and DDC's can.  Hopeful that's not the case as I really don't want to reinstall a new pump.  Help!!!

Hello Ribs,

Which D5 pump do you have? You can turn down the speed of the pump by the button on the D5 pump.
And would you send us the video to show the problem?
Please send it to follows email address, thank you.
