Hi, I need some advice on getting the hum from the hot tub motor (which is new) to be a little less loud. The motor frame is sitting on four small pieces of rubber car heater hoses which are helping with noise reduction but when inside the house you can hear a hum like a loud fridge/freezer.
Here is a pic of the motor (don't pay attention to what it is sitting on, the pic was taken before everything was set up)
