I installed the Korillia pumps and they have an annoying hum.One was much worse than the other so I took that one and placed it in the sump.I can hear it over my fans and the wave box so I know I am not crazy(well I know I am letting myself into that one)I don't know if its because they are new that they hum.Maybe this is normal but one of them was pretty annoying.I will see tonight with the fans off how loud the other one is.The wave box and lights will be shut off so I can hear if its bad or not.Maybe the one pump is loud.Well in my sump who cares.The only thing is I didn't need any more power heads.I have enough sitting in a bin.
