Noisy sump! Going insane! Help!!!

Two things that worked for me:

i) make sure you have the right amount of holes in the cap of the Stockman Standpipe (right 'breathing')

ii) if your overflow piping runs straight down into your sump reduce the piping size, make a horizontal U with the reduced size pipe, submerge the reduced overflow pipe under the water level, and add a 45 elbow at the very bottom
