Overflow Drain Muffler

thingiverse

I recently drilled my bio cube 29 and installed an overflow box with a 1" drain line to alleviate the excessive noise generated by the drain flowing into the filter sock. This issue had become so pronounced that I could clearly hear it on every floor of the house, prompting me to seek out a solution. By implementing this fix, I have successfully reduced the noise level going into my sump by at least 75%, creating a significantly more peaceful environment within my home.
