How to muffle the sound of rushing water through main pipe in basement.
I have 2 columns in basement that have recently been redone. I had no idea there was a main pipe there until once they had recovered the column back and I could hear the water rush down. I was told it's because they made that post/column smaller in width. I don't believe that this could cause the pipe to sound as if there is nothing surrounding it.
My question is if there is any type of insulation or something else, that can stop the sounds of rushing water from being heard?
