Put it this way, I can hear it on the second floor of my house. The pump has 1 1/2" ins & outs but I had to reduce them down to 1" & the only way to change it is to empty the tank & that won't happen for a month or 2 yet.

I started with a 1200 GPH pump then switched to a Dart (2400) but wanted more flow hence HAMMERhead

I have some sound dampening pads so I think I will see if I can get one under it & cut a thick piece of foam or sound proof padding to go under the plywood but can't do that until ATO tank is empty.
