Help! Loud overflow.

Help! I had my LFS guy plumb my 100 Int Nuvo. Everything is working great accept for the over flow to extremely loud! How can I remedy this?!

Add a gate valve to the main.

As @blaxsun said you need a way to control the siphon on the main drain.

I agree with @blaxsun . You likely have a lot of air being mixed in the drain line which is what causes the noise. Add a gate valve directly below the union that's already on your main drain line. The gate valve will allow you to fine-tune the drain line to align with the amount of water you are pumping back up to the display so the drain is full of water and no air.

It looks like the 2 drains terminate above the water line in the sump? You want those just under the water surface.
