How to quite return lines into sump?

[puccie1]

Does anyone have any ideas how I can quite down my return lines into my sump? It is so loud any ideas be appreciated .

Place them deeper into the sump, ie: underwater.

Mine is horrifically loud. Mine is due to a frankly rubbish return design that yours doesn’t seem to have. That said d the best thing I found was a silencer bought off of eBay for £4. Looks like a corkscrew and slows the return flow.

What type of drain do you have?

As said above make sure they are exiting under water.
