The emergency drains should be ok if they are joined in to one before they hit the sump though eh?

the other option you have is a stockman.all my tanks have stockmans and they are all silent

Yes if you have two or more emergencies, they can be tied together. Same if you have two or more primary drains, they can also be tied together in fact it's best if the primary drains all connect into one gate valve. You just can't connect the primary & emergency/back up drains together simply because you'll get an echo noise up the emergency drains which can be pretty noisy.

My herbie is mostly silent.

I just changed to a DC return pump and Herbie, so now the remaining noise is from the Skimmer and the MP40's. Not much else I can do to quieten it down.

I try not to have a slight trickle. I can usually keep it just below the top of the emergency. Although it does fluctuate as my sock filter gets dirty.

Yea all my equipment is in my basement so I dont hear anything other than my MP40s. I'll be running 4 of the MP40s on my new build, so i'd imagine it's going to drown out any other sounds. I've decided to go with the herbys and run 4 drains and only teeing together the emergency drains.
Thanks to all for the input and keep it coming

Just to note, if your new tank has two separate overflows you'll need to tee the primary drains into a single gate valve for control. While the overall water flow rate will be constant the flow rate to each overflow will vary, especially with any kind of wave, so if you use two separate gate valves you will be constantly fighting to tune them properly.

It'll be a coast to coast internal overflow.

Herbie now but when I first setup up tank was using dual Dursos with basement sump. Worked perfect for about 5 years before I changed. Would say Herbie is slight more maintenance as every few months I need to open gate valve to clear snails, something never had to do with Dursos.

Only reason I changed was I had a long horizontal run under room used as a office and could hear gurgling in lines when house was quiet (running 1000gph). Herbie did stop the noise heard in the room.

Unless you feel like playing, would say just keep Dursos, as I found really no difference in sound at display or sump (both were/are silent).

I run a Durso....but I dont have a choice as I have 1 return and 1 over flow. I dont think I would change anyways.
