Plumbing/Noise Question

[Reef23]

Hi all,
I will be plumbing my new tank in the next few weeks and had a few questions on noise. My tank has a coast 2 coast overflow with three drains and 2 returns. My sump is located behind the wall that the tank sits against. The drains will be coming out the bottom of the overflow for about 10 inches then a 90 fitting and a 12 inch horizontal run to another 90 and straight down into the skimmer section of the sump. Will this cause any noise plumbed this way ? Any suggestions

3 drains as a Beananimal should be silent

first of all.....welcome to Canreef!.......sounds like your running a BA Herbie....in which case you shouldnt get any noise at all because there is no air in the primary drain and no siphon.....

Thanks guys,
I know the bean animal drain setup should be silent but I was wondering with the water falling 10" to a 90 if that would cause some noise ?

Souldn't cause any issue, just the end of your plumbing is submerged.

If there is no air in the pipe there won't be much noise.

The main drain line should have a gate valve installed directly before the pipe drops into the sump. When you adjust the valve the main line will be full of water so there won't be a cascading effect. It's important that this main line does not tee into the other drain line(s) at any point before or after the gate valve.

Thanks that's the exact info I was looking for. I'm still alittle confused with what I should do with all three drains going to the sump. Main drain will drain directly to skimmer section. Other two use as emergency drains and plumb to what part of my sump ?

The other two drains could be tee'd together into one line if you want and can go into any section of the sump you want since they are for emergency only unless you plan on running some water through them all the time which is an option. For simplicity you could just make all lines go into the same sump section.
