Can a main drain from one tank share drain with emergency of another into sump?

[Keenan]

As title reads, I'm looking to plumb in a frag tank into my main displays sump. I have a bean animal drain system on the main display that uses all 3 drain bulkheads on the sump. I was wondering if I could use a T fitting on both of the mains two emergency drains so that the frag tanks main drain will drain through one of them and the emergency through the other. This would leave the main displays main drain untouched.

I couldn't find anything online regarding this, so I'm guessing it won't work, but thought I'd ask anyways. Thanks

The problem I foresee is that the main drains will draw air into the lines through emergency and may create a lot of air bubbles and noise in your sump. I would probably try combining the secondary overflows and emergencies into one line rather than combine the main drains with overflows if you cannot create additional openings in your sump.

So here is a rudimentary draw up of what I was thinking

Is the below what you're proposing instead?

or maybe this?

I think this may be what you're talking about and would work best

I wouldn't. Keeping lines independent and the dry emergency dry are part of what makes beananimal as reliable as it is.

Agreed, do you have an alternative idea by chance?

This is the arrangement I would suggest if you have to use those three inlets. I would suggest that the emergencies (and even the secondary overflows) do not have to go through any socks and can just open end into the sump at some convenient location

Thanks, I agree this seems like the best of the possible options.

After thinking about this further, you could probably tie the two main drains together, and then the two secondary overflows on a second inlet and the emergencies together on the third inlet. Not sure about the main drain flows and sizes but that would probably be the best arrangement if the common part of the main drain line is large enough to handle both flows.

So the main display is a bean animal but the frag tank will be just a herbie dfrain style. I think I like the approach of alotting a solo spot for each main drain and then tie in all of the secondary/emergency to the same, because it making extra noise from combining them all will actually be a good thing because it will let me know something isn't right.

Ended up going with this and it’s been running two months with no issues, just incase others were wondering. Blue pipe is for the frag tank and purple is display.

Use the last configuration you posted. Each main gets it own dedicated drain. Run both secondary to the last drain, don’t T or Y together though. The emergency drains set well above the sump water level in a different chamber (skimmer chamber). This way if the overflow is using the E-drain, you will hear the problem and fix it. That would be a safe quiete set-up.

As you can see by the pictures, I already have it built out. It’s been working great. Appreciate the advice
