The only reason I want to keep it in the box is to keep the resale value of the tank high. And there's a 3D background to deal with.
Plumbing EXPERTS! Overflow question.

1) How much flow will this design handle in the sizes mentioned here?
2) Does the valve have to be a gate? What happens if ball valves are used instead?
I'm about to make my first venture away from my niagra falls style overflows that sounds similar to a boat right in my living room, and I'm in the same boat, single dinky overflow box and a Dart. Have a 2" and a 1.5" hole in the overflow box, and can hack into the back side of the box.
Thanks for any advice, and am not trying to derail this thread, but I know guys are the ones to ask......

1) Two inch main drain so around the 2500 gph max. I'm shooting for 10x turnover in a 225 so 2250 gph roughly (without taking in other factors).
2) You basically need a gate valve for a herbie because of the fine adjustments needed that a ball valve won't give you.
So you're using an overflow box as opposed to an overflow tower? Have you checked out the beananimal?

It's a standard tower. Bulkhead fittings run through the bottom of the tank. Overflow is in the back corner of the tank so I can put holes in the back or side of the tank. I tried for 2 2" drains but could only fit a 2 and 1.5.
What I have now is the Y type T (sanitary T?) on the 2" drain, cap witha small hole drilled in it.
Never tried any kind of truley silent overflow, and definetly nothing with the valve on the end. Not sure where I'd get gate valves around here without ordering them, is there any other alternative?
Any links to these things?

If you have two bottom bulkheads you can run a standard herbie. This is a modified herbie because I have no space for that. Just google herbie overflow.
Not really. Gate valves are the only way to fine tune the flow to make it really silent. Ball valves simply won't work for this. Check Amazon. They have good prices on large PVC gate valves.
100% right on fine tuning ball valves J if you don't have a large enough sump to handle error gate valves are the way to go for sure ...A little trick for ya on a straight pipe in the overflow to make it all the more quiet is cap it drill about five 3/16 th holes like you would a durso and take a chop saw cut a block for a guide so you don't cut to deep at one inch increments bring the saw blade down halfway through on both sideswill give you plenty of flow!!!!
