Coast to Coast : Any issues with failures?

[butrflynlambie]

I have been planning for a tank for some time and have a basement in mid build, I have the wall framed to allow for a synergy overflow/coast to coast and was looking at prices from different vendors. In my search I ran into one installer that said the tank I wanted could be made but it would not be warranted by the manufacturer.

His claim was that this type of overflow put undue stress on the back wall of the tank on the backside as the water exited the tank in the overflow box and was a greater potential failure in the structural integrity of the tank itself. He was very adamant about this.

I know one vendor specializes in this type of setup, but am now somewhat concerned that the design of the overflow has a distinct disadvantage due to some inherent design flaw with weight of the overflow pulling the back pane away/outward and thus a failure of the tank.

Can anyone substantiate this as a true concern or debunk this as some paranoia or alternate agenda of the representative to have me buy different product?

There are ways for the manufacturer to add bracing at the inside corners, or eurobracing the top, or using thicker material for the back.

but has there truly been a failure. The installer was adamant that this was a poor design. I thought the bracing itself was for the benefit of tanks that were rimless to begin with.

Thinking of just getting a small cad lights tank in the interim.

I am unaware of failures due to an external overflow, though it doesn't mean there hasn't been.

I do know that if I am ever able to do another tank, it will have a coast to coast overflow.

Since he builds them he would be the one to ask.
He might be busy with MACNA this weekend but I'm sure when he gets a chance he will respond
But to me no I don't beleive this if this was the case would reef savy be using them? I think not but that's just my two cents

I would find another manufacturer if they are telling you that. You're talking about less than 1 gallon of water inside the rear external box. If they have had failures, then it's not due to an external overflow, but how the tank was assembled. It sounds like a lame excuse to not stand behind their own work. I have never seen a tank fail because of an external overflow.

He still hasn't supplied a quote for what I wanted. I literally have my basement wall framed for the overflow to go through the wall into the next room, so I was not so inclined to change the requirements of the tank build even after his instance.

I'll move on and stick with my original plan. Thanks for the comments back. I was very concerned after speaking to him and feel much better about this type of overflow in use.
