Hi all, I'm trying to learn as much as I can about the overflow options in preparation for a new setup and I've got some questions I've wanted to ask.
1. Assuming there is an internal overflow weir box, is there any benefit in using an external overflow box for Herbie overflow as opposed to just plumbing 90 degree elbow off the bulkhead (also Herbie)? To my understanding, they both seem to work the same way, with a gate valve attached to the drain pipe placed on the lower side to control the flow and silence the drain. Is there a reason to choose one method over another?
Something like the photo below (the pic has soft plumbing but it can be hard pvc) compared to one of those esshops/fiji cube external overflow boxes with standpipes.
2. The small to medium size esshops/fiji cube external overflow boxes attach to the tank with one large bulkhead to the tank. Are they safe enough with the hole being just one (though large)? Reckon they are worth getting?
3. They don't sell external overflow boxes where I live. I don't know if that's what I want yet but I'm thinking it looks straightforward enough to diy with some acrylic and bulkheads. The thing is part of me is pretty scared since any failure would mean disaster. Especially worried about the bulkhead to the external box connection. Would you think it easy to do?
Cheers
