nano DIY overflow

[MoshJosh]

Want a hang on overflow for a project I'm working on, unfortunately commercial overflows are still a little to big. I figure I will make one out of PVC. . . but I have some questions. First where to source all black pipe and fittings. also what are maximum flow rates for something like 1/2" and 1/4" inner diameter pipe and tubing? I wont be putting a ton of flow through this and want to keep as small as possible.

My idea is a hybrid of theses 2 videos I found (disclaimer: I did not make these videos, nor am I affiliated with their creators.):



first cut any "excess" off the elbows and caps of the PVC



Then assemble this piece and cement it together



next cut the top off said piece to limit it's height



then use a piece of flexible hosing or bent PVC to form the "syphon" portion of the overflow.





then cut or drill my desired overflow height. . .

it will eventually get covered in gunk and life and coraline anyway.
… ive seen these DIY overflows on ebay ect… you don't want to drill?
I like bulkheads and overflow boxes, wiers to overflows. ect.
