mine has a 1" bulkhead with a 1" piece of pvc stuck in it.. about 2" up there are 2 3/4" elbows trimed down and siliconed in place (this was a pain in the butt and took several tries)
the main pipe extends above the tank so i can grab it .. its capped with painters tape with a small hole poked in it so keep the syphon broken
ive added a second U pipe from the tank to the overflow.. so now theres the original 1" and a second 1.5" U as well...
the box is rated for 800gph (eshopps pf800).... i have no idea how you could get this thing to flow that much... with no mods straight out of the box the max i could get it to flow was maybe 300gph IF that much
Upload a pic of it if you can, I'd like to do something like that on my 1200gph overflow. I had to trim the edge of my 90 degree fitting on my CPR durso since I replaced the stock bulkhead fitting with a couple of adapters. Ditching the standard bulkhead fitting actually increased the flow.
