How would I do that? Someone said that I cannot make both overflows a Herbie and one would be a Durso. I was just looking at that thing, and for some reason my returns are plumbed with a bulkhead as in as in I don’t know who, but there is a hole in my overflow outside where the fish go is not the piping. this home was plugged with a bulkhead and my return lines were connected there. This does seem to throw a wrench into the plans. I can easily figure out a way to do my returns, but that bulkhead where my returns are is very concerning and odd.
