Re: Vented Loop Design?
...and that's why I removed the duckbill and modified it to match the original design. I can see where the vent tube eventually goes vertical, and it has worked this way since 1987. There is no way that the duckbill could be mounted vertically unless I change a bunch of 3/4" exhaust hose.
I guess that I made the right decision.
