Drain is now more adjustable after going with traditional durso drain pipe. I would guess that the valve I had on before was allowing excess air. I can raise and lower overflow levels using the gate valve.
7/64" was the magic number for this one, Greg.
Here is a quick video of the sump. Is this the usual flow or does it look like to much air still? It isn't that loud, just wondering if it looks like it's working properly.
