Why would flow through a durso slow down overtime?

Pretty sure it is 2".

Smaller air hole = faster flow in durso...

I've experienced the opposite (running faster+gurgling) and found that crap was building up in the durso air-hole, but it sounds like you're cleaning yours regularly... Are you able to snake out the drain line? I'd guess somethings stuck/built up in the line.

I guess I am going to have to fish a line down it and attach a rag to it to pull through. I don't know what else there is to do.

Thanks everyone for all of the replies.

ill tell you right now that with a durso setup on even 2" drains, your pump WILL outflow the drains. Go to a bean animal setup and youll be all set.
