Yours is working better than mine then! My only complaint would be the ball valves. It seems like I can never get the flow "perfect". Typically, I get it dialed in and running quietly, but there is always a slight difference between my return rate and the overflow drain rate, and over the course of time (days, sometimes weeks) I always have to fine tune it again which takes me anywhere from 15-30 minutes.
@exnisstech - I would recommend replacing the valves before filling if you are already feeling inclined to do so. It's not the end of the world, but I do wish I could make smaller adjustments to flow more easily.
