The fill was too fast, also. The dump adjusters (one on each of the 4 dump valves) also worked as a muffler that my neighbors appreciated.
I had 2 feed lines, so I only needed 2 fill adjusters.

<edit> It was nice to dial in the speed I wanted, but at 1/2" it was all up or all down with the hit of a button. I swear it jumped 4" off the ground the first time I hit the all up switch after install.
