This gives me the ability to run on low most of the time because it is cheaper and on high when I want a lot of water. On high I also can adjust the valve to get exactly the amount of water I want. Just some random thoughts.

Also did I miss the autofill? I would always do an autofill.
I am getting a 3 ton waterfall with about 1.5-2 tons of border rock that will have some weeping water. I will ask about how they valve it. As far as the autofill a lot of the builders do not want to do them because of problems. Have people here seen a lot of problems with autofills?
