Ampmaster 3000 question

[goodguy1977]

I am looking into buying one of these for my return. I have a 120 reef ready. The pump will replace another pump. The sump is in the basement and water will travel up about 8 feet. There will be a T because I have two returns, one on each corner of the tank. There is 6, 90 degree elbows. It is all piped on 1 inch pvc. The pump recommends 1 and half inch pipes but I would like to know how much flow I will be getting out of this pump with the set-up I have now. I really do not want to change all of my plunbing to 1 and a half inch. Will the amp3000 give me good flow or do I need a higher model.

Thank you

The amp master is not rated for pressure, but if you look at their site, i shows that you can get 42GPM at 8' of head

If you use 1" you will basically be wasting the ampmaster. According to the makers... plubing the unit from 1.5" down to 2 1" outlets (thats two) it reduces the flow from 3000 to 1500. so I can only imagine what the 1" plus all the elbows and the tall height would do to it. I would say probably not worth it. I would consider and Iwaki 70. They are 1" and rated for pressure.
