Sorry I missed this one initially.
For the closed conduit flow, the flow from the pump back to the tank, use the sizing guideline chart I presented at the April 30 Meeting?
If I understand your set-up correctly, your tank has two, 3/4" inflow-to-tank lines. Also, from whaht I gater, the Ampmaster 3000 pump produces 52gal/min @ 4ft of head. This equals roughly 3000gal/h. I am not sure how high your tank is above the sump. But it seems that to drop to 1400gal/h, you would need something like 14ft of head. Is this a basement sump? Anyhow, introducing the flow with a two, 3/4-in. lines is probably using toio small of a diameter pipe.
If you have 1400gal/h of flow, then you would need a 1.5" line leaving the pump, split to two, 1" lines before reducing to 3/4" at the tank.
If you have 3000gal/h of flow, then you would need a 2.5" line leaving the pump, split to two, 1.5" lines before reducing to 3/4" at the tank.
Clearly, having 3000gal/h would be excessive. The pump wpuld need to be throttled back,
