Response from Ben Needham:
Ok so,
Assuming the pump was sized based off of a design flow of approximately 1GPM...
The head loss in your system would be ~ 0.5Ft
If I plot out your system curve overlaid with the 007 pump curve, the actual expected flow would be ~ 4GPM
40 feet of 3/4 inch type L copper will hold ~ 1.016 Gallons
1.016Gal/(4 Gal/Min) ~ apprximitly 15 Seconds
Provided the assumptions are correct.
