Agree with the other posts. Larger line should not only carry more water but also be more efficient pumping because of less internal flow resistance. Rule of thumb is if you double the size of the pipe you will quadruple the flow. 2" line flows 4x the water of a 1" line, all other things being equal.
waterline?
