I think in that case it's a matter lacking information. You could say those things if you ignored certain real-world issues. "No more flow" = no more than the pumps max rating, "tehy pull twice as much water" = [when there is no resistance in the system]. That then brings up the more important issue, IMO - no drive-by posting. EXPLAIN yourself so that even your mom would understand...in another forum we had a problem with "pc+1" spam - postcount+1 nonsense replys.
