Does anyonk know how the ebay "waterguy" maple RO 7500 GPD model gets its numbers? I look at the membranes (2) and operating pressures (225PSI) and don't get __ANYWHERE__ near the numbers claimed, which would be 300+GPH. The best I can get from the most efficient membrane I can find (xle4040) is 125GPH running at 300PSI, 2% in, 9% out at 40F feed at max cross flow. I'd be interested to learn his secret, if there is one.
