GPD...What does it stand for?

[ed99]

I get just over 25 gpd off the tap here in Calgary with my 25 gpd rated RO unit. As mentioned in earlier posts the pressure and temperature of the water will affect the throughput. Warmer temperatures will mean higher throughput but also more slippage of the impurities you're trying to get rid of. Higher pressure will also give higher throughputs without hurting performance too much, but the membrane may not last as long if the pressure gets too high.
