- [About RO GPD Ratings] GPD ratings are based on tests performed under specific water conditions (Urban tap water, 25°C / 77 °F, 100 PSI). Every time the temperature drops by 1°C / 33.8°F, the GPD Rating drops by about 3-4%.
- every time the pressure drops by 1 PSI, the GPD Rating drops by about 1 - 1.5%. For example, a standard 400 GPD RO membrane, at a temperature of 10°C / 50°F (or a pressure of 50 PSI), the GPD Rating is about 200..
