The Atla System is designed to operate between 30 PSIG (207 kPa) and 75 PSIG (517 kPa). We recommend that homes exceeded the maximum recommended pressure be fitted with a pressure regulator adjusted to 60 PSIG for the best results.
If your water is over 75 PSIG, the other water-connected appliances in your home (clothes washer, dishwasher, etc.) will also enjoy an extended life with the addition of a pressure regulator.
