What range of water pressure can this system handle?

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.
