Questions, answered
How is the Nexxus installed?
The Nexxus mounts vertically on your main incoming water line (point of entry) with 10 to 12" of clearance below the housings for filter service. It uses 1" NPT connections; an upstream shut-off plus a bypass valve are strongly recommended. Operate within 110 PSI and 40 to 125°F. Professional installation by a licensed plumber is recommended. For step by step guidance, see our Nexxus install guide.
