North Star Water Conditioning nsc3118 Water Softener 31300 Grains

Product Description

The NORTH STAR WATER CONDITIONING nsc3118 is a point-of-entry grain water softener designed for whole-home installation in medium to large households. It delivers a service flow rate of 7.2 gallons per minute and an intermittent peak flow rate of 11.8 gallons per minute, making it capable of handling the demand of larger residences without pressure drop at fixtures. The unit holds 31,300 grains of softening capacity and stores 12.9 pounds of salt in the integrated brine tank. Operating pressure range is 20 to 125 psi. A high-flow bypass valve is included, allowing service isolation without interrupting supply to the building.

This softener is sized for medium to large household applications where hard water causes scale buildup in water heaters, boilers, plumbing fixtures, and appliances. It installs at the main water service entry point, treating all water entering the structure before it reaches any distribution branch. The 31,300-grain capacity supports extended regeneration cycles appropriate for households with moderate to high daily water consumption. Licensed plumbers typically handle point-of-entry softener installations, particularly where local codes require permitted work on the main service line.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code where adopted. Shut off the main water supply and relieve line pressure before making any connections to the inlet or outlet ports. Use the included high-flow bypass valve to isolate the softener during initial startup, backwash setup, or future service. Verify that drain line routing, brine tank placement, and electrical requirements for the control valve meet local code requirements before commissioning the unit.
