North Star epawcs Salt-free Anti-scale System 4.0 Gpm

Product Description

The NORTH STAR epawcs is a salt-free, whole-house anti-scale system designed for residential water treatment. It uses anti-scale filter media to condition hard water without the use of salt or chemicals, reducing scale buildup inside pipes, fixtures, and water-using appliances. The system delivers treated water to every outlet in the home at a flow rate of 4.0 gallons per minute (GPM). With 1-inch MNPT inlet and outlet connections and a compact footprint, it installs on the main supply line and services the entire household. Filter media requires replacement every 6 months to maintain performance. Licensed plumbers and experienced DIYers typically handle installation.

The epawcs is suited for residential applications where hard water scale is causing buildup in supply lines, water heaters, fixtures, and appliances. It is sized for whole-house service, making it appropriate for typical single-family homes. The system operates across a wide range of supply conditions, functioning at pressures from 30 to 100 psi and water temperatures from 40 to 100 degrees F, covering most municipal and well-water supply scenarios. No drain line, electricity, or brine tank is required, simplifying installation compared to ion-exchange softener systems.

Installation Notes

Installation on the main cold-water supply line should be performed by a licensed plumber in compliance with local plumbing codes and IPC guidelines. Shut off the main water supply and relieve system pressure before cutting into the supply line. Use appropriate thread sealant on all NPT connections and verify the flow direction arrow on the housing is oriented correctly before pressurizing the system. Do not install on hot water lines or in locations where water temperature or pressure may exceed the rated operating range.
