Nelsen Scale Prevention System

Protect your home's plumbing and fixtures from limescale without salt, slippery water, or wasted water using the Nelsen Scale Prevention System, model NSPS-0844. Supplied by Water Softener Plus, this compact whole-house system uses Filtersorb SP3 media to transform hardness minerals so they can no longer form sticky, damaging scale, all while leaving the water's natural mineral content in place for you to enjoy.

How Salt-Free Scale Prevention Works

Rather than removing calcium and magnesium through ion exchange like a traditional softener, Filtersorb SP3 uses template-assisted crystallization to convert dissolved hardness minerals into stable, microscopic crystals. These crystals pass harmlessly through your plumbing instead of adhering to pipes, water heaters, and fixtures as scale. The result is genuine scale protection with no salt to buy and carry, no brine to discharge, and no electricity required to run the system, a low-maintenance, environmentally friendly approach.

• Filtersorb SP3 media for salt-free scale prevention
• Enpress mineral tank with Vortech bottom distribution plate
• C-Series in/out head and C-Series bypass valve
• 1" NPT PVC plumbing adapters for straightforward installation
• 1" x 10" Big Blue housing with GAC pre-filter included
• Mounting bracket included for the pre-filter housing

The Enpress mineral tank's Vortech bottom distribution plate promotes efficient, even flow through the media bed, helping the system perform reliably while reducing pressure loss. The included 1" x 10" Big Blue housing with granular activated carbon pre-filter handles chlorine, taste, and sediment ahead of the scale-prevention media, which both improves your water quality and protects the media itself from chlorine and debris. As the entry-level size in the NSPS residential lineup, the NSPS-0844 is well suited to smaller homes that want effective, eco-friendly scale control without the ongoing salt and maintenance demands of a conventional softener.

Salt-free conditioning is especially appealing for households on a sodium-restricted diet, for homes with septic systems where brine discharge is a concern, and for anyone who simply dislikes the maintenance routine of hauling and refilling softener salt. Because there is nothing to recharge or regenerate, the system runs quietly in the background with little more than occasional pre-filter changes. Compact and efficient, the NSPS-0844 brings the benefits of modern scale prevention to smaller homes, protecting water heaters, fixtures, and pipes from costly scale buildup the clean, low-maintenance way, backed by Water Softener Plus.
