The System We Install

Charger Scale Prep SP3

Scale Prep SP3 is Charger's TAC (Template-Assisted Crystallization) salt-free conditioner. Instead of stripping minerals out of your water, it converts the calcium and magnesium into microscopic crystals that pass through your plumbing harmlessly — preventing scale buildup without ion exchange, salt, or waste water.

  • Zero salt — no monthly salt bags to lift, no salt residue on glassware or in your dishwasher
  • Zero waste water — unlike salt softeners that dump 25-100 gallons per regen, the SP3 wastes nothing
  • Zero electricity — no controller to fail, no programming, no power draw
  • Preserves calcium and magnesium minerals in your drinking water (these are healthy, just hard on appliances)
  • Best fit for sodium-restricted diets, eco-conscious homeowners, and homes without a nearby drain

Salt-Free FAQs

Common questions, straight answers

How much does a salt-free water conditioner cost installed in Prescott AZ?
$3,950 installed in Prescott. Covers the Scale Prep SP3 system sized to your home water profile and household demand, the Clack WS1 valve, TAC media, all parts and fittings, and up to 2 hours of loop plumbing. Anything beyond 2 hours runs $179 an hour. No drain plumbing needed — the SP3 doesn't backwash or regenerate. Before parts are ordered, the configuration is confirmed with Charger's engineering team based on your address and water test results.
What is the difference between a salt-free conditioner and a regular water softener?
A regular softener removes calcium and magnesium via ion exchange and replaces them with sodium — that's how it produces 'soft' water that feels slippery. A salt-free conditioner uses TAC (Template-Assisted Crystallization) to convert the calcium and magnesium into microscopic harmless crystals that pass through your plumbing without sticking. Salt-free does not remove hardness — it prevents the scale damage hardness would cause. Glassware will still show some mineral spots, but pipes and water heaters are protected.
Does the SP3 actually work? Is it as good as a salt softener?
For preventing scale buildup in pipes and water heaters, the SP3 is independently tested at 99%+ effective. It's not as good as a salt softener if you want the slippery 'soft' shower feel, soap that lathers easily, or zero mineral spots on glass. Salt softeners win on softness; salt-free wins on simplicity, lower ongoing cost, no salt-runs, no waste water, and no sodium added to your drinking water. We help you pick based on your priorities.
Who should choose salt-free over a salt softener?
Pick the SP3 if you want scale protection without monthly salt runs, no electricity, no waste water, and your drinking water still has its calcium and magnesium. Pick the salt softener if you want the slippery soft-shower feel, spot-free glassware, or you're on Phoenix EPCOR water at 18–23 grains — at that hardness, salt-free can't keep up. Both work. They're built for different priorities.
How long does the SP3 media last?
The TAC media in the Scale Prep SP3 has an expected service life of 5-7+ years under typical conditions. Most homes never replace the media — they replace the whole system when it's time. Unlike salt softeners that need salt every month and resin replacement every 10-15 years, the SP3 has effectively zero ongoing maintenance other than an optional carbon pre-filter swap once a year for chlorinated city water.
Does the salt-free conditioner work on well water?
The Scale Prep SP3 works on well water if iron stays below 0.4 ppm. Most Yavapai County wells fall within that range, but some don't. If your well water has higher iron, sulfur, or arsenic, we install the SP3 downstream of the appropriate iron/sulfur filter ($4,650) or arsenic system ($4,750). We always test the water first before recommending a salt-free solution on a well.
Will I see mineral spots on glassware with salt-free?
Yes, somewhat. The SP3 prevents scale damage to your pipes and appliances but doesn't remove the calcium and magnesium minerals — they're still in the water when it dries on glass. The spots are usually lighter than untreated hard water but still visible. If spot-free glassware is a priority, a salt-based softener is the better choice. For health-conscious homeowners who want their drinking water to keep its mineral content, the SP3 is the answer.
How long does installation take?
Most SP3 installs take 2-3 hours from arrival to walk-through. Because there's no brine tank, no electrical hookup, and no drain plumbing, it's the fastest water-treatment install we do. We coordinate the appointment around your schedule and most installs are completed same-day with no water shutoff longer than 90 minutes.

Ready for scale protection without the salt?

I'll come look at your setup, test your water, and tell you straight whether the SP3 fits your home or whether a salt softener at $3,250 is the better answer. If it's not for you, I'll say so.
