Best Water Softener for Dallas, TX — 17 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Dallas, TX

Every month, Dallas homeowners unknowingly spend an extra $127 fighting their own water supply. This isn't a utility bill increase or a conservation fee — it's the hidden cost of living with 10 grains per gallon (GPG) of water hardness, a mineral concentration that places Dallas firmly in the "very hard" water category.

Picture your home's plumbing system like a network of arteries. At 10 GPG, dissolved calcium and magnesium minerals act like cholesterol, gradually coating pipe walls and choking off water flow. What starts as invisible mineral buildup becomes visible scale, appliance failure, and thousands in premature replacement costs.

Dallas draws its water primarily from surface reservoirs including Lake Ray Hubbard, White Rock Lake, and the Trinity River system. These limestone-rich watersheds naturally dissolve calcium carbonate as water flows through North Texas geology. The result is water that measures 10 GPG — nearly double the threshold where mineral damage becomes financially significant for homeowners.

To understand what 10 GPG means in practical terms, imagine dissolving 10 grains of salt in every gallon of water flowing through your home. A four-person Dallas household consumes roughly 300 gallons daily, meaning 3,000 grains of hardness minerals flow through your plumbing every single day. Over a year, that's more than one million grains of calcium and magnesium deposits seeking places to crystallize and accumulate.

The financial stakes extend far beyond monthly utility costs. Dallas homes with untreated 10 GPG water see water heater efficiency drop 25-30% within two years. Dishwashers fail 18 months sooner than the manufacturer warranty period. Washing machines require replacement every 8-9 years instead of the expected 12-15 year lifespan.

For Dallas families, this isn't just about water quality — it's about protecting the single largest investment most people make in their lifetime. Your home's value depends on functioning infrastructure, and at 10 GPG, that infrastructure is under constant mineral assault.

2. What 10 GPG Does to Your Home

At 10 GPG, calcium carbonate doesn't just coat your fixtures — it systematically destroys your home's water-using systems from the inside out. Understanding the specific damage timeline at this hardness level helps Dallas homeowners grasp why water softening is infrastructure protection, not luxury.

Your water heater bears the heaviest burden under 10 GPG conditions. When water temperatures exceed 140°F, dissolved calcium and magnesium precipitate out of solution, forming concentric rings of scale on heating elements and tank walls. This process happens faster in Dallas than in moderate hardness cities because 10 GPG provides abundant raw material for scale formation.

The efficiency loss follows a predictable pattern at 10 GPG hardness. Month 1-6: Scale begins forming microscopic layers, efficiency drops 5-8%. Month 7-18: Visible white buildup appears, efficiency drops 15-20%. Month 19-36: Thick scale creates insulation barrier, efficiency drops 25-30%. After three years of 10 GPG exposure without treatment, many Dallas water heaters operate at less than 70% of their rated capacity.

Dallas homes built before 1990 often contain galvanized steel pipes, which suffer accelerated deterioration under 10 GPG conditions. Iron pipes develop internal scale buildup that reduces diameter by 10-15% within five years at this hardness level. The narrowed passages create pressure drops, reduce flow rates, and harbor bacteria in the porous scale deposits.

Appliance manufacturers recognize the 10 GPG threshold as a critical damage point. Many tankless water heater warranties become void without a water softener when hardness exceeds 7 GPG. At 10 GPG, the mineral buildup happens so rapidly that heat exchangers can fail within 18-24 months of installation.

The soap and detergent waste at 10 GPG hardness creates measurable monthly expenses for Dallas families. Calcium and magnesium ions react with soap molecules to form insoluble precipitates — the gray scum that clings to shower walls instead of washing down the drain. This chemical reaction means Dallas households need 3-4 times more soap, shampoo, and laundry detergent to achieve the same cleaning results as families with soft water.

For a typical Dallas family of four, the extra soap and detergent costs add up to $35-45 monthly. Over ten years, that's $4,200-$5,400 in unnecessary household chemical expenses — just to compensate for 10 GPG mineral interference.

The skin and hair effects become noticeable at 10 GPG hardness because calcium ions actively strip moisture from skin cells. Dermatologists report that eczema, dry skin, and scalp irritation worsen measurably when water hardness exceeds 7 GPG. Hair becomes dull and brittle as mineral deposits coat the hair shaft, preventing moisture penetration and natural oil distribution.

Dallas residents frequently notice their white clothing turns gray after 6-12 months of washing in 10 GPG water. The calcium and magnesium deposits embed in fabric fibers, creating a permanent mineral coating that makes clothes feel rough and look dingy. Fabric softener provides temporary relief but cannot remove the embedded minerals — only ion exchange water treatment can prevent this buildup.

Adding up the combined costs — energy waste, appliance depreciation, soap waste, clothing replacement, and plumbing repairs — the average Dallas household pays an estimated $1,520 annually in hard water expenses at 10 GPG. This "hardness tax" compounds year after year, making water softening one of the most cost-effective home improvements available to Dallas families.

3. Dallas's Specific Contaminant Profile

Beyond the 10 GPG baseline hardness, Dallas water presents two additional treatment challenges: chloramine disinfection and fluoride supplementation. Each contaminant interacts with the high mineral content in ways that affect taste, odor, and treatment system selection for Dallas homeowners.

Chloramine in Dallas Water

Dallas Water Utilities switched from chlorine to chloramine disinfection in 2009 to reduce disinfection byproducts and maintain residual protection throughout the extensive distribution system. Chloramine is a more stable disinfectant than chlorine, but it's also significantly more difficult to remove from water. The compound forms when ammonia is added to chlorinated water, creating monochloramine, dichloramine, and trichloramine species.

At 10 GPG hardness, chloramine interacts with calcium and magnesium scale deposits in home plumbing systems, creating taste and odor compounds that intensify over time. Many Dallas residents describe their water as having a "band-aid" or medicinal taste, particularly from fixtures with heavy mineral buildup. The chloramine becomes more concentrated as it reacts with accumulated scale, explaining why the taste often worsens in older Dallas homes.

The EPA maximum residual disinfectant level for chloramine is 4.0 mg/L, and Dallas typically maintains levels between 1.5-3.0 mg/L throughout the distribution system. While these levels meet all federal safety standards, chloramine requires specialized carbon filtration for removal — standard activated carbon filters used for chlorine are ineffective against chloramine.

Important for Dallas homeowners: the SoftPro Elite HE water softener removes hardness minerals but does not remove chloramine. For taste and odor improvement, a catalytic carbon whole-house filter paired with the SoftPro provides comprehensive treatment. Chloramine is also toxic to fish and must be removed from aquarium water using appropriate dechloraminators.

Fluoride in Dallas Water

Dallas Water Utilities adds fluoride to the municipal supply at the EPA-recommended level of 0.7 mg/L for dental health benefits. The fluoride addition occurs at treatment plants before distribution, ensuring consistent levels throughout Dallas neighborhoods. This practice follows American Dental Association guidelines and CDC recommendations for community water fluoridation.

Fluoride doesn't directly interact with 10 GPG water hardness, but the combination affects treatment system selection. Water softeners using ion exchange resin do not remove fluoride from water. The fluoride ions pass through the softening process unchanged, maintaining the intended 0.7 mg/L concentration in softened water.

The EPA maximum contaminant level for fluoride is 4.0 mg/L (health-based) and 2.0 mg/L (aesthetic-based, to prevent dental fluorosis). Dallas water fluoride levels are well below both thresholds and remain within the optimal range recommended by public health authorities. For Dallas residents with specific concerns about fluoride consumption, reverse osmosis systems at the kitchen tap provide effective removal while preserving the water softening benefits throughout the rest of the home.

For comprehensive Dallas water treatment, homeowners typically need a two-stage approach: the SoftPro Elite HE for hardness removal, plus point-of-use carbon filtration for chloramine if taste and odor improvement is desired. This combination addresses all three primary characteristics of Dallas municipal water — hardness, chloramine, and fluoride considerations.

4. Why Most Dallas Homeowners Pick the Wrong Softener

Walk into any Dallas home improvement store and you'll find water softeners marketed as "one-size-fits-all" solutions. But at 10 GPG hardness with chloramine and fluoride present, generic sizing and feature selection often leads to system failure, salt waste, and continued hard water damage.

The first mistake happens at the cash register. Dallas families facing $300 monthly hard water damage costs often choose a $400 softener over a $1,200 system, thinking they're saving money. At 10 GPG, an undersized 24,000-grain unit designed for moderate hardness cities will exhaust its resin capacity in 2-3 days instead of the intended week. The constant regeneration cycles waste salt, waste water, and leave gaps where hard water breaks through during peak usage periods.

The second mistake stems from confusion about what water softeners actually treat. Softeners remove calcium and magnesium through ion exchange — they do not remove chloramine or fluoride. Dallas homeowners who install a softener expecting complete water purification discover that taste, odor, and chemical concerns remain unchanged. The disappointment often leads to negative reviews of perfectly functional softening systems.

Grain capacity mathematics trips up many Dallas buyers. The calculation seems simple: multiply people times gallons times GPG. But most retailers don't explain that regeneration efficiency matters enormously at 10 GPG hardness. A 4-person Dallas household needs 300 gallons × 10 GPG = 3,000 grains removed daily, or 21,000 grains weekly. Add a 20% buffer for high-usage days, and you need 25,200 grains minimum. A 32,000-grain softener seems adequate, but only if it regenerates at optimal efficiency.

The fourth mistake costs Dallas homeowners hundreds annually in unnecessary salt purchases. At 10 GPG hardness, regeneration frequency increases compared to moderate hardness cities. A salt-efficient softener uses 6-8 pounds per regeneration cycle, while an inefficient model uses 15-20 pounds for the same grain capacity reset. Over 10 years in Dallas, this difference compounds to $800-1,200 in extra salt costs — often exceeding the initial price difference between economy and high-efficiency models.

5. What to Do Next

Before shopping for any water softener, test your specific Dallas water hardness at home. While city-wide averages show 10 GPG, individual neighborhoods can vary from 8-12 GPG depending on distribution system age and seasonal factors.

Purchase a TDS (total dissolved solids) meter and hardness test strips from a hardware store. Test your water at different times — morning, evening, and after periods of high neighborhood usage. Record the results over one week to identify any patterns or variations.

Calculate your household's actual daily water usage by reading your water meter before and after a 24-hour period when you're home. Multiply the gallon difference by your tested GPG hardness to determine your real grain removal demand. This calculation is more accurate than the standard 75-gallons-per-person estimate used by most retailers.

6. Homeowner Checklist

Walk through your Dallas home and document current hard water damage to establish a baseline. Take photos of water heater scale, faucet deposits, shower door spots, and appliance interiors. This documentation helps track improvement after softener installation.

Check your water heater's manufacture date and efficiency rating. If it's older than 3 years and shows heavy scale buildup, factor replacement savings into your softener investment calculation. Many Dallas homeowners discover that preventing premature water heater replacement pays for the softener system entirely.

Review your homeowner's insurance and appliance warranties. Some policies require water treatment systems when hardness exceeds certain thresholds. Document this requirement to support your softener purchase decision.

7. The SoftPro Elite HE: Built for Dallas's Water

After evaluating Dallas's water hardness of 10 GPG and the presence of chloramine and fluoride in the local supply, one system consistently rises to the top for Dallas homeowners: the SoftPro Elite HE Water Softener. This recommendation isn't based on marketing claims — it's based on matching system capabilities to Dallas's specific water chemistry challenges.

The foundation of effective water softening at 10 GPG hardness is genuine ion exchange, not alternative technologies that claim to "condition" or "restructure" minerals. Salt-free systems do not remove calcium and magnesium from water — they attempt to change crystal structure to reduce scale adhesion. At 10 GPG, this approach cannot prevent the accumulation and damage that Dallas homeowners face daily. The SoftPro Elite HE uses true cation exchange resin to physically replace every calcium and magnesium ion with sodium, delivering genuinely soft water that measures under 1 GPG.

Demand-initiated regeneration (DIR) technology becomes operationally essential at Dallas's hardness level. Traditional timer-based systems regenerate on fixed schedules regardless of actual water usage or resin exhaustion. At 10 GPG, this approach either wastes salt and water through unnecessary regeneration, or allows hard water breakthrough when usage exceeds the programmed assumptions. The SoftPro's DIR system monitors actual water flow and grain removal, regenerating only when the resin approaches capacity depletion.

For Dallas households managing 10 GPG hardness, regeneration timing precision prevents the most common softener complaint: intermittent hard water. During regeneration cycles, the system temporarily bypasses untreated water while the resin resets. DIR ensures these cycles happen during predictable low-usage periods, typically between 2-4 AM when Dallas families are asleep and appliances aren't running.

The NSF/ANSI Standard 44 certification provides Dallas homeowners with verified performance data rather than marketing promises. This certification requires independent testing of grain capacity, regeneration efficiency, and materials safety. For Dallas residents already managing chloramine and fluoride in their water supply, knowing the softening process itself doesn't introduce additional contaminants or leach unsafe materials becomes critically important.

Grain capacity selection at 10 GPG hardness requires precise sizing to avoid over-investment or under-performance. The SoftPro Elite HE offers 32K, 48K, 64K, and 80K grain capacity options, allowing Dallas homeowners to match system size to actual household demand. A 4-person Dallas household with 300 daily gallons needs 3,000 grains removed daily, or 21,000 weekly. The 48K capacity tier provides optimal regeneration frequency of every 5-7 days, maximizing salt efficiency while preventing resin exhaustion.

The 10-year warranty coverage addresses the reality of high-hardness operation in Dallas. At 10 GPG, resin sees heavy daily mineral exchange cycles that don't occur in moderate hardness cities. Electronic components, control valves, and bypass mechanisms experience more frequent operation under these demanding conditions. The extended warranty provides Dallas homeowners with protection during the years when 10 GPG stress is highest on system components.

System compatibility matters for Dallas water treatment because chloramine removal requires supplemental carbon filtration. The SoftPro Elite HE is designed to work effectively upstream or downstream of carbon filters, providing installation flexibility for comprehensive treatment. Many Dallas homeowners pair the SoftPro with a whole-house carbon system for complete hardness and taste/odor management.

For Dallas households dealing with 10 GPG of water hardness and the compounding presence of chloramine and fluoride, the SoftPro Elite HE is not a comfort upgrade — it is infrastructure protection for your home.

8. Recommended Setup for Dallas

The optimal Dallas water treatment configuration addresses hardness, chloramine, and fluoride concerns through strategic system placement. Install the SoftPro Elite HE as the primary system immediately after your main water shutoff valve, before any branch lines to appliances or fixtures.

For comprehensive treatment, add a whole-house catalytic carbon filter upstream of the SoftPro to remove chloramine before it contacts the softener resin. This sequence prevents chloramine interference with the ion exchange process and extends resin life. The carbon system also eliminates the medicinal taste and odor that many Dallas residents notice, especially during summer months when chloramine levels peak.

Size the 48K grain capacity SoftPro Elite HE for typical Dallas households of 3-5 people. This capacity handles 10 GPG hardness with regeneration every 5-7 days, optimizing salt efficiency and water quality consistency. Larger households or homes with high water usage should consider the 64K capacity tier.

9. How to Size Your Softener for Dallas

Proper sizing at 10 GPG hardness prevents the most common Dallas softener problems: frequent regeneration, salt waste, and hard water breakthrough during peak usage. Follow this step-by-step calculation to determine the right SoftPro Elite HE capacity for your household.

Step 1: Count household members including children and regular overnight guests. Step 2: Multiply by 75 gallons per person per day (the EPA average for indoor water use). Step 3: Multiply household gallons × 10 GPG = daily grain demand. Step 4: Multiply daily grains × 7 = weekly grain demand. Step 5: Add 20% buffer for high-usage days like laundry and bathing overlap. Step 6: Match your total to the appropriate SoftPro Elite HE grain tier.

Here's the calculation worked out for a typical 4-person Dallas household: 4 people × 75 gallons = 300 gallons daily. 300 gallons × 10 GPG = 3,000 grains daily. 3,000 grains × 7 days = 21,000 grains weekly. 21,000 grains × 1.20 buffer = 25,200 grains needed.

The 32K capacity provides 32,000 grains, which seems adequate but only allows 7-8 days between regeneration with no usage buffer. The 48K capacity provides 48,000 grains, allowing regeneration every 9-10 days with comfortable buffer for high-usage periods. This regeneration frequency optimizes salt efficiency and ensures consistent soft water availability during peak demand times.

Dallas households with swimming pools, large gardens, or teenagers should consider the 64K capacity tier. Pool filling, landscape irrigation, and teenage shower habits can double normal usage during certain periods. The larger capacity prevents hard water breakthrough during these high-demand situations.

10. Installation in Dallas: What to Know

Dallas doesn't require licensed plumbers for water softener installation, but the city does require compliance with the Texas State Plumbing Code for all permanent plumbing modifications. Most Dallas homeowners can legally install softeners themselves, though professional installation ensures proper drain connections and code compliance.

Locate the SoftPro Elite HE after your main water shutoff valve but before the water heater and any branch lines. The system needs 110V electrical power and a drain connection within 20 feet for regeneration discharge. Dallas municipal code allows softener discharge to connect to laundry drains, utility sinks, or floor drains — but not directly to septic systems if your property uses one.

Dallas municipal water pressure typically ranges from 45-65 PSI throughout the distribution system, which falls within the SoftPro Elite HE's optimal operating range of 25-80 PSI. No pressure regulation is needed for most Dallas installations, though homes in elevated areas may see lower pressures during peak usage periods.

At 10 GPG hardness, use evaporated salt pellets exclusively — avoid rock salt or solar crystals in Dallas installations. Evaporated pellets provide the highest purity and lowest brine tank residue, essential for maintaining resin efficiency under heavy mineral removal demands. Lower-grade salts contain insoluble materials that accumulate faster at high regeneration frequencies.

Check salt levels monthly during your first year of operation at 10 GPG hardness. A 48K capacity system serving a 4-person Dallas household typically consumes 40-50 pounds of salt monthly, significantly higher than households with moderate hardness. Maintain salt levels above the water line in the brine tank to prevent salt bridging — a solid crust that blocks regeneration.

11. 30-Day Action Plan

Week 1: Document your current hard water costs and damage throughout your Dallas home. Photograph scale buildup, test water hardness, and calculate monthly soap and detergent expenses. Review your last 12 months of utility bills to establish baseline energy costs for water heating.

Week 2: Size the appropriate SoftPro Elite HE capacity using the calculation method from Section 9. Contact three Dallas water treatment dealers for installation quotes, ensuring they include proper drain connections and electrical requirements. Verify local permit requirements with Dallas building department if you plan professional installation.

Week 3: Order the SoftPro Elite HE system and schedule installation. Purchase evaporated salt pellets and water hardness test strips for post-installation verification. Prepare the installation area by clearing access to main water lines and identifying appropriate drain connections.

Week 4: Complete installation and system startup. Test post-softener water hardness within 48 hours to confirm proper operation — results should show less than 1 GPG. Document the installation date and begin monthly maintenance schedule tracking.

12. Maintenance Schedule for Dallas Homeowners

High hardness operation at 10 GPG requires more frequent maintenance attention than softeners in moderate hardness cities. This schedule prevents the most common problems Dallas homeowners encounter with their water softening systems.

Monthly maintenance tasks include checking salt levels and inspecting for salt bridges — solid crusts above the water line that prevent proper brine formation. At 10 GPG hardness, salt consumption is high, typically 40-50 pounds monthly for a 4-person household. Maintain salt levels 4-6 inches above the water line, but don't overfill the tank beyond the manufacturer's maximum level indicator.

Every three months, clean the brine tank to remove accumulated sediment and verify the salt platform hasn't shifted. Test post-softener water hardness using test strips — results consistently above 1 GPG indicate potential resin exhaustion or regeneration problems. Check that the bypass valve remains in the service position and hasn't been accidentally switched to bypass mode.

Annual maintenance becomes critical for Dallas systems handling 10 GPG hardness year-round. Perform complete brine tank cleaning, removing all salt and scrubbing interior surfaces to eliminate bacteria and algae growth. Inspect the resin tank for signs of channeling — uneven water flow patterns that reduce softening efficiency. If post-softener hardness creeps above 1 GPG despite proper salt levels, the resin may need professional cleaning or replacement.

Every five years, evaluate resin performance through professional water testing and system inspection. At 10 GPG, resin experiences heavy mineral exchange cycles that gradually reduce capacity and efficiency. High-hardness cities like Dallas typically see resin degradation faster than soft-water locations. Budget for potential resin replacement at the 8-10 year mark depending on usage patterns and maintenance consistency.

Dallas residents should establish a baseline hardness reading before installation and retest monthly during the first year to verify consistent system performance. Keep maintenance records including salt usage, regeneration frequency, and any service calls — this documentation helps identify patterns and prevents major problems.

13. Frequently Asked Questions for Dallas Residents

13. Is Dallas's water at 10 GPG dangerous to drink?

No, 10 GPG hardness does not create health risks for Dallas residents. Calcium and magnesium are essential minerals that many people supplement through diet or vitamins. The EPA does not regulate water hardness as a health concern — the 10 GPG classification as "very hard" refers to property damage and soap effectiveness, not safety. Dallas municipal water meets all federal drinking water standards for health protection.

14. Will a water softener remove chloramine from Dallas water?

No, the SoftPro Elite HE removes calcium and magnesium hardness but does not remove chloramine disinfectant. Chloramine requires specialized catalytic carbon filtration for effective removal. Dallas homeowners wanting comprehensive treatment should pair the SoftPro with a whole-house carbon system. Standard activated carbon filters used for chlorine removal are not effective against chloramine — only catalytic carbon provides reliable removal.

15. How much salt will I use per month in Dallas at 10 GPG?

A typical 4-person Dallas household will use 40-50 pounds of salt monthly with a properly sized SoftPro Elite HE system. This calculation assumes 300 gallons daily usage at 10 GPG hardness with regeneration every 5-7 days. Larger households or higher water usage increases salt consumption proportionally. Use evaporated salt pellets exclusively — lower-grade salts waste money and reduce efficiency at high hardness levels.

16. Does Dallas require a permit to install a water softener?

Dallas does not require specific permits for water softener installation, but the work must comply with Texas State Plumbing Code requirements. Professional installation typically includes code compliance as part of the service. DIY installations must ensure proper drain connections and electrical safety. Contact Dallas building department if your installation involves major plumbing modifications or new electrical circuits.

17. Why does soft water feel slippery in the shower?

Soft water feels slippery because your skin is actually clean for the first time in years. At 10 GPG hardness, calcium ions bond with soap to form sticky residue that clings to skin, creating a false sense of "clean" feeling. Truly soft water allows soap to rinse completely, leaving skin naturally smooth and moisturized. Dallas residents typically adjust to the sensation within 1-2 weeks of softener installation.

18. How quickly will I see results after installing a softener in Dallas?

At 10 GPG hardness, Dallas homeowners notice immediate improvements in soap lather and reduced spotting on dishes and glassware. Existing scale deposits throughout your plumbing system take 3-6 months to gradually dissolve and flush away. Water heater efficiency improvements become measurable after 6-12 months as scale deposits clear from heating elements. Skin and hair improvements typically appear within 2-3 weeks of consistent soft water use.

19. Can the SoftPro Elite HE handle Dallas's water without a separate filter?

The SoftPro Elite HE effectively removes 10 GPG hardness without additional filtration, but taste and odor concerns from chloramine require supplemental carbon treatment. For hardness removal alone, the SoftPro provides complete protection against scale, appliance damage, and soap waste. Dallas homeowners who want comprehensive water improvement typically add whole-house carbon filtration for chloramine removal and better taste. Fluoride removal requires reverse osmosis systems at specific taps if desired.

20. Final Verdict for Dallas

Dallas's water hardness of 10 GPG demands professional-grade water treatment to protect your home's infrastructure and your family's budget. The "very hard" classification isn't just a technical measurement — it's a warning that untreated water will cost Dallas homeowners thousands in premature appliance replacement, energy waste, and ongoing maintenance problems.

Chloramine disinfection and fluoride supplementation compound the hardness problem by requiring specialized filtration knowledge and system compatibility considerations. Generic box-store softeners designed for moderate hardness cities cannot handle Dallas's demanding water conditions reliably.

The SoftPro Elite HE provides the right solution because its demand-initiated regeneration prevents hard water breakthrough during high usage periods, its NSF-certified resin handles heavy 10 GPG mineral exchange cycles, and its 10-year warranty protects Dallas homeowners during the years of highest operational stress. The 48K grain capacity matches typical Dallas household demand with optimal regeneration efficiency.

Check current SoftPro Elite HE pricing and available grain capacities for Dallas installation. Review system specifications and warranty coverage to confirm the investment matches your household's specific water usage patterns.

From the limestone aquifers that feed Lake Ray Hubbard to the sprawling suburbs of Plano and Richardson, Dallas-area homeowners share the same 10 GPG challenge — and the same opportunity to protect their most valuable investment with proven water softening technology.
