Best Water Softener for Phoenix, AZ — 17 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Sonoran Desert's Hidden Home Destroyer

Walk through any Phoenix neighborhood built before 2010, and you'll find a troubling pattern hidden behind desert-modern facades and palm-lined driveways. Inside these homes, water heaters are failing at twice the national average rate, dishwashers are replaced every 6-7 years instead of 12, and homeowners are spending $400-600 annually on extra soap, scale removers, and emergency plumber calls. The culprit isn't Arizona's legendary heat—it's what flows through every tap, shower, and appliance in the Valley of the Sun.

Phoenix's municipal water supply registers 12.3 grains per gallon (GPG) of dissolved calcium and magnesium minerals. To put this number in perspective using a cooking analogy, imagine adding nearly two tablespoons of chalk dust to every gallon of water that enters your home. At 12.3 GPG, Phoenix water is classified as "extremely hard" by water quality standards—placing it among the most mineral-dense municipal supplies in the United States.

This hardness level stems from Phoenix's primary water sources: the Salt and Verde Rivers, which flow through limestone and gypsum deposits in central Arizona's mountain ranges, plus groundwater drawn from aquifers that have absorbed minerals from ancient seabeds over millennia. The Colorado River water delivered through the Central Arizona Project adds its own mineral load after traveling through the Grand Canyon's limestone corridors.

For Phoenix homeowners, 12.3 GPG isn't just a water quality statistic—it's a home value threat. Every day this extremely hard water circulates through your plumbing system, it deposits calcium carbonate scale that narrows pipes, coats heating elements, and creates the perfect environment for bacterial growth. The financial stakes are immediate: Phoenix households lose an estimated $1,200-1,800 annually to hard water damage, wasted energy, and premature appliance replacement.

2. What 12.3 GPG Does to Your Phoenix Home

At Phoenix's extreme 12.3 GPG hardness level, calcium carbonate doesn't just coat your pipes—it builds concentric mineral rings that can reduce water flow by 40% within five years. This isn't the gradual scale buildup that homeowners in moderately hard water cities experience over decades. In Phoenix, the mineral assault on your home's infrastructure happens in fast-forward.

Your water heater bears the worst damage. When Phoenix's 12.3 GPG water is heated to 120°F, dissolved calcium and magnesium ions crystallize instantly onto heating elements and tank walls. A standard 40-gallon electric water heater loses 8-12% efficiency within the first year of Phoenix service, and 35-45% efficiency within 24 months. Gas water heaters fare slightly better but still see 25-30% efficiency loss by year two. Phoenix plumbers report water heater lifespans averaging 6-8 years versus the national average of 10-12 years.

The mineral deposits create insulation layers that force heating elements to work harder, driving up your monthly SRP or APS electric bills. A Phoenix household with a scale-clogged water heater typically pays $200-350 more annually in energy costs compared to the same home with softened water. The minerals also create hot spots on heating elements, leading to premature burnout and costly emergency repairs during Phoenix's scorching summer months when you can least afford to lose hot water.

Phoenix's older neighborhoods face amplified pipe damage. Homes built before 1990 with galvanized steel plumbing see measurable flow restriction within 3-4 years at 12.3 GPG. The scale bonds with iron oxide in aging pipes, creating rough surfaces that catch more minerals in a compounding cycle. Copper pipes last longer but develop pinhole leaks when scale buildup creates pressure points and galvanic corrosion.

Appliance destruction accelerates dramatically at Phoenix's hardness level. Dishwashers in Phoenix homes average 6-7 years of service life compared to 12+ years in soft water cities. The minerals clog spray arms, coat sensors, and etch permanent white spots into the interior glass that no amount of cleaning can remove. Washing machines suffer bearing damage when mineral-stiffened fabrics create unbalanced loads, and the heating elements fail from scale buildup just like water heaters.

The "Phoenix hard water tax" compounds daily through soap and detergent waste. At 12.3 GPG, calcium and magnesium ions chemically bond with soap molecules to form insoluble scum rather than cleaning lather. Phoenix families typically use 3-4 times more laundry detergent, dish soap, and shampoo compared to households with soft water. The annual extra cost ranges from $300-500 for a typical four-person Phoenix household.

Personal care becomes a daily frustration at 12.3 GPG. The mineral ions strip natural oils from skin and hair, leaving Phoenix residents with chronically dry skin despite the city's low humidity. Hair feels coarse and looks dull because calcium deposits coat each strand. Children with sensitive skin or eczema experience noticeably worse symptoms in Phoenix compared to soft water cities.

Laundry emerges stiff, gray, and scratchy as mineral deposits embed in fabric fibers. White clothing takes on a permanent dingy appearance within 6-12 months of Phoenix washing machine use. Towels lose absorbency and feel rough against skin. Even expensive detergents formulated for hard water cannot fully prevent this mineral damage at Phoenix's extreme hardness level.

Adding up energy waste, appliance depreciation, extra cleaning products, and premature replacements, Phoenix households face an annual "hard water tax" of approximately $1,500-2,200 at 12.3 GPG—money that could be saved with proper water treatment.

3. Phoenix's Layered Contaminant Challenge

Phoenix's water profile presents a layered challenge: beyond the 12.3 GPG hardness baseline, residents are also contending with fluoride, chlorine, and nitrates—each of which interacts with water hardness in its own way.

Fluoride in Phoenix Water

Phoenix adds fluoride to its municipal water supply at the CDC-recommended 0.7 mg/L for dental health benefits. This intentional additive comes from either fluorosilicic acid or sodium fluoride compounds introduced at the treatment plant. While fluoride provides documented cavity prevention benefits, some Phoenix residents prefer to control their family's fluoride exposure through toothpaste and professional treatments rather than consuming it in every glass of tap water.

The interaction with Phoenix's 12.3 GPG hardness creates a compounding effect. Fluoride ions can react with calcium in extremely hard water to form calcium fluoride precipitates, which appear as white powdery deposits on glassware and fixtures alongside typical hard water scale. This dual mineral coating makes Phoenix's water spots particularly stubborn and difficult to remove with standard cleaners.

Phoenix residents notice a slightly bitter or metallic aftertaste in tap water, especially when drinking it cold or making coffee and tea. The fluoride remains detectable to sensitive palates even after boiling. The EPA maximum contaminant level for fluoride is 4.0 mg/L for health effects and 2.0 mg/L for cosmetic effects like dental fluorosis. Phoenix's 0.7 mg/L falls well below these thresholds, but the SoftPro Elite HE water softener alone does not remove fluoride—residents seeking fluoride reduction need a reverse osmosis system at their drinking water tap in addition to whole-house softening.

Chlorine in Phoenix Water

Phoenix Water Services adds chlorine as the primary disinfectant to eliminate bacteria, viruses, and other pathogens during treatment and distribution. This chlorine enters Phoenix's supply as either sodium hypochlorite or chlorine gas, with residual levels maintained throughout the distribution system to prevent recontamination.

Chlorine levels fluctuate seasonally in Phoenix, with stronger concentrations during summer months when higher temperatures promote bacterial growth in distribution pipes. Phoenix residents often notice a sharper "swimming pool" smell and taste during July and August when chlorine dosing increases. The chemical also reacts with organic matter in source water to form disinfection byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs), which have their own taste and odor signatures.

The interaction with 12.3 GPG hardness accelerates chlorine's corrosive effects on plumbing. Scale deposits create rough surfaces where chlorine concentrates, leading to faster degradation of rubber gaskets, O-rings, and valve seals throughout Phoenix homes. This is why Phoenix plumbers see more frequent faucet repairs and toilet valve replacements compared to soft water cities.

Phoenix's chlorine levels typically range from 0.5-2.0 mg/L, well below the EPA maximum residual disinfectant level of 4.0 mg/L. The SoftPro Elite HE softener alone does not remove chlorine—Phoenix residents wanting chlorine reduction should pair their softener with an activated carbon whole-house filter or point-of-use carbon filters at kitchen and bathroom sinks.

Nitrates in Phoenix Water

Nitrates enter Phoenix's water supply through agricultural runoff from surrounding Maricopa County farming operations and historical groundwater contamination from fertilizer application. While Phoenix has transitioned much of its water sourcing to surface water from the Colorado River and Salt River system, some wells in the eastern valley still show elevated nitrate levels from decades of intensive agriculture.

Phoenix residents typically cannot detect nitrates through taste, odor, or appearance—it's a colorless, odorless contaminant that requires laboratory testing to identify. The interaction with 12.3 GPG hardness doesn't change nitrate levels, but the combination means Phoenix households dealing with both issues need a comprehensive treatment approach.

The EPA maximum contaminant level for nitrates is 10 mg/L (measured as nitrogen), established primarily to protect infants under six months old who can develop methemoglobinemia ("blue baby syndrome") from elevated nitrate consumption. Pregnant women are also advised to limit nitrate exposure during the first trimester. Phoenix's nitrate levels typically range from 2-6 mg/L in most distribution zones—below the EPA limit but still detectable.

Critical accuracy point: Water softeners do NOT remove nitrates. The ion exchange resin in the SoftPro Elite HE specifically targets calcium and magnesium ions, but nitrate ions pass through unchanged. Phoenix residents with nitrate concerns need a reverse osmosis system at their drinking water tap in addition to whole-house water softening for hardness control.

4. Why Most Phoenix Homeowners Pick the Wrong Softener

Phoenix's extreme 12.3 GPG hardness level exposes every shortcut and compromise in water softener selection—mistakes that might go unnoticed in moderately hard water cities become expensive failures in the Sonoran Desert.

Mistake #1: Buying Based on Price Instead of Performance

An undersized water softener cannot handle Phoenix's continuous 12.3 GPG mineral assault. The same 24,000-grain capacity unit that serves a family well in a 4 GPG city like Portland will be overwhelmed within 48-72 hours in Phoenix. Resin exhaustion happens exponentially faster at higher hardness levels—while a moderately hard water city might allow 7-10 days between regeneration cycles, Phoenix homeowners with undersized units face daily regeneration or breakthrough hard water. This leads to constant salt refilling, skyrocketing water bills from frequent backwashing, and ultimately resin failure within 2-3 years instead of the expected 8-10 year lifespan.

Mistake #2: Confusing Softeners with Comprehensive Filtration

Water softeners use ion exchange resin to remove calcium and magnesium ions specifically. They do NOT reliably remove fluoride, chlorine, or nitrates from Phoenix's water supply. Phoenix residents dealing with both 12.3 GPG hardness and concerns about these additional contaminants need a two-stage approach: whole-house softening for mineral removal plus targeted filtration for specific contaminants. Expecting a softener alone to address Phoenix's complete water profile leads to disappointment and continued water quality issues.

Mistake #3: Ignoring Grain Capacity Mathematics

Phoenix homeowners must calculate grain capacity based on their actual hardness level, not generic estimates. The formula is: [Number of People] × 75 gallons/day × 12.3 GPG = daily grain demand. For a four-person Phoenix household: 4 × 75 × 12.3 = 2,460 grains consumed daily. Multiply by seven days = 17,220 grains per week. Add a 20% buffer for high-usage days = 20,664 grains minimum capacity needed. This calculation shows why Phoenix families need 32,000-grain capacity or higher—anything smaller forces inefficient daily regeneration.

Mistake #4: Overlooking Salt Efficiency at Extreme Hardness

At Phoenix's 12.3 GPG hardness, water softeners regenerate 2-3 times more frequently than in moderate hardness cities. An inefficient softener can consume 60-80 pounds of salt monthly versus 25-35 pounds for a high-efficiency model serving the same Phoenix household. Over a 10-year service life, this difference compounds to 4,000-5,400 pounds of extra salt—costing Phoenix homeowners an additional $800-1,200 in salt purchases alone, not counting the environmental impact of excess sodium discharge.

5. What to Do Next: Testing Your Phoenix Water

Before investing in any water treatment system, Phoenix homeowners should establish baseline measurements of their specific water quality. While citywide averages show 12.3 GPG hardness, individual neighborhoods can vary by 2-3 GPG depending on the blend of source waters serving that distribution zone.

Contact a local Phoenix water testing lab or purchase a comprehensive home test kit that measures hardness, fluoride, chlorine, and nitrates. Test water from both your kitchen cold tap and a hot water tap to identify any differences between incoming city water and water that has circulated through your home's plumbing system. Document these baseline numbers—you'll use them to verify your softener's performance after installation and during annual maintenance checks.

6. The SoftPro Elite HE: Built for Phoenix's Water

After evaluating Phoenix's water hardness of 12.3 GPG and the presence of fluoride, chlorine, and nitrates in the local supply, one system consistently rises to the top for Phoenix homeowners: the SoftPro Elite HE Water Softener.

Salt-Based Ion Exchange: The Only Technology That Works at 12.3 GPG

Salt-free "conditioner" systems do not actually remove hardness minerals—they only attempt to change crystal structure to reduce scale formation. At Phoenix's extreme 12.3 GPG level, salt-free technology simply cannot handle the mineral load. The SoftPro Elite HE uses true cation exchange resin that physically replaces calcium and magnesium ions with sodium ions. This is the only proven method for delivering genuinely soft water (under 1 GPG) when starting with Phoenix's mineral-dense supply.

Demand-Initiated Regeneration: Essential for Phoenix's Hardness Level

Traditional timer-based softeners regenerate on fixed schedules regardless of actual water usage or resin exhaustion. At 12.3 GPG, this leads to either hard water breakthrough (under-regeneration) or massive salt and water waste (over-regeneration). The SoftPro Elite HE monitors actual water flow and calculates real-time grain consumption, regenerating only when the resin bed approaches capacity. For Phoenix households consuming 2,400+ grains daily, this demand-based control prevents the hard water surprise mornings that plague Phoenix homes with inadequate systems.

NSF/ANSI Standard 44 Certified Performance

NSF certification verifies that the resin meets strict performance and materials safety standards under controlled testing conditions. For Phoenix residents already managing fluoride, chlorine, and nitrates in their water supply, knowing the softening process itself doesn't introduce additional contaminants is operationally critical. The certification also validates capacity claims—ensuring a 48,000-grain system actually delivers 48,000 grains of hardness removal before requiring regeneration.

Multiple Grain Capacity Options: Right-Sized for Phoenix Demand

The SoftPro Elite HE offers 32,000, 48,000, 64,000, and 80,000-grain capacity models. For most Phoenix households, the 48,000-grain model provides the optimal balance of capacity and efficiency. Using our four-person household example consuming 17,220 grains weekly, the 48K model allows comfortable 14-day regeneration cycles with room for high-usage periods like holidays or houseguests. Larger Phoenix families or homes with pools, spas, or extensive landscaping irrigation should consider the 64K or 80K models.

10-Year Warranty Protection

At Phoenix's 12.3 GPG hardness level, softener resin experiences heavy daily mineral loading that would stress inferior systems. The SoftPro's 10-year warranty provides Phoenix homeowners with protection during the years of highest hardness exposure. This warranty coverage acknowledges that extreme hardness cities like Phoenix demand more robust engineering and materials than moderate hardness markets.

High Salt Efficiency: Critical for Phoenix Operating Costs

The SoftPro Elite HE regenerates using 6-8 pounds of salt per cycle versus 12-15 pounds for standard efficiency models. At Phoenix's regeneration frequency, this efficiency difference saves 25-35 pounds of salt monthly—reducing annual salt costs by $180-250 while minimizing sodium discharge into Phoenix's wastewater system.

For Phoenix households dealing with 12.3 GPG of water hardness and the compounding presence of fluoride, chlorine, and nitrates, the SoftPro Elite HE is not a comfort upgrade—it is infrastructure protection for your home.

7. Homeowner Checklist: Preparing for Water Softener Installation

Phoenix homeowners should complete these preparation steps before scheduling softener installation to ensure smooth implementation and optimal performance.

□ Test current water hardness and document baseline numbers

□ Locate main water shutoff valve (required for installation)

□ Identify installation space near main water line with 110V electrical outlet

□ Verify adequate floor drain access within 20 feet for regeneration discharge

□ Check Phoenix municipal codes—most residential softener installations do not require permits, but verify with your specific HOA if applicable

□ Plan salt storage location away from direct sunlight and moisture

□ Schedule installation during moderate weather to minimize impact if water service is interrupted

8. How to Size Your Softener for Phoenix

Proper sizing calculations are critical for Phoenix's 12.3 GPG hardness—undersizing leads to constant regeneration and premature failure, while oversizing wastes money and floor space.

Step 1: Count household members (include regular overnight guests)

Step 2: Multiply by 75 gallons per person per day (Phoenix average)

Step 3: Multiply household gallons × 12.3 GPG = daily grain demand

Step 4: Multiply daily grains × 7 = weekly grain demand

Step 5: Add 20% buffer for high-usage days and seasonal variation

Step 6: Match result to SoftPro Elite HE capacity tier

Phoenix Four-Person Household Example:

4 people × 75 gallons = 300 gallons daily

300 gallons × 12.3 GPG = 3,690 grains daily

3,690 grains × 7 days = 25,830 grains weekly

25,830 + 20% buffer = 31,000 grains minimum capacity

Recommendation: 48,000-grain SoftPro Elite HE for optimal 10-14 day regeneration cycles

9. Installation in Phoenix: What to Know

Phoenix does not typically require licensed plumber installation for residential water softeners, but proper placement and connections are critical for optimal performance in the city's extreme hardness environment.

The SoftPro Elite HE installs on the main water line after the shutoff valve but before the water heater—this ensures all household water receives treatment while protecting the softener from potential backflow. Phoenix's typical municipal water pressure ranges from 45-65 PSI, which falls within the SoftPro's optimal operating range of 25-80 PSI.

Installation requires a drain connection within 20 feet for regeneration discharge. Phoenix homes typically use floor drains, utility sinks, or standpipes—the drain line cannot be directly connected to the sewer system per city codes. The regeneration process discharges 25-40 gallons of salt brine every 7-14 days, which poses no problems for Phoenix's wastewater treatment system.

Salt selection matters at Phoenix's 12.3 GPG consumption rate. Use only evaporated salt pellets—the highest purity option that minimizes brine tank residue and extends resin life. Avoid rock salt or solar crystals, which contain impurities that accumulate quickly at Phoenix's regeneration frequency. Plan to check salt levels monthly, as Phoenix households typically consume 40-60 pounds monthly.

10. Maintenance Schedule for Phoenix Homeowners

Phoenix's extreme 12.3 GPG hardness demands more frequent maintenance attention than moderate hardness cities—but following this schedule ensures optimal performance and maximum system lifespan.

Monthly Tasks:

Check salt level in brine tank—consumption is high at Phoenix's hardness level, typically requiring 40-60 pounds monthly for a four-person household. Inspect for salt bridges, which are crusty formations above the water line that prevent proper dissolution. Confirm the bypass valve remains in the "service" position unless you're performing maintenance.

Every 3 Months:

Clean the brine tank to prevent salt residue buildup that can clog injectors and reduce regeneration efficiency. Test post-softener water hardness with test strips—results should show under 1 GPG consistently. If hardness creeps above 1 GPG, investigate resin fouling, salt bridging, or capacity sizing issues.

Annual Maintenance:

Perform complete brine tank cleaning with removal of any accumulated sediment or salt residue. Conduct a full resin bed performance evaluation—if post-softener hardness exceeds 1 GPG despite proper salt levels and clean brine tank, the resin may need cleaning or replacement. Audit regeneration cycle timing and salt dosing to ensure settings remain optimal for your household's consumption patterns.

Every 5 Years:

Evaluate resin replacement needs. At Phoenix's 12.3 GPG hardness, resin beds work harder than in soft water cities and may require replacement every 8-10 years instead of the typical 10-15 year lifespan. Professional resin quality testing can determine remaining capacity and efficiency.

11. Recommended Setup for Phoenix Homes

Phoenix homeowners achieve optimal results by pairing the SoftPro Elite HE with targeted filtration for the city's additional contaminants.

Install the 48,000-grain SoftPro Elite HE as the primary whole-house system to address 12.3 GPG hardness. Add a point-of-use reverse osmosis system at the kitchen sink to remove fluoride and nitrates from drinking and cooking water. Install an activated carbon filter at the kitchen sink or whole-house to reduce chlorine taste and odor.

This three-stage approach addresses every aspect of Phoenix's water profile: hardness removal prevents scale damage throughout the home, while targeted filtration ensures optimal taste and quality at the tap for consumption.

12. Frequently Asked Questions for Phoenix Residents

13. Is Phoenix's water at 12.3 GPG dangerous to drink?

Phoenix's 12.3 GPG hardness level poses no direct health risks—the EPA classifies calcium and magnesium as beneficial minerals. The danger lies in infrastructure damage, appliance failure, and the cumulative cost of scale buildup throughout your home's plumbing system. Some studies suggest extremely hard water may contribute to kidney stone formation in susceptible individuals, but the primary concern for Phoenix residents is property damage rather than immediate health effects.

14. Will a water softener remove fluoride, chlorine, and nitrates from Phoenix water?

The SoftPro Elite HE water softener removes calcium and magnesium (hardness) but does NOT remove fluoride, chlorine, or nitrates. These contaminants require different treatment technologies: reverse osmosis for fluoride and nitrates, activated carbon for chlorine. Phoenix residents concerned about these additional contaminants should install targeted point-of-use filters alongside their whole-house softener.

15. How much salt will I use per month in Phoenix at 12.3 GPG?

A typical four-person Phoenix household consumes 40-60 pounds of salt monthly with a properly sized SoftPro Elite HE system. This calculation assumes 300 gallons daily water usage × 12.3 GPG × 30 days = 110,700 grains monthly. At 6-8 pounds salt per regeneration cycle, expect 12-15 regeneration cycles monthly. Higher efficiency models use less salt per cycle, reducing monthly consumption to the lower end of this range.

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

Phoenix does not require permits for standard residential water softener installations. However, check with your specific homeowners association if you live in a planned community—some HOAs have architectural review requirements for exterior utility installations. The installation must comply with Phoenix plumbing codes regarding drain connections and backflow prevention, but these are standard requirements that qualified installers handle routinely.

17. Why does soft water feel slippery in the shower after installing a softener?

The "slippery" feeling is actually your skin's natural oils and moisture that were previously stripped away by Phoenix's 12.3 GPG hard water. Calcium and magnesium ions bond with soap to form insoluble scum that coats skin and prevents effective cleansing. With soft water, soap creates true lather that rinses clean, leaving your skin's natural protective barrier intact. Most Phoenix residents adjust to this improved skin feel within 2-3 weeks.

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

Phoenix homeowners notice immediate improvements in soap lather and reduced spotting on dishes and glassware within 24-48 hours. Skin and hair improvements appear within 1-2 weeks as natural oils are restored. Appliance protection begins immediately, but reversing existing scale damage takes months. Energy efficiency improvements from descaled water heater elements become apparent on utility bills within 30-60 days.

19. Can the SoftPro Elite HE handle Phoenix's water without separate filtration?

The SoftPro Elite HE effectively addresses Phoenix's 12.3 GPG hardness but does not remove fluoride, chlorine taste/odor, or nitrates. For comprehensive water treatment, Phoenix residents should pair the softener with point-of-use reverse osmosis for drinking water and activated carbon filtration for chlorine removal. The softener alone prevents scale damage and improves soap performance—additional filtration enhances taste and addresses specific contaminant concerns.

20. 30-Day Action Plan for Phoenix Homeowners

Week 1: Test your current water hardness and document baseline measurements. Research SoftPro Elite HE pricing and available grain capacities for your household size.

Week 2: Calculate your specific grain capacity needs using Phoenix's 12.3 GPG. Identify installation location and verify electrical and drain requirements.

Week 3: Schedule installation with a qualified local installer. Purchase initial salt supply (evaporated pellets only).

Week 4: Complete installation and initial setup. Test post-softener water hardness to confirm under 1 GPG performance.

21. Final Verdict for Phoenix

Phoenix's water hardness of 12.3 GPG demands commercial-grade treatment in a residential package. The city's extremely hard water classification, combined with fluoride, chlorine, and nitrates, creates a challenging environment that exposes every weakness in inferior water treatment systems.

The SoftPro Elite HE rises above the competition through three critical advantages specifically matched to Phoenix conditions: its demand-initiated regeneration prevents the hard water breakthrough that plagues Phoenix homes with timer-based systems, its high grain capacity options (48K-80K) provide adequate reserves for 12.3 GPG daily consumption, and its certified salt efficiency reduces operating costs during the frequent regeneration cycles Phoenix's hardness level demands.

For Phoenix homeowners, water softening isn't a luxury upgrade—it's infrastructure insurance against scale damage that costs Valley residents thousands annually in premature appliance replacement and energy waste. Check current SoftPro Elite HE pricing and available grain capacities for Phoenix households, and consider scheduling a professional water analysis to establish baseline hardness measurements before installation.

In a city where Camelback Mountain's red sandstone reminds us daily of water's power to shape landscapes over time, Phoenix homeowners can't afford to let that same mineral-laden water reshape their plumbing systems and drain their bank accounts.
