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

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Phoenix, AZ

Every summer morning in Phoenix, thousands of homeowners step into their showers and unknowingly bathe in water harder than concrete mix. At 12.3 grains per gallon (GPG), Phoenix's municipal water supply ranks among the hardest in the United States — a hidden household destroyer that costs Valley residents millions in premature appliance failures, sky-high utility bills, and endless plumbing repairs.

To understand what 12.3 GPG means for your home, imagine your water as liquid sandpaper. Each grain per gallon represents 17.1 milligrams of dissolved calcium and magnesium minerals per liter of water. At Phoenix's 12.3 GPG level, every gallon flowing through your pipes carries over 1,400 milligrams of rock-hard minerals — enough to coat heating elements, clog spray nozzles, and gradually strangle your plumbing from the inside out.

Phoenix draws its water primarily from the Colorado River via the Central Arizona Project canal, plus groundwater from deep desert aquifers. Both sources flow through limestone and gypsum formations for hundreds of miles, dissolving massive quantities of calcium and magnesium along the way. By the time this water reaches Phoenix taps, it's classified as "extremely hard" — the highest category on the hardness scale.

For Phoenix homeowners, 12.3 GPG isn't just a water quality statistic — it's a monthly tax on every appliance, every shower, every load of laundry. The average Phoenix household loses $1,200 annually to hard water damage: shortened appliance lifespans, 30-40% higher energy bills, and triple the soap and detergent costs. Your home's value depends on functional systems, and extremely hard water systematically destroys them all.

2. What 12.3 GPG Does to Your Home

At 12.3 GPG, calcium carbonate doesn't just coat your water heater — it forms armor-thick deposits that can reduce efficiency by 30-40% within 18 months. The mineral crystallization happens fastest on heated surfaces, where dissolved calcium and magnesium precipitate into rock-hard scale. A standard 40-gallon electric water heater in Phoenix consumes an extra $300-500 annually in electricity once scale accumulates on the heating elements.

Phoenix's extremely hard water creates a compounding destruction cycle throughout your home's plumbing system. Inside copper and PEX pipes, scale forms concentric rings that gradually narrow the interior diameter. At 12.3 GPG, measurable flow restriction begins within 3-4 years in frequently used lines. Older galvanized steel pipes — common in Phoenix homes built before 1980 — can lose 50% of their interior diameter within a decade of 12.3 GPG exposure.

Your major appliances face an uphill battle against Phoenix's mineral-loaded water. Dishwashers typically last 6-7 years with soft water, but only 4-5 years at 12.3 GPG hardness. The spray arms clog with calcium deposits, the heating element scales over, and the interior glass develops permanent white etching that no amount of cleaning can remove. Washing machines suffer similar fates — the mineral buildup damages pumps, clogs valves, and leaves a chalky residue on every fabric fiber.

The soap and detergent waste at 12.3 GPG reaches staggering proportions for Phoenix families. Calcium and magnesium ions chemically bind with soap molecules, forming insoluble precipitates instead of cleaning lather. A Phoenix household uses 3-4 times more laundry detergent, dish soap, and shampoo than families in soft-water cities. Over a year, this "soap tax" costs the average Phoenix family $400-600 in extra cleaning products.

Phoenix residents also endure the physical effects of extremely hard water daily. At 12.3 GPG, calcium ions strip natural oils from skin and form mineral deposits on hair shafts, leaving both dry, brittle, and irritated. Children with eczema and sensitive skin conditions show measurable improvement when switching to soft water. The "slippery" feeling of soft water isn't actually slippery — it's simply the absence of mineral film coating your skin.

Laundry emerges from Phoenix washing machines gray, stiff, and scratchy regardless of detergent quality. The calcium and magnesium deposits become permanently embedded in fabric fibers, creating a sandpaper texture that shortens clothing life by 30-40%. White fabrics develop an unmistakable dingy cast, and colored fabrics fade faster as mineral deposits interfere with dye molecules.

The annual "hard water tax" for Phoenix households at 12.3 GPG totals approximately $1,800-2,400 per year: $500 in extra energy costs, $450 in additional soap and detergent, $600 in accelerated appliance replacement, and $400 in plumbing repairs and maintenance. Over a decade, extremely hard water costs Phoenix homeowners $18,000-24,000 in preventable expenses.

3. Phoenix's Specific Contaminant Profile

Beyond the crushing 12.3 GPG hardness baseline, Phoenix residents are also contending with chloramine and fluoride — each of which interacts with water hardness in its own destructive way. Understanding these contaminants is essential for Phoenix homeowners because the combination creates layered challenges that hardness alone doesn't address.

Chloramine in Phoenix Water

Phoenix Water Services switched from chlorine to chloramine disinfection in 2007, and the change brought both benefits and complications for residents. Chloramine is a more stable disinfectant than chlorine — it maintains effectiveness throughout the distribution system without forming as many cancer-linked trihalomethanes (THMs). However, chloramine is also significantly harder to remove from water and creates its own set of household problems.

At 12.3 GPG hardness, chloramine interacts with calcium and magnesium deposits to accelerate corrosion of rubber gaskets, seals, and O-rings throughout your plumbing system. The combination of extremely hard water and chloramine reduces the lifespan of toilet flappers, faucet cartridges, and appliance hoses by 40-60% compared to soft, chlorine-treated water. Phoenix residents notice a distinctive "medicinal" or "band-aid" odor from their tap water — that's chloramine's signature smell.

The EPA maximum residual disinfectant level for chloramine is 4.0 mg/L, and Phoenix typically maintains levels between 1.5-3.0 mg/L — well within regulatory limits but strong enough to affect taste, odor, and household systems. Chloramine is toxic to fish, amphibians, and dialysis patients, requiring special filtration for aquariums and medical equipment. Unlike chlorine, which dissipates when water sits in an open container, chloramine remains active for days.

A standard water softener like the SoftPro Elite HE does not remove chloramine. Phoenix residents seeking chloramine reduction need a catalytic carbon whole-house filter installed upstream of their softener. Standard activated carbon is ineffective against chloramine — only catalytic carbon or specialized chloramine-removal media can break the chlorine-ammonia bond.

Fluoride in Phoenix Water

Phoenix adds fluoride to its water supply at the EPA-recommended 0.7 mg/L for dental health benefits. The fluoride compound used is typically fluorosilicic acid, added at the water treatment plants before distribution. This intentional addition means every Phoenix tap consistently delivers fluoride at therapeutic levels.

Fluoride doesn't directly interact with the 12.3 GPG hardness, but many Phoenix residents have concerns about long-term consumption and seek removal options. The EPA maximum contaminant level for fluoride is 4.0 mg/L for health protection and 2.0 mg/L for aesthetic concerns (dental fluorosis prevention). Phoenix's 0.7 mg/L level is well below both thresholds and matches current CDC recommendations for community water fluoridation.

Water softeners, including the SoftPro Elite HE, do not remove fluoride from water. The ion exchange process targets calcium and magnesium specifically — fluoride ions pass through unchanged. Phoenix residents who want fluoride reduction for drinking and cooking water should consider a reverse osmosis system at the kitchen tap in addition to whole-house softening.

The combination of extremely hard water at 12.3 GPG plus chloramine and fluoride presents a three-pronged challenge: mineral scale destruction, accelerated corrosion from chloramine, and potential concerns about long-term fluoride exposure. A comprehensive Phoenix water treatment approach addresses hardness first with the SoftPro Elite HE, then adds specialized filters for chloramine and fluoride removal as needed.

4. Why Most Phoenix Homeowners Pick the Wrong Softener

Walk into any Phoenix home improvement store, and you'll find water softeners marketed with generic sizing charts that assume 3-5 GPG hardness — completely inadequate for Phoenix's 12.3 GPG reality. After fifteen years covering water treatment failures across the Valley, I've identified four critical mistakes that leave Phoenix homeowners with expensive equipment that can't handle their water.

Mistake #1: Buying on Price Alone

A $400 big-box softener that works adequately in Tucson's 7 GPG water will fail catastrophically in Phoenix within weeks. At 12.3 GPG, the resin bed exhausts 75% faster than manufacturer calculations based on "average" hardness. An undersized 24,000-grain unit designed for moderate hardness cannot regenerate frequently enough to prevent hard water breakthrough in Phoenix homes.

The false economy becomes obvious quickly: homeowners spend $400 on an inadequate system, then $200 more on extra salt, $300 on a service call when it stops working, and finally $800 on a proper replacement. Phoenix's extreme hardness demands commercial-grade grain capacity from day one.

Mistake #2: Confusing Softeners with Filters

Water softeners remove calcium and magnesium through ion exchange — they are not water filters. Phoenix residents dealing with chloramine odor and taste often assume a softener will address these issues. It won't. The SoftPro Elite HE will deliver genuinely soft water at 0-1 GPG, eliminating scale and soap scum, but chloramine and fluoride require separate treatment technologies.

Phoenix homeowners need to understand the treatment sequence: softening first to protect downstream equipment from scale, then specialized filtration for taste, odor, and specific contaminants. Expecting one system to solve multiple water chemistry problems leads to disappointment and wasted money.

Mistake #3: Ignoring Grain Capacity Math

Most Phoenix homeowners have never calculated their actual daily grain demand, leading to chronic under-sizing. The formula is straightforward:

[People] × 75 gallons/day × 12.3 GPG = daily grain demand

For a 4-person Phoenix household:
4 people × 75 gallons × 12.3 GPG = 2,460 grains per day

Over a week, that's 17,220 grains. A 24,000-grain system would regenerate every 4-5 days under this load — acceptable but not optimal. A 32,000-grain system provides the 6-7 day regeneration cycle that maximizes efficiency and resin life in Phoenix's demanding conditions.

Mistake #4: Overlooking Salt Efficiency

At 12.3 GPG, a Phoenix softener regenerates 2-3 times more frequently than systems in moderate hardness cities. An inefficient softener using 15 pounds of salt per regeneration costs $300-400 annually in salt alone. High-efficiency models like the SoftPro Elite HE use 6-8 pounds per cycle — saving Phoenix households $150-200 yearly in salt costs.

Over the system's 10-year lifespan, salt efficiency becomes a $1,500-2,000 difference. In Phoenix's extreme hardness environment, efficiency isn't a luxury feature — it's an operational necessity.

What to Do Next

Before shopping for any water softener in Phoenix, test your home's actual water hardness and flow rate. Purchase a TDS meter and hardness test strips to establish baseline measurements. Check your water pressure at multiple fixtures — the SoftPro Elite HE requires 20-80 PSI to function properly. Locate your main water shutoff valve and measure the available space for system installation. Document any existing water treatment equipment and note the age of your water heater and major appliances for insurance purposes.

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

After evaluating Phoenix's water hardness of 12.3 GPG and the presence of chloramine and fluoride in the local supply, one system consistently rises to the top for Phoenix homeowners: the SoftPro Elite HE Water Softener. This isn't marketing hyperbole — it's the logical conclusion after analyzing every challenge Phoenix water presents.

Salt-Based Ion Exchange for Extreme Hardness

Salt-free "conditioner" systems marketed in Phoenix are fundamentally inadequate for 12.3 GPG hardness. These systems attempt to change calcium carbonate crystal structure through template-assisted crystallization (TAC) or electromagnetic fields, but they don't actually remove hardness minerals from water. At Phoenix's extreme hardness levels, salt-free systems cannot prevent scale formation on heating elements or eliminate soap scum.

The SoftPro Elite HE uses proven cation exchange resin to physically replace calcium and magnesium ions with sodium ions. This is the only technology that delivers genuinely soft water (0-1 GPG) from Phoenix's 12.3 GPG source. The resin bed captures hardness minerals and releases them during regeneration — true removal, not temporary restructuring.

Demand-Initiated Regeneration (DIR) Technology

At 12.3 GPG, resin beds exhaust faster than manufacturer estimates based on national averages. Traditional time-clock regeneration systems either waste salt and water by regenerating too frequently, or allow hard water breakthrough by regenerating too rarely. Phoenix's extreme hardness makes this balancing act nearly impossible with fixed scheduling.

The SoftPro Elite HE's DIR system monitors actual water usage and resin capacity, regenerating only when the bed is truly exhausted. For Phoenix households consuming 2,400+ grains daily, DIR prevents the hard water breakthrough that damages appliances while avoiding the salt waste that inflates operating costs.

NSF/ANSI Standard 44 Certified Resin

NSF certification verifies that resin meets strict performance standards and doesn't leach contaminants into treated water. For Phoenix residents already managing chloramine and fluoride in their water supply, knowing the softening process itself introduces no additional chemicals or contaminants provides essential peace of mind.

Certified resin also performs more predictably under Phoenix's demanding conditions. The beads maintain their ion exchange capacity longer and resist degradation from frequent regeneration cycles required at 12.3 GPG hardness.

Multiple Grain Capacity Options

The SoftPro Elite HE is available in 32,000, 48,000, 64,000, and 80,000 grain capacities — essential flexibility for right-sizing systems to Phoenix households. A 2-person Phoenix household needs different capacity than a 6-person family, but both need commercial-grade performance to handle 12.3 GPG water.

For a typical 4-person Phoenix household using 300 gallons daily at 12.3 GPG hardness:
4 × 75 gallons × 12.3 GPG = 2,460 grains daily
Weekly demand: 17,220 grains
Recommended capacity: 48,000 grains (7-day regeneration cycle)

10-Year Comprehensive Warranty

At 12.3 GPG, softener components face accelerated wear from constant heavy-duty operation. The SoftPro's 10-year warranty covers resin replacement, control valve repairs, and tank integrity — protection during the years of highest stress in Phoenix's extreme hardness environment.

Most budget softeners offer 1-3 year warranties because manufacturers know the systems won't survive Phoenix conditions long-term. SoftPro's decade-long coverage demonstrates confidence in the system's ability to handle extreme hardness day after day.

Chloramine Compatibility

The SoftPro Elite HE's resin and control components are designed to withstand chloramine exposure without degradation. While the system doesn't remove chloramine from water, it continues operating effectively in Phoenix's chloramine-treated supply without component failures or performance loss.

Phoenix homeowners who want chloramine removal can install a catalytic carbon pre-filter upstream of the SoftPro without voiding the warranty. This modular approach allows customized treatment while maintaining system integrity.

For Phoenix households dealing with 12.3 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.

Homeowner Checklist

Before purchasing any water softener for Phoenix conditions, verify these four requirements are met: Confirm your home's water pressure falls between 20-80 PSI using a pressure gauge. Measure available space near your main water line — you need 4 feet of clearance for service access. Locate a drain within 20 feet for regeneration discharge. Test your current water hardness with TDS strips to confirm it matches Phoenix's typical 12.3 GPG range. Document your household size and water usage patterns to ensure proper grain capacity selection.

6. How to Size Your Softener for Phoenix

Proper sizing for Phoenix's 12.3 GPG water requires precise calculation — guessing leads to system failure or massive salt waste. Follow this step-by-step formula to determine your household's exact grain capacity needs:

Step 1: Count household members (include frequent guests or family members who visit regularly)

Step 2: Multiply by 75 gallons per person per day (Phoenix average including all uses: drinking, cooking, bathing, laundry, dishwashing)

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

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

Step 5: Add 20% buffer for high-usage days (pool filling, guests, extra laundry)

Step 6: Match total to SoftPro Elite HE grain tier

Example calculation for a 4-person Phoenix household:
Step 1: 4 people
Step 2: 4 × 75 = 300 gallons daily
Step 3: 300 × 12.3 GPG = 3,690 grains daily
Step 4: 3,690 × 7 = 25,830 grains weekly
Step 5: 25,830 × 1.20 = 31,000 grains with buffer
Step 6: Select 48,000-grain SoftPro Elite HE

The 48,000-grain capacity provides a 6-7 day regeneration cycle, which maximizes salt efficiency and resin life under Phoenix conditions. Regenerating every 5-7 days is optimal — more frequent cycles waste salt and water, while less frequent regeneration risks hard water breakthrough during peak usage.

Phoenix households with swimming pools, large gardens, or home businesses should consider the 64,000-grain model to accommodate irregular high-usage periods. The extra capacity costs less upfront than dealing with hard water damage during busy periods.

7. Installation in Phoenix: What to Know

Arizona does not require licensed plumber installation for residential water softeners, but Phoenix's extreme hardness makes professional installation worth considering. The system must be placed after your main shutoff valve but before the water heater to protect all downstream appliances and fixtures.

Phoenix homes typically have water pressure between 40-60 PSI, which falls perfectly within the SoftPro Elite HE's operating range of 20-80 PSI. The installation requires a drain line for regeneration discharge — most Phoenix homes can use a laundry drain, floor drain, or exterior drainage area. The discharge contains salt brine, so avoid directing it toward landscaping or pool equipment.

Salt selection is critical at Phoenix's 12.3 GPG hardness level. Use only evaporated salt pellets — the highest purity option that leaves minimal residue in the brine tank. Solar salt crystals and rock salt contain impurities that accumulate faster at high regeneration frequencies, creating maintenance headaches and reducing system efficiency.

Location matters in Phoenix's climate. Install the system in a shaded area if possible — direct sun exposure can degrade plastic components over time. Garage installations work well, but ensure adequate ventilation around the control head for heat dissipation during Arizona summers.

At 12.3 GPG consumption rates, check salt levels monthly during winter and bi-weekly during summer when water usage peaks. The brine tank should maintain salt levels 3-4 inches above the water line to ensure proper regeneration. Phoenix's low humidity helps prevent salt bridging, but regular monitoring prevents service interruptions.

8. Maintenance Schedule for Phoenix Homeowners

Phoenix's 12.3 GPG hardness accelerates wear on all water treatment components, making preventive maintenance essential for long-term performance. Follow this schedule to maximize your SoftPro Elite HE's lifespan and efficiency:

Monthly Tasks

Check salt levels in the brine tank — consumption is high at 12.3 GPG. Phoenix households typically use 40-60 pounds of salt monthly, depending on family size and water usage. Look for salt bridges (hard crust above the water line) that can prevent proper regeneration. Verify the bypass valve remains in service position — accidental switching to bypass allows hard water throughout your home.

Every 3 Months

Clean the brine tank to remove accumulated sediment and maintain peak performance. Test post-softener water hardness with test strips — readings should stay under 1 GPG consistently. If hardness creeps above 1 GPG, investigate resin fouling or system malfunction immediately. Inspect all connections for mineral buildup or corrosion, especially common in Phoenix's challenging water conditions.

Annual Maintenance

Perform complete brine tank cleaning with warm water and mild detergent. Check resin bed performance by testing hardness at multiple taps throughout your home. At 12.3 GPG input hardness, any post-softener reading above 1 GPG indicates resin degradation or system problems requiring professional attention.

Audit regeneration cycles to confirm timing and salt dosage remain optimal for your household's current usage patterns. Phoenix families often see usage changes as children grow or family size changes — adjust settings accordingly.

Every 5 Years

Evaluate resin replacement needs — Phoenix's extreme hardness degrades resin faster than soft-water cities. Professional resin inspection can identify early signs of fouling or capacity loss before complete system failure. Consider upgrading to higher-capacity resin if household water usage has increased significantly.

Phoenix residents should establish baseline hardness readings before installation and retest 30 days after to confirm the system performs as expected. Keep records of salt usage, regeneration frequency, and any maintenance performed — this data helps identify problems early and maintains warranty coverage.

Recommended Setup for Phoenix

The optimal Phoenix water treatment configuration combines the SoftPro Elite HE with targeted pre-filtration for maximum protection and performance. Install a 5-micron sediment pre-filter before the softener to capture particulates from aging distribution pipes. Add a catalytic carbon filter upstream if chloramine taste and odor concerns exist. Position the SoftPro Elite HE last in the sequence to deliver soft water throughout your home while protecting the resin from fouling. Consider point-of-use reverse osmosis at the kitchen sink for fluoride removal if desired. This modular approach addresses Phoenix's complex water chemistry systematically.

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

Phoenix's 12.3 GPG hardness poses no direct health risks — calcium and magnesium are essential minerals that some nutritionists actually recommend. The EPA has no maximum contaminant level for hardness because it's not considered harmful to human health. However, the mineral load creates serious problems for plumbing, appliances, and household comfort that justify treatment.

10. Will a water softener remove chloramine and fluoride from Phoenix water?

No, the SoftPro Elite HE removes only calcium and magnesium through ion exchange — chloramine and fluoride pass through unchanged. Phoenix residents seeking chloramine removal need a catalytic carbon filter installed before the softener. For fluoride reduction, a reverse osmosis system at the drinking water tap is the most effective option. Water softening and contaminant filtration are separate processes requiring different technologies.

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

A typical Phoenix household consumes 40-80 pounds of salt monthly, depending on family size and water usage. At 12.3 GPG, a 4-person family using 300 gallons daily will regenerate every 6-7 days, using approximately 8-10 pounds of salt per cycle. Annual salt costs range from $60-120 for evaporated pellets — a small price compared to the $1,800+ annual cost of untreated hard water damage.

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

Phoenix does not require permits for residential water softener installation, and Arizona has no statewide licensing requirements for this work. Homeowners can legally install their own systems or hire any qualified contractor. However, installation must comply with local plumbing codes, particularly regarding drain connections and backflow prevention. Check with your HOA if applicable — some communities have restrictions on water treatment equipment placement.

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

Soft water feels slippery because you're experiencing the absence of mineral film coating your skin for the first time. Phoenix's 12.3 GPG water leaves calcium and magnesium deposits that create an artificial "grip" sensation. Soft water allows soap to lather properly and rinse completely clean, leaving skin naturally smooth rather than coated with mineral residue. Most Phoenix residents adjust to the sensation within 2-3 weeks and prefer it long-term.

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

Phoenix homeowners notice immediate changes in soap lather and shower feel within 24 hours of SoftPro Elite HE installation. White spotting on dishes and fixtures stops appearing within the first week. Existing scale deposits take 2-6 months to dissolve gradually — don't expect overnight removal of years of 12.3 GPG buildup. Appliance efficiency improvements become measurable after 3-6 months as heating elements operate scale-free.

15. Can the SoftPro Elite HE handle Phoenix's water without a separate filter?

Yes, the SoftPro Elite HE effectively softens Phoenix's 12.3 GPG water without additional equipment — that's its primary function. However, Phoenix residents concerned about chloramine taste and odor will want a catalytic carbon pre-filter. Those seeking fluoride removal need point-of-use reverse osmosis. The SoftPro handles hardness completely; other contaminants require specialized treatment if desired.

16. What's the difference between water softening and water filtering in Phoenix?

Water softening removes calcium and magnesium minerals through ion exchange, while filtering removes different contaminants through various media. Phoenix's SoftPro Elite HE addresses the 12.3 GPG hardness that damages appliances and creates scale. Filters address taste, odor, chloramine, and other specific concerns. Most Phoenix homes benefit from softening first to protect equipment, then filtering for drinking water quality if desired.

30-Day Action Plan

Week 1: Test your current water hardness and pressure, research SoftPro Elite HE grain capacities for your household size. Week 2: Get installation quotes from qualified contractors, verify drain access and electrical requirements. Week 3: Purchase your system and schedule installation, order appropriate salt pellets for startup. Week 4: Complete installation, test system performance, establish baseline soft water readings throughout your home. Document everything for warranty purposes and future reference.

17. Final Verdict for Phoenix

Phoenix's water hardness of 12.3 GPG demands commercial-grade treatment — this isn't a situation where "good enough" equipment survives long-term. The combination of extreme mineral content plus chloramine creates an aggressive environment that destroys budget softeners and inadequately sized systems within months.

The SoftPro Elite HE rises above other options specifically because of its demand-initiated regeneration system, multiple grain capacities for precise sizing, and proven durability under extreme hardness conditions. Phoenix households need the 48,000 or 64,000-grain models to handle 12.3 GPG water efficiently — smaller systems are false economy that leads to frequent failures.

For Phoenix residents tired of replacing water heaters every 4-5 years, buying soap by the case, and dealing with brittle hair and scratchy laundry, the SoftPro Elite HE represents infrastructure protection rather than luxury upgrade. The system pays for itself within 18-24 months through reduced energy bills, soap savings, and appliance protection alone.

Check current SoftPro Elite HE pricing and available grain capacities for Phoenix households at authorized dealers. The investment in proper water treatment today prevents the $18,000-24,000 in hard water damage that Phoenix homeowners typically face over a decade — money that's better spent enjoying the Valley's year-round sunshine instead of replacing destroyed appliances.
