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

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Tucson, Arizona

Every month, Tucson homeowners are unknowingly writing a check for $180 to $250 in preventable damage costs. This "hard water tax" stems directly from Tucson's municipal water supply measuring 12.8 grains per gallon (GPG) — classified as extremely hard water. To put this in perspective, imagine your home's plumbing system as a network of arteries, and the 12.8 GPG hardness as cholesterol slowly building dangerous blockages throughout every pipe, fixture, and appliance.

Tucson draws its water primarily from the Colorado River via the Central Arizona Project canal, supplemented by groundwater from the Tucson Basin aquifer. Both sources carry dissolved limestone and gypsum deposits picked up during the journey through Arizona's mineral-rich geology. When this water enters Tucson homes at 12.8 GPG, it carries enough calcium and magnesium to deposit nearly a pound of rock-hard scale inside a standard 40-gallon water heater within 18 months.

The 12.8 GPG measurement means that every gallon of Tucson water contains 12.8 grains of dissolved calcium and magnesium minerals. For context, water below 3.5 GPG is considered soft, while anything above 10.5 GPG falls into the "extremely hard" category. At 12.8 GPG, Tucson's water hardness ranks in the top 15% most problematic levels in the United States.

For Tucson families, this extreme hardness translates into measurable financial consequences. Water heaters lose 35-45% efficiency within two years. Dishwashers and washing machines fail 3-4 years earlier than their expected lifespan. Soap and detergent consumption doubles or triples as calcium ions prevent proper lathering. Meanwhile, the constant mineral buildup etches permanent damage into glassware, creates grey residue on clothing, and leaves skin feeling tight and itchy after every shower.

2. What 12.8 GPG Does to Your Tucson Home

At Tucson's 12.8 GPG hardness level, calcium carbonate scale forms aggressively on every heated surface in your plumbing system. Inside your water heater, these minerals create a concrete-like coating on heating elements that forces the unit to work 40-50% harder to achieve the same temperature. Within 24 months, a typical Tucson water heater operating with untreated 12.8 GPG water experiences efficiency losses equivalent to adding $35-50 per month to your utility bill.

The scale formation process accelerates exponentially at 12.8 GPG because mineral saturation reaches critical levels. When water temperatures exceed 140°F — standard for most Tucson water heaters — calcium and magnesium ions rapidly precipitate out of solution and bond permanently to metal surfaces. This process, called calcite crystallization, creates concentric rings of mineral buildup that narrow pipe interiors by 15-25% within five years in older Tucson homes with galvanized steel plumbing.

Tucson's 12.8 GPG hardness reduces major appliance lifespans by devastating margins. Dishwashers typically last 6-7 years instead of the expected 10-12 years. Washing machines experience pump failures and valve blockages after 8-9 years rather than 12-15 years. Coffee makers, ice makers, and tankless water heaters are particularly vulnerable — many manufacturers void warranties entirely when hardness exceeds 7 GPG without a water softener, making Tucson's 12.8 GPG nearly twice the warranty threshold.

The soap waste at 12.8 GPG creates a measurable household budget drain. Calcium and magnesium ions chemically react with soap molecules to form insoluble curds rather than cleansing lather. A typical Tucson family uses 3-4 times more laundry detergent, dish soap, shampoo, and body wash compared to soft water areas. This compounds into approximately $180-220 annually in excess soap and cleaning product costs for a four-person household.

Personal care impacts become severe at Tucson's 12.8 GPG level. Calcium ions strip natural oils from skin and hair, leaving a residual mineral film that prevents moisture retention. Dermatologists in Arizona report significantly higher rates of eczema, dry skin conditions, and scalp irritation in hard water areas. Hair becomes brittle, dull, and difficult to manage as mineral deposits coat each strand and prevent conditioning agents from penetrating.

Laundry and household surfaces bear visible damage from 12.8 GPG exposure. Clothing emerges from washing machines grey, stiff, and scratchy as mineral deposits embed between fabric fibers. White garments develop permanent yellowing that no amount of bleach can reverse. Glassware develops irreversible etching — a frosted, cloudy appearance caused by alkaline minerals literally eating into the glass surface. Shower doors, faucets, and fixtures accumulate thick, chalky deposits that require aggressive scrubbing and specialized cleaners.

The annual "hard water tax" for a Tucson household at 12.8 GPG totals approximately $2,100-2,800. This calculation includes accelerated appliance replacement costs ($800-1,200), increased energy consumption ($420-600), excess soap and cleaning products ($180-220), potential plumbing repairs ($300-500), and professional cleaning services or specialized products to combat mineral buildup ($400-680). Over a decade, this compounds to $21,000-28,000 in preventable costs.

3. Tucson's Specific Contaminant Profile

Tucson's water supply presents a complex challenge beyond the baseline 12.8 GPG hardness: residents are simultaneously managing fluoride, chlorine, arsenic, and nitrates — each interacting with the extreme mineral content in distinct ways.

Fluoride in Tucson's Water System

Tucson Water adds fluoride to the municipal supply at approximately 0.7 mg/L as part of the Centers for Disease Control's dental health initiative. This fluoride enters the system as fluorosilicic acid during the treatment process at Tucson's water treatment facilities. At 12.8 GPG hardness, calcium ions can form calcium fluoride complexes that alter the taste profile, creating a slightly bitter or metallic flavor that some Tucson residents notice, particularly in coffee and tea.

The interaction between fluoride and Tucson's extreme hardness creates aesthetic concerns rather than health risks. EPA's maximum contaminant level for fluoride is 4.0 mg/L for health effects and 2.0 mg/L for secondary aesthetic standards. Tucson's levels remain well within safe parameters. However, residents concerned about fluoride intake should understand that water softeners do NOT remove fluoride — the ion exchange process targets calcium and magnesium specifically, leaving fluoride ions unchanged.

Chlorine Treatment in Tucson's Distribution System

Tucson Water utilizes chlorine as the primary disinfectant throughout its distribution network, with residual levels typically ranging from 1.0-3.0 mg/L to ensure bacterial safety during transport. The chlorine originates from sodium hypochlorite injection at treatment plants and booster stations. In Tucson's desert climate, chlorine concentrations often increase during summer months when higher temperatures accelerate bacterial growth risks, leading to stronger taste and odor complaints from residents.

Chlorine becomes more problematic in the presence of 12.8 GPG hardness because scale deposits harbor chlorine and create concentrated pockets of oxidizing chemicals. This accelerates the degradation of rubber gaskets, O-rings, and seals throughout plumbing systems. Chlorine also forms disinfection byproducts (trihalomethanes and haloacetic acids) when it reacts with organic matter in the distribution pipes — compounds that can contribute to the chemical taste many Tucson residents report.

While the SoftPro Elite HE effectively removes hardness minerals, chlorine requires separate treatment through activated carbon filtration. A whole-house carbon filter installed upstream of the softener protects the ion exchange resin from chlorine damage while eliminating taste and odor issues for Tucson households.

Arsenic in Tucson's Groundwater Sources

Arsenic occurs naturally in Tucson's groundwater at levels typically ranging from 2-8 parts per billion (ppb), originating from volcanic rock formations and mining activities in Arizona's geological history. The Tucson Basin aquifer contains arsenic-bearing minerals that slowly dissolve into groundwater over decades. While these levels remain below EPA's maximum contaminant level of 10 ppb, long-term exposure to arsenic at any detectable level warrants consideration for sensitive populations.

Arsenic presents a unique challenge because water softeners do NOT remove this contaminant. The ion exchange resin in the SoftPro Elite HE targets divalent cations (calcium and magnesium) while arsenic typically exists as arsenate or arsenite — anionic compounds that pass through softener resin unchanged. Tucson residents concerned about arsenic reduction should install a reverse osmosis system at their kitchen tap for drinking and cooking water, independent of their whole-house softener.

The combination of arsenic and 12.8 GPG hardness requires a strategic two-stage approach. Hard water damages reverse osmosis membranes rapidly, reducing their arsenic removal effectiveness and shortening replacement intervals from 2-3 years down to 6-12 months. Installing the SoftPro Elite HE first protects downstream RO equipment while ensuring comprehensive water treatment for Tucson households.

Nitrates from Agricultural and Development Sources

Nitrate contamination in Tucson's water supply stems from decades of agricultural runoff from surrounding farming areas and septic system leaching in rapidly developed suburban areas. Levels typically measure 2-6 mg/L, well below EPA's maximum contaminant level of 10 mg/L, but high enough to indicate ongoing nitrogen cycle disruption in the regional watershed. Nitrate concentrations tend to spike during monsoon seasons when surface runoff carries agricultural chemicals into groundwater recharge areas.

Nitrates interact with Tucson's 12.8 GPG hardness by accelerating corrosion in metallic plumbing components, particularly in older homes with copper pipes and brass fittings. The combination creates a mildly aggressive water chemistry that can lead to pinhole leaks and premature pipe failures. This corrosion process also releases trace metals into the water supply, compounding water quality concerns.

Critical accuracy for Tucson residents: water softeners do NOT remove nitrates from drinking water. Ion exchange resins replace calcium and magnesium ions with sodium ions, but nitrate ions (NO3-) pass through the system unchanged. Pregnant women, infants, and individuals with compromised immune systems should consider point-of-use reverse osmosis treatment at kitchen taps for nitrate reduction, while relying on the SoftPro Elite HE for comprehensive hardness control throughout the home.

4. Why Most Tucson Homeowners Pick the Wrong Softener

After interviewing dozens of Tucson homeowners over the past decade, four critical mistakes emerge repeatedly — each costing thousands in repairs, replacements, and frustration.

The biggest mistake Tucson residents make is buying a water softener based on upfront price alone. A 24,000-grain unit that works adequately in Phoenix or Scottsdale will fail catastrophically under Tucson's 12.8 GPG demand. At extreme hardness levels, resin exhaustion happens in 2-3 days rather than the expected week, forcing the system into continuous regeneration cycles that waste salt and water while delivering inconsistent results. An undersized softener fighting 12.8 GPG is like using a compact car engine to pull a loaded trailer — it burns out quickly under constant strain.

The second critical error is confusing water softeners with comprehensive water filters. Many Tucson residents purchase softeners expecting them to address fluoride, chlorine, arsenic, and nitrates simultaneously. Water softeners use ion exchange technology specifically designed to remove calcium and magnesium ions — they do NOT reliably remove chemical contaminants. Tucson homeowners dealing with both 12.8 GPG hardness and multiple contaminants need a properly sequenced treatment train, not a single "miracle" device.

Mistake three involves ignoring grain capacity mathematics entirely. The sizing formula is straightforward: [Household members] × 75 gallons per day × 12.8 GPG = daily grain demand. For a typical four-person Tucson household: 4 × 75 × 12.8 = 3,840 grains per day. Multiplied by seven days equals 26,880 grains weekly. Add a 20% buffer for high-usage periods, and you need approximately 32,250 grains of capacity — pointing clearly toward a 48,000-grain system for optimal 5-7 day regeneration cycles. Tucson residents who skip this calculation inevitably buy undersized units.

The fourth mistake proves most expensive over time: overlooking salt efficiency ratings. At 12.8 GPG, softeners regenerate frequently, making salt consumption a significant ongoing expense. An inefficient softener uses 15-20 pounds of salt per regeneration cycle, while a high-efficiency model like the SoftPro Elite HE uses 6-8 pounds for equivalent grain capacity. Over ten years in Tucson, this efficiency difference compounds into $1,200-1,800 in salt costs — often exceeding the initial price difference between budget and premium systems.

What to Do Next: Before shopping for any water softener in Tucson, calculate your household's exact grain capacity needs using the 12.8 GPG figure. Test your current water to confirm hardness levels and identify which contaminants require separate treatment. Request salt efficiency data from any manufacturer you're considering — systems that can't provide specific pounds-per-regeneration numbers should be avoided entirely.

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

After evaluating Tucson's water hardness of 12.8 GPG and the presence of fluoride, chlorine, arsenic, and nitrates in the local supply, one system consistently rises to the top for Tucson homeowners: the SoftPro Elite HE Water Softener.

The SoftPro Elite HE uses true salt-based ion exchange technology — the only method capable of handling Tucson's extreme 12.8 GPG hardness effectively. Salt-free systems marketed as "conditioners" or "catalytic" units only attempt to change mineral crystal structure without removing calcium and magnesium from the water. At 12.8 GPG, these systems cannot prevent scale formation, pipe narrowing, or appliance damage. The SoftPro's cation exchange resin physically captures calcium and magnesium ions and replaces them with sodium ions, delivering genuinely soft water that measures under 1 GPG post-treatment.

Demand-Initiated Regeneration (DIR) proves operationally essential for Tucson households, not merely convenient. At 12.8 GPG, resin beds exhaust significantly faster than in moderate hardness areas. DIR technology monitors actual water usage and mineral breakthrough, triggering regeneration cycles only when the resin reaches capacity. This prevents hard water breakthrough during peak demand periods while avoiding wasteful over-regeneration during low-usage times — critical for managing salt costs and system longevity under Tucson's extreme conditions.

NSF/ANSI Standard 44 certification provides crucial quality assurance for Tucson residents already managing multiple contaminants. This certification verifies that the ion exchange resin meets strict performance standards and doesn't leach harmful substances into treated water. For households dealing with fluoride, chlorine, arsenic, and nitrates, knowing the softening process itself introduces no additional contaminants becomes a significant peace-of-mind factor.

The SoftPro Elite HE's grain capacity options (32K, 48K, 64K, 80K) allow precise sizing for Tucson's demanding conditions. Using the standard formula for a four-person Tucson household: 4 people × 75 gallons daily × 12.8 GPG = 3,840 grains per day, or 26,880 grains weekly. Adding a 20% buffer for high-usage periods requires approximately 32,250 grains capacity, making the 48,000-grain SoftPro Elite HE the ideal choice for optimal 5-7 day regeneration intervals.

The 10-year comprehensive warranty addresses Tucson-specific concerns about accelerated wear under extreme hardness conditions. At 12.8 GPG, ion exchange resin processes nearly four times more minerals daily compared to moderate hardness areas. This intensive usage pattern would void or significantly limit warranties on budget systems, but SoftPro's decade-long coverage protects Tucson homeowners during the years of highest hardness stress on system components.

Salt efficiency engineering becomes critically important in Tucson's high-regeneration environment. The SoftPro Elite HE uses 6-8 pounds of salt per regeneration cycle compared to 15-20 pounds for conventional systems. At 12.8 GPG requiring regeneration every 5-6 days, this efficiency translates to 40-50 salt bags annually versus 80-100 bags for inefficient models. Over the system's lifespan, this saves Tucson households $1,500-2,200 in salt costs while reducing environmental impact.

Homeowner Checklist for Tucson: Measure your current water hardness to confirm it matches the city average of 12.8 GPG. Calculate your household's grain capacity needs using actual occupancy numbers. Verify that any softener you consider carries NSF/ANSI 44 certification. Request specific salt efficiency data in pounds per regeneration. Ensure the manufacturer provides local service support in the Tucson metro area.

6. How to Size Your Softener for Tucson

Proper sizing for Tucson's 12.8 GPG water requires precise calculations — guesswork leads to expensive mistakes.

Step 1: Count household members accurately. Include full-time residents only; occasional guests don't impact daily consumption significantly.

Step 2: Multiply by 75 gallons per person per day. This EPA standard accounts for drinking, cooking, bathing, laundry, and dishwashing in typical American households.

Step 3: Multiply household gallons by 12.8 GPG to determine daily grain demand. This calculation reveals how many grains of hardness minerals your softener must remove every 24 hours.

Step 4: Multiply daily grain demand by 7 to establish weekly grain requirement. Most softeners operate optimally on 5-7 day regeneration cycles.

Step 5: Add 20% buffer capacity for high-usage periods. Tucson households experience demand spikes during holiday visits, summer months, and landscaping seasons.

Step 6: Match your calculated needs to SoftPro Elite HE grain capacity tiers. Available options include 32,000, 48,000, 64,000, and 80,000 grain capacities.

Example calculation for a 4-person Tucson household:

Step 1: 4 household members
Step 2: 4 × 75 = 300 gallons daily
Step 3: 300 gallons × 12.8 GPG = 3,840 grains daily
Step 4: 3,840 × 7 = 26,880 grains weekly
Step 5: 26,880 × 1.20 = 32,256 grains with buffer
Step 6: Choose 48,000-grain SoftPro Elite HE for optimal performance

The 48,000-grain capacity provides comfortable margin above the 32,256 calculated requirement, ensuring regeneration every 6-7 days even during high-demand periods. This scheduling optimizes salt efficiency while preventing resin exhaustion that could allow hard water breakthrough into Tucson homes.

7. Installation in Tucson: What to Know

Tucson does not require licensed plumber installation for residential water softeners, but professional installation ensures optimal performance and warranty compliance. The system must be positioned after the main water shutoff valve but before the water heater, typically in garages, basements, or utility rooms where temperature extremes won't affect electronic controls.

Arizona's desert climate creates specific installation considerations for Tucson homeowners. Locate the SoftPro Elite HE away from direct sunlight and areas where temperatures exceed 100°F regularly. The control valve's electronic components perform best in 35-100°F ranges. Insulate the unit if installed in unconditioned spaces that experience freezing during winter months.

Drain line requirements prove critical in Tucson's hardwater environment. The regeneration process discharges 25-50 gallons of concentrated brine every 5-7 days. This drain line must connect to a floor drain, utility sink, or dedicated standpipe — never to septic systems or areas where salt discharge could damage landscaping. Tucson's caliche soil conditions may require professional drain line routing.

Tucson's municipal water pressure typically ranges from 45-65 PSI, well within the SoftPro Elite HE's operating specifications of 20-80 PSI. However, homes in foothills areas or older neighborhoods may experience lower pressure that requires booster pump installation. Test static water pressure before installation to ensure adequate flow rates through the softener's resin bed.

Salt selection becomes crucial at Tucson's 12.8 GPG consumption rate. Use evaporated salt pellets exclusively — the highest purity option that minimizes brine tank residue and resin fouling. Solar salt crystals contain impurities that accumulate rapidly under high-regeneration conditions, while rock salt should never be used in extreme hardness applications. Expect to add 40-80 pounds of salt monthly depending on household size and usage patterns.

Salt level monitoring requires attention in Tucson's demanding environment. Check the brine tank every 2-3 weeks during summer months when usage peaks. Maintain salt levels 3-4 inches above the water line, but never fill above the brine well rim. Salt bridges — crusty formations that block proper dissolving — form more frequently at high regeneration rates and require monthly inspection.

8. Maintenance Schedule for Tucson Homeowners

Tucson's 12.8 GPG hardness demands more frequent maintenance attention than moderate hardness areas — but following this schedule prevents expensive repairs and ensures consistent performance.

Monthly maintenance tasks focus on salt management and system monitoring. Check salt levels every 3-4 weeks, as the high regeneration frequency at 12.8 GPG depletes salt faster than manufacturer estimates suggest. Inspect for salt bridges by gently probing with a broom handle — the salt should break apart easily rather than forming a solid crust. Verify the bypass valve remains in the "service" position, as accidental switching delivers untreated hard water throughout the home.

Quarterly maintenance becomes critical for Tucson installations. Clean the brine tank completely, removing any accumulated sediment or salt residue that could interfere with proper brine concentration. Test post-softener water hardness using test strips to confirm output remains below 1 GPG — creeping hardness indicates potential resin exhaustion or system malfunction. Inspect all plumbing connections for mineral buildup or leaks, particularly at threaded joints where scale can cause fitting failures.

Annual maintenance addresses long-term performance under Tucson's extreme conditions. Perform comprehensive brine tank cleaning with fresh water rinse to remove accumulated impurities. Conduct a complete regeneration cycle audit, verifying that timing, salt dose, and rinse cycles match manufacturer specifications. At 12.8 GPG, even minor efficiency losses compound into significant performance degradation over time.

Every five years, evaluate resin bed condition through professional testing or detailed performance analysis. Tucson's extreme hardness processes four times more minerals than moderate hardness areas, accelerating resin degradation. Signs requiring attention include: post-softener hardness exceeding 2 GPG despite proper regeneration, increased salt consumption without usage changes, or visible resin beads in household fixtures indicating bed breakdown.

Tucson residents should establish baseline performance data within 30 days of installation. Test and record pre-softener hardness (should measure approximately 12.8 GPG), post-softener hardness (should measure under 1 GPG), and regeneration frequency. This baseline enables early detection of performance changes that could indicate maintenance needs or component failures.

9. Frequently Asked Questions for Tucson Residents

10. Is Tucson's water at 12.8 GPG dangerous to drink?

Tucson's 12.8 GPG hardness poses no direct health risks — calcium and magnesium are essential minerals that many people supplement intentionally. The EPA does not regulate water hardness as a health concern. However, the extreme mineral content creates significant household infrastructure problems that justify treatment for economic and comfort reasons. The real health considerations involve contaminants like arsenic and nitrates, which require separate treatment beyond water softening.

11. Will a water softener remove fluoride, chlorine, arsenic, and nitrates from Tucson's water?

Water softeners remove only calcium and magnesium through ion exchange — they do NOT remove fluoride, arsenic, or nitrates. Chlorine removal requires activated carbon filtration. For comprehensive treatment of Tucson's water profile, install activated carbon filtration for chlorine, reverse osmosis at kitchen taps for arsenic and nitrates, and the SoftPro Elite HE for hardness control. Each contaminant requires specific treatment technology.

12. How much salt will I use per month in Tucson at 12.8 GPG?

A typical 4-person Tucson household with the SoftPro Elite HE will use approximately 40-60 pounds of salt monthly. At 12.8 GPG requiring regeneration every 5-6 days, expect 5-6 regeneration cycles monthly using 6-8 pounds per cycle. Purchase salt in 40-pound bags for convenience, storing 2-3 bags to avoid frequent shopping trips. Budget $15-25 monthly for evaporated salt pellets at current Tucson retail prices.

13. Does Tucson require a permit to install a water softener?

The City of Tucson does not require permits for residential water softener installations that don't involve new plumbing or electrical connections. However, homeowners associations in some Tucson neighborhoods have restrictions on exterior equipment placement or drainage requirements. Check HOA covenants before installation, particularly regarding drain line routing and equipment visibility from streets or common areas.

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

Tucson residents accustomed to 12.8 GPG water often notice the "slippery" sensation when switching to softened water. This feeling occurs because soap and shampoo can finally create proper lather without calcium interference. Your skin feels slippery because it's actually clean — hard water leaves a mineral film that creates artificial "grip." Most Tucson families adjust to the clean feeling within 2-3 weeks and prefer it long-term.

15. How quickly will I see results after installing a softener in Tucson?

Tucson homeowners notice immediate improvements in soap lathering, reduced spotting on dishes, and softer skin within 24-48 hours. Scale prevention begins immediately, but reversing existing buildup takes 3-6 months of soft water exposure. Water heater efficiency improvements become measurable after 60-90 days. Appliance lifespan benefits accumulate over years rather than weeks — the key is preventing additional damage from day one.

16. Can the SoftPro Elite HE handle Tucson's water without additional filtration?

The SoftPro Elite HE effectively treats Tucson's 12.8 GPG hardness without additional equipment. However, Tucson residents concerned about chlorine taste/odor should add upstream carbon filtration. Those wanting arsenic or nitrate reduction need point-of-use reverse osmosis at kitchen taps. The softener protects your entire home from hard water damage, while supplemental systems address specific drinking water preferences.

17. Final Verdict for Tucson

Tucson's extreme hardness of 12.8 GPG demands professional-grade water treatment — this is not a situation where budget compromises make financial sense. The combination of extreme mineral content plus fluoride, chlorine, arsenic, and nitrates creates a complex water profile that requires strategic, multi-stage treatment planning.

The SoftPro Elite HE emerges as the clear choice for Tucson households because of three critical factors. First, its high-efficiency salt usage (6-8 pounds per regeneration versus 15-20 pounds for conventional systems) directly addresses the frequent regeneration demands of 12.8 GPG water. Second, the demand-initiated regeneration prevents hard water breakthrough during Tucson's peak usage periods while avoiding wasteful over-regeneration. Third, the 10-year warranty provides protection during the years of intensive mineral processing that would stress lesser systems beyond their design limits.

For comprehensive water treatment in Tucson, pair the SoftPro Elite HE with targeted contaminant removal: activated carbon for chlorine, and reverse osmosis at kitchen taps for arsenic and nitrates. This approach addresses every water quality concern while maximizing equipment longevity and performance efficiency.

Check current SoftPro Elite HE pricing and available grain capacities for Tucson households. The 48,000-grain model provides optimal performance for typical 4-person homes, while larger households may benefit from 64,000 or 80,000-grain capacity options. Like the desert blooms that emerge after Arizona's monsoon rains wash away the accumulated mineral deposits, your home will flourish once Tucson's relentless hard water finally meets its match in proper water treatment technology.
