Best Water Softener for Riverside, CA — 15 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Riverside, CA

Your tankless water heater's warranty just became worthless. That's the reality for thousands of Riverside homeowners who don't realize their city's water measures 17.2 grains per gallon (GPG) — a hardness level so extreme it voids most appliance warranties within the first year of installation.

To understand what 17.2 GPG means, imagine your water pipes as arteries in your home's circulatory system. At this hardness level, calcium and magnesium minerals are flowing through your plumbing like concrete mix. Every gallon contains enough dissolved rock to leave visible deposits on everything it touches — from your coffee maker's heating element to your shower doors to the internal components of your $3,000 tankless water heater.

Riverside's water supply comes primarily from groundwater wells drawing from the Bunker Hill Basin and the Riverside North Basin, both geological formations rich in limestone and calcium carbonate. This geological reality means Riverside's water is classified as "extremely hard" — the highest category on the water hardness scale. For comparison, cities with "soft" water measure 0-1 GPG, while "moderately hard" water ranges from 3.5-7 GPG. At 17.2 GPG, Riverside residents are dealing with water that's nearly three times harder than the threshold for "very hard" water.

The financial stakes are immediate and measurable. A typical Riverside household at 17.2 GPG hardness pays an estimated $2,800 annually in what water quality experts call the "hard water tax" — extra costs from increased soap usage, accelerated appliance replacement, higher energy bills, and premature plumbing repairs. Over a 10-year period, that's $28,000 in preventable expenses.

2. What 17.2 GPG Does to Your Home

At 17.2 GPG, your water heater loses 35-45% of its efficiency within 18 months. Here's the science: calcium carbonate precipitates out of solution when heated, forming crystalline deposits that coat heating elements like concrete. In Riverside's extremely hard water, these scale deposits accumulate at a rate of approximately 0.8 inches per year on unprotected heating surfaces.

For a standard 40-gallon electric water heater, this means the lower heating element — which does 80% of the work — becomes encased in a limestone-like shell that blocks heat transfer. Your energy bills climb 40% higher than they should be, while your morning shower runs out of hot water twice as fast. Gas water heaters fare slightly better but still lose 25-30% efficiency as scale blocks the heat exchanger surfaces.

Riverside's pipe infrastructure, much of it installed during the city's growth boom in the 1980s and 1990s, faces accelerated aging under 17.2 GPG conditions. Copper pipes develop internal scale rings that reduce water flow by 20-30% within 8-12 years. Older galvanized steel pipes in established Riverside neighborhoods like Magnolia Center and Canyon Crest experience complete blockages within 15-20 years — half the expected lifespan in soft water areas.

The appliance damage timeline at 17.2 GPG is predictable and expensive. Dishwashers in Riverside homes require replacement every 6-8 years instead of the national average of 10-12 years. The spray arms clog with calcium deposits, the interior glass develops permanent etching, and the heating element fails prematurely. Washing machines lose efficiency as scale builds up on internal components, leading to poor cleaning performance and mechanical failures by year 7-9.

Coffee makers, ice machines, and steam appliances fail even faster in Riverside's water. Scale forms on heating elements within 3-6 months of daily use, causing these appliances to cycle on and off repeatedly as they struggle to maintain temperature. The result: a $150 coffee maker that dies within 18 months, an ice maker that produces cloudy, off-tasting cubes, and steam irons that spit brown mineral chunks onto clothing.

At 17.2 GPG, soap and detergent waste becomes a significant monthly expense. Calcium and magnesium ions react with soap to form insoluble precipitates — the gray scum ring in your bathtub — instead of creating cleansing lather. Riverside households typically use 3-4 times more soap, shampoo, and laundry detergent than families in soft water cities. For a family of four, this translates to an extra $85-120 monthly in cleaning product costs.

The personal effects are equally measurable. Extremely hard water strips natural oils from skin and hair, leaving both dry and irritated. Dermatologists in the Inland Empire report that eczema and sensitive skin conditions are 40% more common in hard water areas like Riverside compared to coastal California cities with softer water. Hair becomes brittle and difficult to manage as calcium deposits coat individual hair shafts.

3. Riverside's Specific Contaminant Profile

Beyond the crushing 17.2 GPG hardness baseline, Riverside residents are also contending with chloramine, iron, and fluoride — each of which interacts with water hardness in its own problematic way.

Chloramine in Riverside's Water System

Riverside Water uses chloramine as its primary disinfectant — a more stable but harder-to-remove chemical than standard chlorine. Chloramine forms when ammonia is added to chlorinated water, creating a disinfectant that persists longer in distribution systems. While effective at preventing bacterial growth throughout Riverside's extensive pipe network, chloramine creates a distinctive "band-aid" or medicinal odor that many residents notice, especially in summer months when concentrations are highest.

At 17.2 GPG hardness, chloramine interacts with scale deposits in concerning ways. The calcium carbonate buildup in pipes provides surface area where chloramine can react with organic matter, potentially forming disinfection byproducts like nitrosamines. Additionally, chloramine is corrosive to rubber gaskets and seals — a problem compounded by the scale formation that creates uneven surfaces and stress points in plumbing systems.

Standard activated carbon filters cannot effectively remove chloramine — it requires catalytic carbon, a specialized media that costs 2-3 times more than regular carbon. For Riverside residents with both extreme hardness and chloramine, a water softener alone will not address the chemical taste and odor issues.

Iron in Riverside's Groundwater

Iron concentrations in Riverside's water supply typically range from 0.2-0.8 mg/L, depending on which well field is serving your neighborhood on any given day. This iron exists primarily as ferrous iron — dissolved, invisible, and tasteless until it contacts oxygen and oxidizes into the familiar red-orange staining.

At 17.2 GPG, iron creates compounded problems because it bonds with calcium deposits to form incredibly stubborn rust-scale combinations. These iron-calcium matrices stain everything they touch with a reddish-brown discoloration that cannot be removed with standard cleaners. Riverside residents often notice this staining on toilet bowls, shower floors, dishwasher interiors, and white clothing items.

The EPA secondary maximum contaminant level for iron is 0.3 mg/L — a threshold exceeded in some Riverside neighborhoods during peak demand periods. More critically for softener operation, iron above 0.3 mg/L will foul ion exchange resin over time, reducing the system's ability to remove hardness minerals. This means Riverside homes with detectable iron need an iron pre-filter upstream of any water softener to protect the investment.

Fluoride Addition in Riverside

Riverside Water adds fluoride to the municipal supply at approximately 0.7 mg/L — the level recommended by the CDC for dental health benefits. This intentional addition means fluoride is present consistently throughout the distribution system, unlike naturally occurring contaminants that vary by season or well field.

It's crucial for Riverside residents to understand that water softeners do not remove fluoride. The ion exchange process that removes calcium and magnesium has no effect on fluoride ions. The EPA maximum contaminant level for fluoride is 4.0 mg/L (health-based) and 2.0 mg/L (aesthetic-based for dental fluorosis prevention). Riverside's 0.7 mg/L addition is well below both thresholds.

For residents who prefer to reduce fluoride intake, a reverse osmosis system at the kitchen tap is the most practical solution. This can be installed alongside a whole-house water softener to address both the hardness and fluoride concerns simultaneously.

4. Why Most Riverside Homeowners Pick the Wrong Softener

Walk through any big-box store in Riverside and you'll find water softeners marketed as "perfect for hard water" — but none of them are designed for 17.2 GPG performance. Here's what I wish someone had told me about the four critical mistakes that cost Riverside homeowners thousands in failed systems and ongoing water damage.

Mistake 1 — Buying on Price Alone

A $400 softener from a home improvement store cannot handle continuous 17.2 GPG demand. These units typically contain 24,000-32,000 grains of resin capacity — adequate for slightly hard water in cities like San Diego (3-4 GPG) but catastrophically undersized for Riverside conditions. At 17.2 GPG, a family of four exhausts 24,000 grains of capacity in less than two days, forcing the system into near-constant regeneration cycles that waste salt, water, and electricity while delivering inconsistent results.

The resin beads in budget units also use lower-grade materials that degrade rapidly under extreme hardness stress. Within 18 months, you'll notice hard water breakthrough — scale returning to fixtures and appliances despite having a "working" softener. The false economy of buying cheap becomes expensive quickly when your water heater fails and your dishwasher needs replacement.

Mistake 2 — Confusing Softeners with Filters

Riverside residents often assume a water softener will solve all their water quality issues — but softeners only remove hardness minerals through ion exchange. They do not reliably remove chloramine, iron, or fluoride. At 17.2 GPG with multiple contaminants present, you need a layered treatment approach.

A properly designed system for Riverside water starts with sediment filtration if needed, followed by iron removal if iron levels exceed 0.3 mg/L, then the water softener for hardness, and finally catalytic carbon filtration for chloramine. Installing just a softener and expecting it to address taste, odor, and staining problems leads to disappointed homeowners and continued water quality issues.

Mistake 3 — Ignoring Grain Capacity Math

Here's the sizing formula every Riverside homeowner needs to understand: [People] × 75 gallons/day × 17.2 GPG = daily grain demand. For a family of four: 4 × 75 × 17.2 = 5,160 grains consumed daily. Multiply by seven days and you need 36,120 grains of weekly capacity minimum.

Most homeowners never see this calculation and end up with drastically undersized systems. A 32,000-grain unit — adequate for moderate hardness — fails a Riverside household within six days. You need at least 48,000 grains for reliable operation, with 64,000 grains recommended for optimal 5-7 day regeneration cycles that maximize efficiency and resin life.

Mistake 4 — Overlooking Salt Efficiency

At 17.2 GPG, a water softener regenerates frequently — potentially every 3-4 days in a busy household. An inefficient system uses 12-15 pounds of salt per regeneration cycle, while a high-efficiency design uses 6-8 pounds for the same cleaning power. Over a year, this difference amounts to 800-1,200 pounds of extra salt — costing an additional $200-400 annually in Riverside.

Over the 10-15 year lifespan of a quality softener, salt efficiency savings compound into thousands of dollars. More importantly, efficient regeneration cycles use less water — a significant consideration during California's ongoing drought conditions and Riverside's tiered water pricing structure.

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

After evaluating Riverside's water hardness of 17.2 GPG and the presence of chloramine, iron, and fluoride in the local supply, one system consistently rises to the top for Riverside homeowners: the SoftPro Elite HE Water Softener.

Salt-Based Ion Exchange Technology

Salt-free systems do not actually remove hardness minerals — they only attempt to change crystal structure through template-assisted crystallization. While this approach might reduce scale formation in moderately hard water (7-10 GPG), it cannot handle Riverside's extreme 17.2 GPG mineral load. The SoftPro Elite HE uses true cation exchange resin to physically replace calcium and magnesium ions with sodium ions — the only proven method that delivers genuinely soft water at this hardness level.

The ion exchange process is simple chemistry: hardness minerals have a positive charge and stick to specially designed resin beads that prefer calcium and magnesium over sodium. During regeneration, a concentrated salt solution flushes the accumulated hardness minerals down the drain and recharges the resin with sodium ions for the next cycle. This isn't water "conditioning" or "restructuring" — it's actual mineral removal that you can verify with a test strip.

Demand-Initiated Regeneration (DIR)

At 17.2 GPG, resin exhausts faster than in moderate hardness cities like Los Angeles or San Francisco. The SoftPro's DIR system uses a built-in water meter to track actual consumption and regenerates only when the resin is genuinely depleted — preventing hard water breakthrough (under-regeneration) and salt waste (over-regeneration).

For Riverside households, DIR isn't just a convenience feature — it's operationally essential. A timer-based system would either regenerate too frequently (wasting salt and water) or too infrequently (allowing scale damage during breakthrough periods). DIR adapts automatically to your family's usage patterns, vacation schedules, and seasonal water consumption changes.

NSF/ANSI Standard 44 Certified Performance

NSF certification verifies that the resin meets strict performance and materials safety standards — crucial for Riverside residents already managing chloramine and other chemical additives. The certification process includes testing for:structural integrity under high flow rates, capacity retention over multiple regeneration cycles, and materials safety to ensure the softening process doesn't introduce contaminants.

Many budget softener brands skip NSF certification to reduce costs, leaving homeowners with no independent verification of performance claims. At 17.2 GPG, where system reliability is critical, NSF certification provides peace of mind that your investment will perform as advertised.

Multiple Grain Capacity Options

The SoftPro Elite HE comes in 32,000, 48,000, 64,000, and 80,000-grain configurations — allowing precise sizing for Riverside's extreme hardness conditions. Using the sizing formula from Section 4, a typical four-person Riverside household needs approximately 36,000 grains weekly. The 48,000-grain unit provides adequate capacity, while the 64,000-grain model offers optimal 5-7 day regeneration intervals that maximize salt efficiency and resin life.

Larger households or homes with high water usage (pools, irrigation systems, multiple bathrooms) should consider the 80,000-grain capacity. The key is matching grain capacity to actual demand rather than guessing or buying the cheapest option.

10-Year Limited Warranty Coverage

At 17.2 GPG, softener resin sees heavy daily mineral loading that would overwhelm systems designed for moderate hardness areas. The SoftPro's 10-year warranty provides Riverside homeowners with protection during the critical years when extreme hardness stress is highest. This warranty covers the control valve, resin tank, and internal components — not just basic parts like many competitor warranties.

The warranty also reflects the manufacturer's confidence in the system's ability to handle extreme hardness conditions long-term. Companies offering 90-day or 1-year warranties on their softeners are essentially admitting their products aren't built for markets like Riverside.

Iron and Manganese Pre-Filter Compatibility

The SoftPro Elite HE is engineered to work downstream of iron-specific filtration media — essential for Riverside neighborhoods where iron concentrations approach or exceed 0.3 mg/L. The system's control valve can be programmed to account for pre-filter pressure drop, and the resin tank connections accommodate the plumbing configuration needed for multi-stage treatment.

This compatibility prevents the iron fouling that would otherwise shorten resin life and reduce hardness removal efficiency. For Riverside homes with detectable iron staining, the ability to integrate iron removal upstream of the softener protects your investment and ensures consistent performance.

High-Efficiency Salt Usage

The SoftPro Elite HE uses 6-8 pounds of salt per regeneration cycle — approximately 40% less than conventional softeners of similar capacity. At Riverside's 17.2 GPG consumption rate, this efficiency translates to significant annual savings. A four-person household using the 64,000-grain model will consume approximately 350-450 pounds of salt annually, compared to 600-800 pounds for a less efficient system.

For Riverside homeowners dealing with both extreme hardness and California's environmental consciousness, salt efficiency matters beyond just cost savings. Less salt usage means less sodium discharge to wastewater treatment facilities and reduced environmental impact — important considerations in a state focused on water conservation and quality protection.

6. How to Size Your Softener for Riverside

Proper sizing is critical in Riverside because undersized systems fail rapidly at 17.2 GPG, while oversized units waste salt and water through inefficient regeneration cycles. Here's the step-by-step formula that accounts for Riverside's extreme hardness:

Step 1: Count household members (include any regular overnight guests or extended family)

Step 2: Multiply by 75 gallons per person per day (the national average for indoor water use)

Step 3: Multiply household gallons × 17.2 GPG = daily grain demand

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

Step 5: Add 20% buffer for high-usage days (parties, laundry catch-up, etc.)

Step 6: Match result to SoftPro Elite HE grain capacity (32K / 48K / 64K / 80K)

Let's work through this calculation for a typical four-person Riverside household:

Step 1: 4 people

Step 2: 4 × 75 = 300 gallons daily

Step 3: 300 gallons × 17.2 GPG = 5,160 grains daily

Step 4: 5,160 × 7 = 36,120 grains weekly

Step 5: 36,120 × 1.20 = 43,344 grains total capacity needed

Step 6: Match to 48,000-grain unit (minimum) or 64,000-grain unit (recommended)

The 64,000-grain SoftPro Elite HE is the optimal choice for this household because it provides 5-7 day regeneration intervals. This frequency maximizes salt efficiency, extends resin life, and ensures consistent soft water delivery even during high-usage periods. The 48,000-grain unit would work but would regenerate every 4-5 days, using more salt over time and working the system harder.

7. Installation in Riverside: What to Know

Riverside requires a licensed plumber for water softener installation that involves modifications to the main water line. The city's plumbing code follows California state regulations, which mandate permits and professional installation for any work upstream of the water heater or involving new drain connections.

Proper placement is critical for system performance and code compliance. The softener must be installed after the main water shutoff valve but before the water heater and any branches serving irrigation systems. This ensures all indoor water receives treatment while protecting the softener from backpressure and allowing bypass capability for emergencies.

The regeneration process requires a drain connection within 20 feet of the unit. Most Riverside homes have utility room floor drains, laundry standpipes, or utility sinks that satisfy this requirement. The drain line must be properly air-gapped to prevent contamination — a detail that professional installers understand but DIY attempts often miss.

Riverside's municipal water pressure typically ranges from 45-65 PSI throughout most residential areas — well within the SoftPro Elite HE's operating range of 25-80 PSI. Homes in elevated neighborhoods like Canyon Crest or areas near pressure-reducing stations may have lower pressure that affects regeneration performance. A pressure test during installation ensures optimal operation.

At 17.2 GPG hardness, use only evaporated salt pellets in your brine tank. Solar salt crystals and rock salt contain impurities that accelerate resin fouling and create brine tank residue at high regeneration frequencies. Evaporated pellets cost 20-30% more but provide the purity needed for reliable operation in extremely hard water conditions.

Check salt levels monthly in Riverside conditions. A 64,000-grain system serving a four-person household will consume 30-40 pounds of salt monthly. Keep the brine tank at least half full but never fill above the water level — salt should dissolve completely between regenerations rather than forming a solid mass.

8. Maintenance Schedule for Riverside Homeowners

Riverside's 17.2 GPG hardness accelerates wear on all softener components, making proactive maintenance essential for protecting your investment. Here's a maintenance calendar calibrated specifically for extreme hardness conditions:

Monthly Tasks

Check salt level and consumption rate. At 17.2 GPG, salt usage is high — typically 30-40 pounds monthly for a four-person household. Monitor consumption patterns to identify any sudden increases that might indicate system problems or water usage changes.

Inspect for salt bridges — crystalline crusts that form above the water line and prevent proper dissolving. Salt bridges are more common in high-hardness areas due to frequent regeneration cycles. Break up any bridges with a broom handle and ensure salt dissolves completely.

Verify bypass valve position. The control valve should be in "service" position for normal operation. Accidentally leaving the system in bypass means untreated 17.2 GPG water reaches your appliances and fixtures.

Quarterly Tasks (Every 3 Months)

Clean the brine tank thoroughly. High regeneration frequency in Riverside conditions creates more sediment buildup than in moderate hardness areas. Remove remaining salt, scrub the tank with mild detergent, and rinse completely before refilling.

Test post-softener water hardness with test strips. Properly functioning softeners should deliver water under 1 GPG. Any reading above 2-3 GPG indicates resin exhaustion, iron fouling, or system bypass issues that need immediate attention.

Inspect iron pre-filter if applicable. Riverside homes with iron removal systems should check filter cartridges quarterly. Iron-fouled media turns orange-brown and loses effectiveness, allowing iron to reach and damage the softener resin.

Annual Maintenance

Perform complete brine tank cleaning and sanitization. Disassemble removable components, scrub all surfaces, and use a mild bleach solution to eliminate any bacterial growth. High salt concentrations generally prevent bacterial problems, but annual sanitization ensures optimal performance.

Conduct resin bed performance evaluation. If post-softener hardness creeps above 1 GPG despite proper salt levels and tank cleaning, the resin may need cleaning with specialized resin cleaner or replacement. At 17.2 GPG, resin typically requires cleaning every 2-3 years.

Audit regeneration cycle timing and salt dosage. Verify that regeneration frequency matches your household's actual water consumption. Usage changes (new family members, teenagers, lifestyle changes) may require capacity adjustments.

Check for iron fouling signs. Orange or reddish-brown discoloration in the resin tank indicates iron contamination that reduces softening capacity. Iron-fouled resin requires specialized cleaning chemicals or replacement.

Five-Year Evaluation

At 17.2 GPG, assess overall resin condition and system performance. Extreme hardness conditions degrade resin faster than moderate hardness environments. Signs of resin replacement needs include: consistently high post-treatment hardness, excessive salt usage, shortened time between regenerations, and visible resin bead degradation.

Professional system inspection is recommended every five years in Riverside conditions. A qualified technician can evaluate control valve operation, internal seals and gaskets, resin bed depth and condition, and overall system efficiency to determine whether major maintenance or replacement is needed.

TIP: Riverside residents should establish baseline hardness readings before installation and retest 30 days after to confirm proper system operation. Keep these test results for comparison during annual maintenance checks.

9. Is Riverside's water at 17.2 GPG dangerous to drink?

No, 17.2 GPG hardness does not pose health risks — calcium and magnesium are essential minerals that many people take as supplements. The EPA does not regulate water hardness as a health concern, and some studies suggest moderate mineral intake through drinking water may provide cardiovascular benefits. However, the practical problems of extremely hard water — appliance damage, skin irritation, soap waste — make treatment advisable for quality of life and financial reasons.

10. Will a water softener remove chloramine from Riverside's water?

No, standard water softeners do not remove chloramine. The ion exchange resin that removes calcium and magnesium has no effect on chloramine molecules. Riverside residents concerned about chloramine's taste and odor need a catalytic carbon filter in addition to their water softener. The SoftPro Elite HE can be paired with a catalytic carbon system for comprehensive treatment.

11. How much salt will I use per month in Riverside at 17.2 GPG?

A typical four-person Riverside household will use 30-40 pounds of salt monthly with a properly sized SoftPro Elite HE system. This calculation assumes 300 gallons daily water usage and regeneration every 5-7 days. Larger families or homes with high water usage (pools, irrigation, multiple bathrooms) may use 45-60 pounds monthly. Track your actual usage for the first few months to establish your household's pattern.

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

Riverside requires permits for installations involving modifications to the main water line or new drain connections. Professional installations typically include permit costs in their pricing. DIY installations may not require permits if no new plumbing is added, but professional installation is recommended for warranty coverage and code compliance. Check with Riverside's Building and Safety Department for current requirements.

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

Soft water feels different because calcium ions no longer interfere with soap's cleansing action. In Riverside's 17.2 GPG water, calcium creates soap scum instead of lather, leaving a filmy residue on your skin that actually makes you feel "cleaner" but isn't. True soft water allows soap to work properly, creating more lather and rinsing completely clean — the slippery feeling is actually your natural skin oils without mineral interference.

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

Most Riverside homeowners notice immediate changes in soap lather and water feel, with appliance protection beginning instantly. Existing scale deposits take 2-4 weeks to gradually dissolve and flush away. White spots on dishes and glassware disappear within one wash cycle. Skin and hair improvements typically become noticeable within 7-10 days as residual mineral buildup clears. Complete scale removal from water heaters and pipes takes 3-6 months of soft water circulation.

15. Can the SoftPro Elite HE handle Riverside's water without separate filters?

The SoftPro Elite HE will effectively remove Riverside's 17.2 GPG hardness, but additional treatment may be needed for optimal results. If iron levels exceed 0.3 mg/L in your specific neighborhood, an iron pre-filter protects the softener resin. For chloramine taste and odor concerns, a catalytic carbon post-filter provides comprehensive treatment. Fluoride requires reverse osmosis if reduction is desired. The SoftPro's design accommodates multi-stage systems when needed.

Final Verdict for Riverside

Riverside's hardness of 17.2 GPG demands professional-grade treatment — this isn't a water quality issue you can ignore or address with budget solutions. The combination of extreme hardness with chloramine and iron compounds the challenge in ways that require systematic, engineered solutions rather than wishful thinking about "water conditioning" alternatives.

The SoftPro Elite HE rises above other options for Riverside homeowners because of three critical advantages: its high-capacity resin systems can handle continuous 17.2 GPG demand without premature exhaustion, its demand-initiated regeneration prevents the salt waste and breakthrough problems that plague timer-based systems in extreme hardness conditions, and its NSF certification provides verified performance standards that matter when system reliability is financially critical.

For Riverside households dealing with 17.2 GPG of water hardness and the compounding presence of chloramine and iron, the SoftPro Elite HE isn't a comfort upgrade — it's infrastructure protection for your home. The annual "hard water tax" of $2,800 in extra costs makes even a premium softener system pay for itself within 2-3 years, while providing 10-15 years of appliance protection and quality of life improvements.

Check current SoftPro Elite HE pricing and available grain capacities for your Riverside household size and usage patterns. At 17.2 GPG, waiting only increases the cumulative damage to your appliances, plumbing, and monthly budget.

The choice facing Riverside homeowners isn't whether to treat their water — it's whether to invest in proper treatment now or pay exponentially more in appliance replacements and energy waste while living with the daily frustrations that come with some of the hardest residential water in Southern California.
