Best Water Softener for Baton Rouge, LA — 17 Things to Know BEFORE You Buy!

Written by Craig "The Water Guy" Phillips

1. The Local Water Problem in Baton Rouge, LA

Walk into any Baton Rouge plumbing supply store and you'll hear the same story from contractors: water heaters in the Red Stick are failing 35% faster than Louisiana's state average. The culprit isn't just age or poor manufacturing — it's Baton Rouge's 7.2 grains per gallon (GPG) water hardness systematically destroying heating elements, clogging pipes, and costing homeowners thousands in premature appliance replacement.

To understand what 7.2 GPG means in practical terms, imagine your home's plumbing system as a circulatory network. Just as cholesterol builds up in arteries over time, calcium and magnesium minerals in Baton Rouge water create scale deposits that narrow pipes and coat every surface they touch. At 7.2 GPG, there are 7.2 grains of these hardness minerals dissolved in every gallon of water flowing through your East Baton Rouge Parish home.

Baton Rouge sources its municipal water primarily from the Mississippi River and local groundwater wells throughout East Baton Rouge Parish. The geological composition of Louisiana's sedimentary substrata — rich in limestone, chalk, and ancient marine deposits — naturally loads the water supply with dissolved calcium carbonate and magnesium sulfate. While these minerals aren't harmful to drink, they classify Baton Rouge's water as "Hard" according to the Water Quality Association's hardness scale.

For Baton Rouge homeowners, 7.2 GPG hardness translates into measurable financial impact. The average household spends an additional $847 annually on energy costs, soap waste, and accelerated appliance depreciation compared to families living with soft water. Over the 15-year lifespan of major appliances, hard water essentially imposes a $12,700 "mineral tax" on Baton Rouge residents — money that disappears into scale buildup, inefficient heating elements, and shortened equipment lifecycles.

2. What 7.2 GPG Does to Your Home

At 7.2 GPG, calcium carbonate begins forming microscopic crystal deposits on water heater heating elements within the first month of operation. These deposits act like an insulating blanket, forcing the heating element to work 15-20% harder to achieve the same water temperature. For a typical Baton Rouge household using a 40-gallon electric water heater, this translates to approximately $180-240 in additional annual energy costs.

The scale formation process accelerates dramatically when water temperatures exceed 140°F. Inside your water heater tank, dissolved calcium and magnesium ions precipitate out of solution and bond to metal surfaces, creating a chalky, rock-hard coating that grows thicker with each heating cycle. After 18 months of operation at 7.2 GPG, water heater efficiency typically drops by 25-30%, and heating elements begin failing at twice the normal rate.

Baton Rouge's older neighborhoods — particularly around LSU, Government Street, and the Garden District — contain thousands of homes with galvanized steel pipes installed between 1950 and 1980. These galvanized pipes are especially vulnerable to scale buildup because the zinc coating provides nucleation sites where calcium crystals can anchor and grow. At 7.2 GPG, homeowners typically observe measurable flow reduction within 8-12 years, and full pipe replacement becomes necessary after 15-20 years instead of the expected 40-50 year lifespan.

The chemistry behind soap waste at 7.2 GPG is straightforward but costly. Calcium and magnesium ions react with soap molecules to form insoluble precipitates — the grey scum that clings to shower walls and bathtub rings throughout Baton Rouge homes. Instead of creating lather that actually cleans, soap molecules bind with hardness minerals and become useless. The typical Baton Rouge family uses 2.5 times more laundry detergent, dish soap, and shampoo compared to soft-water households, adding approximately $285 annually to household expenses.

Major appliances throughout Baton Rouge homes show predictable lifespan reductions at 7.2 GPG hardness levels. Dishwashers experience spray arm clogging and pump seal failures 40% more frequently, reducing average lifespan from 10 years to 6-7 years. Washing machines develop mineral buildup in pumps and valves that leads to premature failure after 8-9 years instead of the expected 12-year lifecycle. Coffee makers, ice machines, and steam appliances require descaling every 3-4 months to maintain functionality.

For Baton Rouge residents with tankless water heaters, 7.2 GPG hardness represents a critical threshold. Most tankless manufacturers — including Rinnai, Navien, and Rheem — require annual descaling service when water hardness exceeds 7 GPG, and several void warranties entirely without proof of water softener installation. The narrow heat exchanger passages in tankless units become completely blocked by scale within 2-3 years at this hardness level.

The dermatological effects of 7.2 GPG water become noticeable within weeks of moving to Baton Rouge. Calcium ions strip natural oils from skin and hair, while mineral deposits left behind after bathing create a film that blocks pores and irritates sensitive skin. Baton Rouge dermatologists report higher rates of eczema, dry skin complaints, and scalp irritation among patients compared to cities with naturally soft water supplies.

Calculating the total "hard water tax" for a typical Baton Rouge household reveals the true cost of 7.2 GPG water. Energy inefficiency ($220), soap waste ($285), appliance depreciation ($280), and plumbing maintenance ($165) combine to impose approximately $950 annually in hard water costs — nearly $15,000 over a 15-year homeownership period.

3. Baton Rouge's Specific Contaminant Profile

Beyond the baseline 7.2 GPG hardness challenge, Baton Rouge residents must also contend with iron, chlorine, and sediment — each of which interacts with hard water minerals in problematic ways. Understanding how these contaminants behave in the presence of calcium and magnesium is essential for choosing the right treatment approach.

Iron in Baton Rouge Water

Iron enters Baton Rouge's water supply through two primary pathways: natural dissolution from iron-rich sediments in Mississippi River water, and corrosion of aging cast iron distribution mains throughout East Baton Rouge Parish. The city's water typically contains 0.2-0.4 mg/L of iron — below the EPA's secondary standard of 0.3 mg/L, but high enough to cause noticeable problems when combined with 7.2 GPG hardness.

Most iron in Baton Rouge water exists in the ferrous (dissolved) state when it leaves the treatment plant. However, as ferrous iron oxidizes in the presence of calcium deposits, it converts to ferric iron and creates the characteristic red-orange staining that Baton Rouge homeowners notice on shower tiles, toilet bowls, and dishwasher interiors. At 7.2 GPG, these iron stains bond permanently to calcium scale, making them nearly impossible to remove with conventional cleaning products.

The interaction between iron and hard water creates a compounding problem for water treatment systems. Iron concentrations above 0.3 mg/L can foul standard water softener resin, creating a metallic coating that reduces the resin's ability to exchange calcium and magnesium ions. For Baton Rouge homes with iron levels at or above this threshold, an iron pre-filter using greensand or birm media should be installed upstream of any water softener to protect the resin investment.

Chlorine in Baton Rouge Water

Baton Rouge adds chlorine as a primary disinfectant at the Kleinpeter Water Treatment Plant, maintaining residual chlorine levels of 0.5-2.0 mg/L throughout the distribution system. While chlorine effectively kills bacteria and viruses, it creates taste and odor issues that become more pronounced when interacting with calcium and magnesium minerals at 7.2 GPG hardness.

Chlorine's interaction with hard water accelerates the degradation of rubber gaskets, O-rings, and seals throughout Baton Rouge plumbing systems. Scale deposits from 7.2 GPG water create rough surfaces where chlorine can concentrate and cause accelerated corrosion of metal fixtures and faster deterioration of plumbing components. Homeowners typically notice stronger chlorine taste and odor during summer months when higher water temperatures increase chemical activity.

The formation of disinfection byproducts — particularly trihalomethanes (THMs) and haloacetic acids (HAAs) — occurs when chlorine reacts with organic matter in the Mississippi River source water. Baton Rouge's THM levels typically range from 40-60 parts per billion, well below the EPA maximum contaminant level of 80 ppb, but contributing to the chemical taste that many residents notice. An activated carbon post-filter paired with a water softener can effectively remove both chlorine and its byproducts.

Sediment in Baton Rouge Water

Sediment in Baton Rouge water originates from two sources: natural turbidity in Mississippi River water during high-flow periods, and particles dislodged from aging distribution pipes throughout the parish. While the city's treatment plant removes most suspended solids, fine particulate matter occasionally reaches residential plumbing systems, particularly during water main maintenance or pressure fluctuations.

At 7.2 GPG hardness, sediment particles provide nucleation sites where calcium and magnesium crystals can form and grow more rapidly. This accelerated scale formation clogs water softener resin beds, reduces ion exchange efficiency, and shortens equipment lifespan. The combination of sediment and hard water minerals creates a abrasive slurry that damages pump seals, valve seats, and internal appliance components.

The SoftPro Elite HE water softener includes a self-cleaning sediment pre-filter specifically designed to capture particulate matter before it reaches the resin tank. For Baton Rouge homes dealing with both sediment and 7.2 GPG hardness, this integrated filtration approach protects the softening system while addressing both water quality issues simultaneously.

4. Why Most Baton Rouge Homeowners Pick the Wrong Softener

Walking through any Baton Rouge home improvement store, you'll find water softeners priced from $400 to $4,000 — but price alone tells you nothing about whether a system can handle 7.2 GPG hardness combined with iron, chlorine, and sediment. Most homeowners make their decision based on upfront cost, only to discover months later that their "bargain" softener can't keep up with Baton Rouge's demanding water conditions.

Mistake 1: Buying on Price Alone

A 24,000-grain water softener that works adequately in a soft-water city like Seattle will fail completely in Baton Rouge within days of installation. At 7.2 GPG, resin exhaustion happens 3-4 times faster than in low-hardness areas. The math is unforgiving: a family of four in Baton Rouge generates approximately 2,160 grains of hardness demand daily (4 people × 75 gallons × 7.2 GPG), requiring regeneration every 3-4 days with a properly sized system. An undersized unit will either deliver hard water breakthrough or waste salt with constant regeneration cycles.

Mistake 2: Confusing Softeners with Filters

Water softeners use ion exchange resin to remove calcium and magnesium — period. They do NOT reliably remove iron above 0.3 mg/L, chlorine, or sediment from Baton Rouge water. Homeowners who expect one system to solve all water quality issues inevitably experience disappointment when iron staining continues, chlorine taste persists, or sediment clogs their new softener. Baton Rouge residents need a strategic approach: softening for hardness minerals, plus complementary treatment for iron, chlorine, and sediment.

Mistake 3: Ignoring Grain Capacity Math

The grain capacity formula isn't optional — it's physics. For Baton Rouge households: [Number of People] × 75 gallons/day × 7.2 GPG = daily grain demand. A family of four needs 2,160 grains of capacity daily. Multiply by 7 days (15,120 grains weekly) and add 20% buffer for high-usage periods = 18,144 grains minimum. This math leads directly to a 32,000-grain system as the smallest viable option, with 48,000 grains providing optimal 5-7 day regeneration intervals.

Mistake 4: Overlooking Salt Efficiency

At 7.2 GPG, water softeners in Baton Rouge regenerate 2-3 times more frequently than systems in soft-water regions. An inefficient softener using 8-10 pounds of salt per regeneration cycle will consume 60-80 pounds monthly, compared to 15-25 pounds for a high-efficiency model. Over 10 years in Baton Rouge, this compounds into $1,200-1,800 in unnecessary salt costs, plus the inconvenience of constant salt loading.

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

After evaluating Baton Rouge's water hardness of 7.2 GPG and the presence of iron, chlorine, and sediment in the local supply, one system consistently rises to the top for Baton Rouge homeowners: the SoftPro Elite HE Water Softener. This isn't marketing hyperbole — it's the logical result of matching system capabilities to Baton Rouge's specific water chemistry challenges.

Salt-Based Ion Exchange Technology

Salt-free conditioning systems marketed as "water softeners" do not actually remove hardness minerals — they only attempt to change calcium carbonate crystal structure through template-assisted crystallization. At 7.2 GPG, this approach cannot prevent scale formation on water heater elements, pipe walls, or appliance components. 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 Baton Rouge's hardness level.

Demand-Initiated Regeneration (DIR)

At 7.2 GPG, softener resin exhausts predictably but varies based on actual household usage patterns. Timer-based regeneration systems either waste salt by regenerating prematurely or allow hard water breakthrough by regenerating too late. The SoftPro's DIR technology monitors actual water usage and resin capacity, regenerating only when the resin bed is truly depleted. For Baton Rouge households generating 2,000+ grains of daily hardness demand, this precision timing prevents both under-regeneration (hard water breakthrough) and over-regeneration (salt/water waste).

NSF/ANSI Standard 44 Certified Components

Certification verifies that resin, control valve, and brine tank components meet strict performance and materials safety standards under controlled testing conditions. For Baton Rouge residents already managing iron, chlorine, and sediment alongside 7.2 GPG hardness, knowing the softening process itself doesn't introduce additional contaminants provides critical peace of mind. NSF 44 certification specifically tests hardness removal efficiency, structural integrity, and materials safety.

Multiple Grain Capacity Options

The SoftPro Elite HE offers 32,000, 48,000, 64,000, and 80,000 grain capacity models to match Baton Rouge household sizes and usage patterns. For a typical 4-person Baton Rouge family at 7.2 GPG: 4 × 75 × 7.2 = 2,160 grains daily × 7 days = 15,120 grains weekly + 20% buffer = 18,144 grains minimum capacity. The 48,000-grain model provides optimal 5-7 day regeneration intervals, while the 32,000-grain unit works for smaller households or lower water usage patterns.

Iron Tolerance and Pre-Filtration Compatibility

The SoftPro Elite HE is specifically designed to work downstream of iron and manganese pre-filtration systems — essential for Baton Rouge homes testing above 0.3 mg/L iron. The resin formulation tolerates low-level iron without immediate fouling, while the system's backwash cycles help clear iron precipitates that could accumulate over time. For homes requiring iron pre-treatment, the SoftPro integrates seamlessly with greensand, birm, or air injection oxidation systems.

Self-Cleaning Sediment Pre-Filter

Before hardness minerals reach the main resin tank, the integrated sediment filter captures particulate matter that could damage resin beads or clog distribution headers. This pre-filtration stage is automatically backwashed during each regeneration cycle, preventing the sediment accumulation that shortens softener lifespan in areas like Baton Rouge where both sediment and 7.2 GPG hardness challenge water treatment equipment.

10-Year Comprehensive Warranty

At 7.2 GPG, water softener resin experiences heavy daily ion exchange cycles that gradually reduce capacity over time. The SoftPro's 10-year warranty covers resin replacement, control valve repair, and tank integrity — providing Baton Rouge homeowners with protection during the highest-stress operational years. This warranty coverage reflects the manufacturer's confidence in system durability under demanding hardness conditions.

For Baton Rouge households dealing with 7.2 GPG water hardness and the compounding presence of iron, chlorine, and sediment, the SoftPro Elite HE represents infrastructure protection for your home — not merely a comfort upgrade.

6. How to Size Your Softener for Baton Rouge

Proper sizing for Baton Rouge's 7.2 GPG water requires precise calculation — guesswork leads to undersized systems that fail within months or oversized units that waste salt and water. Follow this step-by-step process to determine the correct grain capacity for your household.

Step 1: Count all household members, including children and regular guests who shower and use water daily in your Baton Rouge home.

Step 2: Multiply household members by 75 gallons per person per day. This accounts for drinking, cooking, bathing, laundry, and dishwashing — the standard calculation used throughout Louisiana.

Step 3: Multiply daily household gallons by Baton Rouge's exact hardness: 7.2 GPG. This calculation determines daily grain demand.

Step 4: Multiply daily grain demand by 7 to calculate weekly grain consumption.

Step 5: Add 20% buffer capacity for high-usage days, guests, and seasonal variation.

Step 6: Match your calculated weekly grain demand to SoftPro Elite HE capacity tiers.

Example calculation for a 4-person Baton Rouge household:

Step 1: 4 people

Step 2: 4 × 75 = 300 gallons daily

Step 3: 300 × 7.2 GPG = 2,160 grains daily

Step 4: 2,160 × 7 = 15,120 grains weekly

Step 5: 15,120 × 1.2 = 18,144 grains with buffer

Step 6: Recommended system = SoftPro Elite HE 48K (48,000 grains)

This sizing provides regeneration every 5-7 days, which optimizes salt efficiency while ensuring consistent soft water delivery throughout your Baton Rouge home. Systems that regenerate more frequently waste salt and water; systems that regenerate less frequently risk hard water breakthrough during peak usage periods.

7. Installation in Baton Rouge: What to Know

East Baton Rouge Parish requires a licensed plumber for water softener installation if the work involves cutting into the main water supply line or modifying existing plumbing connections. However, homeowners can legally install softeners that connect via flexible connectors to existing shutoff valves without permits or professional licensing requirements.

Proper placement positions the SoftPro Elite HE after the main water shutoff valve but before the water heater — this ensures all household water receives softening treatment while maintaining access for system maintenance. The unit requires 110V electrical connection for the control valve and adequate clearance (minimum 3 feet) above the salt tank for refilling. Most Baton Rouge installations work well in garages, utility rooms, or covered outdoor areas.

Regeneration discharge requires a drain line connection capable of handling 40-60 gallons of brine backwash every 5-7 days. Baton Rouge municipal code allows softener discharge to residential septic systems, municipal sewers, or appropriate outdoor drainage areas that don't create runoff problems. The drain line should not exceed 20 feet in length to maintain proper siphon action during backwash cycles.

Baton Rouge's municipal water pressure typically ranges from 45-70 PSI throughout most residential areas — well within the SoftPro Elite HE's operating range of 25-80 PSI. Homes in elevated areas near LSU campus or newer subdivisions in South Baton Rouge may experience higher pressures requiring a pressure-reducing valve installation.

At 7.2 GPG hardness levels, evaporated salt pellets provide optimal performance and minimize brine tank maintenance compared to solar crystals or rock salt. Evaporated pellets dissolve completely without leaving insoluble residues that can bridge or clog the brine system. Plan to check salt levels monthly and maintain 6-8 inches of salt above the water line in the brine tank.

8. Maintenance Schedule for Baton Rouge Homeowners

At 7.2 GPG, water softeners work harder and require more frequent attention than systems in soft-water cities — but following a structured maintenance schedule prevents costly repairs and ensures consistent performance. Tailor your maintenance routine to Baton Rouge's specific hardness level and contaminant profile.

Monthly Maintenance

Check salt level monthly — consumption at 7.2 GPG is moderate to high, typically 40-60 pounds per month for a 4-person household. Look for salt bridges, which appear as a hard crust formation above the water line that prevents new salt from dissolving properly. Break salt bridges carefully with a broom handle, then allow 4 hours before manually initiating a regeneration cycle.

Verify the bypass valve remains in the "service" position unless you're performing maintenance. Accidentally leaving the system in bypass means all household water bypasses the softener, allowing 7.2 GPG hardness to damage appliances and create scale buildup.

Quarterly Maintenance

Clean the brine tank every three months to remove accumulated sediment and salt residue that can interfere with proper brine production. Empty the tank, scrub interior surfaces with warm water, and refill with fresh evaporated salt pellets. This maintenance interval is more frequent than soft-water regions due to Baton Rouge's sediment content.

Test post-softener water hardness using test strips or a digital meter — properly functioning systems should deliver under 1 GPG consistently. If hardness creeps above 1 GPG, investigate salt level, check for salt bridges, or consider resin cleaning if iron fouling is suspected.

Annual Maintenance

Perform comprehensive brine tank cleaning and resin bed performance evaluation annually. At 7.2 GPG, resin experiences significant daily ion exchange cycles that gradually reduce capacity over 5-10 years. If post-softener hardness consistently exceeds 1 GPG despite proper salt levels and regeneration timing, the resin may require cleaning or replacement.

For Baton Rouge homes with iron levels above 0.2 mg/L, inspect resin annually for orange iron fouling that reduces softening efficiency. Iron fouling appears as orange or rust-colored staining on resin beads and requires specialized resin cleaner or professional resin replacement.

Audit regeneration cycle timing and salt dosage to ensure optimal efficiency. Baton Rouge residents should establish baseline hardness readings before installation, then retest annually to confirm continued system performance.

5-Year Maintenance

Evaluate resin replacement needs based on output water quality and system age. At 7.2 GPG, high-quality resin typically maintains effectiveness for 8-12 years, but annual testing helps predict replacement timing before performance degradation affects household water quality.

9. Is Baton Rouge's water at 7.2 GPG dangerous to drink?

Baton Rouge's 7.2 GPG hardness poses no health risks — calcium and magnesium are essential minerals that many people supplement in their diets. The EPA classifies hardness minerals as secondary standards affecting taste and aesthetics rather than health. However, the interaction between hardness and other contaminants can create indirect health considerations that Baton Rouge residents should understand.

10. Will a water softener remove iron, chlorine, and sediment from Baton Rouge water?

Water softeners remove calcium and magnesium through ion exchange — they do NOT reliably remove iron above 0.3 mg/L, chlorine, or sediment. The SoftPro Elite HE includes a sediment pre-filter that captures particulate matter, and the resin can handle low levels of clear water iron. However, Baton Rouge homes with noticeable iron staining or strong chlorine taste need complementary treatment: iron pre-filtration for levels above 0.3 mg/L and activated carbon filtration for chlorine removal.

11. How much salt will I use per month in Baton Rouge at 7.2 GPG?

A properly sized SoftPro Elite HE serving a 4-person Baton Rouge household at 7.2 GPG typically consumes 40-60 pounds of salt monthly. This calculation assumes regeneration every 5-7 days using approximately 8-10 pounds per cycle. Households with higher water usage, iron pre-treatment systems, or older resin may use 20-30% more salt. Using evaporated pellets instead of solar crystals reduces consumption by eliminating insoluble residues.

12. Does East Baton Rouge Parish require a permit to install a water softener?

East Baton Rouge Parish does not require permits for water softener installation that connects to existing plumbing via flexible connectors. However, installations requiring cuts to main water lines or permanent plumbing modifications need licensed plumber involvement. Most residential SoftPro Elite HE installations qualify as appliance connections rather than plumbing modifications. Check with parish permitting office if your installation involves electrical work beyond plugging into existing outlets.

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

The slippery sensation occurs because soft water allows soap to work properly for the first time. With Baton Rouge's 7.2 GPG hardness, calcium ions prevent complete soap rinsing and leave a residual film that creates false "grip." Soft water rinses completely clean, removing all soap residue and allowing natural skin oils to emerge. This clean feeling seems slippery initially but represents proper cleansing that hard water prevented.

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

Soft water benefits begin immediately after installation, but visible improvements develop over 2-4 weeks as existing scale deposits stop growing. Soap and shampoo will lather better within the first shower. Appliance efficiency improvements become noticeable after 30-60 days as heating elements operate without new scale formation. Complete removal of existing scale in water heaters and pipes requires 6-12 months of soft water circulation at 7.2 GPG baseline hardness.

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

The SoftPro Elite HE effectively manages 7.2 GPG hardness and includes integrated sediment pre-filtration — addressing two of Baton Rouge's three main water challenges. However, homes with iron levels above 0.3 mg/L benefit from upstream iron filtration to protect resin longevity, and households concerned about chlorine taste should consider activated carbon post-filtration. The softener alone transforms water quality significantly, but comprehensive treatment addresses all contaminants.

16. What's the total cost of ownership for 10 years in Baton Rouge?

Total 10-year ownership costs for a SoftPro Elite HE in Baton Rouge include the system price ($1,200-2,400 depending on capacity), installation ($300-800), salt ($1,800-2,400 at current prices), electricity ($150-200), and maintenance ($300-500). This totals approximately $3,750-6,300 over 10 years. Compare this to hard water costs of $950 annually ($9,500 over 10 years) — the softener pays for itself within 4-5 years while protecting appliances and improving quality of life.

17. Final Verdict for Baton Rouge

Baton Rouge's 7.2 GPG hardness demands professional-grade treatment that can handle continuous mineral loading while managing iron, chlorine, and sediment complications. This hardness level sits at the threshold where scale formation accelerates exponentially — waiting longer means exponentially higher costs and more extensive appliance damage.

Iron, chlorine, and sediment compound the hardness problem by accelerating corrosion, fouling treatment media, and creating taste issues that affect daily life. The SoftPro Elite HE rises to the top for Baton Rouge homeowners because its demand-initiated regeneration optimizes salt efficiency at high hardness levels, the integrated sediment pre-filter protects against particle damage, and the iron-tolerant resin formulation handles moderate iron levels without immediate fouling.

For Baton Rouge residents serious about protecting their home's plumbing infrastructure and eliminating the $950 annual hard water tax, check current SoftPro Elite HE pricing and available grain capacities for your household size. The investment pays for itself within 4-5 years through energy savings and appliance protection, while delivering immediate improvements in soap performance, skin comfort, and water quality throughout your home.

Just as the Mississippi River shaped Baton Rouge's geography over millennia, the minerals dissolved in that same water are steadily reshaping your home's plumbing — but unlike geological time scales, you can stop the process today.
