Water Treatment Services in Shreveport, LA

Improving Your Water Quality With Professional Filtration and Softening Solutions

The water that reaches your Shreveport home travels through miles of municipal infrastructure before it arrives at your tap. Along the way, it picks up chlorine, sediment, mineral hardness, and trace contaminants that affect taste, clarity, and the health of your plumbing system. Mark Johnson & Sons Plumbing installs and services water treatment systems that address these issues at the point of entry, giving you cleaner, better-tasting water throughout your entire home.

Why Water Treatment Matters in Shreveport

Shreveport’s municipal water supply, managed by the City of Shreveport Water Department, draws primarily from Cross Lake and is treated to meet EPA standards before distribution. While the water is safe to drink by regulatory standards, “safe” and “ideal” aren’t the same thing. Shreveport’s water reports consistently show moderate to high levels of water hardness — the result of calcium and magnesium dissolved from the geological formations in the Red River region.

Hard water creates problems you can see and feel every day. White mineral deposits form on faucets, showerheads, and glass surfaces. Soap lathers poorly, leaving skin feeling dry and hair looking dull. Laundry fades faster and feels stiff. Inside your plumbing, the consequences are more expensive — scale builds up inside water heaters, reducing efficiency and shortening equipment life. Supply lines gradually narrow as mineral deposits accumulate along interior walls.

Beyond hardness, Shreveport residents may notice chlorine taste and odor from the disinfection process, occasional sediment after water main work in their neighborhood, or concerns about trace contaminants that meet federal limits but exceed personal comfort levels. A properly selected and installed water treatment system addresses these concerns at the source, before the water reaches any fixture in your home.

Our Water Treatment Services

Whole-House Water Filtration

A whole-house filtration system treats every drop of water entering your home — not just what comes from the kitchen tap. We install systems that remove chlorine, sediment, volatile organic compounds, and other contaminants based on a water test that identifies exactly what your Shreveport home’s supply contains. The result is cleaner water from every faucet, shower, and appliance.

Water Softener Installation and Service

Water softeners remove the calcium and magnesium minerals that cause hard water problems. We install both salt-based ion exchange systems and salt-free conditioning systems depending on your preferences, water hardness level, and household needs. Proper sizing ensures the system handles your family’s daily water usage without running out of capacity between regeneration cycles.

Under-Sink and Point-of-Use Filtration

For homeowners who want enhanced filtration at a specific location — typically the kitchen for drinking and cooking — we install under-sink reverse osmosis systems and carbon filtration units. These compact systems fit inside standard kitchen cabinets and deliver purified water through a dedicated faucet mounted on your sink.

Water Testing

Before recommending any treatment system, we test your water to understand exactly what’s in it. Our testing covers hardness, pH, chlorine levels, iron, manganese, total dissolved solids, and other parameters that determine which treatment approach will be most effective for your specific water supply.

System Maintenance and Filter Replacement

Every water treatment system requires periodic maintenance to continue performing effectively. We service all major brands — replacing filters, replenishing salt, cleaning resin beds, checking system pressures, and verifying output water quality. Regular maintenance protects your investment and ensures consistent water quality year-round.

Frequently Asked Questions

Is Shreveport’s water safe to drink?

Shreveport’s water meets all EPA safety standards for municipal water supplies. However, meeting federal minimums doesn’t address personal preferences around taste, odor, hardness, or trace contaminant levels. Many Shreveport homeowners choose water treatment to go beyond the baseline and achieve the water quality they prefer.

How hard is Shreveport’s water?

Shreveport’s water hardness typically falls in the moderately hard to hard range, generally between 7 and 12 grains per gallon depending on the source and time of year. This level is high enough to cause noticeable scaling, soap performance issues, and accelerated wear on water heaters and appliances.

What does a whole-house water filtration system remove?

Depending on the system selected, whole-house filters can remove chlorine, sediment, volatile organic compounds, certain pesticides and herbicides, and taste and odor-causing compounds. Systems with additional media can also target iron, manganese, and hydrogen sulfide. We match the filtration media to your specific water test results.

How much does a water softener cost in Shreveport?

A quality residential water softener typically costs $1,500 to $3,500 installed, depending on the system capacity, features, and any plumbing modifications needed. We provide a detailed quote that includes the unit, installation, and any necessary plumbing connections.

Salt-based vs. salt-free — which is better?

Salt-based softeners physically remove hardness minerals through ion exchange, which eliminates scale and provides the “soft water feel” most people associate with softened water. Salt-free conditioners alter mineral structure so they don’t form scale but don’t actually remove the minerals. Salt-based systems are more effective for high hardness levels; salt-free may suit homes with moderate hardness and preference to avoid salt.

How often do water treatment systems need maintenance?

Most systems need filter changes or salt replenishment every 3 to 6 months, with a full system inspection annually. Reverse osmosis membranes typically last 2 to 3 years before replacement. We can set up a maintenance schedule so your system stays at peak performance without you having to track service intervals.

Will a water softener affect my water pressure?

A properly sized and installed water softener has negligible impact on water pressure. Undersized systems or clogged resin beds can restrict flow, which is why proper sizing and regular maintenance are important. We calculate your home’s peak flow demand and select a unit that handles it without restriction.

Can water treatment help protect my water heater?

Absolutely. Scale buildup from hard water is one of the primary causes of water heater inefficiency and premature failure. A water softener dramatically reduces scale formation, helping your water heater operate efficiently and last longer. It’s one of the best investments you can make to protect a major appliance.

Do you install reverse osmosis systems?

Yes. We install under-sink reverse osmosis systems that remove up to 99 percent of dissolved contaminants, including lead, fluoride, arsenic, nitrates, and total dissolved solids. These systems include a dedicated faucet and storage tank that fit inside a standard kitchen cabinet.

Do I need to test my water before installing a system?

We strongly recommend it. Testing identifies the specific contaminants and hardness levels present in your water, which determines the right treatment approach. Installing a system without testing is guesswork — you might overspend on filtration you don’t need or miss a contaminant that requires targeted treatment.
