Get a Free QuoteWell water can carry iron, sulfur, bacteria, and hard minerals that city water never sees. The Flexx Combo is engineered specifically for the demands of private well water — pairing chemical injection and oxidation filtration with ion exchange softening in a single integrated system. One water test. One installation. Every problem solved.
The Flexx Combo handles the three most common well water problems simultaneously — using proven chemical injection, oxidation filtration, and ion exchange softening to deliver clean, soft, odor-free water from every tap in your home.
The Flexx inFusion Iron and Sulfur Filter uses a chemical injection system to introduce a precise oxidation solution into your water stream. Iron and hydrogen sulfide are oxidized on contact — converting dissolved iron into filterable particles and neutralizing sulfur gas. The result: no rust stains, no rotten egg smell, from every tap in your home. Effective on iron up to 10 ppm and hydrogen sulfide up to 15 ppm.
After iron and sulfur are eliminated, water flows through the Flexx Water Softener. Ion exchange resin swaps calcium and magnesium ions — the minerals responsible for scale buildup — for sodium ions. The result is genuinely soft water throughout your entire home: no scale on pipes, no residue on fixtures, no hard water damage to appliances. Well water hardness can reach 50+ grains per gallon; the Flexx Softener is sized to handle it.
Both components of the Flexx Combo use ceramic rotary disc valves — the same technology found in commercial water treatment equipment. Unlike plastic ball valves that crack or rubber diaphragm valves that wear out, ceramic disc valves maintain a precise, leak-free seal through tens of thousands of cycles. Rated for 10+ years of operation without service. The valve controls backwash, regeneration, and service cycles automatically.
The Flexx Combo installs on your main water line at the point of entry — treating all water before it reaches any fixture, appliance, or tap in your home. Every shower, every load of laundry, every glass of water benefits from the full treatment. No under-sink add-ons, no separate units for different areas of the house. One installation handles everything.
Well water systems are often undersized — the result is good water quality at low pressure, which defeats the purpose. The Flexx Combo is sized to your household's actual peak flow demand. The inFusion filter handles 10–15 GPM peak flow; the softener handles 15–20 GPM. Multiple showers, the dishwasher, and the laundry can all run simultaneously without pressure drop.
Chemical injection + oxidation filtration eliminates dissolved iron at concentrations up to 10 ppm — covering even high-iron wells that defeat standard iron filters.
Oxidation neutralizes hydrogen sulfide gas at the source, eliminating the rotten egg smell completely — from every tap, every shower, every appliance.
The inFusion filter removes manganese along with iron — preventing the black staining and bitter taste that manganese causes at concentrations above 0.05 ppm.
Commercial-grade ceramic disc valves on both components deliver 10+ years of reliable, leak-free automatic operation — no service calls, no premature failures.

Every well is different. Our technician tests your water on-site, designs the right configuration for your specific chemistry, and installs the complete system — usually in a single day.
We test your well water on-site — measuring iron, hydrogen sulfide, manganese, hardness, pH, and bacterial levels. You get a complete picture of exactly what your water contains.
Based on your results, household size, and well pump flow rate, we size the Flexx Combo to match your specific demands — peak flow, contaminant load, and regeneration frequency.
Our technician installs both components at your main water line, programs the controller, and confirms treated water quality before leaving. Clean water from every tap, same day.
The most common issues include hard water (excess calcium and magnesium), iron staining (orange/rust marks), hydrogen sulfide (rotten egg smell), bacterial contamination, low pH (acidic water that corrodes pipes), sediment, and elevated nitrates. What’s in your water depends on your local geology and well condition.
Watch for these signs: rust or orange stains on sinks, a rotten egg or metallic smell, cloudy or discolored water, scale buildup on fixtures, dry skin after bathing, or stiff, dingy laundry. But many contaminants — like bacteria and nitrates — are invisible. A professional water test is the only way to know for sure.
City water is treated and monitored by your local water authority before it reaches your home. Well water comes straight from an underground aquifer — untreated and unmonitored. That means you’re responsible for testing and treating your own water to make sure it’s safe for drinking, cooking, and bathing.
It depends entirely on what’s in your water. Iron? You need an iron filter. Bacteria? UV disinfection. Hard water? A softener. Bad taste? Carbon filtration. Dissolved contaminants in drinking water? Reverse osmosis. Most well water homes benefit from a combination of systems — which is exactly what our free water test helps determine.
Yes — but they require different systems. Iron filters remove the iron and manganese causing orange/rust stains. UV disinfection is the recommended solution for bacteria like E. coli and coliform — it destroys them without chemicals. We often install both together for comprehensive protection.
That smell is hydrogen sulfide gas dissolved in your water. The Flexx inFusion filter uses chemical injection and oxidation to eliminate hydrogen sulfide at concentrations up to 15 ppm. We measure the exact level during your free water test and confirm the Flexx Combo is the right treatment for your concentration.
No — filtration and softening are different processes. A filter removes contaminants like iron, sediment, and chemicals. A softener specifically targets hardness minerals through ion exchange. That’s exactly why the Flexx Combo includes both: the inFusion filter handles iron, sulfur, and manganese; the Flexx Softener handles hardness. You get both in a single integrated system.
We strongly recommend it. Wells are vulnerable to bacterial contamination from surface runoff, nearby agricultural activity, or a compromised well casing. Even if your current test shows no bacteria, conditions change. UV provides ongoing, chemical-free protection and peace of mind. The Flexx Combo can be paired with a UV system for complete well water treatment.
Simple point-of-use filters, maybe. But a whole-home well water treatment system requires proper sizing, plumbing connections, programming, and configuration to work correctly. Our trained installers handle everything — usually in a single day — so you get it right the first time.
For the Flexx Combo: the softener resin typically lasts the life of the system with proper salt maintenance; the inFusion filter media lasts several years depending on iron load. UV lamps (if added) are replaced annually. Your specific schedule depends on your water quality and usage — we’ll set you up with a maintenance plan during installation.
With proper maintenance, most systems last 10–20 years. The Flexx Combo’s ceramic rotary disc valves are rated for 10+ years of reliable operation. The keys to longevity: timely filter service, regular salt additions for the softener, and annual water testing to confirm performance.
Yes — at least once a year. Water quality changes over time due to seasonal variations, water table shifts, nearby land use, and well aging. Annual testing confirms your system is still performing and catches any new contaminants that might need additional treatment.
It depends on your household size, number of bathrooms, well pump flow rate, and the specific contaminants to address. Too small and it won’t treat effectively. Too large and you’re overpaying. Our technician evaluates all of these factors during your free water test.
For the Flexx Combo: add salt to the softener brine tank (approximately once a month), monitor system alerts, and have your water tested yearly. If you add UV, swap the lamp annually. Following the recommended schedule keeps your system running at peak performance and extends its life.
Absolutely — that’s one of the biggest benefits. Hard water causes scale in pipes and water heaters. Acidic water corrodes copper plumbing. Iron clogs valves and reduces flow. A properly designed system protects your entire plumbing infrastructure, reduces repair costs, and helps appliances run more efficiently for longer.
Yes. An acid neutralizer raises pH to protect plumbing. The Flexx inFusion filter removes dissolved iron, manganese, and hydrogen sulfide. The Flexx Softener removes hardness. We combine these into a single integrated system tailored to your specific water chemistry — no separate contractors or piecemeal solutions needed.
“We put up with sulfur smell for years thinking nothing could really fix it. The Flexx Combo eliminated it completely. We also had terrible rust staining on our sinks and toilets — gone. This system solved every well water problem we had in one shot.”
“Our iron levels were off the charts — orange staining everywhere, laundry ruined, appliances corroding. Three months after installation the staining has cleared, our water looks and smells clean, and the soft water is an added bonus we didn’t expect to appreciate as much as we do.”
“After the water test, we found out we had high iron, high hardness, and some sulfur. The team designed the combo system specifically for our well conditions. Six months in — the water is clean, clear, and completely odor-free. Best decision we’ve made for this house.”
Our local water experts will test your well water, explain the results in plain English, and recommend a custom system designed for your specific issues. No obligation, no pressure, no hidden fees.
