The Problem
Hard water mineral scale and calcium buildup clogging a shower head — a common problem in Ohio homes with hard water

Ohio Has Hard Water — And It Shows

Most Ohio homes sit on limestone-rich geology. The minerals that dissolve into your water clog showerheads, coat pipes, and wear out appliances years too soon.

Scale Inside Your Pipes and Water Heater Calcium deposits accumulate inside water lines and heating elements, reducing flow and forcing your water heater to work harder than it should.
Shortened Appliance Lifespans Dishwashers, washing machines, and coffee makers all wear out faster when hard water deposits build up in their heating elements and valves.
Soap That Doesn't Lather — and Skin That Stays Dry Hard water ions bond with soap and shampoo molecules, preventing a real lather and leaving residue on your skin and hair after every shower.
Spots and Film on Everything Glasses and dishes come out of the dishwasher cloudy. Shower doors develop a permanent film. Surfaces feel grimy even right after cleaning.
Ohio Water Hardness — At a Glance

Your Water Is Probably Harder Than You Think

Ohio's water hardness varies by source, but most municipalities and private wells fall into the "moderately hard" to "very hard" range — well above what most water quality professionals consider ideal for your home.

How the EC5 Works

Ion Exchange — Proven Technology, Engineered Precisely

The EC5 uses cation exchange resin — the same science water professionals have relied on for decades, refined into a smart, demand-based system that only activates when your home actually needs it.

01

Hard Water Flows In

Your home's incoming water — carrying dissolved calcium and magnesium ions — flows into the EC5 resin tank installed at the point of entry on your main water line.

02

Ion Exchange Removes Hardness

The resin beads inside the tank attract and hold calcium and magnesium ions, releasing a small amount of sodium in exchange. Hardness minerals are physically removed — not just altered or masked.

03

Soft Water to Every Tap

Softened water travels through every pipe in your home. The EC5's metered control valve tracks actual water use and triggers regeneration only when the resin needs it — not on a fixed timer.

What Changes

The Difference Soft Water Makes Throughout Your Home

Soft water makes a difference in every room — from your pipes and appliances to your skin, your dishes, and your laundry.

Plumbing Protected for the Long Run

Scale stops building up inside your pipes, showerheads, and fixtures. Water flows freely, and you stop replacing parts prematurely.

Appliances Last Longer

Water heaters, dishwashers, and washing machines run more efficiently and last significantly longer without mineral buildup coating their heating elements.

Real Lather, Cleaner Rinse

Soap and shampoo actually work the way they're supposed to. Skin feels softer, hair is less brittle, and you use noticeably less product.

Spot-Free Dishes and Surfaces

Dishes come out of the dishwasher clear. Shower doors and faucets stay clean without the constant battle against hard water film and scale.

Soft Water at Home

What Changes the Moment Your Water Is Soft

Ohio homeowners who make the switch notice the difference within the first few days — and it shows up in every room of the house.

Clean shower head with strong full water flow — soft water from a water softener keeps fixtures free of scale and buildup
Showers That Stay Clean No scale, no blocked jets, no white residue on the showerhead.
Beautiful clean kitchen with spotless dishwasher and fixtures — the result of soft water from a water softener
Fixtures That Stay Spotless Faucets, handles, and surfaces stop building up white scale. Your kitchen and bathrooms stay cleaner with less effort.
CleanStart laundry system — soft water makes clothes feel softer and last longer
Softer Clothes, Less Detergent Laundry rinses cleaner, feels softer, and holds color longer. Most households use significantly less detergent after softening.
Minimalist bathroom vanity with spotless chrome fixtures — no hard water scale or mineral buildup
Chrome That Stays Spotless No white rings, no scale buildup on faucets or vanity fixtures. Your bathroom stays cleaner without the constant scrubbing.
What the EC5 Addresses

What Gets Removed From Your Water

The EC5 is specifically engineered to tackle the hardness minerals that affect the vast majority of Ohio homes. Here is what the ion exchange resin actively removes from your incoming water supply.

Calcium (Ca++)

The primary contributor to hard water scale and the white deposits you see on showerheads, faucets, and inside your pipes and appliances.

Magnesium (Mg++)

The second hardness mineral. Works alongside calcium to form the scale deposits that clog plumbing and reduce appliance efficiency over time.

Dissolved Iron (Fe++)

Clear-water iron — ferrous iron dissolved in solution — can be reduced by the EC5 resin, helping prevent rust staining in sinks, tubs, and toilets.

The EC5 addresses hardness and dissolved iron. For chlorine, VOCs, or chemical contaminants, the QRS carbon system is recommended — the two are often installed together.

Certifications and Standards

Independently Tested. Verified Performance.

Independent, third-party verification that the EC5 does what it claims.

Demand-Initiated Regeneration — your system only works when it needs to

NSF/ANSI Standard 44

The gold standard for residential cation exchange water softeners. Standard 44 independently verifies that the system reduces hardness minerals (calcium and magnesium) to certified levels. Not all softeners carry this — the EC5 does.

WQA Gold Seal

The Water Quality Association's Gold Seal program independently tests products for material safety and performance claims. WQA Gold Seal certification means the EC5 is verified safe for use with potable water.

Demand-Initiated Regeneration (DIR)

DIR systems are recognized by the WQA and EPA as more water- and salt-efficient than timer-based alternatives. The EC5 regenerates only when the resin is actually exhausted — based on your household's real water use.

Warranty and Support

A Warranty That Means Something

Built to Last. Backed Accordingly.

Limited lifetime coverage on the tank and valve body — the two components that matter most. That's not standard in this industry, and it reflects what we stand behind.

Schedule Your Free Water Test
Limited Lifetime — Treatment Tank The fiberglass resin tank is warranted for the life of the system under normal residential use.
Limited Lifetime — Valve Body The control valve body carries the same limited lifetime coverage — the component most likely to need attention over time.
Local Ohio Service Team Warranty service is handled locally by our Ohio technicians — not a national call center. We are the company that installed it and we stand behind it.
Ongoing Support Included Salt checks, system inspections, and water quality follow-ups are available throughout your ownership — because the relationship does not end at installation.

Common Questions

Straight Answers About Water Softening

The EC5 removes calcium and magnesium — the minerals responsible for hard water — plus dissolved iron in many cases. It does not address chlorine or chemical contaminants; those require a carbon filter like the QRS. Your water test will show exactly what your water contains.
Salt-free systems change the mineral structure so scale doesn't stick as easily — but they don't actually remove the minerals. The EC5 uses ion exchange to physically pull calcium and magnesium out of the water. That's the difference between reducing buildup and eliminating the source. NSF/ANSI 44 certifies the EC5 for measurable hardness reduction.
Very little. The EC5 uses Demand-Initiated Regeneration — it only regenerates when it actually needs to, not on a fixed timer — which makes it dramatically more salt-efficient than older softeners. Many homeowners are surprised how rarely they add salt. Your exact usage depends on household size and water hardness, both measured during the free water test, and a potassium chloride option is available if you'd rather avoid sodium entirely.
Softened water contains a small amount of added sodium from the ion exchange process. For most households this isn't a concern. If you're on a sodium-restricted diet, we typically recommend a reverse osmosis drinking water system at the kitchen tap — RO removes essentially everything, including sodium.
They solve different problems. The EC5 removes hardness minerals; the QRS removes chlorine, VOCs, and lead. Many Ohio homes benefit from both — and pairing them protects the EC5's resin from chlorine degradation, extending its life.
