Every water problem, one honest fix

City homes and well homes need different things. We treat both — and we'll tell you what you don't need.

Whole-Home Water Filtration

Catalytic carbon at your main line removes chlorine, disinfection byproducts, and PFAS-class chemicals from every tap and shower in the house.

City water · recommendation after review

Reverse Osmosis Drinking Water

Under-sink, multi-stage purification brings your kitchen tap to bottled quality.

Available with whole-home systems

Water Softener Systems

High-efficiency softening where hardness is real. Raleigh city water is medium hardness, which can contribute to scale, cloudy glassware, and soap scum; we confirm the service address and water conditions before recommending equipment.

Wells & hard-water areas

Well Water Treatment

Air-injection oxidation ends orange staining and rotten-egg smell at the source. Acid neutralizing protects pipes from low-pH water.

Well water · built from test results

UV Disinfection

Class A ultraviolet purification neutralizes bacteria and viruses — the certification tier actually rated for well disinfection.

Well water add-on

Free Well Water Analysis

Every well is different. We test iron, hardness, pH, sulfur, and TDS at your kitchen sink before quoting a single dollar.

Your Water

Detected in Triangle utility water — above health guidelines

These levels are legal under federal limits. Independent health guidelines are far stricter. Raleigh Water and the Town of Cary — the two utilities covering most of the Triangle — both show it.

Guideline multiples shown are EWG health guidelines, not federal legal limits — HAA9/TTHM multiples reflect Cary's levels (the higher of the two).

3

A licensed plumber installs it

Installed by an NC-licensed plumbing contractor, usually in one visit. Lifetime warranty terms in your hand before you pay.

Check Our Work

Don't take our word for it. Look the components up yourself.

Most companies ask you to trust a logo. We name the actual media, tanks, and valves that go into your system — then publish the NSF listings for them so you can read the source yourself, before you buy.

Activated carbon

Jacobi carbon

The carbon used for chlorine, taste, and odor reduction. NSF company listing published.

NSF/ANSI 61

Gravel base

The polishing gravel under the media bed, on the NSF drinking-water components listing.

NSF/ANSI 44

Tank & control valve

The pressure tank and the valve that runs it, on the NSF cation-exchange softener listings.

Softening resin

ResinTech 10% crosslink

The resin that actually removes hardness, made in New Jersey. Current certificate published.

And here's the part most companies leave out: a company or component listing is not the same thing as a model-level performance certification. These listings show the components are NSF-listed — they are not a claim that a particular system is certified to reduce a specific contaminant. We'd rather explain that difference than let a badge imply something it doesn't. See all component listings and details →

FAQ

Fair questions

Doesn't our water meet all federal standards?

Yes — and that's the point. Federal legal limits were mostly set decades ago and haven't kept pace with the science on PFAS and disinfection byproducts. "Legal" and "what independent health scientists recommend" are two different numbers, sometimes hundreds of times apart.

What exactly is included in my quote?

A whole-home system sized to your home, professional installation by a licensed plumber, and a lifetime warranty. Depending on what your water needs, that can include softening, whole-home filtration and under-sink reverse osmosis — your specialist confirms exactly what fits on your call. Well homes get a water analysis first, since treatment depends on your actual water chemistry.

Do I need a softener too?

A water softener can help extend the life of water-using appliances by reducing mineral scale, while also helping reduce cloudy glassware, fixture staining, soap scum, and spotting. Raleigh city water is medium hardness, and many private wells benefit from softening as well. We confirm the service address and test well water first so the recommendation is based on your actual conditions.

Who does the installation?

NC-licensed plumbing contractors. In North Carolina, whole-home water treatment is licensed plumbing work — we only use licensed pros, and you can verify any license at the state board's public lookup.

What's the catch on the lifetime warranty?

You get the actual terms in writing with your quote — coverage, exclusions, and transferability — before you pay anything. If a company won't put its "lifetime warranty" on paper, ask why.

How fast can you install?

Most city-water installs happen within the same week, in a single visit of about 2–4 hours. Well systems install after your free water analysis, typically within a week of the test.
