What to know
- Removes hardness minerals (calcium and magnesium) — the source of scale in water heaters, tankless units, pipes, and fixtures.
- Reduces chlorine taste and odor for the whole house at the same time.
- The honest local fact: Seattle's supply runs about 1.3–1.4 grains per gallon and Everett's about 12 ppm (≈0.7 gpg) per the utilities' own reports — genuinely soft. Most city-water homes here don't need softening.
- Where it earns its keep: private wells, harder districts, and protecting tankless water heaters where hardness is present — some manufacturers condition warranty coverage on hardness limits.
- We test your actual water first and size the system to measured grains per gallon — or tell you to skip it.
What does hard water do to a home?
Hardness minerals come out of solution when water is heated — coating water-heater elements and tankless heat exchangers with scale, narrowing pipes, clouding glassware, and leaving crusty deposits on fixtures. Every bit of scale on a heating surface forces the equipment to burn more energy for the same hot water, and some tankless manufacturers condition their warranties on water hardness limits. In genuinely hard water, a softener pays for itself in equipment life alone.
Is Puget Sound water actually hard?
Mostly, no — and you deserve that answer before anyone quotes you a tank. Seattle Public Utilities' water analyses put city water around 1.3–1.4 grains per gallon (very soft), and the City of Everett's water quality report shows about 12 ppm total hardness (≈0.7 gpg) from its Sultan Basin supply. Softening buys those homes very little. The real hard-water cases here are private wells in Snohomish and Skagit counties — where mineral content varies parcel to parcel and can run many times city levels — plus some smaller districts that blend or pump ground water. One free test settles which water you have.
What does the FloTech system do?
One system, two jobs:
- Softening — ion-exchange resin captures calcium and magnesium before water reaches your water heater, fixtures, and appliances, releasing a trace of sodium in exchange.
- Chlorine reduction — strips the chlorine taste and odor from municipal water for the whole house, not just one faucet.
Who should get one — and who should skip it?
Our recommendation rules, in plain language:
- Get one: well-water homes with measured hardness, homes in harder districts, and tankless owners whose water tests above their manufacturer's warranty threshold.
- Consider filtration instead: Seattle/Everett city-water homes whose complaint is chlorine taste or sediment — that's a job for Halo whole-home filtration, not softening.
- Skip it: soft-water homes with no scale symptoms. If your test comes back soft, we'll say exactly that.
How do sizing and installation work?
Eco's licensed plumbers test your incoming hardness in grains per gallon, size the resin capacity to your household's usage, install the system to code with a proper bypass and the required drain air gap, and set the regeneration schedule so it's efficient rather than wasteful. If you're installing a new tankless unit in hard water, adding treatment at the same time is the single best thing you can do to protect the investment.

Common questions
Do I need a water softener in Seattle?
Probably not for hardness — Seattle Public Utilities' own analyses show very soft water (about 1.3–1.4 grains per gallon), and Everett city water is similar. If your complaint is chlorine taste or sediment, whole-home filtration is the better tool. The clear yes cases are private wells and harder districts — which is why we test before we recommend.
How do I know if I have hard water?
White scale on faucets and showerheads, spotted glassware, soap that won't lather, dry skin after showers, and a water heater that rumbles are all classic signs. We test your actual hardness in grains per gallon during a free assessment so the system is sized to reality.
Does a water softener make water taste salty?
No — properly configured softening leaves no salty taste. The sodium added during ion exchange is small, and the FloTech's chlorine reduction usually makes water taste noticeably better than before.
Will a softener help my tankless water heater warranty?
Often, yes — where your water is actually hard. Some tankless manufacturers require hardness below roughly 7 grains per gallon for full coverage and may deny scale-related claims well above that. A softener keeps hard water inside those limits and protects the heat exchanger itself. On soft city water, your warranty doesn't need the help.
How much maintenance does a softener need?
Mainly keeping the brine tank stocked with salt and an occasional settings check. We set the regeneration schedule to your measured hardness and household size at install so it doesn't waste salt or water, and Eco Care members get it checked at their annual plumbing evaluation.
