Our systems
Thoughtfully selected for your home.
We treat the water where it enters your home, then add a dedicated reverse osmosis faucet at the kitchen sink. Every package is sized to your household and your water.
Whole-home
Legacy Premier whole-home filtration
Two tanks do two jobs. Carbon filtration reduces chlorine taste and odor in water serving your showers and taps. The second tank removes the hardness minerals that leave scale on fixtures and spots on glassware.
- Chlorine removed at every shower, bath, and sink
- Sized for your household's water use
- Installed near the main line by a licensed installer
- 10-year limited warranty
Softening
Water softening for the whole house
Hardness minerals build up inside water heaters, leave crust on faucets, and keep soap from lathering. Softening removes them before they reach your fixtures, helping reduce scale buildup and soap scum throughout the home.
- Removes the calcium and magnesium behind scale and spotting
- Protects water heaters, dishwashers, and fixtures
- Softer-feeling showers and less soap scum
- Recharges automatically; simple salt care explained before you buy
Drinking water
Legacy RO reverse osmosis
Multi-stage reverse osmosis with remineralization, delivered through its own kitchen faucet. Fill a glass, make coffee, and refill your bottle at home instead of hauling cases of water.
- Dedicated drinking-water faucet included
- Remineralization for finished-water taste
- Filters and storage tank fit beneath the sink
- 5-year limited warranty

Your water in the North Bay
Your water source shapes the treatment plan.
Start with the supplier on your water bill or your private-well report. We review that information alongside your household concerns before recommending equipment.
Sonoma County
Russian River water, treated with chlorine
Santa Rosa, Petaluma, Rohnert Park, Cotati, Windsor, Sonoma, and Novato receive water drawn from the Russian River aquifer through Sonoma Water, blended with local wells in some cities, and disinfected before it reaches you. If taste or odor is a concern, we review your supplier’s report and explain the filtration appropriate for your home.
Marin County
Reservoir water from Mt. Tam and Stafford Lake
San Rafael, Mill Valley, Sausalito, Tiburon, Corte Madera, Larkspur, and the Ross Valley get reservoir water from Marin Water; Novato is served by North Marin Water District. Use your supplier’s water-quality report to understand your supply. We plan whole-home filtration, softening, and kitchen RO around your water and the improvements you want to make.
Private wells
Sebastopol, Healdsburg, Sonoma Valley, and West Marin
Well water isn't disinfected or filtered before it reaches your home, and it varies from one property to the next. We start with a lab analysis, then build the treatment around what's actually in your well: sediment prefilters, iron or hardness treatment, and UV disinfection where it's needed.
Want the official numbers? Every public utility publishes an annual water-quality report. Bring yours to the consultation, or ask us and we'll pull the current report for your city and walk through it with you.

Questions
Your questions, answered.
How much does a whole-home system cost in Sonoma, Napa, or Marin County?
It depends on your home's size, water source, and where the equipment goes, which is why we quote each home individually. Your written quote lists the equipment, installation, faucet, and warranties as one installed price, and easy payment plans are available for qualified buyers.
What does the softener do for my home?
It removes the calcium and magnesium that build scale inside water heaters and dishwashers, leave spots on glasses and shower doors, and keep soap from rinsing clean. Paired with whole-home carbon filtration, it treats the water before it reaches any fixture in the house.
Does the whole-home system remove chlorine from the shower?
Whole-home carbon filtration reduces chlorine before the water reaches your showers and household taps. We explain the selected system’s treatment capabilities and maintenance at your consultation.
Does Legacy RO supply every faucet in the house?
No. Legacy RO serves a dedicated drinking-water faucet at the kitchen sink. The whole-home system handles the rest of the house.
What maintenance does the system need?
The softener needs salt added periodically, and the carbon media and RO filters have service intervals we'll explain before you buy. We show you how to check everything during the walkthrough.
I'm on a well. Can you help?
Yes. Well homes start with a lab water analysis, and we build the treatment around the results: sediment prefilters, hardness or iron treatment, and UV disinfection where needed.
Who does the installation?
A licensed installer based in the North Bay handles every Sonoma, Napa, and Marin install. Family First Water sizes the system, writes the quote, and stays your point of contact before and after.
What's covered by the warranty?
The whole-home system carries a 10-year limited warranty and Legacy RO carries a 5-year limited warranty. You'll receive the written terms with your quote.
