Water Softeners

Water Softeners in Northern California

Not your typical water softener. Our whole-house systems soften your water and filter chlorine and chloramine in one tank, so every tap, shower and appliance gets soft, clean, better-tasting water.

Our take

Not your typical water softener

A typical softener does one job. It takes care of the hardness minerals that leave white spots and crusty scale. The chlorine smell in your shower and the taste at your tap stay the same.

Ours are whole-house filtration systems that also soften. The Puronics Hydronex iGen C and Defender iGen C pair high-capacity softening resin with ChloroShield Clearess media made for chlorine and chloramine, all in one tank at your main water line. Both are WQA certified as complete systems to NSF/ANSI 42, 44 and 372.

The iGen valve keeps track of how much water your home uses and recharges only when it needs to, so you don't waste salt or water.

Every system is sized to your free in-home hardness test and your household. Rather skip the salt? Look at salt-free conditioning, and we'll tell you straight which one fits your water.

Signs you have hard water

  • White spots on dishes, glasses and shower doors
  • Crusty scale on faucets, showerheads and kettles
  • Soap and shampoo that won't lather, and film in the shower
  • Dry, itchy skin or dull, hard-to-rinse hair
  • A water heater or dishwasher wearing out early
  • A chlorine or "pool" smell when you shower

Questions about water softeners

Softener or salt-free: which one do I need?

A softener gives you truly soft water: spot-free glasses, better lather and that soft-water feel. A salt-free conditioner leaves the minerals in the water but helps keep them from sticking as scale. Your free water test shows how hard your water is, and we'll tell you which one fits.

How much salt does a softener use?

It depends on how hard your water is and how much water your home uses. Our iGen valves recharge only when needed, which helps save salt. We deliver a full year of salt for $119.

Can I use potassium instead of salt?

Yes. Our softeners work with salt or potassium chloride.

What size softener do I need?

It depends on your hardness reading and how many people live in your home. We size it at your free water test, so it keeps up without being bigger than you need.

How much does a water softener cost?

Every home's water is different, so we price your system after your free in-home water test, once we know your hardness and household size. The test is free, and financing is available for up to 15 years.
