That’s exactly where we come in. We’re experts in water treatment and highly familiar with the water quality across the entire Bay Area, Silicon Valley, Northern California, and the Central Coast. We've studied the local water reports and understand the unique challenges in each region—from hard water to high contaminant levels. We’ll assess your specific needs and recommend the right system to give you clean, high-quality water at home.

Mostly no. About 90 percent of Mountain View is on Hetch Hetchy water at roughly 3.5 grains per gallon, which is soft. South of Cuesta Drive the supply is treated Valley Water at about 5.7 grains per gallon, which is moderately hard. Both are chloraminated. The exception is the city's own wells, which serve specific pockets near Evelyn and Castro, around Moorpark, and north near Rengstorff, and run 12.9 to 19.8 grains per gallon. That is very hard. A small area east of Grant Road near Highway 85 is served by California Water Service on a blend of 72 percent Valley Water and 28 percent well water. Supply and disinfectant figures come from Valley Water's retailer map, and hardness from the 2025 water quality reports. Because the answer depends on your street rather than your city, we measure at your own tap at no charge.

Our water softener and filtration system are installed at your home’s main water entry point—before the water flows through the rest of your plumbing. From there, it filters and softens the water, delivering noticeable improvements throughout your entire home.

Because it is chloraminated rather than chlorinated, and that changes which filter works. Chloramine is chlorine combined with ammonia. It is more stable than free chlorine, which is exactly why it is used across a system the size of Hetch Hetchy, and exactly why it is harder to remove at your tap. Ordinary activated carbon, which is what a pitcher filter or a refrigerator cartridge uses, adsorbs free chlorine quickly but reduces chloramine poorly, because chloramine has to be catalytically decomposed rather than simply adsorbed. That takes catalytic carbon and considerably more contact time than a small cartridge can provide. What works is catalytic carbon, either under the sink or sized for the whole house, or a reverse osmosis system at the kitchen tap. Our Exchanger Pro RCC and Exchanger Elite RCC systems include catalytic carbon filtration that reduces chlorine, chloramine and ammonia at every tap in the house.

All of our systems are designed to be a long-term solution, with a lifespan of up to 15-20 years. You are covered under a 10 year warranty that covers all parts and labor.

All our water softener and reverse osmosis systems are made in the USA and tested & certified by the Water Quality Association against NSF/ANSI Standards.
