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.

No, and this is one of the few places where we can say that flatly. The City of Milpitas splits its supply geographically, but both sources are imported surface water and both are soft to moderately hard. The east side is on Hetch Hetchy at about 3.5 grains per gallon, which is soft. The rest of the city is on treated Valley Water at about 5.9 grains per gallon, which is moderately hard. There is no groundwater in the city's drinking water supply. Below about 7 grains per gallon a softener has little to do, and the salt, regeneration water and service calls are real ongoing costs against a problem you do not have. The cases where one still makes sense here are narrow: you are on the Valley Water side near the top of its range at 8.5 grains per gallon and seeing real scale, you have an appliance whose manufacturer specifies soft water, or you have measured and are not getting the numbers above, which does happen. Supply and disinfectant figures come from Valley Water's retailer map, and hardness from the City of Milpitas 2025 water quality report. We will measure your own tap at no charge, and if it comes back at 4 grains per gallon we will tell you to keep your money.

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 hardness is not the Milpitas water complaint. Taste and smell is. Both Milpitas supplies are treated with chloramine, which is chlorine combined with ammonia. It is more stable than free chlorine, which is exactly why it is used across a distribution system this large, and exactly why it is harder to get out of your water at home. Here is the part most people do not know: the pitcher in your fridge and the filter in your refrigerator door are good at removing free chlorine and much weaker on chloramine. Standard activated carbon adsorbs chlorine fast. Chloramine has to be catalytically decomposed, which needs a different carbon and considerably more contact time than a small cartridge can give it. So your filter is not broken, it is the wrong media for the job. What works is an under-sink reverse osmosis system, catalytic carbon under the sink or for the whole house, or both. Our Exchanger Pro RCC and Exchanger Elite RCC systems include catalytic carbon filtration that reduces chlorine, chloramine and ammonia at every tap. If you keep fish, chloramine matters more than taste: it is lethal to fish and does not dissipate by letting water stand out overnight, so a dechlorinator rated only for chlorine will not protect a tank.

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.
