Whole-home filtration
Point-of-entry systems that treat every tap in the house. Point-of-entry treatment is also plumbing protection: everything downstream, from the water heater to the shower valves, lives longer on conditioned water.

Local conditions
What San Jose does to its plumbing
Most of San Jose runs on some of the hardest municipal water in the Bay Area: the local water company's groundwater measures 11 to 26 grains per gallon, and its own FAQ connects that hardness to scale in water heaters and on fixtures.
The city's environmental review is just as blunt about the ground: much of the soil in San Jose is moderately to highly expansive, swelling and shrinking with the seasons in ways buried sewer laterals feel first.
The oldest neighborhoods, Willow Glen, Naglee Park, Japantown, commonly still drain through vitrified clay laterals laid in short mortared sections generations ago, and the Eichler tracts of the 1950s and 60s hide radiant-heat piping in their slabs that has outlived its design life.
This is also earthquake country by statute: California law requires every water heater to be strapped, the city checks it at inspection, and replacing one here takes a plumbing permit.
The hardness numbers in this area are high enough that softening is less about spot-free glasses and more about protecting the water heater and every valve in the house.
Right tool, right diagnosis
What we handle
We match the repair to what is actually happening inside the system.
Explore Water Filtration company-wide.
Water softening
Softeners sized to your household and water hardness. The difference shows up in weeks: soap lathers, glasses come out of the dishwasher clear, and the kettle stops growing chalk.
Drinking-water systems
Under-sink and reverse-osmosis options for the kitchen tap. Reverse osmosis under the kitchen sink is the practical answer for drinking and cooking water without treating the whole house.
Service and filter changes
We maintain what we install, plus most other brands.
Straight answers
What moves the price on water filtration
Filtration pricing depends on what is actually in your water and how much of the house you want treated, in that order.
Whole-home or point-of-use
A whole-home system treats every tap and protects the plumbing itself. An under-sink unit treats the water you drink for far less. Different jobs, different prices.
What the water test finds
Hardness, chlorine, taste and odor, iron, or sediment each call for different equipment. We test first so you buy treatment, not hardware.
Softener sizing
Softeners are sized by hardness grains and household water use. Undersized units regenerate constantly and die young.
Drain and space requirements
Softeners and backwashing filters need a drain and a bit of floor space; where that is available in your house affects the install.

Good questions, direct answers
Frequently asked questions
Do you offer water filtration near me in San Jose, CA?
We do. Elite Rooter covers San Jose, CA and the surrounding area from our office at 245 Kinney Drive, San Jose CA 95112. Book online or call (408) 664-9700.
Which filtration system do I need?
It depends on what's actually in your water. We start with what you're experiencing (taste, scale, staining) and recommend a system for that rather than the biggest unit on the truck.
Do I actually need a water softener here?
Check your shower head and kettle: if they grow white scale, your water is hard enough to be shortening the life of your water heater and fixtures. The measured hardness number decides the sizing; the scale you can see already answered the yes-or-no question.
