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.
Water Filtration
Water Filtration in San Jose, CA
Better-tasting water and less scale on everything the water touches. Elite Rooter installs and services whole-home water filtration and treatment systems in San Jose, CA, matched to your actual water instead of a one-size-fits-all pitch.
Common signs
Signs you may need water filtration
One symptom can be minor. Several together usually point to a larger issue.
- Chlorine taste or smell in tap water
- Scale buildup on fixtures and appliances
- Spotty dishes and stiff laundry
- Dry skin and hair after showering
- You're buying bottled water at home
What we handle
We match the repair to what is actually happening inside the system.
Explore Water Filtration company-wide.
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.
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.
Pricing factors
Water Filtration Costs
Filtration pricing depends on what is actually in your water and how much of the house you want treated, in that order.
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.

Google review · 2026-08-22View San Jose Google Business ProfileZac was incredible, trustworthy, and honest with his assessment of our kitchen sink repair. I called several plumbers and all of them quoted me astronomical prices for a relatively simple and small job. Not only was Elite Rooter the best value option, but Zac also provided some post-repair suggestions as well. Would recommend to anyone needing plumbing repairs.

Questions before booking
Frequently asked questions
Do you offer water filtration in San Jose?
Coverage depends on the exact address. Share the San Jose service address when you call or book so the team can check it.
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.
