About us
A Sunnyvale Water Treatment Team That Shows Its Work
Local technicians, measured readings and a spec sheet for every system. No commission, no mystery.

Where the spec sheet came from
Sunnyvale Water Filtration started with a frustration many valley homeowners will recognize. Ask three water companies for a quote and you get three glossy brochures, three very different prices and almost no numbers you can compare.
So we decided to quote the way people here evaluate everything else: with data. Measured readings at your tap. A system specified by flow rate and contact time. Certifications named. Media life and running cost estimated. One price. If the data says you do not need anything, we say so.
Today we install and service softeners, filters, reverse osmosis and well treatment across Santa Clara County, and every job still starts with a reading and ends with a second one.

What we are here to do
Give Sunnyvale households the water they want at the tap, specified clearly enough that they can judge the system for themselves, installed carefully and kept running.
We would rather explain why you do not need something than sell it to you. Over a decade of ownership, the honest answer is usually the cheaper one.
Six reasons customers stay with us
-
Measured, not assumed
Every visit starts with readings at your tap, and you keep them.
-
Chloramine expertise
We size carbon for the disinfectant valley utilities actually use, so it keeps working.
-
Running costs up front
Yearly cartridge, salt and water estimates sit next to the price on every quote.
-
Eichler and condo experience
Tight utility spaces and HOA rules are routine for us, not a problem.
-
Brand-neutral service
We repair and maintain most major brands, whoever installed them.
-
No commission
Technicians are paid for good work, not for upgrades, so the smaller option gets a fair hearing.
Standards we work to
We install components certified to the relevant NSF/ANSI standards, follow each manufacturer's installation and sanitization procedures, and pull permits where the local building department requires them.
- NSF/ANSI-certified filters, membranes and media
- Manufacturer-specified installation and startup
- Permits where Sunnyvale or county rules require them
- General liability coverage on every job
- Before-and-after readings recorded on every install
