About us

A Daly City Water Team That Knows These Houses

Local, small, and used to working in garages that were built for one car and a water heater.

How we got here

Daly City Water Filtration started with neighbors asking the same two questions. Why does our water look rusty sometimes? And why does the shower smell like a swimming pool?

The answers were usually simple: original galvanized pipes and chloramine in the regional supply. But the quotes people were getting did not fit their homes. Big whole-house systems that would not fit in a Westlake garage, softeners for water that was already soft, and very little honesty about what a filter can and cannot do for old pipes.

So we started fitting the right equipment to the houses people actually live in here. Today we test, install and service water treatment across the north Peninsula, and we still begin every visit by looking at the pipes.

What we care about

Clean, good-tasting water in Daly City homes, from equipment that fits the house, installed carefully and kept running.

We would rather tell you the truth about your plumbing than sell you something that only hides the problem.

Six reasons neighbors stick with us

  • We know older homes

    Galvanized lines, garages at street level and laundry by the water heater are everyday work for us.

  • Honest about plumbing

    If the pipes need replacing, you will hear it from us first.

  • Chloramine handled right

    Catalytic carbon sized for the regional water, so the taste stays gone.

  • No softener habit

    Daly City water is usually soft. We do not sell what you do not need.

  • Any brand serviced

    We look after systems other companies installed.

  • A small, steady team

    The same people answer the phone and do the work.

How we work

We install filters and membranes certified to the relevant NSF/ANSI standards, follow manufacturer installation and sanitization instructions, use certified laboratories for lead and bacteria testing, and pull permits where local rules require them.

  • NSF/ANSI-certified filters, membranes and media
  • Certified laboratories for lab testing
  • Permits where Daly City or county rules require them
  • General liability coverage on every job
  • Written readings and a filter schedule left after every install
