Sunnyvale Water Filtration Notes and Explainers
What the numbers on a water report mean, and what to do about them.

Why we write these
A lot of water treatment content is written to sell one specific product. These articles are written by the people who measure and install, and they lean on numbers wherever numbers exist.
Expect explainers on chloramine and how carbon removes it, what hardness readings mean for appliances, how to read a water quality report, RO efficiency, softener salt use, tankless heater scale and well water in the foothills.
Where we quote numbers, we say where they came from and what range is typical, so you can compare them with your own water report. Every article should be useful even if you never call us. When something is a reasonable DIY job, we will say so and explain how. When it is not, we will explain why, and what a fair price looks like so you can compare quotes.
Got a water question we have not covered?
Ask it on the phone. Good questions become articles.
Answered by technicians, not a sales script.
