The San Mateo Water Filtration Blog
Short, practical reads about the water on the Peninsula and the systems that treat it.
Why We Write These
Most water advice online is written to sell a product. Ours is written for the questions we answer in San Mateo kitchens every week: why the tap water tastes like a pool, whether a softener is worth it on the Peninsula, what to do about an old galvanized line, and how coastside wells differ from city water.
Each article is short, specific to this area and honest about when you don't need to buy anything. If something here sounds like your house, a reading is the next step.
Expect topics like reading a Cal Water quality report without a chemistry degree, what chloramine does to rubber washers and aquarium fish, why an RO membrane lasts longer on soft Peninsula water, and how to tell sediment from rust when the morning glass looks off. Coastside well owners will find pieces on shock chlorination, UV lamp timing and when a certified lab sample is worth the trip. New pieces go up as questions come in from San Mateo, Burlingame, Foster City and the coast.
Rather Just Ask?
Skip the reading list. Describe what you're seeing or tasting and we'll tell you what it probably is, in a few minutes on the phone. If it sounds like something a reading would settle, we'll offer a time on that week's route.
No pitch, just an answer. Serving San Mateo County.
