Water Filtration & Treatment Corralitos — Built on What the Water Actually Contains
Water treatment starts with a test. Anyone who skips that step is selling, not solving.
The Problem With Buying Treatment Before Testing
Water filtration is the part of residential plumbing most prone to being sold rather than specified. A homeowner notices a problem — spots on glasses, scale on fixtures, a taste or smell — and gets pitched a system that may or may not address the actual cause. Sometimes it works. Often it doesn't.
We approach water treatment the way we approach every other plumbing job in Corralitos: measure first, specify second, install third. A water sample takes fifteen minutes to analyze and tells us exactly what's in your supply.
Only then do we discuss systems. Water softener installation, whole-home filtration, or targeted treatment each addresses different issues — and matching the right system to the right problem is the entire point of doing this work properly across Corralitos, CA.
💼 Built for Situations Like These
The Systems We Install and Service
Water Softener Installation & Sizing in Corralitos, CA
Hard water is the most common water quality issue. We size systems based on actual water hardness, household size, and usage patterns — not inventory.

Handles sediment, chlorine, and taste/odor issues at the point of entry. Selected based on flow rate, pressure loss, and contaminant profile.
Well Water Treatment & Iron Removal
We handle well water treatment including sediment filtration, iron removal, pH adjustment, and UV sterilization when needed. We also perform well pump repair and replacement.
Targeted Contaminant Removal Systems
Reverse osmosis for drinking water or specific media filters for nitrates, arsenic, heavy metals, and other targeted contaminants.

Resin bed cleaning, salt bridge removal, control valve replacement, and routine maintenance for all major brands.
Backflow Preventer Installation
Installation and annual testing for irrigation systems and code compliance across Corralitos.
Why Your Water Heater Is Dying Earlier Than It Should
Water heaters installed in Corralitos homes with untreated hard water typically last 60–70% as long as the same units installed in homes with proper water treatment. Hard water minerals precipitate as scale, acting as insulation and forcing the heater to work harder. The fix is either a water softener upstream or regular flushing.
⚙️ What Working With Us Feels Like
You'll get a water sample drawn on the first visit and test results before any system is specified. The recommendation will be based on your actual water, not a catalog. You'll see the test report, the system specifications, and a written scope before anything gets installed. Post-installation, you'll get clear maintenance instructions and a schedule.
What Corralitos Customers Say
"Well water with iron staining and sulfur smell. Two previous companies had recommended generic systems that didn't fully address the issues. All Service Plumbing Opa actually tested the water first and specified a three-stage system based on the results. Water is clear and odorless now."
— Franklin O.
"Water softener installed with clear documentation and a maintenance schedule. Everything explained in specifics, not sales talk."
— Delphine R.
"Reverse osmosis at the kitchen sink after their technician identified elevated contaminants in our test results. Installation was clean, the taste difference is noticeable."
— Octavian K.
