Your water

What's really in your tap water here?

Homes across the Conejo Valley and Las Virgenes area drink imported State Water Project water, piped in from the Sierra. It's safe to sip, but it arrives very hard and disinfected with chloramine. You taste it, you see it on every fixture, and it quietly wears on your home.

ChloramineThe chlorine-and-ammonia disinfectant used in local water. Tougher than chlorine, and pitcher filters can't keep up.
Very hard waterAround 12+ grains per gallon, among California's hardest. Scales fixtures, spots glass, and dries skin.
Sediment & scaleMineral grit picked up over 470 miles of aqueduct and your home's aging pipes.
PFAS & moreTrace contaminants a simple pitcher filter can't reliably remove.
What we install

Two systems. Every drop in your home, perfected.

Local city water arrives very hard and disinfected with chloramine. The fix is two things: whole-home filtration at the main line, and reverse-osmosis drinking water at the kitchen. We size, install, and maintain both, so you never think about your water again.

1
Digital smart-valve headThe control valve on top runs everything automatically. A ceramic-disc design gives it a long, low-maintenance life, simple programming, and a 72-hour memory backup — it even cleans and regenerates the media on its own, so the system just works in the background.
2
Catalytic coconut-shell carbonThe first media layer. Catalytic carbon removes the chloramine, chlorine, odors, and PFAS-class contaminants that ordinary carbon and pitcher filters can't touch. Sustainably sourced from coconut shell and built to keep performing for years.
3
High-capacity softening resinUSA-made, 10% cross-linked resin pulls out the calcium and magnesium behind hard-water scale and spotting. It resists chlorine and oxidation for a long lifespan and delivers high-flow soft water with no drop in pressure.
4
Polishing gravel bedThe foundation beneath the media. It supports the bed, evens out water flow, and prevents channeling — so every gallon passes through the full depth of media and comes out consistently clean and soft.

Questions

Frequently asked

Do I really need a system if my water is "safe"?
City water is safe to drink, but "safe" doesn't mean clean or pleasant. Southern California water is hard and heavily chlorinated, which is why you see scale on fixtures and taste chlorine. A whole-home system removes what your utility legally leaves in.
What's the difference between a softener and a filter?
A softener removes the hard minerals (calcium and magnesium) that cause scale and spotting. A carbon filter removes chlorine, odors, and other contaminants that affect taste and health. Our whole-home systems do both in one setup.
What does reverse osmosis add?
Reverse osmosis (RO) is the final polish for your drinking water — bottled-quality water straight from your kitchen tap for drinking, coffee, and ice. We offer several RO systems; your water specialist will help you choose the right one for your home.
How often do filters need to be replaced?
Whole-home media lasts for years, not months. Sediment cartridges and RO membranes are changed on a simple schedule — and we handle it for you as part of ongoing service, so you never have to track it.
Will a system lower my water pressure?
No. We size every system to your home's flow, so you enjoy clean, soft water at full pressure — even in large homes with high demand.
How much does a system cost?
It depends on your home size, plumbing, and what your water test reveals — so we never quote blind. We start with a free in-home water test, then give you one honest, all-in price. Request your Quick Quote →
