Los Angeles tap water is very hard, ranging from 12–22 GPG depending on your neighborhood. The San Fernando Valley, which blends more local groundwater, runs 18–22 GPG — the hardest in the county. West LA and Westside areas served primarily by Colorado River MWD water run 15–18 GPG. Beach cities like Santa Monica and Malibu are relatively softer at 12–16 GPG. All LA districts exceed the national average of 10 GPG and the "very hard" threshold of 10.5 GPG. Call us with your zip code and we'll look up your specific district reading from the LADWP water quality report.

Yes to both. The Environmental Working Group's tap water database has found chromium-6 in LADWP water above EWG's health guideline of 0.02 ppb. Chromium-6 enters the water supply from California's geology and Colorado River tributaries. PFAS "forever chemicals" have been confirmed in San Fernando Valley groundwater from EPA Superfund sites near Burbank, Van Nuys, and former Lockheed/Rocketdyne industrial properties. LADWP blends this groundwater into its distribution system. A 5-stage reverse osmosis system removes 95%+ of chromium-6 and PFAS at the tap; a whole-house PFAS filter protects every fixture.

Yes. Santa Clarita — the largest city in LA County — prohibits conventional salt-based water softeners due to its water recycling infrastructure. Salt discharge from softener regeneration raises the salinity of recycled water beyond acceptable limits for agricultural and landscape use. Other LA County communities with recycled water programs may have similar restrictions. If you're in Santa Clarita or are unsure about your city's rules, call us at 785-661-2241 before ordering. We'll confirm your status and direct you to the right salt-free water conditioner if needed.

Sizing depends on your household size and your specific district's hardness. For most San Fernando Valley, East LA, and central LA households with 16–22 GPG water: a 64,000-grain system handles 3–5 people comfortably. For Westside and South Bay homes at 14–18 GPG with 2–4 people, a 48,000-grain system is typically sufficient. For Santa Monica and beach cities at 12–16 GPG, a 40,000-grain system may suffice. Call us with your zip code and household size and we'll calculate the exact capacity you need.

LADWP uses chloramine disinfection — a combination of chlorine and ammonia — which has a stronger, longer-lasting chemical taste than plain chlorine. Standard activated carbon filters remove chlorine effectively but significantly underperform against chloramines. For LA water, you need either a catalytic carbon filter (which uses a specially processed carbon media that reacts with chloramines) or a water conditioner with KDF media (like the AFW City-Pro). Adding an RO system at the kitchen tap will remove any remaining taste and chloramine byproducts from your drinking water.

Yes — they do different jobs. A water softener removes calcium and magnesium (the minerals that cause scale) via ion exchange. It does not remove chromium-6, PFAS, lead, nitrates, chloramines, or other chemical contaminants from your drinking water. An RO system installed under your kitchen sink removes 95–99% of all of those contaminants at the point of use — your drinking and cooking tap. For LA's full contamination profile, both systems working together provide complete protection: the softener protects your appliances and plumbing, the RO system protects what you put in your body.

LA homeowners typically save around $600 per year in combined costs after installing a water softener. That includes: dramatically reduced soap, shampoo, and detergent consumption (soft water requires 50–75% less); extended appliance lifespan (water heaters last 12–15 years softened vs. 5–7 years with 18 GPG water); fewer plumbing calls; and elimination of scale-related repair costs. Most properly sized softener systems pay for themselves within 2–3 years for a typical LA household at valley hardness levels.

Yes — we ship free to all Los Angeles neighborhoods on orders over $100. That includes all LADWP service areas: San Fernando Valley, Westside, East LA, Hollywood, Mid-City, South Bay, and all surrounding communities in LA County. Salt-free water conditioner options are available for Santa Clarita and any other restricted communities. We've been serving LA homeowners since 1998.
