Reverse Osmosis Drinking Water in San Pedro, CA

Reverse osmosis is the only residential filtration method that removes dissolved solids — fluoride, residual lead from pre-1986 plumbing, nitrates, pesticides, and the sodium added by ion-exchange softeners. A standard under-sink RO system is a four- or five-stage assembly (sediment, carbon pre-filter, RO membrane, post-carbon, optional remineralization) with a pressurized storage tank and a dedicated kitchen faucet. We size production capacity to household demand and install permit-free in 2–3 hours.

Reverse osmosis is a kitchen-only premium tier that addresses the part of South Bay water whole-home carbon filtration can't touch — total dissolved solids. San Pedro sits on LADWP municipal supply (Los Angeles Department of Water and Power supplies San Pedro with imports averaging 8–10 grains-per-gallon. Hardness is moderate; the larger water-side issue is age-related galvanized supply line corrosion, which has been the dominant complaint category for years), which delivers safe but mineral-rich water that varies block-by-block. RO installation at a San Pedro kitchen sink typically rejects 94–99% of TDS, producing drinking-water-quality flow at a dedicated faucet without the bottled-water cost and plastic waste. Most San Pedro households that install RO are replacing $40–$80 a month in bottled water for drinking, cooking, ice, and coffee — payback runs 12–18 months.
