La Jolla receives the same extremely hard municipal water as the rest of San Diego — 169–270 mg/L of dissolved calcium and magnesium that deposits scale on every surface it touches. In La Jolla's high-end homes, the damage is particularly costly: scale buildup reduces water heater efficiency by up to 30%, shortens appliance lifespan by years, etches glass shower doors, stains natural stone surfaces, and deposits white crust on high-end fixtures. Beyond hardness, PFAS, manganese, and disinfection byproducts have been detected in the regional water supply at levels of concern.Homewerx designs custom filtration solutions based on lab testing results specific to your La Jolla home. A typical system combines whole-home water softening (salt-based or salt-free depending on your preferences and environmental concerns), whole-home carbon filtration for chlorine, chloramines, and VOCs, and a point-of-use reverse osmosis system at the kitchen tap for the highest level of drinking water purification. For homes with older plumbing, we add a whole-home sediment filter upstream to capture rust and particulates from deteriorating pipes. Every system is sized for your household's flow rate and usage patterns, professionally installed with proper bypass valves for maintenance access, and tested after installation to verify performance.

Water FiltrationHard water is not just an aesthetic annoyance — it's an expensive, ongoing problem. A Battelle Memorial Institute study found that water heaters operating on hard water lose up to 48% of their efficiency over their lifespan. Tankless water heaters, which are common in La Jolla's newer and renovated homes, are especially vulnerable — their narrow heat exchangers can clog with scale in as little as 2–3 years without treatment, requiring costly descaling or replacement. For La Jolla homeowners investing in premium fixtures, appliances, and finishes, water treatment is essential maintenance, not a luxury.
Softener salt replenishment is needed monthly. Sediment filter cartridges are replaced every 3–6 months. Carbon filter media lasts 3–5 years depending on usage. RO membranes last 2–3 years with pre-filters changed every 6–12 months. We provide a maintenance schedule tailored to your system and recommend annual water retesting to confirm performance.
