Protect your estate's luxury fixtures, eliminate calcified scale, and extend the lifespan of high-efficiency tankless water heaters. Daso Plumbing installs whole-home water softeners, HALO 5 salt-free conditioners, and advanced leak defense throughout Los Altos and Los Altos Hills.
Water in Los Altos is predominantly supplied by California Water Service (Cal Water — Los Altos Suburban District) , while sections of Los Altos Hills are served by the Purissima Hills Water District .
The supply is a seasonal blend of imported surface water from the SFPUC Hetch Hetchy Reservoir and deep local groundwater wells . When local groundwater is actively pumped—especially during summer months, peak demand periods, or drought cycles—tap water hardness surges from moderate levels up to 12 to 18+ grains per gallon (200–310+ mg/L / ppm) , categorizing it as hard to very hard .
The high mineral content and chloramines in local municipal water directly degrade high-end plumbing architecture.
Calcium scale coats copper heat exchangers in Navien and Rinnai units, triggering overheating error codes, loud popping noises, and premature burnouts.
Matte black, unlacquered brass, and polished chrome finishes (Dornbracht, Waterworks) suffer chalky white spotting and permanent surface pitting.
Silica and magnesium bake onto frameless shower enclosures. Mineral crystals build up inside showerheads and aerators, restricting water pressure.
Miele dishwashers, steam ovens, and refrigerator ice valves seize up from calcified crust, drastically shortening luxury appliance operating lifespans.
Real systems installed by Daso crews on Peninsula properties.
High-efficiency demand-initiated ion-exchange systems that completely remove calcium and magnesium. Protects pipes, glassware, and appliances while using minimal salt and water.
Restorative chemical circulation flush to dissolve calcified scale inside your tankless water heater's copper or stainless steel heat exchanger, restoring efficiency and factory warranties.
Pair your water treatment with FloLogic automatic shutoff valves. We also replace scale-choked galvanized lines and pinhole-pitted copper pipes with Uponor PEX-A.
