Protect your high-end appliances, water heaters, and plumbing fixtures from damaging mineral scale, chlorine, and heavy metals. We design and install high-capacity ion-exchange softeners, catalytic carbon media tanks, and reverse osmosis drinking water systems.
While tap water across the San Francisco Peninsula originating from the Hetch Hetchy reservoir is relatively pure, local municipal water districts regularly blend in treated surface runoff and activate mineral-dense groundwater standby wells during peak summer months and drought conditions. In cities like Mountain View, San Jose, Santa Clara, Sunnyvale, and portions of San Mateo County, water hardness climbs between 7 and 18+ grains per gallon (GPG)—classifying it as moderately hard to very hard.
Dissolved calcium and magnesium carbonate precipitate out of hard water whenever it is heated, forming rock-hard calcite scale inside tankless heat exchangers, boiler circulation loops, washing machines, and dishwashers. Over time, mineral scale restricts water flow, reduces heating efficiency by up to 25%, and causes premature appliance burnouts. Furthermore, municipal disinfection chemicals (chlorine and chloramines) dry out skin and hair and degrade internal rubber plumbing gaskets.
Daso Plumbing engineers custom water treatment systems tailored to your home’s exact water chemistry and square footage. From traditional high-efficiency ion-exchange softeners that produce spot-free glassware and luxurious soft showers, to eco-friendly salt-free conditioners (like HALO 5) and multi-stage sub-sink Reverse Osmosis (RO) drinking stations, we ensure every drop entering your property is clean, pure, and fixture-safe.
Commercial and residential digital metered water softeners that chemically remove calcium and magnesium ions on demand.
Eco-friendly Template-Assisted Crystallization (TAC) systems that condition hard minerals without salt bags, electricity, or brine wastewater.
Multi-stage central carbon media filtration tanks that strip offensive chlorine, chloramines, VOCs, pesticides, and unpleasant odors.
Multi-stage under-sink reverse osmosis purification units with dedicated luxury designer faucets and refrigerator ice-maker hookups.
We create custom mechanical plumbing loops with brass 3-valve bypass assemblies to integrate conditioners seamlessly into main service lines.
High-capacity duplex alternating water conditioning plants engineered for restaurants, breweries, hotels, and athletic facilities.
