Cupertino Drinking Water
Are you living with the effects of hard water in Cupertino, CA? Are your forced to clean your clothes and dishes after they’ve already been washed? For example, do your clothes appear drab and your glassware cloudy? Do you see residue on your shower and bathtub that requires hard scrubbing and harsh chemicals to remove?
Or, does your skin feel tight and dry?
If you answered yes to any of these questions, you are likely suffering the ill effects of Cupertino’s consistently hard water.
Unfortunately, hard water can wreak havoc on many things in your home. It can make it harder to deep clean and polish your fixtures, and it can build up in your pipes like plaque in your arteries.
Hard-water build-up can shorten the life of appliances and keep them from operating at full potential. Hard water buildup in the hot water heater can raise your energy costs and can lead to expensive calls to a plumber.
How can I soften my water?
The good news? There is a solution! Your water can be softened safely and effectively through a water conditioning system, which will result in soft, filtered water on a 24/7 basis. De Anza Water Conditioning can help protect the investment you have made in your home and its pipes, water heater, appliances, and fixtures, as well as your tile, granite, marble, and glass surfaces. For over 40 years, De Anza Water Conditioning has specialized in eliminating water worries for clients around the Bay Area. As an authorized, independent dealer of Kinetico Water Systems, we have solved various and difficult water problems through water filters, water softeners, and reverse osmosis drinking water systems for residential and commercial customers.
De Anza Water Conditioning delivers an entire water treatment solution, which includes a leading reverse osmosis (RO) drinking water system. The Kinetico K5 Drinking System is certified to remove more contaminants than any other RO system on the market, while delivering up to 40 gallons of purified drinking water daily.
Kinetico Water Systems Kinetico systems are certified by the Water Quality Association (WQA) to assure the products meet industry standards for performance, capacity, and longevity.
For Cupertino residents and businesses, De Anza Water Conditioning can deliver a customized water treatment system that will meet your needs. When you install a Kinetico water softener, water filter, or reverse osmosis drinking water system, you will discover that your clothing and appliances last longer, your skin and hair are softer, dishes shinier, and, equally important, you will spend less time and money on repairs and maintenance.
How do I know this is a reputable water conditioning product?
We understand there are several options to consider when contemplating a water softening solution. However, at De Anza Water Conditioning, quality, effectiveness, and cost are all top priorities for us when advising our customers.
