Home Water Softeners to Solve Hard Water Problems

Hard water can cause all sorts of problems for homeowners . It causes limescale that clogs your pipes and appliances, prevents soap and detergent from working effectively, makes your skin and hair seem dull and lifeless, causes unsightly stains and generally isn’t good for your health.

If you live in a hard water area, as many Americans do, a water softener system for house use will solve all your problems. But before you install one, you need to know the extent of the problems you have and how best to resolve them.

Benefits of Installing a Whole House Water Softener System

Unlike a pitcher filter that only delivers a small quantity of softened water for drinking, a whole-house residential water softener for home use covers all the water you consume. It provides:

better tasting water for drinking and cooking

pipes and appliances that aren’t clogged by limescale, lengthening their lives and preventing problems

a reduction in the need for bottled water, which helps the environment by reducing the amount of plastic going to landfill

increased effectiveness of soaps and detergents so you save money by using less (up to 70% less according to some studies) as well as getting cleaner clothes, crockery and cutlery

fewer unsightly stains caused by limescale

shinier hair and softer skin

improved health, especially for those with skin conditions such as eczema and psoriasis that can be aggravated by hard water

reduced energy bills since soft water is easier and quicker to heat than hard water which contains many dissolved minerals.

The Best Home Water Softeners System for You

Water softeners for home work by replacing with sodium ions the calcium and magnesium ions that cause hard water. There are some concerns that the sodium salts flushed out of a water softener can contaminate groundwater and be harmful to the environment. However, the average family water softener only regenerates and flushes two or three times each week so the effect is minimal.

Concerns have, however, resulted in several areas banning or restricting the use of salt-based water softeners. If you’re affected by this, you can instead install a water conditioner equipment that requires no chemicals or anything else to be added to the process but instead crystallizes the minerals that cause hardness so that they solidify and don’t cause limescale to form. Although such a device doesn’t soften water, it does reduce its effects and can be very effective against water that isn’t too hard.

As one of the best water conditioning service company, we can advise you on the best and most relevant system for you, especially after conducting a test of your water to assess its hardness and any other problems. Installing a combination of water filters and a Kinetico water softener will ensure your water is as soft and pure as it can be. That will improve your health, increase your enjoyment of food and drinks, enhance your appearance, prevent appliance and plumbing problems and save you money on daily costs. So it’s something you really can’t afford to delay doing.

Kinetico Premier Series

Kinetico Premier Series® non-electric water softeners are powered by moving water and have multiple tanks for continuous soft water, even during regeneration. These high-flow systems are comprised of multiple tanks, so you’ll have a continuous supply of soft, clean water.

Kinetico Premier Series Highlights

  • Generous Flow Rates

    Designed for homes with larger plumbing and high water use, Premier Series softeners deliver generous flow rates without forfeiting water softness.

  • On-Demand Regeneration

    One tank is always in service while the other tank is either on standby or regenerating. Premier Series systems regenerate at any time of the day or night to ensure you will always have a supply of soft water. So if you have a house full of guests or are washing multiple loads of laundry, you’ll never run out of soft water.

  • Premier Series XP

    Our patent-pending XP feature allows more precise system calibration to your home’s specific water conditions for optimum efficiency, operational cost savings and waste reduction. It’s like having a water softener that’s a custom-fit for your home.

  • Kinetico Premier Series S650 XP, S650 OD XP, Q850 XP and Q850 OD XP

    The models listed above are the world’s most efficient water softeners, providing more soft water from each bag of salt than any other water softener you can buy.  Some brands may say they have the most efficient softener, but Kinetico has the data to prove it.

    Our claim is based on independent testing done by the Water Quality Association (WQA) per NSF/ANSI Standard 44, an industry-accepted efficiency rating measuring the amount of hardness removed per pound of salt used.

Kinetico Signature Series

Kinetico Signature Series® non-electric, dual tank water softeners provide soft water all the time, at an economical price.

Signature Series Highlights

  • Twin Tanks

    Kinetico Signature Series water softeners are modeled after our original twin tank, non-electric water softeners that have been solving the water problems for millions of people worldwide for decades.

  • Non-Electric Operation

    Powered by water flow (kinetic energy) instead of electricity, there are no electrical components to repair or replace.  You can count on Signature Series water softeners to solve your hard water and soluble iron problems without creating new ones.

  • On-Demand

    The beauty of a Signature Series water softener is its ability to monitor your water use and regenerate (clean) itself only when needed. If you use a lot of water, your water softener will regenerate more, or it may not regenerate for several days if water usage is low.  This efficient approach saves salt, water, money and guesswork.

  • Softwater, Countercurrent Regeneration

    Signature Series water softeners regenerate using soft water. With soft water regeneration, your system will work better and last longer.

Honestly, over the years of calling De Anza Water for service was never a headache.  They had always been responsive and came on time and when they said they would.  There were never any surprises.

When I sold my house recently, I needed to fix the Reverse Osmosis unit because of a leak which was due to the housing of the unit, no big deal, really.  I worked with Jennifer Administrative Assistant where she never ever left me high and dry.  She responded very quickly, was completely behind what she said, and she helped schedule an appointment with the new owner.  She is the best!!!

The unit is fixed and working properly! Thanks so much for the great service over the years!

I was looking for a good water softener for a long time. I finally had enough with hard water for water stains and hair loss. So I started shopping around again and read some good reviews about Kinetico. DeAnza was very knowledgeable about water softener and understood my concerns about using soft water for irrigation and proposed a perfect solution to install another irrigation pipe directly to my backyard. Considering all the unique features of Kinetico and my concern was resolved, I hired De Anza water to install a refurbished system.

The system looked very nice in my garage. They showed me how to by-pass the water softener to clean the water filter and also mentioned that where the system might leak. So far the system is working perfectly and I cannot be happier with how my water now feels.

Our family chose De Anza Water Conditioning for many reasons.  They were extremely responsive to my online Yelp quote request, super friendly on the phone, and they carry a very high end product.  They are an authorized dealer of Kinetico which is basically a 2 for 1 product you get soft water all the time and all of your entire homes water is filtered.

Installation was super easy and fast.  Plumbing was routed very efficiently and clean looking.  It took only a couple of hours to finish the install. It has been a little over a week now and we can definitely taste, feel, and see a huge difference. Soap is super bubbly, water taste is amazing, our hair is softer more clean feeling.  We are really excited about our water quality now.  In honesty I was not expecting this big of a difference.  We don’t like to mess around drinking and showering in poor quality water.  Thank you De Anza.

Requested De Anza Water to service our water softener and change out the whole house filter, and reverse osmosis water filters.  When our tech arrived, he suggested the possibility of replacing our 20 year old water softer. Technology has improved the softener to use 30% less water, 30% less salt, and less energy. Sounded like a win to us. We’re glad we did it! I’ve been with De Anza Water conditioning for 20 years. We always find them to be 5 stars for us.

I highly recommend De Anza Water to anyone!! Great customer service!!!

We just had to place a service call (for something we caused… we still love the Kinetico system!!). Making the appointment was easy. We really appreciate that we got a message when our technician was on his way. It had his name, photo and a link to see how far away they were and when they would arrive.

They were so thorough with everything and respectful of our property!! And provided helpful info for extending the life of the system.

I was very happy with the service and support from De Anza Water conditioning. Their package and service was not the least expensive that I considered but I was impressed by the long term support they provide their customers. I had a lot of questions and our sales person Tam was patient and addressed all my concerns. Installation went smoothly and I am SO happy with the system and the quality of our water.  I highly recommend De Anza Water.

Flow pressure of water is not compromised either, while ensuring great quality filtration and softening. Equipment does not use electricity either, compared to other brands that use electricity. Maintenance is not required every year for softener compared to competitors. This is a high quality product. Although expensive than other cheap brands, quality speaks for itself. In long run that additional expense does pay off.

I just LOVE these folks!  They have serviced my water softener for the better part of the last 15 years:  they are always on time, they are always thorough, the price is always what they said it would be when we scheduled the appointment, and they are always professional.  Patrick came out a couple weeks ago to change the carbon.  When he was doing it, he noticed a couple problems with the water softener and so he just fixed them without any extra charge.

Anna S.

We have been drinking their water since moved to California. we didn’t like the hard water and the quality, found De Anza Water and learnt that we could get water softener and filtered drinking water installed, we decided to go this path.

We have been a client for 10 years for water softener with De Anza and very happy.  After doing a lot of research, we had Kinetico RO put in for drinking water and LOVE the system.  It is amazing.  John came out to our house for consultation and we really learned a lot from him.  The water quality Exceeded our expectation.  Mike installed the unit and he was superb and we thank him for his amazing work.  Thank you John, Lynne, Mike, Judy and Ian.  The customer service is great.  If you are really looking to get an RO system, this is it.  It is expensive but WORTH IT. Every time I drink it, I think of John and how passionate he is about his work and company.
