I needed a whole house water system because of a recent plumbing remodel, new faucets that needed to be protected from hard water that leaves corrosion, wanting to have good tasting drinking water from every faucet and healthy water to shower with. After much research of different systems, I decided to call Kevin at One Water Systems for a consultation and estimate. He came to our home and gave me a thorough education on filtration systems, all my questions were answered and we got information on what size of tank and installation would be needed for our home. I continued to do research and had a consultation with another company and after careful comparison, I decide the One Water System was for us. I drove to the offices/showroom in the San Diego area and again talked to Kevin about a few additional questions I had. We then settled on the system we needed and negotiated a good and fair price with some nice discounts, including free installation. The installation was done a week later by Juan, very professional and knowledgeable with all aspects of the system. I would highly recommend that if you have an old water pressure valve that you replace it at the time you do the new install. We had to call a week later because the valve gave out, even though it had registered a safe water pressure at the time of install. Juan came out again and installed a new pressure valve and corrected a small leak from one of the joints (probably caused by the valve that failed). Bottom line is everything got done to my satisfaction and we have had the system in place for two months. Love the taste of the water and the feel of the water when washing your hands or taking a shower, love the reduction in detergents also. Overall the investment is one of the best thing we’ve done for our home. I liked the personal touch of Kevin calling a few weeks later to check on our experience and satisfaction. We have already referred a couple of people to One Water Systems due to our overall satisfaction! Thank You Kevin and Juan for a great job and for your outstanding customer service.

Vic V. - San Marcos, CA

I used the services of One Water Systems for a water system, about a month ago. They were very professional and did a great job. I liked their services and will use the same in futu

Fred G. - Oceanside, CA

Now, a month later, we’re even more pleased with the system. All promises made have been fulfilled.

It is so wonderful to have pure drinking water from every faucet in the house. No more bottled water or filters for the refrigerator.

You can “feel” the softness when you shower. For showering and, especially, for laundry, less soap is necessary. Laundry comes out much cleaner looking.

At first we had spotted glasses coming out of the dishwasher but Finish JetDry has taken care of that. Our very old dishwasher now does a much better job.

We’ve always used Clorox tabs in the toilets and such are still necessary, probably even more so. But now there no longer is a hard-water ring in the toilets. No special cleanup necessary.

All in all, we think we’ve made a terrific investment.

Robert K. - San Diego, CA

The difference is AMAZING- skin is not dry, hair is tamer (a miracle for my dry curly hair!), grandbaby’s eczema getting better. Tap Water tastes so much better. And if that’s not enough…the best part: no more discolored water filling up our bathtubs. Awesome! They said it would take a couple of weeks for the calcium build up to clean up- not! Our shower heads are already flowing like they did when they were new. Thanks Kevin…

Sandra M. - Bonita, CA

Kevin, the owner, spent a lot of time with me explaining how the system works. Juan did a good job of installing the water system (neatly done) and then showing me the difference between the water I had before and water using the One Water System. Amazing! Everything went very smoothly. I must add that it is very important for me to be dealing with people who are kind and helpful, people who enjoy what they are doing. This I found with those who work for One Water System. Need a water system? I highly recommend this company. The best.

Eric S. - San Marcos, CA

I like having clean, tasting water..it’s easier to clean things. The ads are good, that’s how I found out about One Water Systems. The annual inspections are a great idea, too! I feel better knowing I don’t have to figure out if it works or not! I definitely recommend to others..Our rashes have cleared up, skin and hair looks better. I Love saving money on bottled water..(plus holding a glass under the sink weighs a lot less than a 5 gallon jug!)…I’ve been VERY happy with this system.

Edna A. - Del Mar, CA

I researched four different types of whole house water systems. Obviously the systems were not the same but, of course, they all may claim to sell their product. I finally chose Kevin Worsfold’s “One Water Systems”. He was the only one who didn’t bash other companies and knew more than all of them about water, pipes, appliances, clothes and, of course, the system itself.

Jean S. - Laguna Hills, CA

After experiencing a not so successful system -I found One Water. It’s been working beautifully and have experienced absolutely no issues. I could not be more pleased and recommend this system without hesitation to any home looking to replace or upgrade their system. Excellent!

Madeline C. - Del Mar, CA

Kevin explained the system will and answered all our concerns. Juan the plumber was professional, on time and great personality, explaining the system while installing it.

Eugene S. - Escondido, CA

Bob S. - Poway, CA

All parties involved were professional and accommodating. From beginning to end the process and installation of the One Water whole house water filtration system went very smoothly. All parties involved were professional and accommodating. In fact, we were very impressed with the plumber’s innovative ability to install the system in a small space.

Myrtle M. - Oceanside, CA

We are very happy with this product – and the service we received was phenomenal!!! From the scheduling, the sales person and the installer!!! All very professional and very nice people. Thank you

Miguel K - San Diego, CA

It’s been almost more than two years having One Water system and we are very happy. It is none to less maintenance required system which is the most part we like. We would strongly recommend to any one who is thinking to have water filter system.

Dinesh P. -Carlsbad, CA

I’ve had my One Water system for a few months now and I love how much better the water tastes. There used to be a reverse osmosis filtration system and a water softener and this is definitely superior. Not to mention better for my Keurig coffee machine! I also like that I can use the water for my plants without worrying about the sodium of the old softener. Thank you for having such an excellent system!

Jake & Patty K. -San Diego, CA

Great tasting water and great service too…a yearly inspection of the system, ph and chlorine levels, water pressure and a basic check of water usage (per how many people live in the house) with any adjustment needed for the system “wash”….well worth the investment for our family!

Dorian V. -Carlsbad, CA

Best water ever for our own taps! SoCal water must be one of the worst for taste. Since we installed our OneWater system we now enjoy clean fresh tasting water at every tap. Best investment we ever made. We have owned it now for close to 6 years and it is one purchase we never regretted.

Gary P. -El Cajon, CA

We’ve had our system 5 years now. Completely satisfied. The system does exactly as advertised. A rep. comes out each year to check operation at no expense. I lived 60 years in Portland so I know good water. This compares very favorably.

Brock S. -Fallbrook, CA

They installed an electric water conditioning system which doesn’t require the use of salt. Everything has been going well. It was a bit pricey compared to a regular water softener, but it has significant advantages. They did a great job with the installation and have been servicing the system like clockwork. We’re very happy with the system and would highly recommend the company.

Matthew P. -Oceanside, CA

Purchased and installed a whole-house water purification system.
CEO/owner visited the home, provided info on how their company performed, explained cost/payment options/service followup, etc. (I had already done extensive research on their company.) The installer was quick, professional, very sociable and he didn’t screw anything up with the installation.

John & Pam H. -San Marcos, CA

A whole house water filtration system was installed.
Every individual I dealt with was a true professional. The owner Kevin made sure I had exactly what I needed. Jenn was great handling my delays and Juan the installer was on time, polite and really did a super clean installation. Love my “new water”.

Rudy N. -Carlsbad, CA

Just a quick note to say that the system is performing nicely. I love the water taste and feel on the skin! thanks!

Alexandra L.-San Diego

We are very satisfied with our water filtration…The ads are always changing…are eye catching.  Had 1st annual inspection, good deal!  Extremely happy we got the system.

Charles N.- San Diego

For you one liners:  noteworthy from A to Z!

For the rest:  Kevin and his staff at One Water Systems are awesome.  Many months ago I called One Water to ask some questions about my existing water softener.  The owner (Kevin) not only answered the phone and my questions, but volunteered to come out and give me a free water and air test.

He arrived promptly and analyzed my water.  He educated me about the problems with a water softening system that used salt.  He also educated me about the reverse osmosis system that I also had.  He then analyzed my air quality both inside and outside (around) my house.

Next came the recommendations.  He never tried to sell me anything or use those high pressure sales techniques on me.  His passion for what he was doing, the systems that he sells and believes in sold me on getting some of what he had to offer.

I then agreed to purchase both the air and water purification systems.  However, my budget was a bit tight and although I had agreed to purchase the systems and had a scheduled install date, Kevin put my order on hold until I was ready!  WHO DOES THAT???

Anyway, fast forward 3 months and as of today, I am the proud owner of a One Water purification system as well as a Healthway pure air system!  The installer was awesome as well, he knew his stuff and was very thoughtful and thorough.

I don’t want to steal Kevin’s thunder by telling you all the specs, and features of these systems, but my quality of life is already improving.  My shower was awesome, no residue.  I tested the water tonight with some fish strips and it is right in the middle, not to low or high on the PH level.  I could go on and on, but let me close by saying, if you have any health issues, especially regarding breathing, allergies or skin issues, then you should give One Water Systems a call!

Thank you Kevin and One Water Systems for your kindness, knowledge, passion, patience and professionalism!  5 stars all the way!!!!!

As perfect as it gets!

Drew B.- Oceanside, CA

The main reason for looking for a water treatment device was the hard water and having drinkable water.  Our presentation was informative and all our our questions were addressed.  The installer arrived on time and was excellent and he explained what to expect in the next few days.

I recently purchased a home that had a One Water Systems previously installed. What prompted me to purchase the home out of all the homes I had seen were the clean faucets and no build up. I asked the previous owner what kind of filtration was installed and they said, “We have a One Water”.

I’m very happy with the decision I made! Thank you One Water Systems.

R. E.

I researched four different types of whole house water systems from $200 to $4000. Obviously the systems were not the same but, of course, they all may claims to sell their product.

I finally chose Kevin Worsfold’s “One Water System”.. He was the only one who didn’t bash other companies and knew more than all of them about water, pipes, appliances, clothes and, of course, the system itself.

It’s not a water softener…

L.M.

The main reason I was looking for a water treatment device was the hard water and my old system needed replacing. The One Water Systems representative was informative, very detailed and thorough and all of my questions were addressed.

I am very happy with the One Water System. My dishes are no longer spotting, the water tastes great and I’m using less soap.

Everything seems cleaner!

I am doing the HCG Diet and I read that in order to mazimize the weight loss it is advised to get a water filtration system and that tap water can either make you fat or at the very least not allow you to lose weight.

There are many bad chemicals in water and once I started the HCG diet and got One Water System’s Whole House Water Filtration System the pounds just started to melt off. I have great tasting water and a great looking body and I feel so much healthier.

Thanks One Water!

Sarah Westerman

We bought One Water Systems initially to have accessibility to safe and clean normal water. Previously we had tried home water bottle service or buying big cases of water at Costco. Once we started having kids and saw the importance of good water and how fast we were going through it we talked to our pediatrician explained the importance of filtered water and explained that no bottled water products even come close to the quality and safety of the water from a whole house water filtration system. We had seen the whole house water filtration systems at the Del Mar fair but hadn’t paid to much attention to them until our station in life changed along with our priorities.

We could now get filtered water from every faucet in the house. we still had flyers from a recent homeshow and called out One Water Systems. We were so impressed with the product and the product knowledge that the rep had and the price we just couldn’t say no. Especially when we thought about our chidren’s well being. You can’t put a price on that. We have now had a water filtration system from One Water Systems for just over three years and the water still tastes amazing and every time I look at my kids who are now tall enough to reach the tap water on their own and see them pour themselves a glass of water it just reassures my husband and I that we made the right decision.

We recommend One Water Systems to to anyone wanting better health for themselves and their families.

I had a carbon filtration from a “large” company I assumed would be reputable, but their customer service was non-existent, & I found out their warranty did not include “usable parts”. When your advertisement showed better technology & service, I gave up theirs for yours & I”m thankful I did because not only did you help me with my concerns, your people showed up on time!!
