Have used them for close to 10 years. They installed and service our RO system and soft water system. Reliable and trustworthy.

There is a reason #IntegrityWaterSolutions has all Five Star Reviews. My RO went down at Christmas they suffered a break in at their warehouse and were exceptionally busy. You're wondering what happened? the owner Brian came to my house at 5pm on Sunday and handled the challenge. This is the epitome of customer service and I can assure you that #Integrity WaterSolution rocks and they are the best Thank you Brian best in 2026 read more

Brian is a very kind and caring man. He is very professional. I called for an appointment and the response was very fast. They did a great job, quick and clean. I recommend Integrity Water Solutions very highly. I will not use anyone else. read more

Working with Michelle at Integrity Water Solutions is what any customer service experience should be like. She is extremely responsive, efficient, friendly and deeply empathetic. If it weren't for both her and her husband's professionalism, I would have given less stars for this review. We had a soft water system and RO system installed at our new home and everything went smoothly from scheduling to pre-site up until the installers showed up. My husband, unfortunately, had to deal with some unprofessionalism and rudeness from one of the installers and I had to report it to Michelle immediately. Luckily, she is a "boss" of a woman and was able to reprimand her employee appropriately. Months later, we are still enjoying the smoothest showers we've ever taken and the cleanest water we've ever drank out of the sink or fridge. I am glad they stand by their name. It's one of the reasons we even hired them. read more

We hired Integrity to install a water softener in our home, based on a neighbor's recommendation. We are really happy with their work and also the price. Plus they gave a $100 discount because we were referred by a neighbor. Once we gave them the green light they were able to work us into their schedule very quickly. We really like the quality of the "soft water" and it seems to be helping improve my skin. I only wish we had gotten the water softener installed years ago, the water in Tempe is SO hard. read more

Made an apt a week and a half out for a repair on our softener. Technician never showed up or called, I called 2 more times, and they didnt showed up for the next apt. Less then one star if I could read more

Integrity installed a 56k grain water softener, replaced the main water shutoff and water pressure regulator in our home on 2/18. The estimated time of work was projected around four to five hours but the team of two got it done in three. The installation could not have gone better. The team reviewed the statement of work and then started prepping for the job. I came out a few times to see how they were doing but other than that left them alone. After the installation and while reviewing the work I was impressed by the neatness and thought-out manner of the installation. Clean and neat. I would recommend this company to my friends and family and will highly consider them in the future for any plumbing needs. read more

These folks have been servicing my water softener for years and I'm quite happy. I was especially pleased when Amy, their scheduler, called to let me know the technician was running late and would the new appointment time work for me. The technician installed a new timer and all is operational. Extra benefit: these folks don't automatically try to sell a new equipment when it's not necessary and I very much appreciate their customer-oriented approach. Next time my softener resin beads need replacement, I'll opt for a completely new softener and I know who to call. read more

I live in an apartment and my tap water is horrible. I was tired of hauling gallons of bottled water to cook and drink. I wasn't sure if I was able to get an RO system at my place, but after talking with Michelle at IWS, it turns out I can as long as I had a side faucet punch out on my kitchen sink. IWS was great to work with. I was able to get a good quote on the unit and installation. They came out within a few days. Technician was on time, professional, quick, and took the time to explain to me how the RO works. The RO system installs as a stand alone device. It doesn't require any electricity (except for a battery that operates the moisture sensor). You can take the system with you if you move out of the apt. It connects to your cold water valve in, then filters through, and stores in a 3.2 gallon tank. The tank continuously fills as you use it. If you drain the tank, it'll take about 1.5 hours to refill. It does need 2 gallons of unfiltered water to make a clean gallon of drinking water. I've had my unit for about a week and the water is phenomenal. It tastes great and is 10X better than the faucet water. The only slight issue that I had was that they need to drill into the drain pipe to dispose of the excess water from the filtration process. It's a small PVC pipe with a small hole that might need to be replaced when I leave the apt. But apart from that, IWS service, installation, and the unit itself is well worth the price. Highly recommend an RO system with IWS. Oh, and you'll need to replace the filters once a year which IWS will do. read more

Contacted in May, took another call in June to get the estimate. Accepted the quote and given a date for installation. Never showed up or called to say they weren't coming. Called and was told Bryan had a medical emergency and rescheduled. Date came and again no one showed up or called, again was told he had a dental emergency. (I used this company before and that's why I kept giving them more opportunities) We rescheduled again and once more Bryan didn't show up, so I called him and he promised he would be here Friday 8-16 at 9am. Waited until 4 and I called and texted and he never has reached out. I have been calling the office and have left messages and no one has called me back. Save your self the time and stay away, can you imagine using them and then you have an emergency and they don't stand behind their product? Horrible read more

Great company with responsive owners and staff. Jeremy was very knowledgeable and we are extremely happy with our system. Bottle water quality out of every faucet is a dream I never knew could be a reality. read more

Daniel is very responsive and quickly came up with a solution for the sulfur smell in my well water. His son installed the filtration system, hydrogen peroxide system, and water softener system. We can finally feel confident in the water quality. I highly recommend Integrity Water Solutions. read more

Just had a RO system put in plus the water softener. I went with them because of their price and because of all the great reviews on here. I almost felt like I knew Michelle already after reading all these reviews. They were able to come out pretty quickly, within a week. The tech put everything together and my valve behind my fridge broke on the guy which requires a special part since the house was built in 2005. The owner himself came out to my house that night and took care of it. He was very nice and even cleaned the gross dog food we found under the fridge when it got pulled out! I'm now trying to get my friend to get a system. Definitely love it so far and really appreciate the fact that they don't charge a crazy price. read more

After a horrible experience trying to buy a new softener and RO system for my home, I paused on that purchase and reached out to Integrity, and I am so glad that I did. I spoke with Michelle in their office and had a quote in hand within minutes. Not only that, she had me scheduled for installation a few days later. The installation went as smoothly as the sale. Kyle arrived on time and made quick work of getting both systems installed and up and running. He answered all my questions and made sure I was satisfied. Even when I had a question a few days later, he called me back to help, and even provided his direct cell number so that I can get in touch with him quickly. All in all, excellent experience and service before, during, and after the sale. I will be a loyal customer to these folks, and recommend them for any of your household water-related needs! read more

After having the people from Costco over and getting a price that was way above what I had been thinking I started checking around to see if my mental budgeting was way out of line. Turns out the price I was given was about as high as it gets. There were a lot of features and if you want top of the line I'm sure this is fine but this is my first softener so I have no idea what super features I really need and therefor need to pay for. So I checked out the reviews for several more affordable companies and the reviews for Integrity Water Solutions were glowing. I decided to call and Michelle helped me immediately, she was knowledgeable and answered all my questions. Then sent someone out to verify the installation and give me a quote. The person that came out was friendly, professional and also very knowledgeable. I got the quote and decided to go for it. Within a few days I had a new water softener and water filter installed and operational. They did a really nice job with the plumbing and electrical. This was my first softener so they spent as much time as I needed answering questions. About 6 months later, just this week, I had a couple of questions and worries. The biggest was it looked like there was salt all over the outside "decorative" covers. Michelle had someone out within 24 hours to see what was going on. Turns out it is installed next to my AC condenser and when it rains the condensing unit fan blows that up onto the covers for the tanks for the conditioner. It wasn't the conditioner at all. Again they spent as much time as I needed making sure that there was not going to be any damage from this spray, it was just turning the metal cover white. It's not in a place where it has to be decorative so it's not a problem. The main point is that 6 months after getting this thing they came out very happily to make sure I wasn't seeing anything that needed attention. They are a first class company and I highly recommend Integrity Water Systems read more

Super awesome team, product communication. They were honest w me even if it wasn't going to make them the most money! Thank you Integrity!

I am beyond happy with our reverse osmosis system. I had no idea how bad the drinking water tasted even with a brita type filter. I decided the filters were a waste of money and went for the RO system. The tech arrived on time and had our system set up quickly even with drilling thru the granite counter top. We also added the line to our refrigerator to allow for cleaner ice. We all have been drinking so much more water, even the kids! Wish I did this sooner. read more

My 81 year old widow mother had a softener installed several years ago ago from another retailer. Getting service was a constant nightmare. Called Integrity, after using them for a number of years for our own system. They replaced her RO portion of the system to make it easier and it was smooth, very professional, and she is SO grateful to have a system for easier forward maintenance read more

These guys are Rockstars! Water softener was leaking yesterday. Contacted them in a group search. Rapid response back with an hour or two. They could be out next day. Good thing as leak went from bad to worse. AM call to Michelle - very nice and efficient - said they should be out by noon. Phone call let me know when they were on the way. Kyle arrived and went right to work. In no time at all he had the leaks (plural) fixed. Showed my the old parts and explained how the failed. (I was thrilled he had the parts to my 20 year old fixture on his truck!). Here is the thing. I was charged the minimum I was quoted AND the mark up on the parts felt like no mark up at all!!! Having worked in the customer service world for over 40 years I appreciate great customer service. So many potential greats fail the last 10% of the effort. IWS shone the entire time! Kudos! read more

Owner "Bryan" doesn't take responsibility of their workers who comes to our house for yearly serivce. Backgroud : I am owner of 2019 built house. I have RO water filter from integrity water solutions. These guys came for yearly serive to change water filters under my sink and hours later water leak started from my kitchen faucet which is very next to RO system under my sink. Obviously i don't expect my things to work forever in my house but i am not a fool to connect the dots here that it's not coincidence but their broke my faucet connector under the sink. When i called them owner gave a weird example "if i get oil change in car and if flat tire happens then i can not blame the oil change company" obviously he is not doing the right comparison and also his way of talking to a customer is really rude. There are lot of water solutions companies in valley. Please refrain from using integrity because once things are installed they are not giving quality service which matters a lot. read more

We just had our second unit installed at our new home and it's perfect. We love the soft water systems that integrity installs. The are professional, punctual, and provide a great product. Looking forward to my next shower! read more

Contacted Integrity on a holiday (Father's Day Sunday) after our 12 year old GE softener sprang a leak. Received a quick reply from Bryan, who was very helpful in educating me on the issue and potential options for service. Scheduled a replacement in less than 36 hours from initial contact. Our serviceman Cody was prompt, courteous, and professional. His work was top notch. He even had to reroute the pipes leading to the system. It looks fantasic and works like a charm. Will definitely be using Integrity's services for all future relevant needs. read more

I can believe the way this company operates. (Can you?) I've been using Integrity for occasional service on my water softener and regular service of our high pressure misting system since 2016. On 10/22/19 another company told us our water softener was not working and they could rebuild for $700 or replace for $1700 with a 24,000 grain unit (this is a company that services our R/O system annually). As soon as they left I called Michelle at Integrity for her input. She said her top of the line unit (32,000 grain) would be $1,050 installed including disposal of our old unit. I made an appointment for today, 10/23/19 for installation and had asked Michelle that when the tech, Kyle, arrived could he verify the diagnosis on the old unit. She said, of course! Here's the part you may question, at least compared to some of the possible experiences you may have had. Kyle arrived with the new unit but first inspected the current one. He said it wasn't working, but believed that $125 worth of gaskets and a piston would get it going again. Here's the bottom line; He left to get the parts and returned in about an hour, fixed the old water softener for $275 including labor and left with the new $1000 unit in his truck. I hope I don't need that new unit too soon, but whether my 16 year old unit needs a repair or a replacement in the future, Integrity is my company for life. You should get with Integrity, a diamond in the rough! read more

Had a great experience with David. He was incredibly professional and polite, energetic , and overall great to work with. Everything was explained in great detail. The demonstrations were incredibly engaging and he answered every question that we had. My husband and I definitely felt fully informed in making the decision to purchase this water system. So far it has been amazing. The water is incredibly clear and tastes sweet! My husband and I have both noticed softer skin on the first shower with this water. Our daughter, who is a newborn had acne on her face and neck, and it cleared up within the first two baths with this water!! VERY happy read more

Thank you so much for getting us in and being so communicative of what would be placed into the home. We appreciated the quote and run down of items to be put in. read more

Amazing people! They are truly working with Integrity. Plumber sent by home warranty company said we needed a new water softener. Asked Integrity for a second opinion and they sent out Jeremy. Not only did he perform a simple fix on my water softener, he identified an issue that had been puzzling us. Plumber prepared to charge us $1300, Jeremy fixed all for less than $100! Go no further for water needs!! read more

We have done business with Integrity for 7 years now. We have always had professional and quality service, from installation( water softener and RO) to include yearly service on the RO system. Brian, Michelle and the service tech ( Jeremy) are the best. I highly recommend Integrity Water Solutions. read more

GREAT business! Spoke with Michelle in the office, who gave me a quote for a new RO system. I called at least seven plumbers, and was quoted anywhere from $525 - $680 for a new installation! Then I called Integrity Water Solutions, and Michelle promised me $407 out the door. They even got me a same-day appointment! The service man came about 40 minutes early, which took us by surprise, but he was swift and efficient in his installation. He moved the RO and tank as far back as he could to give my renters all the room they need under the sink, and even hooked it up to the fridge so the ice would be filtered as well! The whole process took maybe an hour. When my renters tried the new system, we were shocked at the new water pressure!! They're so excited, and I'm relieved they won't have any more leaks while they sleep! THANK YOU to Integrity Water Solutions. Don't waste any time; call Michelle today. :D read more

Fantastic company to deal with. Just had them install a water softener for us. They were able to problem solve an installation challenge for us quickly and efficiently, and everyone was easy and great to deal with. And the water softener itself works great. Highly recommend! read more

Integrity did a great job for us on our softner from Michelle in sales to the service tech showing up on time. The tech was courteous and answered all my questions and to call or email the office with any questions down the road. We are finally looking forward to having soft water. We like the new softener and warranty that comes with it. We will be recommending Integrity to our friends and family. read more

We picked Integrity Water Solutions based on all the positive reviews and we're glad we did. We were having issues with hard water odors in our laundry and shower drains and needed to do something fast. Their installers were clean and courteous. Soft water fixed the issues we were having and we're very happy. read more

I needed a water softener installed. I called Integrity last week. Michelle answered right away and gave me a quote over the phone and via email. She was very knowledgeable and answered all my questions. I decided to go with them, and the unit was installed yesterday by Kyle. He was on time and did a neat, professional installation. After completion, he thoroughly explained the functions of the unit. I have 100% confidence that Integrity will stand behind their work if any problems arise in the future. read more

Bryan and Michelle are fabulous Solved a problem that everyone other professional I talked to either misdiagnosed or couldn't diagnose Showed up at 9 PM after already working a long hard day because he knew I needed immediate help He immediately fixed the problem. He also pointed out my water softener was not working correctly. No hard sell Actually tried to down sell me by discussing repairing rather than buy new he also fixed up a mess caused by my plumber earlier in the day Bryan is probably one of the most knowledgeable water conditioning professionals in the country. Extremely dedicated and honest read more

I can't believe I forgot to review these guys! I used them for the first time last year. I sent a message through Yelp asking for availability and pricing on a RO filter change and received a response almost immediately. They came out and assessed my old unit and told me that they could change the filters, but that the previous owners had had it fixed so many times with random parts that it would be best to replace it to get the quality, pressure, and volume output that we wanted. We agreed to replace it and a mutually beneficial appointment time was set up immediately. The tech showed up right on time and replaced the unit (along with a new matching ORB faucet) pretty quickly. The RO unit has been functioning flawlessly since then! Recently I received a phone call from Michelle letting us know that it had been a year and that it was now time for a filter change and tune up. I definitely appreciated the reminder, because I suck at remembering that sort of thing. All in all, every single interaction I've had with these guys has been top notch. I've been really impressed with them and would recommend them without hesitation. read more

Integrity water installed an under sink RO system today. The tech was extremely knowledgeable and was able to navigate our less than opportune piping job. We highly recommend using Integrity water solutions for your water system. read more

Great company to work with. Emailed for an estimate, went back and forth clarifying options and they answered every question. Install was a breeze, they arrived on schedule, the installer was professional and quick. Couldn't ask for more. Price was great too, had several quotes and they were among the most competitive. Their high yelp ratings are well deserved! read more

Originally contacted Integrity Water Solutions because I was wanting to bypass an old water softener that was with the house when I bought it but no longer worked. I wanted to bypass because after getting a quote from Lowes for a new one, I decided that it was out of my price range as the quote was over 5K. When Israel came out to bypass the old softener I explained this to him and he told me it would be a lot less through them and got me a quote in minutes. I decided to go ahead with getting a new one as their quote was a few thousand less then Lowes!! Israel came back 3 days later and removed the old, installed the new and configured it in about 2 hours. Super friendly and knowledgeable, explained how the new unit worked and what I needed to do and even passed on some useful info on my hose hookups by my main water line that would have resulted in me killing the plants in my front yard haha. Great company, Israel is awesome at his job and I'm already lining up getting a reverse osmosis system through them. Highly recommend! read more

As I am new to Arizona and it's hard water, this was my first time dealing with a water softening system for our recently acquired townhouse. After contacting a handful of vendors, Integrity Water Solutions stood out above the others by their responsiveness, professionalism, and patience in answering all my "dumb" questions. Their proposal was prepared and forwarded quickly, included many details of the system and reflected very competitive pricing. Michelle made the process simple and pleasant, and the project was executed exactly as she said. I would highly recommend choosing this company for your water treatment needs. read more

Cannot recommend these guys enough! They are so responsive and explain everything that's going on. They've come in to fix what multiple other companies quoted me and arm and a leg for for a very reasonable cost and they are super honest about everything. These guys are not only the best plumbers we've had but the more trustworthy as well. the owner gave me his number and was helping me try to solve the issue with no charge before ever even scheduling an appointment with them. They care about their work and their customers. Don't even think about another company! read more

Amazing Service! I called because I purchased a new home with an RO system. I have never owned one before. There is a screen that shows how many gallons you have left, and it was getting quite low. I have been reading info online and in owners manual, but a lot of it was over my head. There was an invoice from Integrity from the former owner, so I decided I needed to have someone come out and explain it to me QUICKLY. I spoke to Michelle on the phone and she walked me through what I needed to do, is sending me tips and instructions all without a service call! I am so impressed, they will be my RO company from now on. Thank you Michelle! You are a great representative for your company! read more
