May 20 2021 - Another great experience using Water Group 7! Jeremiah has been a superstar and lifesaver! I bought my reverse osmosis water cooler with hot and cold taps almost 7years ago when we were living in Hawaii. We moved to Las Vegas in 2016 and Jeremiah has still been able to offer great customer service! My son recently broke the hot water handle (don't ask me how) but he did. I had been okay with it so far but the other day was just fed up. So I reached out to Jeremiah, told him what had happened and he was like sure I can replace that! Wow! He took a picture of the replacement part and I was over the moon it was an easy process and something I could do. He sent it from Hawaii and a few days later it came in the mail, I called him and he gave me step by step instructions - insisting to be very careful and not to get burnt. Well I replaced it - easy peasy! For $40 - what can I say, I love it! Thank you for always giving me great speedy service. read more

The area that I live is on the older side and the water quality isn't what you would call ideal. It had a funny smell and I want very fond of using it for drinking or cooking. I finally got so frustrated I went searching on yelp and found Water Group 7. Jeremiah scheduled a consultation to address my concerns. He listened to all my issues and was very honest about what he would suggest and what he wouldn't based on percentage rate of effectiveness for the area and also the esthetics. So I decided to go with a reverse osmosis system to at least help with the water quality that I used for drinking and cooking with. The system unfortunately wasn't working properly due to no fault of theirs. But they addressed the issue until the problem was solved. Jeremiah and his brother are so great to work with! I highly recommend Water Group 7 for your water issues. read more

Professional family run business with excellent customer service. Being highly dissatisfied with the service provided by the other company, I contacted Water Group 7. Jeremiah, our sales representative was professional, knowledgeable and very responsive. He was able to answer all of my questions and even provided additional information I was not aware of. Water Group 7 will do everything in their power to accommodate your schedule when service is needed. I highly recommend Water Group 7. read more

I'd give WG7 10 stars if it was possible, 5 for the customer service and 5 for the actual product. This company provides the best of both worlds. We've been customers of theirs for 3 years but familiar with their products from work prior to that. Products - Their reverse osmosis water filter provides a much more enjoyable drinking water than any bottled water you could buy. It's very easy to use and maintenance is an annual cost which comes out to about $20 a month. It taps straight into your water line so there will be no need to make those Costco/Wal-Mart runs to buy cases of bottled water. They also were able to link it to our refrigerator which now has filtered water and filtered ice from the RO water filter system. We also recently purchased a Water Softener and although we are a few days in we really can feel the difference in the the water, the texture, and the feel. They have a bunch of new products for residential and business needs. One of them being a tankless water cooler where filtered water would tap into the cooler and you would no longer have to change a 20lb water jug. Really looking forward to checking out their new showcase room once that is ready. Customer Service - Jeremiah who is the point of contact/manager/owner is superb in his communication and delivery of excellence in customer service. He never was pushy into forcing us to purchase any of his products, took the time to explain and answer each and everyone of our questions, and really helped work with us to find a solution that best fits our situation. They offer free site inspections where he will come and see what type of water solutions you are looking for. He offers his thoughts, tests the water, and gives his honest and helpful feedback. He was very thorough and helpful when he came over to our house to go over a site inspection on how we would do the install and placement of their products. He really took the time to explain what would work and be most beneficial. We really appreciated him going the extra for us. Whenever we had questions via email or on the phone Jeremiah would answer in quick and prompt manner. Another cool thing about this company is that it's family owned, local, and all their products are made in the USA. You really can tell that he cares about the customers satisfaction with his products and service. We plan on being customers for along time and advocates of the company due to Jeremiah and his team. We highly recommend this company for anyone looking for a water filter, water softener, or any type of water issues. Their products and service are second to none. read more

I really appreciate the team at Water Group 7. They have been great about contacting me and following up, answering all of my questions with patience and honesty. They came for a free consultation, were upfront with everything, and I have never felt pushed to purchase any of their products. I have only had this filter for 1 day, but it seems to be working well. There are no signs of cloudiness in the water after the initial flushing. I have no doubt that should a problem ever occur, I could depend on them to fix it. read more

I just signed up with Water Group 7 in Oahu and this has been my experience.. positive simply positive.. They were prompt, courteous, responsive to questions and provided excellent service from the beginning until installation! Very organized and thorough.. The costs involved were also reasonable.. I love the water.. it's an excellent choice.. Thank you..Happy Customer read more

My family absolutely loves the new soft water system and also our bottle-less water dispenser. No more mineral deposits on dishes, in the shower or in the pipes. If you've never experienced soft water you really should. It's quite amazing. WG7 also installed a bottle-less water dispenser that dispenses ice cold and piping hot water on demand. The water is filtered and tastes so good. Can't describe it in words but the water tastes clean lol. This is a must have because the system taps into your existing water supply so you don't need to store huge 5gal bottles of water, which takes up space in your home, not to mention makes you look like a hoarder. This system actually makes your home look better and literally pays for itself. WG7 is highly recommended. They do an outstanding job on installation and they work around your schedule. Very professional at a reasonable price. Check them out! read more

Believe the hype! Jeremiah and Water Group 7 are so professional and educational. I recently moved back to Honolulu and when I lived on the mainland I purchased a reverse osmosis system through Amazon and had a plumber install it. Boy it was such a pain! I could never keep up with changing the filter, keeping the water pressure up and testing the bladder of the system. So this time I called a water professional. Every encounter with these guys was effortless from the initial phone call to making the first appointment to installation. Jeremiah answered every question I had and worked super hard to squeeze my installation in as soon as possible, even as he was leaving on a business trip! He even called me while on his trip to make sure the filter was working properly. I'll be using them again to install a water softener for the whole house soon. read more

Just got my water system in. These guys do such clean work. Amazing service and very professional! My family and I feel and taste the difference in the water. One thing that really bothered me before I got the system was the water spots. Now no water spots on my dishes and shower doors! Love it so much. So happy with my water system! read more

Super honest family business. We ordered the fancy filtered/scented showerhead to get at some of the high levels of chlorine in our area. It's been working great. Jeremiah is a super hard working honest guy who will offer his advice whether or not you purchase his products/services. Totally recommend this business! read more

I highly recommend Water Group 7 as a company that is providing high caliber services and products that ensure your families water needs are completely addressed. From the onset of our relationship they demonstrated a very professional and personal service. They LISTEN to your stated needs and help you chose an appropriate water system. Their installation process is well thought out and designed to provide great accessibility with a minimal impact on space. If you are looking for a company to provide cost effective, quality products and services in a professional manner, Water Group 7 should be your choice. Jeremiah, our representative, did a great job of helping me and my wife make a decision we are very comfortable with. Kudos! read more

I'd definitely recommend this company, Jeremiah was very helpful, pulled a lot of strings and did a small residential RO system installation for us. He fit us into his busy schedule, and got our system put in without having to wait two weeks for a scheduled appointment. He also set up automatic bill pay, there was no hassle and everything went smoothly. read more

We are a dental practice in the Kahala area that made the switch from a large jug deliver system to Water Group 7's solution. So happy we did. No more storing huge ugly jugs in the office, where we have little precious space to begin with!! Water taste great, and the unit is so much nicer looking. Also love Water Group 7's UV system for filling the water bottles on our A-Dec chairs - Lab verified basement level CFU. If you are using a water jug system to fill your chairs, have u verified it's CFUs level? read more

Water Group 7 has the worst customer service. They refuse to send billing to our corporate office, which creates billing delay, which incur late fees. We decided to move on from this company, and they want to continue billing us. They claim we have a long term contract with us, but will not produce the contract for proof. They want us to pay for the entire year of 2016 before they will even talk about the contract they claim they possess. On top of that, the woman in the office will not even give us her name. Just a really sketchy company. We may have to resort to legal means to extricate our company from this unscrupulous company. I would advise businesses to use other water purification services. read more

If you have hard water (or suspect that your water may be hard), call Water Group 7! They are knowledgeable, professional, and courteous. Family owned and ran - you get the expected customer service everyone deserves! Jeremiah, our water consultant, was awesome. He took the time to go over our water quality in our home using industry standard tests (I know this because I use similar tests for my line of work). The consultation service includes educating you about what to look for in drinking water, testing for hardness, testing for particulate count in the water, and what systems they offer. The testing is free even if you do not purchase a system from them which is a plus. If you're in Ewa or Kapolei, you got some pretty hard water and I recommend getting this system. They offer multiple different systems to meet anyone's needs. We also had a reverse osmosis (R.O.) system installed at the kitchen sink for the cleanest drinking water you can get. Overall, the pricing was very fair and reasonable for these systems. It took them a day to install both systems. Overall, my wife gives her stamp of approval and we can really feel the difference! Our water is soft on the skin and we don't worry about residue from washing dishes or sediment in the pipes and toilet anymore! We cannot say enough how much we enjoy our new system! read more

Very satisfied with the service from Water Group 7. I had a water softener and purifier installed in my home. My water tastes so much better now and my skin feels softer because of the water softener. Water spotting has been minimized so cleaning is a breeze. I highly recommend Water Group 7 for your water purification needs. read more

As a longtime owner of a reverse osmosis system, we've grown accustomed to drinking pure and refreshing water. What started out as an absolute requirement for owning such a system, due to the "hard water" on the west side of Oahu, turned into a normal appliance throughout the years. Since purchasing my original unit over 25 years ago from a local bottle water company, it has followed me as I moved many times over. However, when we moved into the "Urban Core" of Honolulu, I decided it was time to consider newer technology for our water needs. Since Watergroup 7 had serviced my original unit and am very pleased with their customer service, I contacted Jeremiah to learn about the new products. He paid a visit to discuss details and features of the new unit such as a leak detector and a water regulator. I did have concerns about spacing for the water spigot, but Jeremiah assured me there would be no issue. In the end, I opted for a 3-stage reverse osmosis system with an upgraded spigot. All in all, I am very satisfied with the unit. The customer service was second to none, with Jeremiah responding to my phone calls as well as answering my emails. The installation team of JC and Jerry did an outstanding job and the upgraded spigot looks great! I've been happy with my experience working with Watergroup 7 throughout the years. And can highly recommend them to family and friends. Another quality system made in the USA! read more

Had Jeremiah consult with us our options on the filters, was very knowledgeable about water filtration and water in general. We are very happy with the water system they installed on our granite counter top. We will definitely use them again. Leo read more

Water group 7 has installed their filter station with our company for a few years now. I'm especially appreciative of it right now since it's summer time. Even though we have air conditioning in my workplace, the humidity and warmth of outside comes through the cracks of the doors. The water filter provides really cold water, I mean really cold and crisp! My hydroflask keeps it really cold and I love it. No need ice, when we have watergroup 7 filter! Also there is an option for hot water too, it's super awesome. They always do maintenance checkups as well, love the staff! read more

I had the filtration system installed one year ago, and today I had the filters replaced. If you're tired of purchasing bottled water, carrying it into your home then tossing all of that wasted plastic out...look no further! Water Group 7, thanks to Jeremiah and his team provide nothing but friendly professional service & fabulous tasting filtered water read more

After moving here over a year ago, we decided that we couldn't live with the hard water and the effects on our new home anymore. Plus we wanted RO water to drink and to use to fill our fish tanks. We shopped around and even though Water Group 7 was a little more expensive, we went with them instead of another company because of reviews. And also, when Jeremiah came to our home for a consultation, he was extremely knowledgeable and had everything in a quote so there was no guesswork or surprises. That was over a year ago. Since then we have had a perfectly running system, excellent drinking water, great water for our hair and skin and the damage from hard water is gone from our home. They just called recently and came over to test and do the one year change BEFORE the alert for one year maintenance even went off in the garage! It is a family owned business...very ohana, very professional and they stand behind their work. I called (probably bugged) Jeremiah with some questions and he always called me back promptly and was happy to come over and check or explain something. These guys are the BEST (and I'm not an easy customer!) and isn't it nice to be worry free when you are taking care of your home? You get what you pay for and they are top notch! read more
