iSpring RCC7AK-UV, NSF Certified, 7-Stage Under Sink Reverse Osmosis Water Filtration System with Alkaline Remineralization and UV Filter, Patented Top-Mounted Faucet Design for Easy Installation

I purchased this 7 stage (iSpring RCC7AK-UV) to help with a well problem on a property we recently purchased in back country of Maine.Water testing on the well revealed dirt bacteria, which wasn't resolved with a proper shock of the well, and the mineral content and other things were not quite right. The result was the water was safe to drink, but cloudy, off tasting and likely to be drank by anyone that saw it. So after researching, talking to experts, and consulting water and well drilling companies, it was decided that likely I have a cracked casing, or a shallow well. Both of which need to be fixed at some point int the future, but were not eminent catastrophic problems, or preventing us from living there.Since it was only drinking of the plain water that was a concern, we decided to focus on a single tap/sink/faucet filtering system. There was no question about which to buy. iSpring has perfected the right unit that has a complete system all in one, that is east to install with great instructions, videos available and even extremely knowledgeable live staff support Monday through Friday. This was essential to the my success with the system.I was told by a local contractor that my pressure was adequate and met the minimum requirements for the ispring system, so I went ahead and ordered the system without the booster pump. I decided to install the system to provide water to the refrigerator ice/cold water dispenser. Perfect for that application since it can handle up to 75 gals per day, which we will never reach as a family of three. My problem turned out to be the fact that the pressure was not adequate, and I was miss-led by a local well company telling me what my head pressure was. I called ispring support in hopes they could advise me on a solution, assuming I would have to go find a booster pump and pressure switches to adapt to the system. To my surprise, they had a much different solution.The reps name was Josh, and if you get a chance to speak with him, you will be taken care of with the best of customer service. He was quick to understand my situation, and rather than focus on my issue of not knowing my system and buying the wrong product, he quickly offered a solution where ispring would ship me a whole new head assembly, including the booster bum and pressure switches already built in to boost our water pressure, and would ship for free second day if I just paid the difference of ($90 in my case) for the upgraded head. I immediately took him up on the offer and sure enough in two days I received the whole new head ready to be installed. I moved overt he filters, and the last two stages (6/7) to make it complete.It was up and running within an hour and after following the proper stat up procedure to clear the lines/filters, the water it produced was crystal clear, no discernible taste and was comparable to a product we always choose if in a bottle, "Poland Springs" out of Maine. I even received follow ups from Josh to make sure that it was working and that I was completely satisfied with the product. Not only 5 stars for the product, but for the customer service. Well done all the way around. I would not hesitate to recommend this to anyone, heck I already recommended it to a friend that has a camp in the mountains.

I’ve been very happy with the iSpring RO system — the product works extremely well and delivers clean, great-tasting water. The installation was straightforward, and the quality of the components feels solid.What really stood out, though, was the support. Nick from the iSpring support team was very, very professional. He explained everything clearly, quickly, and thoroughly, and made the whole process smooth and stress-free. I really appreciated his help.Highly recommend both the product and the customer service!Han (Maryland)

TLDR: Easy color coded installation (even easier with Youtube tutorials), clean water that is better than any bottled water on the market, and a fantastic technical support group that will go above and beyond to help you. Thanks again Sean.I finished the installation of the iSpring RCC7AK-UV about 3 months ago and it is easily one of the best investments I ever made. The water tastes so clean that I would prefer it over any bottled water (which now doesn't taste as "clean" as it used to). As good as the product is, the technical support is even better.After installing the under the sink water filter, it was not able to function properly, since the connection from the check valve and the RO membrane was cracked (most likely from a return of somebody "attempting" to install the water filter). I called technical support regarding the issue was assisted by Sean, who I would highly recommend you ask for if you call for technical support. After diagnosing the issue, he sent me a replacement house for the RO membrane and another check valve.Once I switched out the old parts for the new, all of my problems went away and I was finally able to enjoy the delicious clean water that this under the sink system provides. The water is cleaner than anything I have ever tasted in my life and with the addition of the including alkaline filter, I don't lose any of the minerals associated with the reverse osmosis process. I no longer have to buy bottled water, which saves quite a bit of money. I'm also not using an abundant amount of plastic, which is horrible for the environment.I cannot recommend this product any more than I already have. If you are on the fence about buying a water filter, this is a fantastic option. Also, if your tap water source is treated (like from a city), then do not get this item and instead get iSpring RCC7AK, which is the same thing, but without the UV light. If you have any issues, the iSpring team will go above and beyond to help you. Thank you again Sean! I hope you are able to help more customers like me.
