iSpringRCC7AK-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've had this RO system installed for several years an it has been absolutely solid. Everyone comments on how great the water tastes, even my dog prefers this water! Our refrigerator ice cubes are crystal clear. Installation was straight forward and directions were easy to follow. Replacement cartridges are easy to find on Amazon and reasonably priced. They are simple to install and last longer than the recommended interval. I did have to call for support once and Michele was absolutely stellar. She explained the issue and had parts out to me immediately at no cost. The issue was with my water pressure, and not the unit itself. She very kindly offered to send me a pressure regulator and repair parts and the repair was simple to perform myself. I highly recommend this kit to everyone that asks me and even my Dad and Daughter have installed one after using mine. If you care about clean, great tasting water, just get it. You won't be disappointed.

I’ve had the 7 stage RO system since 2019. It’s the best purchase for my house. I am educated on the importance of drinking water quality, fluoride, and microplastics. I also understand the bottle water we purchase in stores aren’t that filtered and contains traces of micro plastics and potential plastic that clings on to the plastic bottles. Drinking them is not the best choice for health.I appreciate the quality, performance, and efficiency of the system. Now My household enjoys an alkaline great tasting water. From the packaging to the easy to follow instructions, and the quality made me choose this system. Also, parts availability for filters is easy and cost effective. I never have to buy bottle water again. I use a refillable bottle and fill it up using my system and I save and enjoy the health benefits that come with it.Their warranty and support is also top notch. I recently called them up to see about purchasing a metal part that holds the entire system together as mine is rusted. A few emails and a call later they not only shipped me a replacement bulk head piece but for free. And my warranty has been out since 2019. But it’s been running perfect since. That’s how much quality this system is.Outstanding quality, support, and parts availability. I’ve referred many of my relatives and friends to their Amazon links for purchase and installation in their own homes. I even assist on the installation. Because seeing them drink healthy water makes me feel happy as well.

First things first, I have well water and a whole house filter system in place that includes a sediment filter and chlorinator. The system was installed when I bought my home and the water tasted really odd, which I assume is because I had to add bleach to the chlorinator. There are mineral deposits on all of the shower heads and in the metal sink drains from the pre-existing system, which tells me that something isn't working very well to make my water pure.I have been buying Aquafina 24 packs of bottled water @$5 for years going through ~5/week that comes out to ~$25/week (unless the prices vary). I was gettin tired of having to carry the water into the house and having to recycle over a hundred plastic bottles per week. In addition to those bottles I was also buying 3 one gallon packs of distilled water for my coffee machine.I finally had enough and decided to sign up for water service from Crystal Springs, which to put it briefly was a total disaster. Every step of the process with this company was a struggle from the initial sign-up, through deliveries, to cancellation and picking-up equipment. I really don't recommend these DS water service (Crystal Spring) people if you have any alternative. Putting it in perspective, I spent less time setting up my iSpring seven stage filter than I did just on hold waiting to talk to DS customer service.With a little background established, I have to say that I had a fairly easy time setting up the filter system because I didn't have to drill a hole in my counter or sink. Instead, I elected to remove the handheld dish sprayer from the side and utilize the existing hole for the filtered water faucet. This was a bit of a hassle for other reasons than the installation of the filter, particularly that I didn't know how to take the sprayer apart for removal and then I reassembled it incorrectly. I will be replacing my main faucet with a sprayer style built in to resolve the lack of a sprayer for my dishes.The entire installation too me around 2.5 hours with some interruption and sprayer complication. I cycled the system per the instructions to flush out the tank and filters. The water initially was a little cloudy after purging and refilling, so I flushed it again to be safe. The water was a little clearer and tasted pretty good over the pre-filtered state. I left the tank overnight and had a glass of water the next morning and noted a very odd taste and smell to the water. Before purchace, I read several reviews of the system and was concerned that I was getting stage 7 (untraviolet light) contamination as others have indicated they experienced. Per other reviews I tried filling and emptying the tank a few times, but after a few hours it seemed like the water started to taste nasty again. I was about to return the system and chalk it up to another failed venture, but I decided to give iSpring customer service a chance to see if there was another possible culprit. They said that the tank is to blame because of the bladder that it inside of the standard tank. It is some sort of plastic or rubber material that some people are more sensitive to thank others. They suggested that with regular use the taste would even out and become more balanced, but I'd already tried emptying out the tank several times with no improvement in taste after a few hours of sitting. They offered to send me a new "special" tank that is redesigned for people that are sensitive to the other tank. I accepted the replacement tank offer and waited for it to arrive. They said that I could use the system with the tank turned off, but the flow of water was almost nonexistant, so it was pretty unrealistic to use the system without the pressurized tank. It took ~4 days to get the new tank and just a few minutes to install it, but WOW what a difference! The water is no longer cloudy and the smell is gone. This now meets most of my water needs since I can fill drinking glasses and my BPA free water bottles for when I'm in the office or on the go. Thank you for the replacement tank iSpring, please consider including this tank by default on all of your newly purchased kits. I saw that you've taken customer feedback into consideration with the untraviolet light portion by adding the pressure switch to the kit based on customer feedback. I'm certain that all new customers will appreciate the "special" tank as a part of their kit, even if the cost is increased slightly.After everything that I've been through just trying to get clean water, I recommend this system to anyone wanting a better alternative to bottled water or terrible delivery servce.
