iSpring RCC1UP-AK, 100 GPD 7-Stage Reverse Osmosis Under Sink Water Filtration System with Boost Pump, Alkaline Remineralization and UV Filter, Patented Top-Mounted Faucet Design for Easy Installation

I live in Midland, Texas and the water out here is very hard. I bought this system back in November 2024 and finally got it set up 2 weeks ago due to kitchen remodel. It was very easy to set up, and simple step by step instructions. The filters are very easy to place in and easy to connect and disconnect. I had no leaks upon setting up due to the clamp rings that they provided. I did a little extra and spliced the outlet and had it going to my ice maker and to my refrigerator. I will say that there is a drastic improvement with the taste and quality of the water itself. Since this system makes it an alkaline water due to the filter, it is very healthy for the body. This is a very great price since this a 7-stage filter, and they sell the filter kits separately.I would highly recommend this to everyone that is looking to have their own R/O system instead of using other water services like Culligan or Puragain. System is very quiet, and the tank is the perfect size for what I have it hooked up to.

I searched the internet for a complete drinking water filter solution as the utility water where I live is not reliable for drinking. I decided for the iSpring 7-stage one (filters, Reverse Osmosis, booster pump and UV unit) a good combination of functionality in the right price range. Good reviews, and an extensive documentation and support area also helped on my decision.I received the unit complete with manual and spare parts (o-rings, L connectors, lock rings etc) well packed and in perfect condition. The pump, top filters, RO membrane housing, UV units, drivers come pre-assembled in a metal frame and with all the water tubings connected, except those for the tank, supply and dispose water which are dependent on the installation area. I left the unit free just standing on the the 3 bottom filter housings leaning as the space was tight and there was no risk of tipping and tumbling over. Otherwise I would highly recommend to use the supplied screws and secure it fast to one of the cabinet walls.The installation manual/instruction is well illustrated, color coded and thorough. It took me about 2-3 hours to prepare the AC outlets (two needed, one for the pump and the other for the UV lamp), setting up the incoming and the RO dispose water connectors and tubings, plus drilling the hard granite countertop for the supplied water faucet.The support team was quick and professional to reply to a question I had, and provided me with an easy to install solution.Tips from my experience:1) VERY IMPORTANT: DO NOT RUSH tearing the plastic foil wrapping the large three filters before reading the manual. As written there, do NOTE that on some of the labels of these filters there is a flow (an arrow) indicator showing the direction it should be mounted inside the filter housing. I find there could be a more eye-catching sticker on those filter packings, or the mount indication on the filter itself, something like, this side up/top. It took me a while to figure out the top side, the softer washer like side, I thinkWhen rushing to open the RO element which is vacuum packed, I found it quite odd that it was moist and dripping, but that is described on the label I did not read, and on the manual, I read later. It is some kind of protective liquid (do follow the instruction and discard, at least, the first 15 minutes of water before drinking anything— actually HEED all steps of the start-up procedure before opening the supply water valve and having the water flowing through a new filter)2) The start-up part in the manual asks to verify if the UV lamp is working. There is an indicator light on the ballast/driver when it is on, but what about the lamp inside the metal housing? It is not possible to see it during the day. Only when it is DARK. The enclosed picture of my installation was taken in the dark. Note the blueish glow of the UV lamp through the plastic water connectors when it is on.The lamp will only go on when the faucet is open (the flow sensor connects to the ballast, and triggers the UV lamp on) but it will not turn off immediately when the faucet is shut. There is small delay but eventually it will turn off automatically.The ballast/driver was not fixed to the frame. I just set it on top of the pump adapter which was tied to the frame with a screw, arranged the cables neatly around it, and fastened it with two cable ties to the metal frame.3) Although a small leakage alarm is also provided, the whole unit is pretty watertight, specially when considering the number of filters, tubing and connections. I noticed only one small leak at an L/elbow connector attached from the last filter (alkaline/mineral) with a tubing to the flow sensor of the UV unit. None of the other connections had any leaks. Instead of fighting this connector, I figured out a much simpler solution.This connector was an insert type (they call it stem type) as opposed to the other threaded ones. Since this filter had the same quick connect fitting (with a lock ring), I just used a piece of excess tubing (on my picture, the yellow one between the filter and the UV unit) to replace this connector (do follow the manual instructions to re-insert those tubings correctly as it is counterintuitive when removing a tubing from the fitting), and the leak was gone.4) You have to physically shift the RO unit to the side so it protrudes a little bit to fit the opening tool (the black, round one with a smaller diameter, the larger one is for the 3 main filter housings at the bottom of the frame.It has been almost a month, a very positive impression, no problems, no leaks, great water quality, a real improvement when compared to our previous tap water.

Updated Review Below after dealing with customer service to fix the system.Edits: The system has been five stars all along, however, there was a period when I had given it 4 stars due to the difficulty in obtaining replacement filter packs. I was told by customer service this was due to the pandemic and supply shortages for the UV bulbs. In the past 6 to 12 months I have not seen any filter supply outages. I am re-instating five stars.I own a residence in the country and I am on well water. I drink a lot of water. For years I had a water cooler and had 5 gallon bottles of water delivered. So I am very used to the taste of that water. I decided, as a way to save money, I would get a RO water filtration system installed under the sink of my house. After researching for a fair amount of time I ended up purchasing the 7 stage 100 GPD iSpring RO system in late 2019. I watched the installation video and read the directions. It was pretty simple to set up. It does take some time to get it completely installed. I took my time and I am happy with the final installation. I feel that the video and the written instructions are very good to help get the system installed.After the installation the instructions state to fill the tank and then empty it. I followed those directions. At first I wasn't a big fan of the taste differences. I can tell the difference between a lot of the off-the-shelf bottled water, so I figured this would take a bit of time to get accustomed to the taste of the local well-water and the difference in how the final product was filtered. As time went on I started to enjoy the taste of the water.One of the big reasons I got this system was the protection from possible pollutants that could get into the water. I have the well system tested, but that only tells me the water is okay at that point-in-time. I have no idea if it is still good a month later. This system gives me peace in that regard.I am satisfied with the system. I am happy that I got it and I am no longer buying bottles of water.-----UPDATE 012322-----In December 2021 I started to have an issue with one of the lines. I made a short video and E-mailed it to customer support. I worked with one of their customer support agency, Francis. We exchanged E-mailed back and forth.The first diagnosis was a faulty solenoid. Based on where I could visibly see the problem, I felt that he was correct and was excited to receive the replacement part, which was covered under the warranty. But after I replaced it, the problem still was happening. Francis then said he would send out a whole new head unit to ensure the problem was fixed in a timely manner.I had just changed the filters approximately one month prior. The filters are good from anywhere between 6 to 12 months. So I wasn’t too excited about having to put in new filters. Francis also hooked me up with filters so my new ones didn’t go to waste.The new head fixed the problem. It fixed the problem and I am up and running.As far as customer service goes, I am happy. I didn't get a run around. I got replies from Francis within the next 24-hours. He did what was needed to make sure my system works.
