RCC1UP-AK

I couldn’t be happier with my iSpring RCC1UP-AK Reverse Osmosis Water Filtration System! As someone who’s been concerned about the quality of tap water, especially the fluoride content, this system has completely changed my peace of mind. I’ve always been cautious about the water we drink and cook with, and now I feel so much safer. Setting it up was pretty straightforward. The instructions were clear, and the system fit under my sink without any issues. After installation, I tested the water with a TDS (Total Dissolved Solids) tester, and I was amazed to see that the water was at a perfect 43 ppm – that’s incredibly low and means the filtration is working exactly as promised. For reference, my tap water had a TDS reading 155, so this system really makes a huge difference. The taste of the water is noticeably better. It's crisp, clean, and refreshing – perfect for drinking, cooking, and making coffee or tea. I feel so much more confident using it in all aspects of my daily routine. Overall, I highly recommend the iSpring RCC1UP-AK system to anyone who’s looking for a reliable, high-quality reverse osmosis filtration system. It’s a fantastic investment in both health and convenience. If you’re serious about water quality, this system will not disappoint!

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 think When 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.

Did a lot of research and reading and ended up going with the iSpring RCC1UP-AK. I like that it is a true 7 stage (meaning 7 actual vessels the water passes through). And that it has a large UV vessel (powered) along with a powered pump (very quiet) for added pressure when filling. The instruction video was good and straight forward. I didn't have any questions during the install that weren't covered in the video. For the drain line I ended up using a garbage disposal adapter (https://www.amazon.com/dp/B08YP9VKHZ?ref=ppx_yo2ov_dt_b_fed_asin_title) to avoid drilling into the waste piping. I'm also impressed that iSpring provides a leak/flood shut off valve. Even though it is mechanical with a disc that needs to be replaced once it gets wet - it's a great adder. I've only had it installed for about a week and so far, it is operating fine - no problems. I will eventually do a full water test report to verify clean water. I did, per another reviewer's suggestion, go ahead and add a 3 way valve to the last pre filter output. That way when I need to replace the prefilters and do the initial flush I can just flip the 3-way valve (https://www.amazon.com/dp/B0F7HQMH7L?ref=ppx_yo2ov_dt_b_fed_asin_title) to the hose that I can run to the drain. This avoids having to disconnect the red tubing and connect to the drain as described in the install video each time I replace the prefilters. Also, I have considered adding an additional faucet for pure RO water before the Alkaline adder. That way I'd have a choice between pure RO water and clean RO water with minerals added back in. I did put an electronic water leak alarm (https://www.amazon.com/dp/B0CKYTP2DM?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) and a rubber water catch mat (https://www.amazon.com/dp/B0D6YWKXVC?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) in with the RO system as a just in case. And thanks to Julius for securing my 3-year extended warranty.

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.

This review is for the following: iSpring RCC1UP-AK 100 GPD 7-Stage Reverse Osmosis Under Sink Water Filtration System with Boost Pump, Alkaline Remineralization, UV Filter, and Top-Mounted Faucet; purchased 8 Jul 25, installed 17 Jul 25. iSpring WGB32B-KDS 3-Stage Whole House Water Filter with a 1st Stage Anti-Scale Water Filter, 2nd Stage GAC+KDF Heavy Metal Reducing Filter, and a 3rd stage Carbon Block Filter; purchased 20 Jul 25, installed 27 Jul 25. iSpring WSPSL-ARJ-BP Spin Down Sediment Water Filter with Siliphos and Touch-Screen Auto Flushing; purchased 20 Jul 25, installed 27 Jul 25. I wanted to install a drinking water filtration system for several years but never had the time to do it. Now that I’m retired, I decided it was time to finally get it done. Our city water source in Alaska meets “approved” levels for water quality, but always has a sulfur smell, and scaling is also a problem. To add to our concerns, we often get sediment when we have earthquakes near our area. I spent a great deal of time reviewing various filtration systems on the internet and Amazon to find the best fit for my needs. Though there are many good systems out there, I chose iSpring because they offered the best options and had the best reviews for filtration systems and customer support. I first purchased and installed the RCC1UP-AK 7-Stage RO/UV drinking water filtration system thinking that was all I wanted. I mounted it in my basement crawl space underneath the refrigerator because of the ease of running wiring for an electrical GFCI receptacle from my garage circuit breaker panel to power the booster pump and UV filter, and because of the way my PEX piping is routed. I’m very qualified to perform this type of work but wouldn’t recommend someone doing the same if not knowledgeable and qualified, that includes splicing in valves and connectors for PEX tubing and installing the filtration system, not to mention any electrical work. It took me two days to get everything installed from running a feed line for the drinking water sink faucet, creating a filter bypass line, splicing into the refrigerator ice maker/drinking water line, running an electrical circuit, and mounting and activating the new RO/UV filtration system. To say my wife and I are pleased with the quality of the drinking water we are getting from our new filtration system would be an understatement. Whether we get the drinking water chilled from the refrigerator faucet or from the new sink faucet, the RO/UV filtered water tastes outstandingly fresh and pure. And the bonus of having the sink drinking faucet is we can now wash our fruits and vegetables in purified water! Should anyone want to know, the TDS readings for our unfiltered water supply runs around 250ppm, but coming from the RO/UV filter, it drops to 12ppm. Because of how well the RO/UV filtration system works, and because we still have the problem of the sulfur smell, scaling, and earthquake caused sediment coming out of the rest of the house faucets, I decided to purchase and install a Whole House Filtration System. Again, I went with iSpring for the same reasons I installed the RO/UV Filtration System. However, I decided to go with their ultimate filters for the 3 stage Filtration System and the Spin-Down Sediment Filter. Again, I installed the system in the crawl space, but next to the water supply entrance and extended the electrical circuit for a second GFCI receptacle to power the Sediment Filter Auto Flush. This time, it took me 4 days to complete the job because I took advantage of the incoming water shutoff to splice in SharkBite Max cold/hot water valves to every feeder line in the house for individual isolation. What a difference having a Whole House Filtration System has made to the quality of our water. It has been just over a week since it went on-line, and the results have been absolutely incredible. We no longer have the sulfur smell, and scaling is completely gone. We haven’t had any local earthquakes yet, but I’m certain we won’t have a sediment problem either. I can also comment on iSpring’s customer service. I took advantage of their free 3-year warranty extension by registering the products on their website. I’m not going to say it was easy to input the information on their support page because it doesn’t seem to function very well. It took me at least 3 tries for each of the Filtration Systems because the website kept giving errors and locking up, but perseverance prevailed, and I was finally able to register all three systems. It didn’t take but a day to hear back from Sean and Nick respectively to let me know that my 3-year warranties have been activated. Though I didn’t speak to them directly, I’m certain I would be very happy talking with them to help me with any issues I might have. Other reviews mention how helpful customer service personnel are or have been and I can believe it. Bottom line, I highly recommend iSpring Filtration Systems for your drinking and/or whole house filter needs. You won’t be sorry! And check out the attached photos to get an idea of my 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.

PRODUCT: I tried a few other R/O systems and this one is as good as it gets for residential. I'll explain. If you really want high quality , safe and delicious water to consume then you have to have the 7 stage system at a minimum. An R/o system is essential because not only will your water be pure but when combined with the UV light you are now essentially addressing everything that can be wrong with water. Your handling heavy metals, viruses and bacteria. We all can buy a carbon filter and such but they do not protect you against the real issues with "bad" water. You need the whole system to have the highest quality water possible. I will get to one other VERY important feature that this system has over the others but let me make one more point. This system has the common industry filters, then combines the R/O and UV to address the very small micron size particles and of course they have filters that add back essential minerals because pure unmineralized water is actually bad for you. Pure unmineralized water wants to attach to other molecules and it will do that by stripping your body of minerals such as calcium. Pure water is actually a very good solvent. So re-mineralizing water is not just about adding taste. You shouldn't want your water to read 0 on a TDS scale. The important part I wanted to mention was this system comes with it's own built in water pressure booster. This is important because the proper pressure is needed to make an R/O system work properly and to minimize waste water. An R/O system can not do it's job correctly if the water pressure isn't within the range of the specific R/O system you are using. Since this company knows exactly what that pressure should be, because it's their equipment, the booster pump delivers the proper operating pressure at all times. This water is simply a pleasure to drink. SUPPORT: The seller was fantastic to work with. Like I've stated in the past I've tried these systems before from other companies, and my opinion of good water is that it should have 0 after taste and almost feel like air going down. You should taste nothing as hard as you try. Well when I first put in this system and ran through all the startup protocols I found I wasn't getting the taste I expected and the TDS read really high. To put it in perspective the poland spring water bottles I tested in the 16oz plastic size came to about 30-35 TDS very consistently. Almost always 30 on the dot. So remineralized water from an R/O system should not be above that in my opinion because then water starts to have a "taste". Mine was above that and it had a distinct metallic after taste. I contacted the seller, explained how the install went, completed the protocols they asked me too and while still not completely happy they shipped me additional parts to swap out. All this happened within just a few days. So between response time, being empathetic to my problems and providing a tangible fix these guys we're great. The only reason I wrote this long review is because I remember my journey from just learning about these systems and what to expect from them health wise. And if I can compact as much important information as possible maybe your journey into picking the right solution for yourself can go quicker and less expensive then mine. Also any seller, especially on Amazon that makes a customer fell like their issue is super important deserves the accolades that I am happy to give.Between this seller and the product you will not be let down. Good luck everyone and a thank you to other reviewers that helped guide me in my own confusing purchases. If you reach out to the seller or customer service ask for SEAN. He was the best!

iSpring RCC1up-AK After researching the many RO water purification systems now available for under-sink installation, my decision to go with iSpring equipment was made based on these overwhelming factors. The guarantee that the filtered water will be taste-free, have low solids/proper PH/with healthy levels of minerals. Each of these benefits must be independently confirmed with true documented measurable results. The equipment had to be DIY installation, maintenance, and if necessary - repairable (to include all such support documentation to explain the theory of operation, troubleshooting, component level identification, and replacement. There had to be good evidence of absolute company support at every level - from compatibility research and purchase, to integration of plumbing for installation, tips for troubleshooting, scheduled maintenance, repair, and near-instant customer response and support. The final catagory I compared was that of pricing. This included initial purchase, installation, scheduled maintenance, and operational costs. With the ever growing potential for fake or biased customer reviews being planted everywhere online now days, common sense and scrutiny must be applied, but the one common trait that was clearly present in all reviews for iSpring products was the overwhelming personalized customer support. The iSpring support personnel are known and referred to on a first name basis. I found this to be 100% true and accurate, since my specialist (Sean) returned all calls, emails, texts, and requests without hesitation. The system I selected is being used at our house (in south MD) which uses well water. The DIY installation went fairly smooth. I did add a new AC power receptacle under the sink for closer convenience - but other kitchens may already have one nearby that will work just fine. I also put in a “tee” inline to feed the filtered water to our refrigerator/ice maker. These “kits” are VERY well designed by iSpring and carefully considered. They have about every single component needed to integrate the system into your current plumbing and the documentation is thoroughly written - to include color diagrams and tips for those who may be unfamiliar with the methodology employed for push-on connections, tubing, or other basics utilized along the way. The only “real work” item to be carefully planned and implemented upon installation might be the placement and “hanging” of the system on its vertical axis, on either an existing bulkhead or wall (under the sink or where ever you intend to mount it). It is not difficult- but since its filter cartridges must be changed at some point on a schedule, the location and space should be considered to keep things simple. Our sink had one of those worthless soap dispensers in it - so I removed it and relocated the hand sprayer over to mount in its hole. That gave me a nice location on the far right to mount the new filtered water faucet. This looks great - (and I did not have to drill any new holes through our counter top). Our tap water tested 244 TDS (before filtering). After the filtering the test shows that number to now be 44. We have a small (30 yr old) salt-powered water softener downstairs to help with our water. Its not a modern unit but it may help a bit. However, my primary concern and goal was to purify our bad tasting tap water - to the extent that we could enjoy drinking it, finally replacing our dependency on bottled spring water. THAT seemed a TALL ORDER. I am very sensitive (picky) when it comes to detecting even the faintest taste - when drinking water. So how did it turn out? I am relieved to say that for the first time in the 37 years of living in this house, we are finally able to enjoy drinking the water dispensed from our kitchen sink. We use it for everything we drink. We keep 2 pitchers full in our fridge - we use it for coffee, espresso - even our 2 kitties get it in their water fountain. No more buying bottled water or carrying those heavy cases from the grocery store. I only wish I had done this years sooner - but regardless of the past - we enjoy it now. Anyone on the fence concerning the decision to select the best system for the cost and effort can choose iSpring without any hessitation. Their systems, the results, and the support from the company are all unrivaled. I am so glad I chose iSpring.
