RCC7AK, NSF Certified, 75 GPD, Alkaline 6-Stage Reverse Osmosis System, pH+ Remineralization RO Water Filter System Under Sink, Patented Top-Mounted Faucet Design for Easy Installation

Flow was poor from day one . No UV also

Very happy with my purchase, system works well and haven't any issues with leaking, water pressure etc. Love the "taste" of water, so pure compared to my regular kitchen tap. Hopefully it will help me to get rid of my skin issues that I have been experiencing due to poor quality in Perth, Australia. Edit: THIS Filter has saved my skin!!! I have managed to get rid of my extremely bad eczema which no cream / ointment could heal. 3 year update - still love the filters, I don’t drink any other water than my filtered water. It tastes great and has healed my skin! My filter housing broke before Christmas and I freaked out as I can’t be without it! i reached out to iSpring and they were fantastic to deal with! Shoutout to Francis, your help is much appreciated! Best system out there if you have digestion or skin issues! Thank you

We’ve been using the iSpring RCC7AK system for a few weeks now, and we are genuinely impressed! The installation went smoothly, and the components feel high quality. Big thanks to Nick from the customer service team — he was extremely helpful and responsive throughout the registration process. One of the most impressive things: we’ve been using filtered water from the system in our glass electric kettle every day for two weeks — and there is absolutely no limescale at all. Not a trace. This alone is a sign of how well the system works. The faucet looks great and works perfectly, and the tank provides more than enough water for our daily use. Highly recommended! Thank you again, Nick — you’re doing a great job!

REF; RCC7AK 6 STAGE RO SYSTEM: Firstly, I would like to say that the customer service at iSpring is exceptional - Francis to be specific. I had a very minor issue that did not scare me away from this product nor create any annoyance re. installation. Francis quickly contacted and helped rectify a very minor issue I had, following up with me to try and rectify the issue asap - thank you Francis! Packaging & instructions/fitting: The box arrived well packed and packed so well that I would not expect damage during transit. Each item was in its own box and had very little movement. The items came out of the box easily and had no damage. Well packed. The instructions for the assembly and fitment were very detailed. If self-fitting this unit, you probably have some kind of idea about what you are doing so you may not need to use the instructions as gospel, but they do provide a very well detailed and easy to follow assembly instruction. The flow diagram was welcomed too. A nice quick reference guide to hosing. This helped me more than the instructions - I find visual instruction easier than detailed description instruction. Whether you work in fluid engineering or fancy the DIY challenge, the instructions supplied will certainly allow you to install with ease. It took me about an hour to install and commission/leak check. The unit (although it looks rather large) fits very easily inside of my 900mm wide cupboard. It even allows for space around the filtration unit and the reservoir for placing filter spares etc. It certainly surprised me with how well the unit fits inside of my cupboard. I expected to assemble it, offer it up to the cupboard only to find it was too large to fit and then need to send it back… but I could fit two RCC7AK 6 Stage systems inside of my cupboard. Perhaps it opens scope to add further filters elements onto this system in the future… Filters are easy to change. This unit comes with a filter housing removal tool to provide leverage on the housing. Install the filtration system above the base of your unit to allow ease of filter change. There is a detailed commissioning instruction near the end of the instruction so please do follow this for the correct initial start-up procedure to purge the pre-osmosis filters (ensuring you do not put carbon deposits into the RO (reverse osmosis) membrane. Supplied parts: During assembly, I happened to think to myself 'a 90 elbow fitting would be perfect here'... they had thought of that and supplied multiple fittings! More than I needed. The length of piping was perfect. I used about half of what was provided - even with a drain line that extended far down the waste pipe into the next cupboard (install horizontal and away from the u-bend trap to eliminate a dripping noise and potential backing up of sink waste into the drain-line in the event of blockage). All parts supplied fitted my standard UK kitchen (15mm comp / 1/2" BSPP) but I did use some PTFE between the threads just to seal them as the thread form is NPT and my kitchen is BSP (thread angles are slightly different and therefore do not mate perfectly). I have had no leaks in the week I have had fitted. Taste/Testing: The taste is incredible. It tastes pure and clean. No tang or bitterness. It tastes purer than the purest bottled water I have tasted. I will now avoid drinking water that has not been through my RO system. Bottled water at a push! I have (glass) bottles stored in the fridge filled with my RO water. Bottled water is nice... but iSpring RO water is second to none. I agree with another review here that I fill my bottle with this water and take it everywhere I go. See the images for the testing. I believe that these images speak for themselves. Obviously, the RO water cannot be TDS free due to the remineralisation process but down to 47PPM from 435PPM is an incredible job and there is a clear difference in the ‘clean’ taste even between RO water and bottled water. This is evidence enough that the water is truly forced through the osmosis filter. Alkalinity of this water is slightly higher (TAP is 7.66pH, BOTTLED is 8.70pH *Sometimes artificially raised using Bicarbonate of soda, RCC7AK RO is 9.72pH). Yes, I did calibrate my pH meter prior to use! I am yet to perform some detailed research into the difference a higher pH water provides but brief research suggests that it is easier for the body to consume. I will take higher pH being better for the body at face value at this point for this review. Overview: I would suggest that this unit is installed in every home for the sake of reducing the number of chemicals that are consumed through water. At the very least, bottled water should be consumed. Avoid tap water! For the small cost (yes, the cost of this unit is relatively low) this unit is 100% worth purchasing. Fitting is easy, it comes with a nice outlet for the water, water tastes incredible, and the customer service is outstanding. Every home should be fitting one of these units. And whilst you are at it... consider stopping using fluoride containing products such as toothpaste and mouthwash. Use fluoride-free alternatives. I have personally noticed positive differences with regard to dental/mental health. BUY the iSpring RCC7AK! – I was not provided any incentive to leave this review. All opinions are from my experience of using this product!

Ich habe lange nach einer zuverlässigen Umkehrosmoseanlage gesucht, da unser Leitungswasser hier sehr kalkhaltig und „hart“ ist. Gerade wenn man sich intensiver mit dem Thema Wasserqualität und Nährstoffaufnahme beschäftigt, merkt man schnell, wie sinnvoll ein solches System ist – und dieses hier erfüllt genau das, was ich mir erhofft habe. Die Installation war mit etwas handwerklichem Geschick gut machbar, alle Teile waren dabei und verständlich beschrieben. Besonders gefällt mir der zusätzliche Alkaline-Filter, der dem Wasser einen angenehm frischen Geschmack verleiht. Seit der Inbetriebnahme trinke ich deutlich mehr Wasser – einfach, weil es so gut schmeckt und man ein gutes Gefühl dabei hat. Für diesen Preis bekommt man wirklich ein hochwertiges System, das hält, was es verspricht. Absolute Empfehlung für alle, die Wert auf sauberes und gesundes Trinkwasser legen!

We recently installed the iSpring RCC7AK reverse osmosis water filtration system, and we've been very happy with it. The installation was straightforward, but it's worth taking your time and carefully following each step. We did run into one issue because we went back and forth between the YouTube installation video and the manual and overlooked the step of flushing the three pre-filters until the water ran clear before connecting the RO membrane. As a result, the RO membrane became clogged, and the system wasn't functioning properly. I reached out to customer support, and Laurence provided outstanding service. He was responsive, knowledgeable, and guided me through the troubleshooting process via email. He even sent detailed video instructions on how to check the tank pressure. Once we determined that the RO membrane had become clogged during installation, Laurence promptly express-shipped a replacement. After installing the new membrane, the system has been performing exactly as expected. With our water pressure at 65 psi, we're seeing a wastewater ratio of approximately 2.5–3:1, the flow rate is excellent for filling bottles, and the water tastes noticeably cleaner and fresher. It's reassuring knowing we're drinking high-quality filtered water every day. One modification I made was adding a tee fitting and shutoff valve to the 1/4-inch drain line. This allows me to divert the wastewater into a bucket for watering plants or simply close the valve and have it drain into the kitchen plumbing as originally designed. It's a simple addition that gives us the flexibility to reuse the water instead of letting it go down the drain. If you're looking for a reliable reverse osmosis system backed by exceptional customer support, I would definitely recommend the iSpring RCC7AK. Thanks again to Laurence for going above and beyond to make sure everything was resolved.
