iSpring 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

I’ve been very impressed with the iSpring RCC7AK reverse osmosis system. The improvement in water quality was immediate — clean, crisp, and smooth tasting. The alkaline remineralization stage is a big plus and really makes the water taste better than bottled water. Installation was straightforward, and the system has been running flawlessly. Filter replacements are easy and reasonably priced, which makes this a great long-term investment. I also want to highlight iSpring’s customer support, especially Nick, who was incredibly helpful and knowledgeable. He took the time to answer all my questions, addressed my specific needs, and made the whole process stress-free. It’s rare to get that level of support these days. Overall, this is a high-quality system from a company that truly stands behind its product. I would definitely recommend the iSpring RCC7AK to anyone looking for cleaner, better-tasting water.

5/9/2017 - Upgraded to 5 stars. You're supposed to change the filters once every six months. It has been three years since I have installed this system and I have not done a thing to it. I should also note we have HORRIBLE water in my area. Today, I decided to purify it and change the filters. So far, I've only removed the third-fifth stage filters so I can purify it (don't want the natural water through the system, so I left the first and second stage in). For three years of use, I cannot believe how clean the third stage and membrane cylinders were. Moreover, the water still tasted fantastic. Even if the company has not fixed their instructions (see below), the performance of this RO unit is well worth the price. ------------------------ I'm installing this system now. When I opened the different plastic parts, they were all wet! Literally water in every one. So I came on line to find out why/call the company. Turns out, they're open 9-5, EST. Would be nice if they remembered that there was a lot of people on the West Coast as well. Nevertheless, after searching around, I found this line. "Our RO systems are 100% wet tested before shipping " Great! But, what does that say about how they dry/ship the product if they're wet when they're being shipped? Or, for that matter, how do I know mold isn't growing in the lines on the faucet side of the filters? Not impressed so far, but will update again as I finish and see how things go. UPDATE: The RO system is now installed. Problem: There was a few frustrations with the installation, but only one that is the fault of the company: the instructions! They are not complete by any stretch of the imagination. If you're looking for a simple start here and end here with a functional RO system, you won't find it. What you do get, is a set of papers that show you two or three independent how-to's: how to install the water tank shut off valve; how to install a spigot; how to install the filters. There's no steps for putting the individual units together as a single RO system. They do, however have an expanded picture on the front, so if you're a visual learner, you can put it together (and really, it's not *that* difficult). Yes, there are videos on the website/youtube, but I expected at least a decent set of written instructions. More Positive note: After everything is installed and I tasted the water, it was exactly what I was hoping for. I was replacing another RO system (five stage) and had bought the six stage with the hope of reintroducing a little more taste to the water. It did that, and did it well. By that, I mean, it's almost unnoticable, and that's a good thing. There's just the hint of taste as you would expect in good water. It's not a taste that will overpower anything you use it to cook in, or anything you mix it with. We filled and emptied the tank twice before keeping the water (I tasted it on the second empty, and it was already good, but we went ahead and emptied it again just to be sure). So, thumbs up for that. ---------------- Installation tip: if you're replacing another RO system, make sure the hose sizes are the same. I didn't, and I am frustrated because I had to tear out all the connections (or by reducers). This issue has nothing to do with iSpring, it's just my own lack of checking. So, make sure you check the size of hoses you're replacing. The hoses in this system are ALL 1/4 inch. And now, I have to go replace a leaky shutoff valve . . . but that isn't iSpring's fault either since I bought it at Lowes for this project. Oh, and one last thing. Note how quickly my review was responded too by the company, and how they were NOT defensive. They explained what they did, and offered help. That alone is worth the headaches mentioned above. Updated from 3 stars to 4 stars. Bad paperwork and shipping wet plastic parts kept me from the fifth star, but don't let that influence you not to buy this RO system. It looks as though, in hindsight, it's going to be worth the money. Update #2: Great tasting water, and worth the hassle/headache. I'm still deducting a star for the bad set of written instructions, because they really are that bad, but pairing it with the pictures and the video, anyone should be able to put it together. It is definitely worth it. Update #3: Have system for almost a year, now. Had one leak when a hose cracked. Not sure whether to blame that on the company, or on my installation. Nevertheless, water is still tasting great and we've had no other problems at all with the system.

This is a great system if you want water that tastes as good as high quality bottled water. We had a whole house sediment filter that removed some of the "dirt" from our city water but it still had a chlorine taste so I got a single stage filter. That was a nice addition, it removed the chlorine taste and made the water more drinkable but it still tasted "off". So I got and installed a 3 stage filter. While somewhat better than the single stage filter, the 3 stage was still lacking what we were getting delivered in 5 gallon bottles for our water cooler. I can't give it a fair description but it was still just a little off. I was hesitant to pull the trigger on this full RO system for a few reasons. 1 being cost. I thought the filter replacement would be costly and frequent. Turns out it is only about $70/yr. Which is not bad for bottled water quality water any time you want it. Our water delivery is about $30/mo so this works out to be quite a bit cheaper. I was also concerned about the size of the system. With the storage tank and the 6 filters, this isn't a "small" system that you can tuck under a sink. Unless you have a giant area under your sink this does take up quite a bit of room. But for the quality of water this system produces, I feel it is worth the sacrifice. We just need to get a little more creative with how many cleaners and dust pans we keep under the sink now. And I've also seen people set this up in their basement and then run the lines up to the sink, which could also be an answer for some with space concerns. Overall I should have just installed this unit in the first place. It would have saved me about $400 in single stage and 3 stage filter setups. This is the one to get! Also there's a guy on YouTube that goes by "The Fixit Shed" who has an excellent installation video. If you've ever done any plumbing before, set aside 2-3 hours and you can just go step by step through the video. My only advice is the tubing needs to be well seated in the housings. Push those little suckers in as far as you can or you may have some leaks when you turn everything on. Other than that, I say get this system. It will magically transform your cruddy city water into great tasting healthy water right before your eyes!

This seems to be a decent unit. It replaced my old one easily. It was pretty easy to set up and get into action. Water seems to be decent tasting and clear. Sean did a great job in helping me get my extended warranty registered. Thank you!

This RO unit was easy enough to install. It provides great tasing water. Overall, we are very happy with it. The only thing I don't like is that the drain makes noise when it is working. It's a trickle water sound. It's not loud and I am sure I will get used to it. But I'm still at the point where I hear that sound and think the faucet is still running or there is a leak. This RO unit is pretty big. It takes up most of the space under my sink. It fits, but doesn't leave room for much else. I'm ok with that though, so no big. As for the drain "Saddle" that they provide with the unit. I don't trust it. I've used drain saddles before and they eventually leak. So, instead of using the drain saddle that they provide, I use a dishwasher drain Tailpiece with High-Line Branch for my drain. It costs a little more money and adds some time to the install, but in the long run, my method is surely not going to leak. It is definitely more reliable than the saddle piece provided with the RO unit. I added some pics of what I did. It's easy enough to install and gives me piece of mind. The other thing I really like with this RO unit is the automatic leak shutoff valve that they provide. It is an ingenious little device that give me a lot of piece of mind.

Filter system works well. Manual could be better but since it comes almost fully assembled and, and this is my third RO installation, it was easy enough for me. The sink faucet shipped with the kit seemed a bit flimsy and had a leak. I contacted iSpring support and representative Iris quickly sent me a more robust replacement.

I’ve wanted one of these filters for years now, once I learned a bit about the chlorine, fluoride, and microplastics in my tap water. While my wife and son drink water from our Brita pitcher, I normally would just drink from our kitchen sink where the water isn’t as cold and not as painful for my sensitive teeth. I drink about two pots of coffee a day, take 1/2 gallon of water with me to work each day, and drink probably another 1/2 gallon per day while I’m home. It’s a lot of tap water! When I first discovered these filters, we were renting an apartment, so it didn’t seem worth the effort to install. Once we bought our house, there were a million other things to spend money on first! 2.5 years since we moved in, a solid Black Friday sale coupled with our wedding anniversary finally made this purchase happen. I ordered it at 11:00am this morning, and it was at my door before 2:00pm same day. I ended up installing the filters in my basement, directly underneath the kitchen sink, to save some space. The water tank is under the sink, for now (I may also move that to the basement). Having the filters in the basement made the install a bit slower, having to go up and down the stairs a bunch, but all in all it took me about 2.5 hours to install. I needed a drill to mount the filter rack to the wall, but other than that the only tool I needed was a pair of channel locks. The process was straightforward, and there was no point in time that I was confused as to what my next steps were. The only thing that tripped me up was the reverse osmosis filter itself, but that was only because I didn’t fully seat it in its housing at first. Once I fully popped it in, the housing cap screwed on, no problem The push-to-connect fittings are very easy to work with, and I had no leaks once I brought the system to pressure. There’s even an included auto-stop valve that’s supposed to detect leaks and shut off the water automatically, which is a great peace of mind. The instructions direct you to visually check the install each day for the first two weeks. I’ll be doing that, but knowing that auto-stop is on there still makes me feel much better about things (I’m an electrician, not a plumber lol). Not wanting to use the drain saddle, I ran my drain line directly to the utility sink in my basement. I didn’t plan for it, but being able to physically see water leaving the drain is a convenient way to be able to tell if the system is actively filtering water in the moment, or whether the tank is full The water tastes great, better than the Brita in my opinion. I bought the version that has the Alkaline filter final stage to remineralize the water for taste, and I’m happy with that decision. Highly filtered water often tastes bland, but that’s not the case with this unit. I could fill up a bottle for some fancy spring water with this stuff, and I doubt anyone would notice there’s a difference Product quality seems solid, and the reviews lead me to believe it’ll all hold up for years to come. The faucet is a little wobbly, but I understand it can’t be too tight without risking failure. The flow rate from the faucet is perfectly adequate for a glass of water, too. Not as fast as the tap, but that’s to be expected. Tomorrow it’ll get put to the real test, when I fill up my 1/2 gallon water bottle and brew a pot of coffee. The reservoir tank supposedly holds 2.6gallons though, so I don’t foresee any issues. The rest of the family wakes up hours later, and the tank will no doubt be refilled by that point. On initial startup, the first tankful took about 1.5 hours to fill up. Per the instructions, I then poured that first tank out, presumably to remove any potential manufacturing contaminants. That waiting game for the first good glass of water was probably the hardest part of the whole install I’ve wanted one of these things for years. I finally purchased and installed one today, and I’m incredibly happy with the end result. I wish I did it sooner, but the next best time is today, right? The company seems to stand behind their products in terms of warranty and returns, and at such an attractive price, there’s really not much risk in giving this filter a shot in your home. I think you’ll be as satisfied as I am!

This reverse osmosis was packaged with great care, and it arrived without any damage. The instructions were amazing and made it easy to follow. There were even colors and pictures/diagrams so you know you’re assembling it correctly. The instructions are filled with tips likely based on other people‘s mistakes. These tips saved me a lot of time and heartache. After I was finished with the installation, I checked for leaks, and there were none. The water tastes delicious, and I’m so excited that it’s remineralized. Other reverse osmosis systems that don’t remineralize leave you feeling bloated. Whenever you drink the water, the faucet is classy and easy to use. The water pressure is as expected, and the water is completely clear. They sell packages of filters making it easy to change the filters when due.
