iSpring RCC7, NSF Certified, High Capacity Under Sink 5-Stage Reverse Osmosis Water Filter, RO Drinking System, 75 GPD, Brushed Nickel Faucet, Patented Top-Mounted Faucet Design for Easy Installation

⭐️⭐️⭐️⭐️⭐️ Great System, Excellent Customer Service!I purchased the iSpring RCC7AK 6-Stage Reverse Osmosis System a month ago, and I’m very happy with both the performance and the support I received.Installation was pretty straightforward, even for someone who isn’t especially handy. The instructions were clear, and the parts were well-labeled.The water quality is outstanding — the taste is clean, crisp, and noticeably better than our regular tap water. I especially appreciate the alkaline remineralization filter, which adds healthy minerals back into the water and gives it a more natural taste compared to flat RO water.About a week after installation, I ran into a small issue with a slow leak at one of the fittings. I reached out to iSpring support and Nick was incredibly helpful — he walked me through a quick fix over the phone, sent me a replacement part just in case, and followed up to make sure everything was resolved. That level of service really gave me confidence that I chose the right company.The water pressure is good, the storage tank holds enough for our daily drinking and cooking needs, and the faucet looks nice and doesn’t drip.If you’re looking for a reliable RO system with an extra stage for remineralization — and top-notch support if you ever need it — I’d highly recommend the iSpring RCC7AK. Huge thanks to Nick for the support help.

The media could not be loaded. I ordered the iSpring RCC7AK 6 stage RO system after moving into a new home because the company that installed my previous system wanted to charge almost 3 times the cost of purchasing this from Amazon. I want to give a major shout out to Sean at the iSpring Customer Service Team who was very helpful and kind to me.First off, the hardware in my kitchen is mostly brass but the options on Amazon only offer a nickel finish or black matte faucet. I ordered the nickel finish option and planned to buy a third party brass faucet to go with the decor in my kitchen. To my surprise, when I called customer service, Sean was kind enough to send the antique brass faucet directly at no charge after showing my proof of purchase, without having to return the nickel faucet that came with the original order. This already put the company in my good books.Secondly, I consider myself a generally handy guy but had never dealt with anything plumbing related so I planned to pay a plumber to install the system for me. Sean was so nice and encouraged me to follow the youtube video instructions by scanning the QR code on the packaging and he was confident that i could install the unit myself. I must say the Youtube video was SPOT ON and everything works exactly as was explained in the video. The installation took me about 3 hours to complete but that was because I was extra doubtful of my ability and eventually I had a leak because I didn't fully tighten the inlet water fitting to my cold water line. When I fixed that and performed the initial system flush, everything worked PERFECTLY.Thirdly, the water tastes GREAT! No more having to purchase bottled water and the comforting thing is that the replacement filters cost WAY LESS than what the previous company from my old house would charge and these are readily accessible via Amazon. This makes things so convenient.Finally, I would HIGHLY RECOMMEND giving iSpring a try. They are a great company and really know how to take care of their customers. For those at iSpring reading this comment, please give Sean a raise and make sure he is commended for his great service and in making sure this homeowner is content and his wife is happy with clean drinking water at home! Thank you iSpring and thank you SEAN! You ROCK!!

Who knew I'd be glad there is no outlet under my sink?I bought this system after quite a bit of research because, without an outlet easily available for one of the much-more-expensive RO systems with a built in pump for high flow rates, this system seemed best for (1) ease of install and maintenance and (2) a straightforward remineralization option. Plus (3) it is relatively affordable, and (4) other reviewers have noted that the company is especially helpful with issues.So: (1) I did in fact install this myself with absolutely no prior experience with plumbing. I watched the installation video before ordering, so I knew I'd need to be comfortable drilling into my counter and sink discharge. In the end I got lucky and managed to get the faucet through my old sprayer hole in a 4-hole sink--I went ahead and updated the sink faucet to a sprayer model while I had the water supply shut off. Drilling into PVC was a new thing for me and I did have doubts several times because PVC is so slippery, but starting with the smallest bit and incrementing up one bit size at a time got me there! No leaks, and the rest of the install was absurdly straightforward plug-and-play, with most issues caused by my ancient plumbing (the hot water shut off under the sink has corroded, which didn't matter for the RO install but proved mildly annoying when replacing the main faucet).(2) More studies are needed on whether remineralization is better for your health, but I love the taste of the remineralized water despite hating my very hard pre-filtered water. I am fairly confident that I could easily bypass the remineralization step if desired. Being a massive nerd, I have subjected my guests to blind taste tests and they do choose the RO output as tastier than the unfiltered tap water but I think several would prefer the non-remineralized output, I am saving that experiment for when I have more time!(3) Turns out that this system outputs just the right amount of water for a hydrohomie household of 3. I wash fruit and veg with it, and fill all our water bottles for the day, plus fill water glasses when hosting small parties, and have not needed more capacity than the tank supplies. It's also super quiet, since it doesn't have an electric pump. I'm so glad I didn't stress about the lack of under-sink outlet because this more affordable option is actually perfect for my needs!(4) I did snap the tank valve on install which means I also get to weigh in on customer support. Nick was awesome! I tried using the online support form but the captcha thought I was a robot, so I called--Nick was patient and helpful on the phone, followed up promptly by email, and sent me two replacement valves that arrived in a few business days at no additional cost to me. Since this mistake on my end did put me back a couple of days on install, I will take this opportunity to recommend that you for sure follow the instructions not to overtighten the tank valve, which is clearly specified in the paper instructions but I wasn't thinking much about it because I'm a smaller person and rarely manage to overtighten anything. Good news is that even if you stall out a bit on the mostly straightforward install, it's super straightforward to turn off the RO supply and continue to use your usual faucet until you're ready for the next step. (The other adult in my household spent some time quite concerned that I'd need the whole house supply off while we awaited an emergency plumber, this is absolutely not a real concern!)Overall, if you're comfortable with a drill and a couple wrenches and have successfully put together flat pack furniture, and you check out your cabinet space/sink plumbing in advance, you should be able to install this yourself in a single day while still enjoying the use of all your other plumbing, and then you'll have plenty of lovely tasty water with no fuss. And even if you do manage to snap the tank valve somehow, you can still enjoy the use of all your other plumbing and also Nick will help, still no fuss!
