iSpring RCC7AK, NSF Certified 75 GPD, Alkaline 6-Stage Reverse Osmosis System, pH+ Remineralization RO Water Filter System Under Sink, Superb Taste Drinking Water Filter

We had been living with well water for a couple of years and were very unthrilled with everything about it. It was tolerable with a filter going through the refrigerator and on the shower head, but not great. Then something went very wrong and I still don't know what. My white towels came out yellow after a wash telling me that what I had already felt was right something was wrong with the water. So finally the landlord put a filter on the main pump, which was shocking to me to discover there hadn't been one in the first place, and the towels stopped being yellow. But the water still felt and tasted gross. I was intestinally ill and didn't know why. And then my hair was ruined. The hair strands became narrowed to almost nothing. I had to cut it very short as it just looked like spider silk. We then moved and we're back on city water and it has started the LONG process to recovery. I'm giving this ridiculous detail to let you know how fully skeptical and freaked out I was about water in general. When we first tasted the water in our new place which is on city water (reports say it's some of the best in the country) we thought something was wrong with it because it tasted so different. It was fine, WE were tainted having been poisoned for 2 years. So we filtered it through the refrigerator and it wasn't bad. Then the fridge died. So I combed through different water filtration systems and tried one which arrived broken. Didn't find that out until I had been working on the install for an hour! BE SURE TO INSPECT ANY PRODUCT BEFORE BEGINNING AN INSTALL. I'm going to get a pillow embroidered with that... Anyway! Then a reverse osmosis system was recommended to me and our lives were changed forever. I went through many of the RO systems on Amazon & eBay before settling on imprint. Their video was informative and made me feel that I could install it easily. I was fortunate that a hole was already drilled in the counter for a soap dispenser which I wasn't using. So the only issues with installation and these could have been my fault were not being sure if the little blue clips could go in either way (they can!) and really making sure that the tube had been FIRMLY pushed in. They say to, but I was far too worried I would hurt the tube. Don't be. That suckered is sturdy! There are 2 other issues that I would say determine whether you can easily do this yourself. Physically, I will say I'm not in athletic shape. I have knee, back, and neck issues and vertigo when lying down. (I'm a wreck I know!) This made getting under the sink several times and lying on my back to tighten the faucet challenging. Not undoable, but not the easiest. The clips and all the hoses are explained and color coded very well. That part is very easy. But this is not a light unit. It's heavy which is great in that I really felt it was substantive! But, a little tough when I had to pick it up and put it on the counter several times. Did I mention my bad back as well? Anyway, it was all ready to go when we read the final step. Drill a hole into the waste pipe. Hmmm. I have a drill, but drill into a pipe? In a rental? And while they describe it and it seemed simple enough, the picture didn't look like my pipes. I was lucky enough that the guy who recommended an RO system in the first place was happy to take five minutes out of his day and come over and drill the hole. It was nothing to him, super easy. He actually put the hole into the garbage disposal waste pipe, BTW. SO! As far as installation: depends on your comfort level with drilling a hole into a pipe and physical ability for awkward spaces and kneeling, twisting, etc. I did it though! And that means most of you can too. But you might also want to get all the tunes connected and then hire someone to install it the rest of the way. Don't pay them for connecting those tunes, you can do it! And now the conclusion: How does the water taste? Well, there is just no comparison. Screw Brita and Pur and those 4th rate filters that aren't doing anything worthwhile and you have to constantly refill a horrible pitcher over and over. This water tastes like you think water will taste! Clear, clean, no aftertaste. Just... water! I wish there was a way to be able to bathe in it! And it's that good at room temperature! For those who chill their water just because it tastes better that way, you don't have to! We also were having to buy bagged ice from the grocery store because the fridge that died was also our icemaker and the new fridge didn't have one. That ice is gross. Seriously. You know that smell from the plastic bag that it's in and how it transfers to ice? Bleah! But, I didn't want to make ice cubes with trays as it's a bottom freezer so I would spill the water all the time! What to do... A friend living in an RV told me to buy an icemaker. I was skeptical because I thought it wouldn't work that well, but without giving that a review here, it does work! Bye bye bagged ice!! So now we have the greatest drinking water we've ever had coming right out of a little faucet in the kitchen sink and we can put it into our tiny ice maker to make the best tasting ice we've ever had! And let me tell you, if you think good ice doesn't matter, you are just crazy. What's the point of putting your favorite beverage over something that will make it taste bad? I mean forget any diet soda, that tastes so bad it doesn't matter, but a $65 bottle of Redbreast Irish whiskey? Mmmmmmm.

I purchased the iSpring RCC7AK 6-Stage RO filter out of necessity when I could not purchase a sufficient quantity of bottled water at the store due to the COVID-19 shortages. Before this, I drank only bottled water because my tap water is especially rusty and full of sediment due to old pipes in my neighborhood. The tap water also had a strong smell of chlorine, metallic taste and would smell funny if stored in the refrigerator for a few days.That is no longer the case! Now, thanks to this RO filter system, I get water from the faucet that is as good as, if not better, than the water I bought from the store. I figure I'm saving at least $25 a month in water costs, which will have the system pay for itself in way under a year. Plus, no more lugging gallons of water from the store or making unnecessary trips in search of water.The system is fairly easy to install, requiring only the most basic understanding of plumbing and hand tools, albeit it helps to be flexible to get under your sink. The instruction manual is helpful, and there are several videos on YouTube to walk you through the process. All I can really say is that there's a big difference between watching someone else do it and doing it yourself. In particular, the instructional videos make it seem easier than it is because they're not shimmying under a kitchen sink with three drain lines, multiple water hoses and electrical conduits for a disposal and dishwasher.I feel the one thing either missing from or not emphasized enough in the manual is that the storage tank can be stood upright or placed on its side. This was critical for me because the tank would not fit under my sink standing up, and I have a standard 36" cabinet under my sink. My drain setup may be most of the issue - you can see how complicated it is in the pictures. Of course, what little usable space I had under the sink is mostly gone, but that's a small price to pay for clean water.Another potential issue with the instructions is with how vague they are regarding the installation of the drain saddle. It is recommended that it be placed on a horizontal section of pipe to prevent the sound of dripping water, but that's about all it says. My suggestion is to put it on a horizontal section of pipe just past the P-trap, preferably with the hole pointing straight up. Not only does this eliminate the sound of dripping water, but this might also prevent your system from malfunctioning should you get a clog in your trap, and it's less likely to leak into your cabinets if the drain saddle doesn't seal perfectly. I may be wrong about this, but I also think the videos missed the part about cutting a 45 degree angle on the waste water tubing (black tubing) to prevent the line from being blocked if it is over-inserted in the drain pipe.The instructions also walk you through a system purge to clear the lines, tank and filters. I think a combined approach from the videos and manual worked best for me. As shown in one of the YouTube videos, I disconnected the line from the third stage filter to purge the first three stages separately from the rest of the system. Then, keeping the tank valve closed, I reconnected the system and purged the last three stages. This is especially important for the systems with the Alkalinity post-filter (Stage 5). I had to purge the last three sections for 30 minutes before the water stopped being cloudy from what I assume was excess minerals coming from the Alkalinity filter. After that, I opened the tank valve, let it fill once and drained it according to the instructions.As for the hardware, my main gripe is that not all the quick connects had pre-installed, color-coordinated clips. However, the box contained a bag of extra parts that allowed me to perform the installation. I'm not sure if this was an oversight or just the way it is supposed to be. There was some water in the RO canister when I opened it to install the RO membrane. I speculate that either my filter system had been returned (possibly explaining the "missing" clips) or that the system was pressure tested prior to leaving the factory. In any event, the purge process cleaned everything up.A few other minor gripes: The filter section could use some kind of handle to lift it and for holding it while tightening or loosening the filter canisters. Perhaps this is intentional to keep you from over-tightening the connections? Also, the mounting instructions seem like an afterthought. I really can't imagine anyone mounting the filter section under their counter. It is far easier to just slide it under your sink and rest in on the bottom of the first three stages or lay the system on its back.Also, I installed the faucet in an opening in my sink originally intended for a soap dispenser that I never used. I cannot imagine most people using the included mounting hardware for the faucet, so that seems like it should have been a separate option. If it's of any importance, the faucet that came with my system is brushed nickel, but my original hardware is chrome. The distinction isn't that noticeable and I don't mind it, but it might have been nice to have an option (if there was one, I was not aware of it).My system also came with a leak detector that can shut off the flow of water to the system if water starts to pool under the sink. My leak detector uses some kind of pulp material that absorbs water and expands to shut off the flow. It's very low-tech, but that may be a good thing. Some of the videos I saw showed systems with a battery-powered leak detector. Of course, batteries can wear out. Still, an option between the two might have been nice. I did not install the leak detector, so this is just an observation.Overall, I am very pleased with the system despite my concerns and observations. The system is simple and sturdy. The water is creates tastes great and looks crystal clear. My only regret is not having purchased it sooner.

We use well water and after testing, we found it is high in TDS in parts per million (ppm), around 450 ppm. Testing the water after we ran it through a leading water filter pitcher still showed testing results of 228 ppm. After we installed the iSpring RCC7AK, NSF Certified 75 GPD, Alkaline 6-Stage Reverse Osmosis System, pH Remineral, testing showed the TDS to be 17 ppm. WOW! We are so happy with these results! The water is delicious, and the ice is sparkling clear!After installation, the faucet did have a slow leak around the handle. I emailed customer service, and within a few hours, I got a reply back from Sean. He was very helpful! Within a few days, we received a new faucet. Thank you, Sean for your quick response.I would recommend this system whether you have well or public service water. The price was very affordable for this system, and the installation was a breeze.
