iSpring RCC7AK-BN 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

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 live in Myrtle Beach South Carolina where the water contains many undesirable minerals, chemicals, and the taste is rather bitter. I purchased the iSpring RCC7AK 75GPM 6 Stage RO system hoping for a better tasting healthier water alternative. We've not been disappointed to say the least. The system arrived two days after ordering and within a couple of hours after watching the installation video on YouTube I had the system installed. I flushed the filters and the tank has per the manufacturer instructions, and allowed the tank to fill overnight. The next morning, after flushing all the old water and chemicals from our coffee maker we couldn't believe the difference in our morning coffee. Much less bitter and much better tasting. The water coming out of the faucet is noticeably cleaner and more clear than the previous unfiltered water. I opted for the six stage system because I wanted remineralization added to the final product of the filtered water. We couldn't be more pleased with our system. I have not had it long enough to change filter elements, however, as easy as the filters were to install I'm sure the replacement process will be smooth and easy. I highly recommend this system not only for ease of installation and taste of the water but also for the price. I researched long and hard before purchasing The iSpring system and could not find a better system at this affordable price. Also, I want to thank Robert and customer service for assisting me and getting my system registered and the free 3-year warranty offered by the manufacturer. If you're looking for a reverse osmosis water filtering system you cannot go wrong with iSpring.

5-STAR WATER FILTRATION PERFORMANCE WITH NO LEAKS 5-STAR CUSTOMER SERVICE WITH LIVE USA BASED, KNOWLEDGABLE TECH SUPPORT I’d researched residential water filtration systems for a while. I kept coming back to iSpring. BEFORE YOU BUY: MEASURE YOUR WATER PRESSURE (PSI) AND TOTAL DISSOLVED SOLIDS (TDS/PPM) then contact iSpring and they’ll recommend the system optimized for your unique water issues. I purchased a ppm digital water meter for around $20 at plumbing supply store, ran my ‘cold’ sink water and wrote down my ppm. Install a water pressure gauge (psi gauge) which may require a plumber, or purchase a gauge with a female threaded end to connect to a garden hose or utility sink with a threaded faucet. Last resort is if you are on municipal water, call your city water department, provide your address and ask for the psi to your address, they’ll give you an ‘estimated’ psi range. Record your ‘static’ psi readings when no water is running in the building. A psi reading, when water is flowing, may result in a slightly lower reading (depending on how the building is plumbed). If you are in a multi-family dwelling, verify if you are on separate water meters, if not, try and take several readings at low water use times, such as early mornings before neighbors wake, then calculate the average psi. Call iSpring, give them your ppm and static psi readings. They will advise you on the correct system to meet your unique water ppm and psi readings. Low psi residences may require an iSpring system with a water pressure pump, whereas high psi residences may require a system with an iSpring factory preset pressure reducer. iSpring is engineered to provide optimum performance between 45-70 static psi. The closer you can get to 70 psi, without going over, the better the RO filter will work and last. iSpring provides 5-STAR product support. I called and spoke to Nick a customer support manager, a real U.S.A. based professionally trained tech support specialist who has the answers memorized and is not reading a script. Inside the shipping box flap is a QR code. I suggest you scan it and watch the highly produced installation video and use it often. Each installation step has individually wrapped corresponding parts with individual installation instruction booklets. Installation is fool-proof. When you install and begin cutting tubes, never cut with scissors, pilers, serrated blades or knife. Each locking clip has a tab, the tab must always face the tube and not fitting. I had no leaks first time out. Mount the filter metal manifold - with the 3 pre-filters - before you flush them, as flushing the system with water will add weight and make it difficult for one person to lift and mount it. I suggest getting some scrap 2”x4” lumber or brick pavers to rest the pre-filter canisters on while you mark your screw holes with your sharpie marker. Be certain to mount the bracket high enough to leave room below to remove the pre-filter canisters. Install mounting screws, check for fit, then place the system on a towel on the floor during the entire installation process to assure full view of all fittings and inspect for leaks. Hang the filter manifold as your last step, leave the tube slack and zip tie them out of the way. The 3 Pre-filter canister O-rings are loose fit into a groove and should be installed vertically into the manifold to prevent the O-rings from unseating while you hand tighten. Don’t lay the canisters down to install them. Once installed, stand the filter system on a towel on the floor, then begin the filter flush step as directed and watch for leaks. If leaks appear, use the wrench turning it slowly until the leak stops, then stop tightening. This prevents over tightening and leaking. iSpring systems are designed to operate in a maximum ambient temperature of 100 degrees F. For hot climates, I suggest purchasing 3M Company adhesive cupboard door stops. They are rubber pads with glue backing. Stick them on the inside of your frame so they contact the cupboard door and create a gap between your cupboard door and frame to allow air circulation. Hang a thermometer in the cupboard to be sure. After installing your iSpring system, the remineralization stage releases more minerals over time as it breaks-in, so your ppm will increase. Furthermore, your static water pressure (psi) has an inverse relation to remineralization. The higher the psi, the lower the minerals released. A psi close to 70 will increase system filtering, life of your RO filter and decrease waste water. CONCLUSION: From my experience: iSpring provides world-class product support and filtration system. My water system has no leaks, and is currently providing water, with minerals added, at 10 ppm. It is clear and delicious. iSpring is American engineered and backed by 'Nick' their expert live American-based customer support manager iSpring RCC7AK-UV All components tested by and passed/exceeded NSF/ANSI 58 Certified Standards iSpring will advise you on the proper system when you provide your water ppm and static psi readings and support you through your entire DIY installation

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 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.

The old Sears 2-stage carbon water filter wasn't good enough. It made the water taste better, but didn't remove the unwanted dissolved solids. We were still buying bottled water, which taste better. It was time to move up to a RO - reverse osmosis water filtration system! ► NOTICE - This product review was originally published on April 17, 2017, but it disappeared so I resubmitted it!

The cons: - I needed longer plastic tubing for our installation. The provided 10' lengths were too short. ◄ iSpring will provide longer tubing. - From the installation manual: Water pressure to the unit is no less than 40 psi. If it's below 40 psi, you will need to add a booster pump. If the water pressure is greater than 80 psi, you will need to install a pressure regulator. Our water pressure was above 80 psi, so this added to the system cost. - We didn't care for the provided brushed nickel finished faucet didn't match our fixtures. ◄ iSpring will work with you to provide a faucet that fits your installation. - Water is wasted to produce purified water. The ratio of brine - waste water to RO purified water is 2:1 to 3:1. Meaning 2 to 3 gallons of water is wasted to produce 1 gallon of purified water. ◄ For those that are concerned about wasted water. Also see my waste water recycling notes below. - Advertised - origin, China. ◄ for those that prefer to buy products made in the USA. Our installation: ▪ Our previous Sears filtration system was installed in the garage, so that was the logical place to install this filter system upgrade. This is next to the water heater ► cold water source & next to the washing machine ► a place to run the brine -waste water line. ▪ The purified water storage tank was positioned on its side in our installation, so it would fit on a storage shelf. ▪ I opted to purchase an inexpensive plastic tubing cutter, a PneumaticPlus TC nylon PVC PU plastic tube & hose cutter. Not required, but it cuts the tubing perfectly making the installation proceed faster. Here's the Amazon link: PneumaticPlus TC Nylon PVC PU Plastic Tube & Hose Cutter Cut Up To 3/4" OD (Drip Tubing Cutter) (1) ▪ I also purchased a TSPITOOL quick connect release tool, which is also not required, but does make releasing a connector much easier. In addition, it will set the lock in preparation for the locking clips. Here's the Amazon link: Quick Connect Tubing Release Tools For 1/4" or 3/8" Connectors (TSPITOOL) ▪ It seemed like a waste to toss the old Sears 2-stage filter housing, so I decided to retain it with different filters... sediment prefilters. Stage 1 is 20 micron & stage 2 is 10 micron, both sediment filters. The output of this 2-stage filter connects to iSpring RO - reverse osmosis stage 1, 5 micron sediment filter. ▪ To keep an eye on the system water pressure, I installed a water pressure gauge. This is VERY handy, as the reading drops when purified water is being produced & levels off as the purified water tank is full. After a few cycles, you have the normal readings. ▪ After the water filtration system had been in operation awhile, I started to wonder when the brine - waste water was flowing. My concern was a failed ASOV - automatic shutoff valve failure which could allow constant waste water flow. To provide a visual indication of brine - waste water flow, I installed a Rotameter LZM-15 flow meter. See my attached pictures. This flow meter won't work as it comes, but with a simple modification (see my flow meter product review for details), it will provide a visual indication of when brine - waste water is flowing. Here's the Amazon link: Uxcell a11120300ux0019 1/2" Female Thread 0.2-2.0 GPM 1-7 LPM Water Liquid Inline Flowmeter Rotameter LZM-15 ▪ We can redirect the RO brine - waste water into a recovery container so this perfectly good water can be recycled. During the summer the RO brine - waste water is used to water our raised bed vegetable garden & flower beds. During the winter we use the RO brine - waste water in the washing machine wash cycle. Closing remarks: ▪ Since this RO - reverse osmosis water filtration system was installed, there has been no need to buy distilled or bottled drinking water. ▪ The flow rate from our kitchen mounted faucet, about 15 feet away from the filtration system, is 0.5 gallons (1/2 gallon) per minute. ▪ System startup, first TDS (Total Dissolved Solids) reading: tap - city water = 100 to 98 ppm ► RO - reverse osmosis water = 3 to 4 ppm ▪ You will have to replace the filtration system filters in about a year... the RO membrane can last a 2 to 3 years (depending on the quality of your water source), so it's wise to start shopping around for replacement filters. These can be found reasonably priced, if you don't need them right away & can shop around. I have enough filters on hand for 2+ years. :) ► Update - June 7, 2017 ▪ The RO - reverse osmosis water filtration system has been working perfectly! Since we installed this water filtration, there been no need to purchase bottled water. ▪ On my recent TDS - total dissolved solids test. Tap water = 110 ppm & the RO water = 9 ppm. ▪ The city water... tap water TDS, shown above, is 110 ppm. The RO brine - waste water TDS is about 20 ppm higher. ▪ It's summer, so we're recycling the RO brine - waste water in the raised bed vegetable garden & to water the flower beds. ▪ We have to admit the amount of brine - waste water was a bit shocking, when we started saving it, but that is the nature of the RO - reverse osmosis water filtration system. 2:1 to 3:1... meaning, amount of brine - waste water >to> purified water produced. This isn't too bad if you can recycle the waste water! ▪ The city we live in calculates our sewer billing on the amount of water we use, so it makes sense to recycle the RO brine - waste water! ► Update - October 24, 2019 ▪ The system has been working perfectly, still on the original filter! The TSD has gone up slightly & the brine -waste water is running 3:1 or more, so the system filter replacement is on our to do list! ▪ I added a new picture of our six 5 gallon black buckets we use to save our brine - waste water to be recycled.

Simple and straightforward install instructions accomplished with very few tools. Everything needed was sent with the RO system. Clean water produced with no adverse tastes. Overall I am pleased with the system. Julius at iSpring helped with the extended warranty registration, surprisingly prompt and courteous help.

I’ve had for two weeks and I’m happy with purchase. Install was simple and the instructions were easy to follow. My spout began to leak instantly and saw another review stating the same. Went to their website which was easy to navigate and submitted a claim. Robert emailed me back within 12 hours and shipped me out a new spout within 24. Awesome customer service. Switched out spout and no issues. Taste is great.

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

If anyone is considering buying a good water filter, look no further! The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System is what you want. If you think you might need help, do not worry! The customer service is excellent! They will make you feel nice and comfortable when you contact them. I am not sure if I can find the right words to express how fantastic experience I have had with iSpring exceptional customer service! But let's start from the beginning (not from Adam and Eve though, do not worry! LOL). Why I have bought a water filter. Most people do not know that the mineral water sold in plastic bottles is not healthy at all. There are 7 types of plastics and plastic containers are marked with a triangle of three "chasing arrows", which encloses a number giving the plastic type. The plastics which are typically used to hold water but also soft drinks, juice, sports drinks, beer, mouthwash, ketchup, and salad dressing are made from a plastic marked as number 1. That indicates that those containers are made of Polyethylene Terephthalate (PET). Although that plastic is considered to be safe, it contains antimony, a metalloid element with toxic qualities, which leaches from PET. The rate of leakage increases with temperature and can yield unhealthy levels in bottles stored in higher temperature. Antimony can cause acute and chronic health issues, such as diarrhoea, vomiting, and stomach ulcers. Brominated compounds can also leach into PET bottles. They can irritate the skin, mucous membranes, and tissues. If you bear in mind that even though the levels of toxins leached from PET could be considered as on a safe level, they may accumulate in your system over a period of time becoming a serious health risk. That is why I decided to install a multilevel water filtration system at my home. Why I have bought iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System. The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System seemed to be the best offer on the market. It cleans your water from everything you need for a good price. I was not sure if I should order the system with or without the booster pump. I live in a big city and I thought the city water pressure should be strong enough to work with the system so I decided to go for the one without the booster pump. My buying experience. The order arrived quickly and before I even started installing the system, I received an e-mail from iSpring to thank for the purchase and to say that if the Feed Water Adapter (AFW) that taps into the cold water line did not fit my plumbing specifications, they would fully refund (shipping included) for the order of the AFWs that I needed. They included two links to AFWs which I could choose from. Once I ordered the AFW, I e-mailed iSpring customer service and almost instantly I was issued the full refund for my order! My installation experience. The installation of the system was easy. The package contained a very easy instruction with colour photos leading you through all the steps of the process. If you do everything as the instruction manual says, you will be fine. I did not have any problem at all, no leakage whatsoever. My surprise. Everything was fine but I noticed that my water tank stored only 2-2.5 litres of water. I wanted to use filtered water not only for drinking and cooking but also for washing fruits and vegetables and that volume of water was not acceptable for me. My contact with the customers service. I e-mailed customer service and they replied very quickly giving me a short check list. It was very easy to follow the instruction and give the system a check. The whole process took a couple of minutes. Further instructions made us come to a conclusion that my water pressure was below 45 psi and that was a problem. I needed a system with a booster pump. I was too optimistic thinking that my city water should be fine and I did not need the booster pump. Once we identified the problem, the iSpring customer service came with a solution. To make it easier for me and avoid possibly a bit complicated installation of the booster pump and its components on my existing system, they offered ordering a machine head with a booster pump factory installed. And here comes the best! As they understood that the water storage was of great inconvenience to me, they reduced the price of the machine head from 90 to 50 dollars! Since it had to be shipped from iSpring office in the United States, not the shop in the United Kingdom, where I live, that would generate some extra costs of shipping and the import tax. iSpring customer service offered me splitting the costs of shipping and the import tax! Solving the problem. My problem was solved. After installation the machine head with booster pump, the tank stores about 10 litres of water and that is what I need! I can hardly hear the pump working. The water pressure is very good and the tank fills up very quickly. The water tastes fantastic, much better than bottled water, no plastic aftertaste. My final thoughts. What else would you want from a customer service?! They could not do anything more or better! They are exceptionally kind, understanding, efficient, and professional! I highly recommend iSpring water to everybody. They are like a good friend, who is always around when you need them. I was very lucky having chosen iSpring and their product.

Compré este filtro sin bomba por error y no funcionaba, pero después de contactar con ispring y hablar con Nick, me enviaron la pieza de repuesto que necesitaba. Excelente atención al cliente.

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!
