RCC7AK-UV, NSF Certified, 7-Stage Under Sink Reverse Osmosis Water Filtration System with Alkaline Remineralization and UV Filter, Patented Top-Mounted Faucet Design for Easy Installation

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.

I’m extremely impressed with the water quality from the iSpring RCC7-UV7. The difference is noticeable immediately — the water tastes incredibly clean, fresh, and pure. It has completely removed the chlorine taste and any odours, and I feel much more confident about the quality of the water my family is drinking. The UV stage gives extra peace of mind, especially if you’re concerned about bacteria. That said, installation is not quick or simple. It took around 4 hours to complete and definitely requires plumbing knowledge. If you’re not confident fitting it yourself, you may need to hire a professional, which could cost up to £400 depending on your area. It’s not a plug-and-play system — proper plumbing work is required. Overall, if you’re prepared for the installation effort or cost, the performance and water quality make it absolutely worth it. Highly recommended for anyone serious about improving their drinking water.

Since we installed the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage Reverse Osmosis RO Drinking Filtration System with the Ultimate Water Softener, Alkaline Remineralization, Booster Pump, and UV Filter, we've felt confident that our family is drinking safe, clean water. The installation process was straightforward according to our plumber, and everything needed was included in the package—no extra trips to the store or additional purchases required. The water tastes great, and everyone in the family has noticed the difference. A special thanks to Francis for his outstanding customer service. We had some issues registering the warranty, but with his help, everything was resolved quickly and smoothly. He was incredibly helpful and professional throughout the process—we couldn’t be more grateful. Highly recommend both the product and the support team!

Excellent product. Easy to install, read through the instructions and then follow them step by step. I installed the feed, drain and tap in that order to start as these are the only modifications to your system in order of difficulty and reversibility. After these it is a matter of putting the various filters into the pre-assembled filter unit and connecting it to the feed, drain and tap you have already put in. If you wish to vary the system it is easy to add or split the system so I have a pure feed and a mineralised feed but for a standard installation everything you need is in the box along with spares for virtually all pipework, you just need to provide a drill for the tap and drain fitting and a spanner to tighten the tap. A particular item is a feed cut out so if you get a leak the cut out is activated by the presence of water to cut the water feed and protect from leaks. Overall a great product.

Good but pricey. Tap is decent

I've long been aware of the concerns surrounding tap water quality in the UK. From chlorine taste to potential contaminants like fluoride etc., it's understandable why many people opt for bottled water. However, the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage system has provided a reliable and affordable solution to these issues. I've been using the iSpring RCC1UP-AK 100GPD Under Sink 7-Stage system for over a month now and couldn't be more pleased with my purchase. After experiencing persistent limescale issues with our previous Brita kettle, the iSpring system has been a game-changer. The water quality is noticeably superior, resulting in improved taste and a noticeable difference in cooking outcomes. Additionally, the system has significantly reduced our reliance on bottled water, making it a more sustainable and cost-effective choice. The installation process was straightforward, and customer support was incredibly helpful in guiding me through the registration for the extended warranty. Overall, I highly recommend the iSpring RCC1UP-AK to anyone seeking a reliable and efficient under-sink water filtration system.

We have been using a jug type water filter for many years, but needed something much better as we live in a very hard water area with loads of chlorine added, besides, it's not always the best tasting water. So I decided to go for the full 7 stage RO filter unit from iSpring and am pleased I did. The equipment arrived very quickly and was well packaged. I thought it best to have as much space for the unit as possible, so fitted the unit in a cupboards away from the sink, I felt this would work as I have the pumped unit and a longer delivery pipe should work well, which it did. Installation is not really a quick job if you want to make a tidy job, but it can be fitted quickly if needed. I did experience a few minor water leaks, but hay, there are a lot of places for it to leak, and I expect I twisted a few fittings during the installation anyway. By the end of the day, all was working great, water leaks sorted, and system flushed and clear. I have checked it a few times now and all is leak proof and working as expected. I would say the 7 stage unit is a bit top heavy, seems they add the extra units without re designing the brackets, so I added a couple of small shelf brackets and a couple of cable ties to make it more stable. I also have the UV unit, but be careful to mount the flow switch away from the unit slightly because it must be sensitive to magnetic forces as it often turned on without water flow and it gets quite warm if left on. It is easy to see when it is 'on' by looking for a little light escape from the plastic water fittings. Finally, communication has been great between me and iSpring, and they offed advice and help freely. Remember though, you might need a different water connection than the one supplied but iSpring will supply what you need, however I did make up an adaptor with a fitting from the plumbers shop to fit my 15 mm pipe work. Yes I would recommend this unit, and the water it delivers is great.

We have a private water supply, and where we live in the Scottish Highlands our water supply has high levels of tannin (peaty coloured water). UV sterilisation systems work less effectively in less than very clear water. Therefore, having an under-sink RO filtrations system offers an alternative approach to cleaning the water supply. I’ve fitted and maintained at least three under-sink ROs in the past. What I really liked about the iSprings RCC 1UP-AK 100GPD system was how much thought has been put into the pipework design - with each pipe colour coded and easily identified during the installation and commissioning process. The fitting instructions are very clear, and I’d also recommend looking at the installation videos on the iSprings website for further guidance and tips. The RO membrane (stage 4 of 7) does a fantastic job of removing the tannin colouration (and other impurities) from the source water meaning that the UV on the final stage (7), can do its job properly. Peaty water is generally a little acidic, and combined with the RO process can make the resulting filtered water even more acidic. Stage 6 of this 7-stage system is an alkaline filter that is aimed at rebalancing the PH closer to neutral (i.e. PH of 7). Another observation is that the electrical pump is very quiet. Once the under-sink cupboard door gets closed it’s really difficult to hear the pump operating - so there is no disturbing background noise. A final comment, I like the quality of the RO systems so much that I’m now going to purchase another of the same for a holiday home rental that we have nearby.

I couldn’t be happier with my iSpring RCC1UP-AK Reverse Osmosis Water Filtration System! As someone who’s been concerned about the quality of tap water, especially the fluoride content, this system has completely changed my peace of mind. I’ve always been cautious about the water we drink and cook with, and now I feel so much safer. Setting it up was pretty straightforward. The instructions were clear, and the system fit under my sink without any issues. After installation, I tested the water with a TDS (Total Dissolved Solids) tester, and I was amazed to see that the water was at a perfect 43 ppm – that’s incredibly low and means the filtration is working exactly as promised. For reference, my tap water had a TDS reading 155, so this system really makes a huge difference. The taste of the water is noticeably better. It's crisp, clean, and refreshing – perfect for drinking, cooking, and making coffee or tea. I feel so much more confident using it in all aspects of my daily routine. Overall, I highly recommend the iSpring RCC1UP-AK system to anyone who’s looking for a reliable, high-quality reverse osmosis filtration system. It’s a fantastic investment in both health and convenience. If you’re serious about water quality, this system will not disappoint!

Easy to install. Water tastes good. The UV lamp comes with 110V ballast - one would expect that the manufacturer would use a universal ballast 110/220V that can be used everywhere (since it is globally distributed by Amazon). In short UV does not work for me - unless I buy a 220V ballast.

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

Ok

La ósmosis inversa en mi caso creo que no fue buena alternativa en la CDMX la presión del agua no fue suficiente para llenar el tanque. Con el deposito en el 4 to piso. Por lo que tuve que colocar una bomba adicional. Pienso colocar una bomba para aumentar la presión. El desperdicio de agua es considerable 4:1 partes de agua a la cañería
