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

Relatively easy to connect hoses and everything in the correct order, but be patient because set up takes time. There is extra time to do the initial filter rinse, then you have to fill the reservoir tank and empty it twice, then you can drink after the third fill. But the time is well worth it, the water tastes great and it's a massive improvement from my tap water. One more thing I didn't know is that for every 1 gallon of drinkable water, 3-4 gallons of "waste water" is produced and that is the water that flushes your RO filter and makes your filter last longer. Even then it is still pennies to operate compared to bottled water. I have already recommended this system to all of my family members because it's absolutely worth more than the cost and time to install plus there's always clean water.

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!

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.

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!

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.

Ich habe lange nach einer zuverlässigen Umkehrosmoseanlage gesucht, da unser Leitungswasser hier sehr kalkhaltig und „hart“ ist. Gerade wenn man sich intensiver mit dem Thema Wasserqualität und Nährstoffaufnahme beschäftigt, merkt man schnell, wie sinnvoll ein solches System ist – und dieses hier erfüllt genau das, was ich mir erhofft habe. Die Installation war mit etwas handwerklichem Geschick gut machbar, alle Teile waren dabei und verständlich beschrieben. Besonders gefällt mir der zusätzliche Alkaline-Filter, der dem Wasser einen angenehm frischen Geschmack verleiht. Seit der Inbetriebnahme trinke ich deutlich mehr Wasser – einfach, weil es so gut schmeckt und man ein gutes Gefühl dabei hat. Für diesen Preis bekommt man wirklich ein hochwertiges System, das hält, was es verspricht. Absolute Empfehlung für alle, die Wert auf sauberes und gesundes Trinkwasser legen!

井戸水で使ってます。訳あって水質２６項目調査をしました。装置なしの時に雑菌が多少多いと判定されこの装置を取り付けました。そして調査結果は全てにおいて数値が合格となり（数値が少なすぎると言われました）この装置が圧倒的だった事がわかりました。アルカリの数値が高すぎるとのことだったので取り外しました。元々の水圧が弱いので水の出が悪いのですが（ポンプ付きを買えばよかった）タンクを使って上手くやってます。ネットで見て「これしかない」と思い買いましたが本当によかったです。
