Review: One of the best purchases I've made in a long time! - 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.
Review: No more bottled water! - 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.

**Q: does this unit remove asbestos crystals from the water**
A: It is like an egg can't pass cheesecloth. The size of asbestos fiber ranges from 0.1 - 1 micron, which is at least 100 times larger than the RO membrane pores at 0.0001 micron.iSpring Water Systems | (678) 261-7611 M-F 9-5 EST | sales@ispringfilter.com

**Q: How fast does it refill the tank I plan on using it to change my water in 2 40 gallon fish tanks will i have to do one tank a day?**
A: The tank is only for buffering.I think the flow should be OK to do at least one 40 G tank the day.Good unit ,Water is great

**Q: Does the tank contain a food grade butyl bladder? If so, does the bladder need to be cleaned every year? How do you go about doing that?**
A: Hi H. Friedman, Thank you for your question. You are correct and it has recently been updated. To clean the system and bladder is the same. Remove the filters and put 3 tbs of bleach (1 tbs in each vertical filter housing) mixed with water until the system and tank are full of this disinfecting solution. Let is sit for 1-2 hours and then rinse the system and tank twice. Please let me know if there is anything else I can do for you in the future. Thanks, iSpring Water Systems

### ⭐⭐⭐⭐⭐ Excellent Performance, Value, Customer Support
*by C***N on December 14, 2025*

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
