Review: Excellent Performance, Value, Customer Support - 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
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.

## Questions & Answers

**Q: What does this mean: "For each gallon of clean water, only 2 gallons of water are wasted"? Where does the wasted water go? How is this economical?**
A: If your family drink 10 gallons of water per day. The waste water might equal to 10 flushes of your toilet.

**Q: Where do I get replacement filters and which ones do you need to change and when?**
A: Many online sources that sell RO systems. A search for the RO system itself will typically get you a list of a bunch of places that can also sell the filters. You can buy them thru Amazon in multiple versions.  Individually, 1 year pack, 2 year pack, 3 year pack. In a year some of the filters are recommended to be replaced twice, some once, etc. And the "pack" comes with the right number of filters for that period of time. Stage 1 (FP15) is a 10" sediment filter replacement recommended 3-6 months though in our house we have a pre-filter for the whole house so we don't replace this one as often. Stage 2 (FG15) activated carbon filter replacement recommended every 3-6 months. Stage 3 (FC15) CTO carbon block filter replacement recommended every 3-6 months. These three are in the 10" vertical tubes and are relatively easy to change. Stage 4 (MC1) is the RO membrane itself. Recommendations on replacing this are every two years but vary. We have a pre & post particulate monitor to help us tell when it's losing its effectiveness as this is the most expensive component to replace. Multi-year filter packs will include an RO membrane but a single year pack typically will not. Bear that in mind when looking at cost of 2 year vs. 1 year packs. Stage 5 (FT15) another carbon filter but post RO. Recommended replacement annual. Stage 6 the Alkaline filter that actually puts minerals back into the water. This is recommended to be replaced every 3-6 months. In my experience you will begin to taste when this one needs replacement. This stage is the reason I bought this particular RO system and I like the taste it gives to the water. IMHO it will diminish over time and give you some indication when it needs to be changed. If you search in Amazon under something like iSpring Filter Pack

**Q: what is the sie of the hole required (in the granite slab) for the faucet?**
A: I think there is some confusion with the answers here. I think people who are stating holes over one inch are referrring to standard size holes that are factory or site drilled., and are already there. The faucet has a larger than 1/2" excusion that should cover a larger hole. By all means if you need to drill your own hole, only make it 1/2", because that is all that is required.

**Q: is there a difference between this brand and other brands like tap water master?  why is the price gap so dramatic**
A: Since 2005, iSpring has brought the price of an average RO system down from $700 range. We bypass middlemen, sell direct online, cut advertising and live up with customers review by continuous improvements. We are doing what we want to do, that is, make clean water available and affordable to more people. We believe in long term value. So please let us know where we can improve, and write review to share your joy and experience. Thank you!iSpring Water Systems | (678) 261-7611 M-F 9-5 EST | sales@ispringfilter.com

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.

### ⭐⭐⭐⭐⭐ Great system and better customer support!
*by D***I on September 19, 2026*

Bought this after consulting with Kinetico and they wanted $3500 for basically the same system. Decided to try this and install myself. The videos and instructions made the installation easy and we were up and running in no time. The system has worked great and has definitely done its job very well. After having the system for about a year, one of the canisters developed a small pinhole leak. Luckily the automatic shutoff system worked as it was intended to do and prevented a huge mess under my sink. I reached out to Sean to get a replacement canister for the system and the response was extremely quick and over and above what was necessary given the situation. You just don't see this type of customer service very often anymore and as a consumer, I greatly appreciate his willingness to help get us back up and running with great RO water. Highly recommended - don't hesitate.
