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: Easy to install, great water - 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.

## 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

### ⭐⭐⭐⭐⭐ the best fit for my needs and affordable too!
*by J***. on July 30, 2025*

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!
