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: Perfect RO system and great Customer Support - I decided to go for this RO system to replace my current rental RO system that I was renting for 4 years. It was basic and they kept increasing the price yearly. I did lots of research and settled on this system. It covers everything I am looking for in an RO filtration system to provide decent water quality for my family. Installation was easy and straightforward with the installation manual and video. The color coded pipes and connections made it even easier and foolproof. Water flow is decent and water tastes great. I checked the TDS. My city water supplied TDS is around 550 ppm, and the RO filtered water TDS is around 30 ppm, which is perfect (considering I have Alkaline stage, which adds back some minerals). I noticed that there is some over drainage from the filter. I contacted the customer support, and for my surprise, there was no waiting time or leave a message and we will come back to you! I explained my concerns to Nick and he went with me through the installation, guided me to check the tank pressure to make sure it is adequate, and to check the supply water pressure, doing some tests, step by step. I am an engineer, and I recognized that he is very knowledgeable and knows the system in depth. After monitoring and sending him the water pressure readings, it showed up that my main water supply is fluctuating and goes below the recommended water pressure, which causes the RO system to over drain. Nick proposed to send me a new RO system with booster pump, to compensate for the low water pressure, which I am grateful to.

**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

### ⭐⭐⭐⭐⭐ Best Water Solution for Me!
*by S***. on April 22, 2015*

First things first, I have well water and a whole house filter system in place that includes a sediment filter and chlorinator. The system was installed when I bought my home and the water tasted really odd, which I assume is because I had to add bleach to the chlorinator. There are mineral deposits on all of the shower heads and in the metal sink drains from the pre-existing system, which tells me that something isn't working very well to make my water pure. I have been buying Aquafina 24 packs of bottled water @$5 for years going through ~5/week that comes out to ~$25/week (unless the prices vary). I was gettin tired of having to carry the water into the house and having to recycle over a hundred plastic bottles per week. In addition to those bottles I was also buying 3 one gallon packs of distilled water for my coffee machine. I finally had enough and decided to sign up for water service from Crystal Springs, which to put it briefly was a total disaster. Every step of the process with this company was a struggle from the initial sign-up, through deliveries, to cancellation and picking-up equipment. I really don't recommend these DS water service (Crystal Spring) people if you have any alternative. Putting it in perspective, I spent less time setting up my iSpring seven stage filter than I did just on hold waiting to talk to DS customer service. With a little background established, I have to say that I had a fairly easy time setting up the filter system because I didn't have to drill a hole in my counter or sink. Instead, I elected to remove the handheld dish sprayer from the side and utilize the existing hole for the filtered water faucet. This was a bit of a hassle for other reasons than the installation of the filter, particularly that I didn't know how to take the sprayer apart for removal and then I reassembled it incorrectly. I will be replacing my main faucet with a sprayer style built in to resolve the lack of a sprayer for my dishes. The entire installation too me around 2.5 hours with some interruption and sprayer complication. I cycled the system per the instructions to flush out the tank and filters. The water initially was a little cloudy after purging and refilling, so I flushed it again to be safe. The water was a little clearer and tasted pretty good over the pre-filtered state. I left the tank overnight and had a glass of water the next morning and noted a very odd taste and smell to the water. Before purchace, I read several reviews of the system and was concerned that I was getting stage 7 (untraviolet light) contamination as others have indicated they experienced. Per other reviews I tried filling and emptying the tank a few times, but after a few hours it seemed like the water started to taste nasty again. I was about to return the system and chalk it up to another failed venture, but I decided to give iSpring customer service a chance to see if there was another possible culprit. They said that the tank is to blame because of the bladder that it inside of the standard tank. It is some sort of plastic or rubber material that some people are more sensitive to thank others. They suggested that with regular use the taste would even out and become more balanced, but I'd already tried emptying out the tank several times with no improvement in taste after a few hours of sitting. They offered to send me a new "special" tank that is redesigned for people that are sensitive to the other tank. I accepted the replacement tank offer and waited for it to arrive. They said that I could use the system with the tank turned off, but the flow of water was almost nonexistant, so it was pretty unrealistic to use the system without the pressurized tank. It took ~4 days to get the new tank and just a few minutes to install it, but WOW what a difference! The water is no longer cloudy and the smell is gone. This now meets most of my water needs since I can fill drinking glasses and my BPA free water bottles for when I'm in the office or on the go. Thank you for the replacement tank iSpring, please consider including this tank by default on all of your newly purchased kits. I saw that you've taken customer feedback into consideration with the untraviolet light portion by adding the pressure switch to the kit based on customer feedback. I'm certain that all new customers will appreciate the "special" tank as a part of their kit, even if the cost is increased slightly. After everything that I've been through just trying to get clean water, I recommend this system to anyone wanting a better alternative to bottled water or terrible delivery servce.
