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

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.

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.

While this seems complicated, it is quite simple to understand and install yourself. The video provides excellent help. I have no leaks and no issues but I also slept well knowing that there is a built-in mechanism for leak detection and auto shutoff. Though I had only minor questions, I got immediate and friendly help from Robert who made me feel like a truly valued customer. Thanks for everything. I also did before and after tests (using a 21 test kit) and TDS meter. The results were incredible. The product does exceptionally well - as claimed. The water tastes so much better and I’m actually drinking more throughout the day. Not sure if I can ever go back now.

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!

The old Sears 2-stage carbon water filter wasn't good enough. It made the water taste better, but didn't remove the unwanted dissolved solids. We were still buying bottled water, which taste better. It was time to move up to a RO - reverse osmosis water filtration system! ► NOTICE - This product review was originally published on April 17, 2017, but it disappeared so I resubmitted it!

The cons: - I needed longer plastic tubing for our installation. The provided 10' lengths were too short. ◄ iSpring will provide longer tubing. - From the installation manual: Water pressure to the unit is no less than 40 psi. If it's below 40 psi, you will need to add a booster pump. If the water pressure is greater than 80 psi, you will need to install a pressure regulator. Our water pressure was above 80 psi, so this added to the system cost. - We didn't care for the provided brushed nickel finished faucet didn't match our fixtures. ◄ iSpring will work with you to provide a faucet that fits your installation. - Water is wasted to produce purified water. The ratio of brine - waste water to RO purified water is 2:1 to 3:1. Meaning 2 to 3 gallons of water is wasted to produce 1 gallon of purified water. ◄ For those that are concerned about wasted water. Also see my waste water recycling notes below. - Advertised - origin, China. ◄ for those that prefer to buy products made in the USA. Our installation: ▪ Our previous Sears filtration system was installed in the garage, so that was the logical place to install this filter system upgrade. This is next to the water heater ► cold water source & next to the washing machine ► a place to run the brine -waste water line. ▪ The purified water storage tank was positioned on its side in our installation, so it would fit on a storage shelf. ▪ I opted to purchase an inexpensive plastic tubing cutter, a PneumaticPlus TC nylon PVC PU plastic tube & hose cutter. Not required, but it cuts the tubing perfectly making the installation proceed faster. Here's the Amazon link: PneumaticPlus TC Nylon PVC PU Plastic Tube & Hose Cutter Cut Up To 3/4" OD (Drip Tubing Cutter) (1) ▪ I also purchased a TSPITOOL quick connect release tool, which is also not required, but does make releasing a connector much easier. In addition, it will set the lock in preparation for the locking clips. Here's the Amazon link: Quick Connect Tubing Release Tools For 1/4" or 3/8" Connectors (TSPITOOL) ▪ It seemed like a waste to toss the old Sears 2-stage filter housing, so I decided to retain it with different filters... sediment prefilters. Stage 1 is 20 micron & stage 2 is 10 micron, both sediment filters. The output of this 2-stage filter connects to iSpring RO - reverse osmosis stage 1, 5 micron sediment filter. ▪ To keep an eye on the system water pressure, I installed a water pressure gauge. This is VERY handy, as the reading drops when purified water is being produced & levels off as the purified water tank is full. After a few cycles, you have the normal readings. ▪ After the water filtration system had been in operation awhile, I started to wonder when the brine - waste water was flowing. My concern was a failed ASOV - automatic shutoff valve failure which could allow constant waste water flow. To provide a visual indication of brine - waste water flow, I installed a Rotameter LZM-15 flow meter. See my attached pictures. This flow meter won't work as it comes, but with a simple modification (see my flow meter product review for details), it will provide a visual indication of when brine - waste water is flowing. Here's the Amazon link: Uxcell a11120300ux0019 1/2" Female Thread 0.2-2.0 GPM 1-7 LPM Water Liquid Inline Flowmeter Rotameter LZM-15 ▪ We can redirect the RO brine - waste water into a recovery container so this perfectly good water can be recycled. During the summer the RO brine - waste water is used to water our raised bed vegetable garden & flower beds. During the winter we use the RO brine - waste water in the washing machine wash cycle. Closing remarks: ▪ Since this RO - reverse osmosis water filtration system was installed, there has been no need to buy distilled or bottled drinking water. ▪ The flow rate from our kitchen mounted faucet, about 15 feet away from the filtration system, is 0.5 gallons (1/2 gallon) per minute. ▪ System startup, first TDS (Total Dissolved Solids) reading: tap - city water = 100 to 98 ppm ► RO - reverse osmosis water = 3 to 4 ppm ▪ You will have to replace the filtration system filters in about a year... the RO membrane can last a 2 to 3 years (depending on the quality of your water source), so it's wise to start shopping around for replacement filters. These can be found reasonably priced, if you don't need them right away & can shop around. I have enough filters on hand for 2+ years. :) ► Update - June 7, 2017 ▪ The RO - reverse osmosis water filtration system has been working perfectly! Since we installed this water filtration, there been no need to purchase bottled water. ▪ On my recent TDS - total dissolved solids test. Tap water = 110 ppm & the RO water = 9 ppm. ▪ The city water... tap water TDS, shown above, is 110 ppm. The RO brine - waste water TDS is about 20 ppm higher. ▪ It's summer, so we're recycling the RO brine - waste water in the raised bed vegetable garden & to water the flower beds. ▪ We have to admit the amount of brine - waste water was a bit shocking, when we started saving it, but that is the nature of the RO - reverse osmosis water filtration system. 2:1 to 3:1... meaning, amount of brine - waste water >to> purified water produced. This isn't too bad if you can recycle the waste water! ▪ The city we live in calculates our sewer billing on the amount of water we use, so it makes sense to recycle the RO brine - waste water! ► Update - October 24, 2019 ▪ The system has been working perfectly, still on the original filter! The TSD has gone up slightly & the brine -waste water is running 3:1 or more, so the system filter replacement is on our to do list! ▪ I added a new picture of our six 5 gallon black buckets we use to save our brine - waste water to be recycled.

I’ve wanted one of these filters for years now, once I learned a bit about the chlorine, fluoride, and microplastics in my tap water. While my wife and son drink water from our Brita pitcher, I normally would just drink from our kitchen sink where the water isn’t as cold and not as painful for my sensitive teeth. I drink about two pots of coffee a day, take 1/2 gallon of water with me to work each day, and drink probably another 1/2 gallon per day while I’m home. It’s a lot of tap water! When I first discovered these filters, we were renting an apartment, so it didn’t seem worth the effort to install. Once we bought our house, there were a million other things to spend money on first! 2.5 years since we moved in, a solid Black Friday sale coupled with our wedding anniversary finally made this purchase happen. I ordered it at 11:00am this morning, and it was at my door before 2:00pm same day. I ended up installing the filters in my basement, directly underneath the kitchen sink, to save some space. The water tank is under the sink, for now (I may also move that to the basement). Having the filters in the basement made the install a bit slower, having to go up and down the stairs a bunch, but all in all it took me about 2.5 hours to install. I needed a drill to mount the filter rack to the wall, but other than that the only tool I needed was a pair of channel locks. The process was straightforward, and there was no point in time that I was confused as to what my next steps were. The only thing that tripped me up was the reverse osmosis filter itself, but that was only because I didn’t fully seat it in its housing at first. Once I fully popped it in, the housing cap screwed on, no problem The push-to-connect fittings are very easy to work with, and I had no leaks once I brought the system to pressure. There’s even an included auto-stop valve that’s supposed to detect leaks and shut off the water automatically, which is a great peace of mind. The instructions direct you to visually check the install each day for the first two weeks. I’ll be doing that, but knowing that auto-stop is on there still makes me feel much better about things (I’m an electrician, not a plumber lol). Not wanting to use the drain saddle, I ran my drain line directly to the utility sink in my basement. I didn’t plan for it, but being able to physically see water leaving the drain is a convenient way to be able to tell if the system is actively filtering water in the moment, or whether the tank is full The water tastes great, better than the Brita in my opinion. I bought the version that has the Alkaline filter final stage to remineralize the water for taste, and I’m happy with that decision. Highly filtered water often tastes bland, but that’s not the case with this unit. I could fill up a bottle for some fancy spring water with this stuff, and I doubt anyone would notice there’s a difference Product quality seems solid, and the reviews lead me to believe it’ll all hold up for years to come. The faucet is a little wobbly, but I understand it can’t be too tight without risking failure. The flow rate from the faucet is perfectly adequate for a glass of water, too. Not as fast as the tap, but that’s to be expected. Tomorrow it’ll get put to the real test, when I fill up my 1/2 gallon water bottle and brew a pot of coffee. The reservoir tank supposedly holds 2.6gallons though, so I don’t foresee any issues. The rest of the family wakes up hours later, and the tank will no doubt be refilled by that point. On initial startup, the first tankful took about 1.5 hours to fill up. Per the instructions, I then poured that first tank out, presumably to remove any potential manufacturing contaminants. That waiting game for the first good glass of water was probably the hardest part of the whole install I’ve wanted one of these things for years. I finally purchased and installed one today, and I’m incredibly happy with the end result. I wish I did it sooner, but the next best time is today, right? The company seems to stand behind their products in terms of warranty and returns, and at such an attractive price, there’s really not much risk in giving this filter a shot in your home. I think you’ll be as satisfied as I am!

I’m really happy with my new reverse osmosis system. The installation ended up being much easier than I expected. The instructions were clear, and everything I needed was included. The system works great, and I really like having cleaner, better-tasting drinking water right from my kitchen sink. Overall, I’m very pleased with my purchase and would definitely recommend it to anyone looking for an affordable and easy-to-install reverse osmosis system.

Very happy with my purchase, system works well and haven't any issues with leaking, water pressure etc. Love the "taste" of water, so pure compared to my regular kitchen tap. Hopefully it will help me to get rid of my skin issues that I have been experiencing due to poor quality in Perth, Australia. Edit: THIS Filter has saved my skin!!! I have managed to get rid of my extremely bad eczema which no cream / ointment could heal. 3 year update - still love the filters, I don’t drink any other water than my filtered water. It tastes great and has healed my skin! My filter housing broke before Christmas and I freaked out as I can’t be without it! i reached out to iSpring and they were fantastic to deal with! Shoutout to Francis, your help is much appreciated! Best system out there if you have digestion or skin issues! Thank you

I’m extremely impressed with the water quality from the iSpring RCC7-UV7. The difference is noticeable immediately — the water tastes incredibly clean, fresh, and pure. It has completely removed the chlorine taste and any odours, and I feel much more confident about the quality of the water my family is drinking. The UV stage gives extra peace of mind, especially if you’re concerned about bacteria. That said, installation is not quick or simple. It took around 4 hours to complete and definitely requires plumbing knowledge. If you’re not confident fitting it yourself, you may need to hire a professional, which could cost up to £400 depending on your area. It’s not a plug-and-play system — proper plumbing work is required. Overall, if you’re prepared for the installation effort or cost, the performance and water quality make it absolutely worth it. Highly recommended for anyone serious about improving their drinking water.

Compré este filtro sin bomba por error y no funcionaba, pero después de contactar con ispring y hablar con Nick, me enviaron la pieza de repuesto que necesitaba. Excelente atención al cliente.

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!

REF; RCC7AK 6 STAGE RO SYSTEM: Firstly, I would like to say that the customer service at iSpring is exceptional - Francis to be specific. I had a very minor issue that did not scare me away from this product nor create any annoyance re. installation. Francis quickly contacted and helped rectify a very minor issue I had, following up with me to try and rectify the issue asap - thank you Francis! Packaging & instructions/fitting: The box arrived well packed and packed so well that I would not expect damage during transit. Each item was in its own box and had very little movement. The items came out of the box easily and had no damage. Well packed. The instructions for the assembly and fitment were very detailed. If self-fitting this unit, you probably have some kind of idea about what you are doing so you may not need to use the instructions as gospel, but they do provide a very well detailed and easy to follow assembly instruction. The flow diagram was welcomed too. A nice quick reference guide to hosing. This helped me more than the instructions - I find visual instruction easier than detailed description instruction. Whether you work in fluid engineering or fancy the DIY challenge, the instructions supplied will certainly allow you to install with ease. It took me about an hour to install and commission/leak check. The unit (although it looks rather large) fits very easily inside of my 900mm wide cupboard. It even allows for space around the filtration unit and the reservoir for placing filter spares etc. It certainly surprised me with how well the unit fits inside of my cupboard. I expected to assemble it, offer it up to the cupboard only to find it was too large to fit and then need to send it back… but I could fit two RCC7AK 6 Stage systems inside of my cupboard. Perhaps it opens scope to add further filters elements onto this system in the future… Filters are easy to change. This unit comes with a filter housing removal tool to provide leverage on the housing. Install the filtration system above the base of your unit to allow ease of filter change. There is a detailed commissioning instruction near the end of the instruction so please do follow this for the correct initial start-up procedure to purge the pre-osmosis filters (ensuring you do not put carbon deposits into the RO (reverse osmosis) membrane. Supplied parts: During assembly, I happened to think to myself 'a 90 elbow fitting would be perfect here'... they had thought of that and supplied multiple fittings! More than I needed. The length of piping was perfect. I used about half of what was provided - even with a drain line that extended far down the waste pipe into the next cupboard (install horizontal and away from the u-bend trap to eliminate a dripping noise and potential backing up of sink waste into the drain-line in the event of blockage). All parts supplied fitted my standard UK kitchen (15mm comp / 1/2" BSPP) but I did use some PTFE between the threads just to seal them as the thread form is NPT and my kitchen is BSP (thread angles are slightly different and therefore do not mate perfectly). I have had no leaks in the week I have had fitted. Taste/Testing: The taste is incredible. It tastes pure and clean. No tang or bitterness. It tastes purer than the purest bottled water I have tasted. I will now avoid drinking water that has not been through my RO system. Bottled water at a push! I have (glass) bottles stored in the fridge filled with my RO water. Bottled water is nice... but iSpring RO water is second to none. I agree with another review here that I fill my bottle with this water and take it everywhere I go. See the images for the testing. I believe that these images speak for themselves. Obviously, the RO water cannot be TDS free due to the remineralisation process but down to 47PPM from 435PPM is an incredible job and there is a clear difference in the ‘clean’ taste even between RO water and bottled water. This is evidence enough that the water is truly forced through the osmosis filter. Alkalinity of this water is slightly higher (TAP is 7.66pH, BOTTLED is 8.70pH *Sometimes artificially raised using Bicarbonate of soda, RCC7AK RO is 9.72pH). Yes, I did calibrate my pH meter prior to use! I am yet to perform some detailed research into the difference a higher pH water provides but brief research suggests that it is easier for the body to consume. I will take higher pH being better for the body at face value at this point for this review. Overview: I would suggest that this unit is installed in every home for the sake of reducing the number of chemicals that are consumed through water. At the very least, bottled water should be consumed. Avoid tap water! For the small cost (yes, the cost of this unit is relatively low) this unit is 100% worth purchasing. Fitting is easy, it comes with a nice outlet for the water, water tastes incredible, and the customer service is outstanding. Every home should be fitting one of these units. And whilst you are at it... consider stopping using fluoride containing products such as toothpaste and mouthwash. Use fluoride-free alternatives. I have personally noticed positive differences with regard to dental/mental health. BUY the iSpring RCC7AK! – I was not provided any incentive to leave this review. All opinions are from my experience of using this product!
