This system works great. I'm very happy with the change it made in our drinking and coffee machine water. The installation was relatively straight forward using the quick connections. I did not install under my sink, I installed it our basement. We have very hard well water. The water plumbed to our kitchen sink is very high in calcium. The calcium deposits wreak havoc on our built-in coffee maker and refrigerator/ice maker. I read that these deposits can reduce the longevity of the filters. I installed it in our basement to allow me to use soft water as an input to the system. I also connected the output directly to the pre-existing copper t-connection that is located in the basement to feed the refrigerator/ice maker and built-in coffee maker in the kitchen. The TDS level of our hard water is 369. the TDS level of the reverse-osmosis water is 35. The water tastes great and the ice cubes are crystal clear. I no longer have calcium deposits on our refrigerator door or in our built-in coffee maker. This is a great solution to our hard water problems!

I purchased this RO system and love it. One problem with this system though is that the water delivery rate is pretty pathetic even with a booster pump. That is in large part due to the small tubing that this system utilizes, which really chokes down the flow rate (1/4 inch tubing). I modified it to provide much better water flow/pressure. I purchased the iSpring T20M, the 20 gallon water storage tank, which was a bit pricey, but provides great volume. Next, I used 1/2 inch PEX pipe to plumb from the 20 gallon tank to my kitchen faucet. I inserted a "Tee" into this PEX line from the outlet of the Alkaline Filter to feed/pressurize the 20 gallon tank. I removed the cold water supply from the kitchen faucet, and replaced it with the PEX connection to the 20 gallon tank. That way, when I turn on cold water on my kitchen faucet, I have RO water. The hot water at the kitchen faucet is direct from the well (unfiltered), but I don't drink hot water. Also, with the 1/2 inch PEX, there is no real flow restriction, so the pressure at the tank is the pressure at my faucet, which is pretty good. I also supplied my refrigerator ice maker from this system, and the ice cubes are nice. Last, I put in a TDS monitor - my home is on a well, with TDS in the mid 500's, which is not the healthiest water to drink. The TDS measured on the outlet of the RO system is in the upper 20's to low 30's. In the future I'm thinking of putting in a small pump in the line with the "Tee" to increase the pressure supplied to the 20 gallon tank. That would give me great pressure at the faucet, but the pressure is pretty good now. I'm also thinking of putting in a small hot water tank on this system to feed the dishwasher. Feeding the dishwasher with RO water would make it last forever. Overall, I really like the RO water this system provides, very healthy, and tastes great!

Happy with this RO system. We moved to a house on well water and my wife wanted to have it tested. It came back showing very small amounts of uranium (2ppb). We bought this filter and had it retested and it came back under 1ppb. I recently noticed it was failing to cycle off and called the company to trouble shoot. They were able to figure out that it was probably the high pressure switch failing to turn the pump off once the tank was full. We were about a month past the one year warranty but they sent a new switch anyway. Very happy with it for a cheaper system and the customer support is fantastic.

***Followup Rating 04/22/18*** I've just replaced filters 1-3 and filter 6. Wasn't difficult to do and it took me about a half hour to complete. I'm still extremely happy with my iSpring system. I can't believe I went without this RO filtration for as long as I did. I'm going to install another system in my summer home so we can continue to enjoy fresh tasting and crystal clear water. I still award this product 5 stars. I absolutely love it. *********************************** Spectacular filtration system. I installed this in my kitchen sink with my fiancé. If you're willing to take an afternoon to do some tinkering, it's really not hard to install. We've been enjoying the delicious, crystal clear water from our filter for about 6 weeks now. I will NEVER go back to bottled water or a bubbler. Moreover, as a resident of Houston (which is surrounded by superfund hazardous waste sites, many of which were affected by Harvey), we are particularly thankful to remove a significant amount of potentially harmful chemicals that have been detected in the water here. Added bonus: the clarity of the water produced has also been noticeably beneficial for our espresso machine. Calcium and mineral buildup is no longer an issue.

We ordered the RCCP7-AK in an effort to reduce use of bottled water. Packaging was on point and installation was super easy with no leaks. I had to install my unit in the basement and feed the sink faucet and fridge. The original installation required a “tee” and other quick connect fittings. I called customer service and spoke with Nick regarding my needs. Nick offered to supplement the system with the parts needed in order to get it up and running. I installed the parts and noticed the 1/4 inch line suffered pressure loss. I spoke to Nick and was advices to move to 3/8 in tubing. Again Nick exceeded expectations by sending parts needed to get the filter up and running for my environment. They larger tube fixed the pressure concerns and the system is working flawlessly with no leak and tasty water.

Arrived in good order and fairly easy to hook up. I will make a couple of points that is not clearly written in the instructions. One being that you need to push the colored lines all the way into the female end until you feel it "set" into place. This will eliminate any hose leaks once you turn the water on. Second would be to make sure the elbow connections from filters 1,2, and 3 are tight prior to setting up anything. In my set up I had to separate the number 1 filter by removing the small black box (power for motor) then unscrew the 4 set screws and replace the elbow joint as it was leaking substantially after turning on the water. Taking these steps prior will save you a mess and aggravation. Now the unit itself is wonderful and water quality prior to set up was 206 ppm and after we are at 40 ppm. This is a significant reduction in harmful pollutants in our water supply. So the filters are doing their job and we are once again off the store bought bottled water. Installation took me about 2 hours from start to finish and I also had to rerun the line to the fridge/ice maker. Overall easy to install and would recommend this unit. If you have any question on your water pressure I would highly recommend getting the this model. I was on the fence due to the added increase in price but the pump has been used since I plugged it in answering my question whether I had enough pressure already or not. These systems need plenty of pressure to operate accordingly so if you have low pressure make the correct choice. Good luck and enjoy a glass of clean water. :-)

We have city water and it's safe but has a very distinct taste and chlorine odor even with our fridge carbon filter. The RO unit came with all parts for installation and took me about 45 minutes to install. Instructions weren't the greatest as there weren't enough pictures and they didn't line up with the instructions. The Diagrams were pretty good though and as long as you understand the flow it was an easy install. Watching the installation video also helped. Before running water through disconnect the tube right after the 3rd stage and connect one of the other longer tubes and flush out the filters. You'll see a lot of carbon and filter residue come out. Run it til it's clear and then connect the hoses back up. I chose not to screw it to the cabinet as it was really stable just sitting on the 3 filter housings. I pushed the water jug against it to secure it further. Pressure is really good going to the faucet. I ran a line to the fridge 20 feet away and the water pressue does drop significantly. Ice maker still works (newer samsung) but takes a while to fill a a glass of water. Going to trim all the hoses and add some air into the tank bladder to see if the pressure improves and if not will have to install a delivery/demand pump. Didn't run any tests but it did pass the most important test, the wife test. she's very particular about any off tastes in water and so far no complaints from her.

Unit installed quickly and easily. Small snafu with faulty check valve at first but with some expert assistance from Nick and a new part, the unit was back up and running perfectly very quickly. My unit is mounted in the basement close to and after the water softener, but it runs absolutely silent. You have to place your hand on the pump to know if it is running. There is always plenty of RO water available. The RO tap is mounted in the sink upstairs alongside the sprayer (drilled the sink). It works out perfect for drinking, making coffee, etc. TDS at the output is about 32 ppm (includes alkaline filter) with nearly 570 ppm at the input side! No odors, colors, tastes, etc. Ph seems to remain pretty constant from input to output at 8.5. Salinity at the input is 400 ppm and at the output is only 26 ppm.

Easy to install, quiet, and efficient. The alkaline filter very little TDS (18) and still leaves the water below 6.4 ph. Adding a second alkaline filter didn't change the results. Despite the RO booster pump, these units have a >40psi shut off pressure for the tank(s) which can be a little low for delivery. At the 37 psi I'm getting out of my tank, my ice maker isn't working right. ISpring recommended a second booster pump (that they don't sell) to resolve the low pressure issues. Its a shame, I don't have this problem with the 45 psi used for the input, you should be able to adjust the output pressure. Installed in the basement on the floor joists between my sink and refrigerator, and used metal pipe straps to hold the tank between joists which holds it nicely and out of the way. Since its also by the stairs, everything is easy to access. and installation took a little over an hour, which included removing some old filters and running a new line to the sink. I now have the best water ever coming out of both my sink tap and ice cube maker. Comes with everything you need for a standard installation, and spare parts - but I would recommend also buying a few shut off valves to make life easier when changing filters. Easily expandable if you find you want other features, I added a T before the alkaline filter and added a deionizing filter with a third output for 0 tds aquarium water and cleaning purposes - the possibilities are endless. Disclaimer: I did not need to use, or try, the feed line or drain taps, as I used existing ones.

I've owned my iSpring RO system for a little over a year now and I can say myself and my family are incredibly happy with it! It makes a significant difference in water quality and we love the taste. Changing the filters is pretty easy and seeing how nasty my sediment filter is after ~8 months really makes me grateful I have this filter (and that's just one stage!). The pump also isn't very loud and doesn't bother me any and even if it was it doesn't run all that much for us. We're on city water that isn't great quality and you can't tell at all after the water's been filtered. Before the system I usually see ~400ppm, but after filter it's usually right around 20ppm. My filters are due to be changed based on the 6 month recommendation, but I just did a quick test and still seeing the 20ppm along with the taste I expect. Last time around I changed my filters around when I started noticing the water taste a bit different and that was at around 8 months of use. I'm super happy with the support I've received from iSpring as well. I've reached out to iSpring support twice and both times Nick was super helpful and informative. You can tell they stand behind their product and want to make sure you're satisfied with your purchase. Even going as far as replacing the faucet for me for an issue which I don't necessarily believe is a fault of the product itself but rather my water. I reached out about waste water when I first purchased the system too as I was seeing ~4.5 gallons of waste per 1 gallon of filtered water and Nick recommended a permeate pump. I ordered one right away and would definitely recommend anybody that owns an RO system to get one as it improves the overall efficiency of your RO water system. It improves RO efficiency and reduces waste, which in turn reduces the time it takes to fill your jug and also helps to extend RO membrane life. I don't pay much for water in my area so it's not like I'm saving money by reducing waste, but to me just improving the efficiency of something is worth the $50 I paid for my permeate pump ( "Aqua Tec ERP-1000 Permeate Pump" on Amazon). I've already recommended this filter to a few people and can say that 2 of them are now owners of an iSpring filter and seem to be as happy with their purchase as I am. I will gladly continue to recommend this to friends and family and if I'm ever in the market for another water filter I will gladly buy another iSpring filter.
