Some people are concerned that reverse osmosis reduces the water pH due to removal of minerals. Sometimes pH value may get as low as 4 to 5 if source water is hard. ISPRING RCC7AK is an upgrade model of our most popular under sink Reverse Osmosis system RCC7. It features the 6th alkaline stage, which restores alkalinity by adding small amount (30 mg/Gal.) of calcium and magnesium back into water. The pH value typically will be around 7 to 8 but depends on source water hardness. Sometimes another FA15 cartridge is needed if source water is very hard. It is designed to be user friendly and easy to install (search ISPRING RO installation video). The clear housing in 1st stage enables visual inspection of filter condition. It comes with the EU designer high-arc Brushed Nickel faucet that is heavy and costs $45 alone. Featuring 0.0001 micron TFC RO and 5 stages of filtration, it is capable to remove 97.2% of Total Dissolved Solid in water, including chlorine, fluoride, arsenic, lead, chromium and radon, providing you endless Mineral Water right from the beautiful faucet that shines your kitchen. It will not just provide your family the great tasting safe drinking water that beats bottled water, but also make financial and environmental sense.

We have been using this for a couple of months now and we love it. The faucet is nice and we also have the unit connected to our ice maker and we are enjoying great tasting ice water. We dont buy bottled water anymore. It was easy to install. I had a minor issue and contacted customer support. I got an immediate and very courteous response from Richard, who is awesome. He solved the problem and even sent me a replacement part he thought I might need. I highly recommend the product and the company that makes it.

Installation was overwhelming to me, so got Trionics Superior Water in St. Peters MO to do install. Brian and Rusty did a good job, they knew exactly what to do. Rusty advised that Ispring rcc7ak was a good reverse osmosis system and that I would be happy with it. Rusty also explained how to turn on and off the Water Feed Valve and the Tank Valve. Waiting now for tank to fill up and then will run it out and let tank fill up and then I can come back and let you know how I like the water. They also installed a Pressure-Reducing Valve on line from water main.

A great product that gives you good clean drinking water. Fits under the sink well and it was easy to install. Reasonably priced when you compare to large jugs of water or water bottles.

I bought this unit about 3 weeks ago. The assembly is pretty straightforward. However, during startup, I found that one of the connectors had a manufacturing defect causing a leak. I did contact the Customer Support online and in very few moments I got online response from Francis. After I described my problem, he immediately offered either in store exchange or to ship a replacement connector. I asked for a replacement to be shipped. Even when the shipment came from the US distribution center, it was received pretty fast and within 4-5 days! The Customer service is responsive and very Customer friendly :). The water system is delivering a great tasting water. I selected this system mainly because it has a final stage cartridge to add some of Magnesium, Calcium and Potassium, back to RO water. These elements are important and beneficial.

I needed a water filter becouse I had kidney stones before so I searched for it and found this device. There is a 7 stage filter too which use’s UV to sanitize water at last stage but I don’t know if UV is safe for this use or not and as we have someone whith brain tumor in family I didn’t choose the 7 stage one becouse I didn’t know anything about UV and didn’t want to put his health in more risk. Maybe it’s harmless too. So I chose the 6 stage filter and now it’s around 1/5 month that we use it and the taste and colour is very good. We asked somebody to come and install it and we don’t have any leaking problem so far. I am very pleased about my choice and I hope this review would help someone else.

We have been buying bottled water for drinking because our water here tasted wired and has lots of calcium. It’s very hard water we have in our city. I’m very happy of the quality of water I get out of it. Plus I’ve saved a lot of money. I think it’s the best investment so far.

Several of the connections leaked. replacement parts for most worked fine but now I don’t have backup replacement parts for in the future. I did have to go and get another part from a plumbing store and redo the top part of the tank that connector continued to leak even with the replacement. The water tastes great though and hopefully it will last a long time!

First, this RO system (RCC7-AK) has many nice features. The fittings where the tubing connects to the filter housings have removable, locking clips. So if there is ever a problem, the tubes can be “unplugged”, and then re-installed when the repair is finished. Very nice. Other systems I have had over the years do not have this feature, and once those tubes are plugged in, there is no way to remove them (at least not without destroying the tubing ends and the fittings). This system works well and was easy to install.BUT, there was one minor problem. After installation, when water was first applied to the system, one of the fittings at the end of the alkaline filter leaked very badly. It turned out that there were no locking clips on any of the places where the elbow fitting were attached to the filters. However, since the package came with a bag of spare parts and many extra clips, I was able to repair the leak easily. After replacing the elbow oon the end of the alkaline filter, and installing locking clips on the other filter ends, there were no more leaks and now the filter system works well.

Had this product delivered. It was packaged extremely well but when I took all of the parts out of the box it was rather intimidating. The instructions recommended a video to watch for installation and it made setting up our system a breeze! Not near as difficult as I thought it would be. We love the quality of water we get from this system!!I noticed we had a small leak in one of the l shaped inlet fittings so I called their customer service department. Nick mentioned right away this sometimes happens in delivery, and he would send me 3 additional parts just in case we ever run into issues down the road. Within 2 days I had the replacement parts and a complimentary insulated water bottle for my hassle. Something so small but it was refreshing to have such a good customer service experience. Would recommend this product and company to anyone! Nice did an exceptional job and has earned a lot of respect from me.

Way easier than having a water cooler take up space and hauling jugs; much cheaper too. Water tastes better to me than the $9 a jug spring water my parents buy. Install was a little harder than I thought it would be.

Hook up was pretty straight forward. I did open everything up before looking at the instructions, says your not supposed to touch the membrane with your fingers which i did, oh well. Nice little hookups I was even able to connect my ice maker with the extra parts included which was a bonus. Been in a month and a half, taste is good and my TDS meter says its doing what it is supposed too. I have a 20 micron whole house filter and water softener before this unit, this takes the salt taste out. Haven’t had it long enough to go through a filter change yet.

We are really happy with our purchase of the six stage iSpring reverse osmosis system. Water taste is excellent. The system itself was relatively easy to install. I do suggest that in addition to the paper instructions, you also look at a couple of Youtube videos to show how it is done. To install the faucet, I used a 1/2″ drill bit (for metal) to drill through the top of the stainless steel sink. To ensure that the bit digs in, you need to use a punch to create a dent where you want to hole to be.

Great customer service from Adam at iSpring. I accidently broke one of the fittings and Adam mailed me a replacement immediately. I’ve owned a couple different RO systems in the past and the quality of the filter housings and faucet are top notch regardless of the broken fitting. Definitely recommend the product and Adam in customer service.

Have been using iSpring RO system for the past 5 years. So satisfied with water quality and their services. The customer manager Nick is responsive and efficiently solved my issues with RO system.Will definitely continue to use this RO system.

The system has worked really well. The tenant residents say the water quality tastes very good. When the plumber installed it over 17 months ago, he commented that it had a very good water system with multiple stages. Thank you Nick for helping me in obtaining the water filter kit.

I have been using the system for two months now. The system was easy to install. I completed the installation myself in a few hours and that included the time I took to configure its position under my sink to maximize the amount of usable storage space after the unit was permanently mounted. The quality of the water is outstanding. Our local water supply currently fails public health regulations and this system filters the water to a level exceeding the health standards. I use the water for all cooking and drinking needs, including water for my puppy.Speaking of my pup, he shredded the owner’s manual and bag of spare parts that came wit the unit. Don Huie, at iSpring customer service was fantastic and has sent out rplacements of each.I am very impressed with the unit itself and the customer service from iSpring.

The faucet nut did not fit the treads, in fact the treads were not metric or imperial . I had to get a machine shop to make a new nut.
