ISPRING 7-stage Reverse Osmosis Water Filter System RCC7AK-UV is based on our legendary best seller model #RCC7. Featuring an 11-Watt UV Lamp with Smart Flow Sensor Switch and Alkaline pH+ and mineral balls, this model is the most comprehensive Reverse Osmosis water filter system in the market. In response to our customers' reviews about the older model with the UV lamp that was constantly on, although the problem is still very common in today's market, we do feel the pain of our customers. Therefore, we have developed a new model of transformer that features an inline Flow Sensor. Whenever you turn on the drinking faucet and water starts flowing, the UV lamp is powered on automatically. It turns off automatically when water is off. This prevents a potential heat hazard and extends the life of the UV light bulb dramatically. ISPRING RCC7AK-UV generates clean filtered water for drinking, cooking, hydroponics, aquariums etc. The unit removes hardness, heavy metals, toxins, and many other tap water contaminants. The equipped 11-Watt UV Lamp makes this model more suitable for potential highly contaminated water source such as well or groundwater. The alkaline filter provides pH balanced drinking water for human body. You will enjoy great tasting water with beneficial minerals right from your tap at merely 3 cents per bottle.
  • Based on our legendary model #RCC7, featuring UV stage and alkaline filter to restore appropriate amount of minerals and raise pH to 7-8
  • This system is certified against NSF 58 for TDS reduction and the use of FDA food-grade material in all parts
  • Alkaline stage adds back appropriate amount of minerals and increases pH - endless great tasting home-made mineral water at merely 3 cents a bottle
  • Manufacturer direct sale - legendary brand, quality RO system, affordable and reliable
  • With its advanced 11-Watt UV filter stage, the RCC7AK-UV is suitable for filtering well water and other problem water sources like water from lakes and streams, a flow sensor switch turns the UV unit on and off automatically with water flow, saving power and lengthening the life of the UV lamp

Great product and delightful service.
Using this 7 stage iSpring RO from Jan 2017. Very happy. Recently we replaced the filters. Subsequently, the outlet pressure dropped. So while we were trying to figure out the issue, called iSpring. Sean immediately figured out and pin pointed the exact issue. It turned out the storage tank needed replacement. Sean went ahead and placed the order and followed up on text to make sure we received the new tank. Its couple of days now since the new tank has been working well. Thank you Sean.

    ISpring 7 stage good system
    Two years ago I installed it at my father's apartment and this month bought it for my house. The System gives a good quality water, I did my research, today the 7 stage system+UV is best what you can buy for $300. The installation is simple but the pipe connection should be done very careful, have to push pipe all the way in to make sure it connected right and there is no leak. Also I had a problem with water feed adapter during the installation, but with the help of Nick from ISpring Customer Support, this part was delivered and system is working.

      Best quality water right at home!
      We purchased this 3 years ago when my son was born for formula and this was the best purchase I've ever made. I quickly became a water snob and couldnt stand drinking from any other sources. (We are on a well but would of definitely installed in city water too.)We just recently had to replace all the filters and was missing a couple filters/fittings. I needed help and contacted Ispring for advice, we received the best customer support from Sean. Without even asking Sean sent over replacement quickly and we were back on track staying hydrated. Sean followed up with us multiple times and was very helpful, really do appreciate this company and recommend to everyone.

        Nick was very helpful
        After five years of smooth performance of my iSpring RCC7K-UV, the housing of the blue canister started leaking. I contacted customer service and nick was very helpful in identifying the probable cause. He sent me all parts needed to replace the broken housing. I am looking forward to receiving the parts and install them. missed my tasty water. will update the review.

              Just installed - - Working well - - Good support
              After a year of procrastination I finally have installed this RO system. It is working well at this point. I have only modest water pressure (35psi) here so have used an Aquatec ERP 500 permeate pump to assist the RO membrane in maintaining a workable water flow. You can see this gadget as a black cylinder in the photo below. With the permeate pump the output water pressure is exactly the same as the input pressure. And, no automatic shutoff valve is required as the permeate pump just quits working when the output pressure reaches the same as the input. And no brine water flows at this point. Our well water TDS measures at about 450 and the product water measures at about 50 to 60. I did learn though that the TDS from the first pint or so of water will measure somewhat higher (about 90) due to the alkaline remineralization filter. I had a number of questions about the performance and used iSprings online customer support several times and received timely and knowledgeable help from Francis S. I wondered how one could know if the UV lamp was actually on when drawing water and Francis told me to take a look in the dark. Good idea. The two plastic fittings glowed enough to confirm the lamp was working. You can see from the photo that this system is installed just outside our kitchen window as I did not want to clutter under the sink any more than it already is. I will build a cabinet around the system to finish the project off. Hope this helps - - Paul

                This product was somewhat easy but tricky to assemble, it comes with user manual which well descriptive but I wish if they would have provided a link of YouTube video on how to install. I didn't read the instructions properly and end up damaging all the O-Rings provided for membrane. I then contacted the helpline number talked with company rep Nick he was really nice and helpful. He instantly agreed to send me the additional O-Rings with all postage paid which means company backs their product with very well after sale service support. But noticed few improvement areas too... link in my house, I have pull stop box installed which is now a standard everywhere but this product comes with old feed water adapter which does not fit in pull-stop-box as both ends are male. Therefore, I had to buy 3/8 In and 1/2 out supply line + 3/8 In X 1/2 In MPT Lead-Free Brass Compression Adapter to make it compatible which is additional expense of approx. $17.00. Also, after installing this product I noticed it keeps on Dripping I checked the knob it was all the way closed. Please refer to attached photos if that helps someone during installation. What I like? - After Sales Service + Water Quality What I dislike? - Incompatible feed adapter, Faucet only comes in Steel color (I was looking for oil rubber color) + Dripping Faucet

                  I bought this system because although I have orlando city water I like to take responsibility into my own hands when possible and thanks to Ispring I'm able to do that. I loved it so much I bought it as a gift to my sister who has well water. Nonetheless the system is made to handle well water. As far as the taste of the water and TDS, the water tastes great even after owning it 5 months now and nearing a filter change. The TDS still measures low as bottled water. This undersink filter system has changed my life and I now drink more water because of it. We are made of 70% water after all. With all of that being said I did find a con which I didn't really like but finding the solution is a phone call away. It was with the installation diagrams and instructions having to do with the alkaline additive and the sterilizer connection. One contradicted the other. After some research I figured it out Overall I really recommend this system. It just performs.
