iSpring RCC7 NSF Certified High Capacity Under Sink 5-Stage Reverse Osmosis Water Filter RO Drinking System 75 GPD

Fairly easy set up for me. The main issues for me were the leaks from the tubing and connectors. Once I figured them out, system was running and producing great water. The only other issue I had was with the leak detector fitting leaking. Julius said he would send me another one. I think this is a great feature. Read more

Works well. No leaks. No hard to remove and failure-inducing dust plugs on the unit as compared to a competitor's product. Instructions and illustrations are very clear; therefore installation was easy. Better quality fitments and a sturdier frame and filter housings than the competitors. Better filter cup and socket design (for the three pre-filters) than the competitors, so less chance of leaks. Appreciate the inclusion spare parts, even though I didn't need them now. All filters and the reverse osmosis membrane unit look identical to the competition's but without microscopic examination, I wouldn't know if they come from the same manufacturer and have different labeling or if they are also of better quality. I mention competitors only because I just returned one such unit after two weeks of struggle and bought this one instead. Read more

We purchased our 5-stage RO system back in 2016, and ran it without any issues until the end of 2023, when the system developed a significant leak, about 15 drops per minute if I recall correctly. The system was installed in our basement, so the water line was going to the refrigerator and the drinking water faucet, just above it. I preferred that setup, rather than installing it under the sink for several reasons. One, it would not use the under the sink space, and two, ease of access to replace filters etc. Consequently, the leak that was there, did not ruin anything in the basement because where it was installed, but, had it been under the sink, water damage would have occured to a degree. That being said, iSping provides a water detection alarm that should be strategically placed and checked regularly to notify the user in case of a leak. I glued a neodymium magnet to our sensing element and placed it on a ferrous surface so it doesn't move accidentally. Going back to the leak that developed. Upon reaching out to iSpring and describing the issue, Francis replied within a day with a diagnosis that the filter housing failed due to water pressure+age of the system. He recommended purchasing just the head assembly, which I learned was the filter housing with everything, except for the filters. New filters do not come with that purchase, but I was OK with that option, since I already purchase 3 years worth of replacement filters. The other reason why I would have replaced that entire head assembly or even purchased a new system was for the same reason you replace other things that come in pairs or more, namely, there is a chance another aging part could fail soon, or will perform sub-par. Upon delivery and installation, I noticed a leak in that system. Francis offered to send a replacment elbow connector, but that did not fix the issue. Francis concluded the head unit that was sent had to have some fault, so once again he helped by sending out a brand new head unit for me to install. I think all parts were shipped with FedEx, I just asked Francis to give me tracking info each time, so I can check the delivery date. Once that arrived and once it was installed, no leaks were present. The system was working as it was supposed to work and the TDS levels were good as expected, <20ppm. I was happy that iSping had such a customer caring service which did not give up until the customer's issue was resolved. My only experience with the customer service was with Francis, but his support was excellent. I have recommended iSpring RO systems to friends in the past based on the system performance. Now, I can say the customer service is also at a high standard. As a side note. While I was replacing the system, I also upgraded from the standard 3.5 gallon tank, to a 5.5 gallon tank. That was a good upgrade for our family, more ready-to-go water that is available at the given time. To sum it up, five stars for system performance, five stars for the customer service. I think the price is for everyone else to determine, whether this is good or bad, but from my point of view, iSpring systems are well priced and I would buy another system from them if I needed to. I didn't realize until I browsed their website, but they have many solutions for water treatments like whole house filtering etc. Anyway, for what it's worth, I felt my experience was worth sharing here for others to see after so many years of using the system.

After purchasing and installing a different brand that leaked, I am happy this iSpring product works. The instructions are great. The design is better quality. They have a QR code on the box that is a link to the installation video. Printed instructions are also included. The system is very similar to the one I had before for nearly 15 years, which made it really easy to fit under the sink, The included sticker to remind you to replace the filters is nice and I placed it on the inside of the cabinet door. In addition, the instructions show you how to pre-wash the pre-filters and very easy to follow. We have a water softener and have used an RO system for years. The water tastes great. Compared to the Express Water RO5DX Reverse Osmosis Filtration NSF Certified 5 Stage RO System with Faucet and Tank, that I bought and installed the week prior: Poor design, as it leaked from the start from the pre-filter containers. The instructions lacked details. They had one extra o-ring in the spare parts, but it did not work to prevent the leak. Needless to say, after installing the Express Water RO system I was frustrated. Uninstalled and returned the Express Water RO back to Amazon Read more
