iSpring RCC7P 5-Stage Maximum Performance Reverse Osmosis Drinking Water Filtration System with Booster Pump

This filter is excellent, the pump is very quiet, about the same noise level as a fridge running.Install was very easy and they include everything in the box, even the teflon tape and extra parts in case you need them.From my reading it appears like you can upgrade this 75gpd system to 100 gpd by changing the ro membrane to the 100 gpd one in the future as they are both the same size.Very happy with the purchase, takes my salty tasting well water and turns it into amazing tasting water.

We've had three RO units thus far - a Kinetico, which was ridiculously overpriced, then the very common Whirlpool WHER25, which is frankly a pretty good value and lasted for years until the spigot broke and we got a bad membrane, which kinda ticked me off. Now finally we're on to this model from iSpring, which is by far the best RO unit we have had yet. It was the easiest to set up, had the best instructions, and best overall workmanship. The chrome spigot is much more attractive than either the Kinetico or Whirlpool, and it does not have the annoying air gap that the Whirlpool used. To clarify - the WHER25 routed the waste water up to the spigot, along a parallel line to the drinking water. There was a small air gap inside the spigot base, and then the waste water continued on to the drain. I guess the point was to prevent water from your sink drain from backing up into the RO unit. Good idea in principle, until the air gap would start gurgling and eventually get plugged and leak water. Anyway, it's water under the bridge, so to speak, because the iSpring has no similar contraption for the waste line. You simply drill a hole in the kitchen drain line and attach the flexible train tubing, using the supplied saddle.I positioned ours in the basement, in an area right under the kitchen sink. I would highly recommend doing this if you can, because it makes the system so much easier to service, and it frees up space under your sink. I also installed a dedicated copper tee, gate valve, and riser for the feed water, rather than using the included adapter. This is not necessary, but it's a bit more elegant, and I can turn off the feed water to the entire system simply by operating the gate valve. If you know how to solder copper pipes, it's well worth doing. I had to buy some extra 1/4 inch tubing at the local Hommedeepot to get everything positioned where I wanted it in the basement, but I love this setup. So much better that cramming everything under the sink. See picture.Anyway, the system works extremely well. Our well water is pretty bad. It goes through several stages of treatment to soften it and remove iron, and it still has very high TDS. It's so bad that I'm embarrassed to say how high. OK fine, you twisted my arm... 1450 ppm! Yep, that's right - our water contains around 1450 ppm of total dissolved solids. So you're probably wondering what is the TDS after going through the iSpring? Drum roll please! .... 42! You read it right folks - the iSpring RO brought our TDS down from 1450 to 42. That's pretty impressive!This model includes an electric pump, which seemed like a good idea because low flow is a common complaint among RO users. The pump does indeed keep the water flowing at a steady rate, but if you're expecting it to come blasting out of the spigot, then you're expecting too much. Really, what the pump seems to do is to keep the flow rate consistent.This kit comes with everything you'd need to install it and then some. Extra fittings and bits and pieces in case you lose something, plus a water detection sensor which I have not hooked up because as you can see, my system basically hangs from the basement ceiling. If you install yours under the sink, then the water detector should alert you if something leaks.Anyway, nicely done, iSpring! Don't change a thing!

Installed in Jan 2021 on an old farm house with hand dug well. Had some initial performance issues. Don from customer service diagnosed the issue (site specific, high TDS), He proposed and shipped me a different membrane that arrived in a couple days. I can't say enough about how impressed i am with Don and Ispring customer service. The system has been working flawlessly on the same membrane (used for drinking/cooking water in the house) for two years - just looking at getting a new membrane now, as i feel its time. Would definitely recommend the product and the great customer service.

I purchased this sytem in order to free my wife and I from corporate bottled water, it's price and the space required for bottle storage. After our remaining supplies of water ran low, I installed this under the sink in very cramped quarters but was able to make it fit. I left the hoses long so the entire unit can be slid out for filter replacement. The system is very well constructed and installation was easy except for an issue with the supply fitting. The system comes with a fitting designed for 1/2" fittings but my faucet uses increasingly common 3/8 compression fittings. Made a quick trip to the local hardware store and picked up a 1/2 to 3/8 compression adaptor as well as a 12" 3/8 to 1/2 braided riser. Installing the adaptor onto the supply valve and connecting the riser on the other side allows this supply valve to be easily installed and located. Two or three wraps of teflon tape on these fittings will help ensure leak free operation.If you have the same faucet hook ups, order these two parts to install the system:Adaptor: Watts LFA124 Compression Male Adapter, 3/8-Inch OD x 1/2-Inch MIP Riser: Watts LFWTS-SPC12-68 Stainless Steel Faucet Supply Line, 12-Inch After getting the required hardware the entire assembly and installation took approx. 1 hour including drilling the porcelain sink (pick up the bit for this job when you go to the store if you don't alredy have one) for the faucet. If you don't have a 1/2" drill bit for ceramic, the following product should do nicely: Amico 12mm 1/2" Diamond Tipped Metal Hole Saw Drill Bit for Ceramic Tile Glass Upon charging the system water began to flow into the filters and eventually made it's way to the faucet as a black trickle due to carbon from the filters. Activating the booster pump doubled the flow rate through the system. Turning the faucet off resulted in the tank being filled in approx 20-25 minutes and this first batch was flushed out as per instructions.The resulting water is sparkling, crisp and superior in taste and appearance to the bottled variety. It will also save money in the long run due to very reasonable filter replacement costs. The sound from the pump is barely audible under the sink and only runs long enough to refill the tank (usually less than a minute or two).The YouTube video detailing the installation is far superior to the included instructions and is highly recommended.

Great system for the money. Very easy to install, this one has the booster pump (pump is recommended if on well water), it is so quiet you cannot tell the pump is running unless the room is completely silent. This one is mounted in the laundry room on wall that backs onto the fridge in the kitchen, running water to the fridge and also to island sink faucet in kitchen. Filter changes are easy to do, just make sure you remember to flush the first 3 stages of your system before water enters the membrane. The new filters have some loose carbon and you don’t want to push that into the membrane. If you need any tech support, Nick is awesome, always responds to online questions and genuinely cares about the customer. Good idea to watch the install videos on YouTube.
