iSpring RCC7U 6-Stage Reverse Osmosis Water Filtration System Review

iSpring RCC7U 6-Stage Reverse Osmosis Water Filtration System In The Spotlight.

Did you know in the United States that the EPA does not regulate private drinking water wells?

So you’ve got your own water well, you just want to make sure that the water from it will be as clean and safe as possible. This is common sense, people associate clean and clear water as being free from contamination. Well it is your responsibility to ensure your family is drinking safe water!

If you’re looking for something to make your municipal water a bit more palatable, then you might want to check out the iSpring RCC7U 6-Stage Reverse Osmosis Water Filtration System. Sure enough, you can keep buying bottled water, stocking your fridge with it, but in the long run, all you’re doing is waste money, not to mention the huge disservice you’re doing to the environment. Alternatively, you might get a distiller and boil away the solids from your water. This would, indeed, purify you tap water, but wouldn’t do much good against volatile chemicals such as chloramine, so you’ll be stuck with the awful-tasting water you had before.

Conversely, a reverse osmosis system (RO from now on) does a great job of removing these volatile contaminants, with the end result being fresh, great tasting water. Granted, there’s the issue of good minerals, or lack thereof after you hook up an RO filter, but on the flipside, we get most of our minerals from the food we eat, so it’s not that big of a deal. So, if you feel this covers the basics, feel free to read on and see why the 6-stage iSpring is such a good buy.


The iSpring RCC7U 6-Stage RO Water Filtration System is pretty much what it reads on the tin – it’s an RO system that purifies your water in six steps. One of these steps, or stages, is using an 11W UV light to kill off any bacteria, cysts, viruses and other microbial parasites in the water. The system doesn’t use any chemicals in treating the water, so there won’t be any chlorine or respective chemical byproducts. Coupled with the fairly high output (75 gallons per day), this makes the iSpring ideal for well water, though you could just as easily use it under your sink. Though, come to think of it, you might want to re-consider that if you haven’t got much space on your hands.

As of this writing, the iSpring RCC7U is available to order online.

A Closer Look


The way the iSpring RCC7U 6-stage RO system works is, first and foremost, by using the standard processes characteristic of these filtration rigs – it uses nothing but water pressure to filter out the contaminants. Of course, the first line of defense is made up of the carbon filters. Then there’s the reverse osmosis membrane so fine it’ll be as if you were straining hardboiled eggs through cheesecloth. It should take care of well over a 1,000 known water contaminants, including the annoying fluoride and chlorine, as well as pesticides, fertilizers and heavy metals.

On top of that, there’s another stage that deals with microbial contaminants by using an 11W UV bulb. This goes a long way to ensuring there are no viruses, bacteria, cysts or whatever else microorganism polluting your water – about 99% of living organisms in there should stop being so after the water goes through the RCC7U. It’s important to mention that the system does feature a smart flow sensor which turns the light on and off automatically, so you don’t have to worry about forgetting to do so manually. As soon as the sensor detects a flow, the UV light will turn on, and it will turn off again all by itself as soon as you turn off the tap.

As you might’ve guessed from reading the name, this is a 6-stage system, but there’s another that’s got 7 stages, with the balance filter that uses alkaline remineralization being the seventh. Both (either) come with or without expert installation, though you should keep in mind that it’ll cost you a pretty penny if you order an expert to go with your purchase. On a more serious note, though, the Ispring rcc7 can pump out up to 75 gallons per day, and every ounce of it will definitely be worth every penny you put into it.

Ease of Use

The full setup is rather large, and will take up plenty of space under the sink (about 14.5 x 5.25 x 17.5 inches, with the tank running about 16 x 11 inches), so be prepared for a major reorganization if you want it under your sink. Of course, the faucet is not the only thing you can attach it to; you can also connect it to your fridge output, coffee or ice maker, whatever jingles your jollies.

The older models of this filtration system didn’t feature a pressure switch, but they sorted this way back in 2014, so every rig made since then has it. Moreover, iSpring developed a transformer which packs an inline sensor switch, so you can convert your old system if you bought it prior to the 2014 upgrade. Better yet, at the time of writing, they are offering a 30% discount on the transformer if you’re an old customer (of course, you’ll need to leave your original order number if you bought it online, or show a receipt if you got it from a store to qualify for it). Please do your own checks to ensure these offers are still running.

Now, it’s important to note that the iSpring RCC7U generates a great deal of waste water – you can count with about two gallons of waste for every gallon of potable water. On the other hand, this is a high capacity filtration system, and the manufacturer does recommend you use it for well water, so you can simply use whatever goes out the waste pipe and use it to water your lawn, even some. Even if you’ve installed it under your kitchen sink, you can run a hose through the house or have some sort of permanent setup to do the same. Short of that, you might use it for washing clothes (provided the effluent from the RO is fairly mild) – this is preferable in an urban environment. Finally, you can just make a soak pit and let all the effluent from your RO recharge ground water. Simply leave everything to the filtering powers of the ground itself. The rejected water from an RO is technically not a pollutant, so you can leave it seep into the ground.

As far as actually installing the system goes, there are a few useful tips you might like to hear. Obviously, the first thing you’ll want is carefully read through the instruction manual. It used to be barely comprehensible, as if written in broken Chinglish, but iSpring has since stepped up their game and the manual is as good as any. Installing the system is pretty much like playing a game of sorting shapes, so if you’ve ever ordered something from IKEA, this should be a walk in the park for you. On that note, there are plenty of components, so you might want to lay them out and take a head count. Thankfully, everything is color-coded, which should make your job all the easier. Make sure you check everything and see if you may have gotten a faulty piece. If that’s the case, you needn’t worry about a thing – the customer support department will be on top of that. In case you’ve decided to install the iSpring under your sink, you’ll have to clear out a lot of stuff to make it happen.

Final Thoughts

With a 1-year money-back guarantee and lifetime support on top of the impressive filtering abilities, the iSpring RCC7U 6-Stage Reverse Osmosis Water Filtration System is definitely an offer too good to pass up. Add the amazingly helpful customer service, and you’ve got yourself a brand you’ll stay loyal to for year to come. The question is often asked what is the best ro water purifier you can buy? As tempting as it is to name a particular make or model, each that we review have their own merits, their own limitations and also have a wide range of price options. So what we would say is this cannot claim to be the standalone best ro water purifier however it can rank as one of them, especially if you have well water at home.
