iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction

REF; RCC7AK 6 STAGE RO SYSTEM:Firstly, I would like to say that the customer service at iSpring is exceptional - Francis to be specific.I had a very minor issue that did not scare me away from this product nor create any annoyance re. installation. Francis quickly contacted and helped rectify a very minor issue I had, following up with me to try and rectify the issue asap - thank you Francis!Packaging & instructions/fitting:The box arrived well packed and packed so well that I would not expect damage during transit. Each item was in its own box and had very little movement. The items came out of the box easily and had no damage. Well packed.The instructions for the assembly and fitment were very detailed. If self-fitting this unit, you probably have some kind of idea about what you are doing so you may not need to use the instructions as gospel, but they do provide a very well detailed and easy to follow assembly instruction. The flow diagram was welcomed too. A nice quick reference guide to hosing. This helped me more than the instructions - I find visual instruction easier than detailed description instruction. Whether you work in fluid engineering or fancy the DIY challenge, the instructions supplied will certainly allow you to install with ease. It took me about an hour to install and commission/leak check.The unit (although it looks rather large) fits very easily inside of my 900mm wide cupboard. It even allows for space around the filtration unit and the reservoir for placing filter spares etc. It certainly surprised me with how well the unit fits inside of my cupboard. I expected to assemble it, offer it up to the cupboard only to find it was too large to fit and then need to send it back… but I could fit two RCC7AK 6 Stage systems inside of my cupboard. Perhaps it opens scope to add further filters elements onto this system in the future…Filters are easy to change. This unit comes with a filter housing removal tool to provide leverage on the housing. Install the filtration system above the base of your unit to allow ease of filter change.There is a detailed commissioning instruction near the end of the instruction so please do follow this for the correct initial start-up procedure to purge the pre-osmosis filters (ensuring you do not put carbon deposits into the RO (reverse osmosis) membrane.Supplied parts:During assembly, I happened to think to myself 'a 90 elbow fitting would be perfect here'... they had thought of that and supplied multiple fittings! More than I needed. The length of piping was perfect. I used about half of what was provided - even with a drain line that extended far down the waste pipe into the next cupboard (install horizontal and away from the u-bend trap to eliminate a dripping noise and potential backing up of sink waste into the drain-line in the event of blockage). All parts supplied fitted my standard UK kitchen (15mm comp / 1/2" BSPP) but I did use some PTFE between the threads just to seal them as the thread form is NPT and my kitchen is BSP (thread angles are slightly different and therefore do not mate perfectly). I have had no leaks in the week I have had fitted.Taste/Testing:The taste is incredible. It tastes pure and clean. No tang or bitterness. It tastes purer than the purest bottled water I have tasted. I will now avoid drinking water that has not been through my RO system. Bottled water at a push! I have (glass) bottles stored in the fridge filled with my RO water. Bottled water is nice... but iSpring RO water is second to none. I agree with another review here that I fill my bottle with this water and take it everywhere I go.See the images for the testing. I believe that these images speak for themselves. Obviously, the RO water cannot be TDS free due to the remineralisation process but down to 47PPM from 435PPM is an incredible job and there is a clear difference in the ‘clean’ taste even between RO water and bottled water. This is evidence enough that the water is truly forced through the osmosis filter.Alkalinity of this water is slightly higher (TAP is 7.66pH, BOTTLED is 8.70pH *Sometimes artificially raised using Bicarbonate of soda, RCC7AK RO is 9.72pH). Yes, I did calibrate my pH meter prior to use! I am yet to perform some detailed research into the difference a higher pH water provides but brief research suggests that it is easier for the body to consume. I will take higher pH being better for the body at face value at this point for this review.Overview:I would suggest that this unit is installed in every home for the sake of reducing the number of chemicals that are consumed through water. At the very least, bottled water should be consumed. Avoid tap water! For the small cost (yes, the cost of this unit is relatively low) this unit is 100% worth purchasing. Fitting is easy, it comes with a nice outlet for the water, water tastes incredible, and the customer service is outstanding. Every home should be fitting one of these units. And whilst you are at it... consider stopping using fluoride containing products such as toothpaste and mouthwash. Use fluoride-free alternatives. I have personally noticed positive differences with regard to dental/mental health.BUY the iSpring RCC7AK! – I was not provided any incentive to leave this review. All opinions are from my experience of using this product!

I really love this. It’s pretty big so you need quite a lot of space under your sink. The filters are big but filtered water goes into a tank and the tank is big too!My man is pretty handy and was able to install this himself but there are a couple of things to be aware of. It comes with American fittings so you need to buy flexi hose to connect it to our sink. It also comes with its own tap so needs space to install this which inevitably involves some drilling in the sink or work surface. Installation isn’t necessarily easy and depends on having the right tools and correct parts for the job.The tap is quite small and the water comes out quite slowly. However, the water looks and tastes clean. I can’t drink regular tap water now as it smells funny.You never really know whether these things are working. I live in a hard water area. My new kettle had limescale in it within a week. Since using this filter there is not one single speck of limescale… that’s good enough for me!The filters need changing once a year and are pretty competitively priced. As well as taking things out the water, this also re-mineralises with the things you want to keep. I’m really pleased with this and the water definitely tastes better!

Love the filter so far! You can really taste the difference, because the water that comes out doesn't taste at all. Pure water available for you to drink, cook, or use it for skincare.The system requires a good 2 hours for the installation, but it's definitely worth. Notice that you will need to search for the YouTube video if you will install the system by yourself and you're not a plumber or expert in plumbing, and there are 2 videos. The one that you need is the video posted 3 years ago (which is the most recent and for this same product).

I've been through every cheap filter on the market. I've had a distiller after those which I absolutely loved! The water tasted amazing but my electric bill was eye watering. I did some more research as to an alternative for the distiller and found my way back to a reverse osmosis system. They kind of baffled me before now if I'm honest and I didn't understand how they worked so I bypassed for other options. I wish I'd just started with this. I've wasted thousands on electricity bills over the last few years with my distiller and it is a pain to clean and a chances of getting burned during cleaning process. This reverse osmosis system was easy enough to install (well took a few hours) and that's it, we pour straight from tap no chance of getting burned or having to clean it after every use - brilliant !! And the water tastes good. I often get sick with tap water and this passes the taste test 100% I've already sent the link for this to friends who distill water, urging them to change over too!Lots of pros to it:- water is clean. It tastes good. The price was good (I got it on a January offer). I like that it has a separate tap.The only con that might bother some is that it takes up most of one side under your sink. I have the space for it but some might not. But then if you're serious about clean water it's either the space gone there, or space in your fridge for a filter or space on your side for a distiller....so....Also if you're not handy around the house you might have to get someone in to install it. We did it ourselves but some may not be able to.(I'm not being paid for this review I genuinely think it's great after trying so many other options!)

OK so I've given this a 4* and not 5* because I think the kit could include a few T pieces for the fridge.That being said, this kit seems very solid with comprehensive instructions.My supplied tap had a small leak but made contact with iSpring and a few days later a replacement arrived.Would definitely recommend.
