Right out of the box, you can tell this product is well made. The instructions could not be any simpler to understand and the installation was a breeze. I watched a couple of YouTube videos prior to starting, which made it that much easier. The most difficult part was drilling the hole for the spigot through granite. I started using a carbide drill, but had to purchase a diamond drill bit from Amazon which cut through the granite with ease. Overall, the water flow from the spigot is perfect and the 5-gallon tank means you will not run out of water with normal use. The water quality is amazing and the water taste was noticeably different from our well water. I would highly recommend this system and the price is such a huge value.

I'd like to say that this is one of the best systems I've ever seen to have such easy to install parts. It is so well color coordinated. It was a bliss to put together. The resulting tds is still a bit high at 27 for me. Hence the discount on the stars

This was a great system to install as the instructions and video made it very clear. I had two minor leaks but it was not the system itself but my the tightening of water line connections. I did not want to over tighten but a had to tighten 1/4 turn and bingo. I got a 3 year supply of cartridges so I should be set until 2027. My TDS reading once installed was at 9. Anything from 0 - 50 is very good drinking water. Very good reading. I am not sure about these tablets mark S have anything to do with the system and I must find out how to purchase more if required. Other than that minor issue, I am more than pleased with this osmosis system. Great value, easy install, great drinking water reading. Happy wife, happy life, for now.

Fácil de entender. Fácil de ensamblar. Recomiendo lubricar las juntas con lubricante de silicona grado alimenticio antes de ensamblar. Ayuda enormemente y extiende la vida de los empaques. La instalación a la toma de agua es el paso crítico porque depende de la tubería. Desde ahí, todo muy sencillo. Claro. Excelente la válvula de autostop. Tener cuidado porque si le caen unas gotas de agua ya instalada, la almohadilla es muy sensible y se expande. La calidad del agua muy buen. El medidor (no incluido) marca 1ppm.

Very happy with the product, it’s my second one, I purchased the first one and I installed it in my house, but I sold the house and left the product there, so now I am in my new house ; and purchased it for the second time, very happy with it, very easy to install, the colour coded tubes make it easy for tubing, they give you 3 extra filters as a spare part. Now I am not worried about the quality of water I buy from the market, and I saw many videos that they cheat by filling tap water in bottles, even Costco water is not healthy for drinking.Buy it , it does worth the money you pay.

We actually have pretty decent tasting, clean water already. Absolutely no complaints on that one but some of the reports of what even very low-levels of some chemicals may be doing are enough to raise some concerns and this is decently priced so we decided to give it a go.Although installation was not too difficult, there were a few, fairly small issues that could have been smoother. Firstly, the instructions include no clearances or dimensions so the installer is left to measure and um-and-ah for themselves. We have a slightly awkward install as I decided to place it in the corner where there is some otherwise infrequently used space. There is a permanently installed shelf there. After a bit of backward-and-forwarding, I was able to ascertain that there was clearance for the tank and for changing the filters (with about 1/4" to spare). A mounting template would have been a very useful addition. Due to the confined space, I mounted one of the screws very slightly from where it needed to be and had to move it.The instructions are laid out like a brochure. Not terrible to work from but it means you have to hunt for the specifics sometimes. Other than the aforementioned dimensions and template, they're pretty complete though although it claimed a washer for the faucet that I didn't appear to have. It didn't seem to affect anything.You'll want to attach a fair amount of the pipes before you're crawling under your sink, especially if you have reduced access as I did. The top two filters are also probably best removed for the first part of the operation. They pop back in pretty easily.The faucet is a bit of a pain to install, especially with the small nut and that you can't attach the pipe before the faucet is installed (having a way to do that before was a godsend). I tried using the push-fit attachment first but that somehow seated wrong and was leaking. The plastic-olive alternative works fine though. A small, cheap angled wrench for tightening up the nut(s) would be a welcome addition to the kit. I did have a regular wrench but it wasn't ideal for the space.The short pipe to the leak-stop mechanism is just a bit too short. I had to mount the filters high because of the shelf and that means it doesn't quite reach the bottom. I bought some more pipe to give me that extra length but just a few more inches would have been nice.The water itself... To be honest, I can't taste much difference. It's good but, as mentioned, it tasted good anyway. I have noticed that flavored drinks seem to taste a bit better though. Maybe a hint less of a chlorine smell (though that wasn't really an issue anyway). But it's more about the health side of things anyway. It might be interesting to see the difference in TDS but I'm probably not going to bother.Oh, one other thing is that the shutoff exits to the right but my system is to the left. Not a big deal, just a little annoying. I couldn't see any way to switch it over.Edit: Having used for a few months, no complaints. There is a slight whine when running the faucet but no big deal. One thing that could have been included in the box would be replacement schedule labels. It's not hard to manage ourselves, of course but it would be a good way for the company to encourage filter replacements. An app might be an idea too for people who would use such a thing.

Out town water supply is very good, but they tend at times to overdo the chlorine, which my wife did not like. For years, we had a water cooler sitting in the kitchen and had bottled water delivered. This year I had the water provider start delivering three gallon jugs instead of the five gallon ones, a small concession to this eighty-seven year old body.The filter system arrived three days ago, two days ahead of schedule, and two days later we had our first drink of the filtered water. Installation was straight forward. If anything, the instructions are over-kill. (Don't hook up to the hot water, really?) Although the advertisement on Amazon provides the dimension in inches, I had really not appreciated the size of the unit and the tank. They are big. The layout I had in my mind had to be changed. The barbarian who installed the sewer lines did not help with the lay-out he came up with.My system (RO) faucet was supposed to come with a large and small rubber washer. The small one that was supposed to go between the faucet and the base plate was missing. I installed it without it and don't see this as a problem. I had some concern with having the leak-stop-valve installed on the cabinet floor. The idea is that it will work after the cabinet is flooded. Not ideal. I commandeered one of my wife's baking pans, and modified it to fit under the filter unit then secured the valve in this. All the connections, save the one to the tank, will now only leak into the pan. In the instructions there is a note that the system should only be installed in a location that has drainage. Really? In a normal kitchen? Never seen it.With a mind towards changing the filters when required, I left all the lines long enough so that the unit can be lifted off the tray and brought right out into the kitchen and placed in a tub. Unfortunately, the white tubing provided to connect the leak-stop-valve to the filter was far too short, I don't know why they were so skimpy with that one, but they provided enough extra red tubing to do the job.To make sure the tubing was seated correctly, I wrapped a bit of electrical tape 3/4 of an inch from the end as a guide. When it is right, the tape will be close to the connection.So far so good. No sign of any leak. The water passed the 'wife test'. After we have lugged the remaining jugs of bottled water up from the garage, and used them up, we will dispose of the cooler. Happy camper here.

We have a dug well and the water is potable, but salty. Amazingly it also hard??? I guess is happens. We have a pre sediment filter, uv, softener and carbon filer but the water was still too salty to drink. This RO system makes great tasting water, although i have not had it tested to measure the actual impurities. If i had 1 complaint, it would be the faucet. Its not the highest quality but seems to work fine. 5 stars for the price and bonus extra filters. Very pleased with the unit. Install was an hour and expect about a day before you can start actually using it. We are a family of 4. House water pressure is 40-60 psi.

I've had RO systems for the better part of 20+ years. Our household goes through a lot of fresh water daily, so having an RO system has paid for itself many times over. Even if you don't go through a ton of water for drinking, cooking, iced tea, etc...the convenience of not having to buy unlimited amounts of bottled water and/or filling water jugs at your local water store is definitely an added bonus. I've had 3, 4 & 5 stage RO units throughout the years and they've all produced great tasting water. My past 3 or 4 RO units (which are usually purchased when we move houses) have been Watts Premier models. They specialize is very fast & easy filter changes and they are definitely easy filter changes. However, you pay a little larger price for that convenience. Their 4-stage RO units run about $200 and the yearly filter changes run about $60. RO units also have 2 types of faucets: 1) faucets with an air-gap and 2) faucets without an air-gap. By definition: "Air gap faucets were designed to protect the RO system. In the event of clogging, a small amount of air, rather than dirty water, would go back into the RO system". The air gap will always make some noise when the tank is filling as air and water pass through the drain line and sound escapes from the little air gap hole. The Watts Premier RO systems have an air gap. If your system has an air gap, you cannot replace the RO faucet with a non-air gap faucet...you need to replace the faucets (if necessary) with the same kind. During my most recent search for an RO unit to install in a new home purchase, I came across this Express Water RO unit at an amazing price (which included a year of filter changes). I was a bit skeptical given the price, but the amount of solid reviews made it an appealing option. I made the purchase and had friend help with the install since I am a large framed man that does not easily fit under the sink area. After a month of use, I can say I am very happy with the taste, performance & overall experience with the RO. With that said, I found myself missing the benefits of the permeate pump that I had installed in my last house. If you just care about the RO review, then I am very pleased and give it 5 stars. If you want to know what a permeate pump is and WHY you should get one, read on.This is the permeate pump available on Amazon that I purchased and am reviewing below:https://www.amazon.com/gp/product/B005VPPRX4/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1Let me start by saying I will NEVER have another RO system without a permeate pump again. Permeate pumps use the wastewater that is expelled during the RO process to greatly increase water pressure at the RO faucet, minimize wastewater and fill the tank in less time. They can be installed on nearly all standard RO systems aftermarket so there’s no need to buy a bundled RO system that includes the permeate pump (since most of those cost a lot more than buying the units separately).I was introduced to permeate pumps about 4 years ago. I purchased a Watts Premier RO system from Costco (when they still sold Watts Premier) and had it installed by a plumber (since I needed a hole drilled in my granite countertop). I consider myself pretty handy and although plumbing in general isn’t rocket science, I’m a large framed man that hates trying to squeeze under sinks to do pretty much anything plumbing related. After the RO was installed, I was getting smaller (and broken) pieces of ice at my refrigerator since my RO was feeding my ice maker through a longer 1/4” line from the kitchen island to the refrigerator. This a drawback of a lot of RO systems which feed ice makers that aren't in very close proximity. After researching I came across a permeate pump (sold through Watts Premiere) and made the purchase. The included instructions were specific for the RO unit I had and it was an easy install since the RO was already up and running. Immediately, you will notice several things with the permeate pump. 1) Permeate pumps make some noise. They generally click or “thump” every few seconds. This happens because the wastewater from the RO builds up pressure inside the pump that is then used to push fresh (permeate) water into the storage tank. When the pressure builds and releases, you get clicking or thumping until your tank is full. 2) Your RO faucet pressure increases dramatically. As a result of the increased permeate water being forced into the storage tank, the tank pressure within the tank bladder increases and you end up with water pressure comparable to your regular faucet. The line pressure at the refrigerator & ice maker (assuming you have them all hooked together) is also the beneficiary of the increased pressure and you get full sized ice cubes again.So, why wouldn’t everybody want one of these? Well, I think most people have never heard of them. If you have, then the results speak for themselves. HOWEVER, these do make noise...especially if your RO faucet has an air gap (that little hole in the back of the faucet that inevitably leaks water out of it when the drain line gets blocked with something). With an air gap, permeate pumps get VERY NOISY. The pump action not only clicks (or thumps) under the sink, but the air gap sound created from the pump gets much louder as well. The air gap noise on my Watts Premier Pure Plus unit was so loud I actually debated on getting another permeate pump in our new house. I ended up buying a highly reviewed non-air gap RO system from Amazon and had it installed for a month in my new house. As usual, the water taste and purity was perfect and I am pleased that my ice cubes were normal sized (since the builder installed a larger RO line from my island to the fridge). I just realized how much I was missing the RO tank pressure (which equates to faster filling of water jugs & cooking pots). I went back to Amazon and found this permeate pump which said it was the newer model that makes less noise. The unit arrived in about a week (no 2-day prime shipping available for it). I watched a YouTube video for installing it on a basic 5-stage RO and had it all hooked up in about 20 mins. I’m once again in RO bliss. The water pressure in the faucet just makes me smile...no more waiting a minute to fill a normal glass with water (OK it’s not literally a minute but felt that way to me). The noise is considerably less from the pump itself. I ended up buying some u-shaped plastic clamps (Amazon search: TmallTech Big Simple Clip Clamp 2.5" Bracket Reverse Osmosis RO Membrane Housing (Pack of 3)) that hold the permeate pump to one of the RO filters so the pump is not directly mounted to the cabinet wall (like it was at my previous house). Also, since I don’t have an air gap on this RO faucet, I have no additional noise from the faucet. If my house is silent, you still hear the pump cycling the water, but it’s minimal and it’s only until the tank is full. After that, it doesn’t cycle back on until water has been used from the tank. All in all, I missed the permeate pump benefits and will never have another RO system without one. I will also make sure I don’t get an RO with an air-gap faucet either.Hopefully this review helps people.

Bought this to create base water for brewing, opted to go with the basic RO which was the right choice. Comes with 1 extra set of filters, which makes that picture in the product a little misleading but that's enough filters for what they say is at least 1-2 yrs (I'll be testing TDS and using taste as my indicator, not blindly following dates). They use standard canister sizes so any filters would work, but I'll probably buy the multi pack because its also reasonably priced.Package arrived quickly, and the packaging was definitely done well. Maybe a bit wasteful with all the different boxes. Kind of a pain to get rid of it all.Assembly was a no brainer, put it together with no tools, no issues, and not a single leak (I feel some of the people who have had problems on here maybe lack experience?). Flushed the primary filters for about 15-20 minutes to a drain before hooking up the RO and PAC in line. Can't comment on how long it took to fill the tank, but I will say watching the drain the ejection rate looks like it is quite efficient, definitely much much less than my old system I used for my fish tank.TDS tested at 5, tap water here is 140-160, and bottled RO here is about 6-7, so I would say it works perfect, I expected anything under 10. Its connected to my fridge water supply, my only complaint is that the flow rate is much lower than my line pressure, but its also pushing up one level (filters in the mech room in the basement), so its a minor inconvenience. Taste is really good, very happy with that. Definitely recommend this unit!

I purchased the 5 stage home drinking reverse system on March 1st, and it arrived at my north central Ohio home on March 6th. I was pleasantly surprised when I opened the box. The unit is a quality built unit, with a manifold that houses the 3 standard filters on the bottom, with the RO filter and final charcoal filter on the top, in the horizontal position. The unit was complete with fittings to connect it under the sink, and includes the sink faucet with a nice mounting washer that fit in an existing hole in my stainless steel sink. It even included the safety clips for all of the push to connect fittings that makes them nearly impossible to come apart if the clip is in place.I installed the system on Saturday, the 7th. If I were to mount this under the sink, as it was intended, I am sure that everything I would need would have been there, except maybe for a fitting to tie into the water line. The one supplied is for a different size line than the ones in my home. I installed the unit in the basement up in the floor joists. I hung the manifold by two screws into a floor joist, next to a beam, so if I ever finish the basement, I would not have too much hanging down. The tank was 11-1/2” diameter, and it would not lay above the beam as I had hoped, so I ripped down a 2X4 to 2-1/2” wide, and tied it onto the 9” floor joists with a couple of dry wall screws, and put a piece of plywood on it with some more drywall screws and laid the tank on the shelf, directly behind the manifold.I wanted this unit to supply water to my sink, my refrigerator, and my Keurig coffee pot. I tied into the water line, through an existing saddle valve that was used for water to the refrigerator. I ran the supply line, about 10’ to the RO unit, and fed it through a supplied valve. The plumbing was very easy and straight forward. I did add a permeate pump, which I also purchased from Amazon. It was the ERP1000-JG-S and it came with fittings, some tubing, and a mounting bracket which I attached to the manifold on the left side by drilling two holes. I probably would not have needed the pump as I have 70psi water pressure, but my water is from a rural water company, and is fairly expensive and I didn’t want to put too much down the drain so the permeate pump would waste much less as it relieve the backpressure the RO water puts out as it tries to fill the tank and uses the waste brine as the pumping power source.I stepped the ¼” output line to 3/8” and ran it through a “T” to branch over to the sink, and back to the refrigerator and coffee maker. Near that end, I stepped it back down to ¼” to go to those appliances. This allowed me to make a longer run with less pressure loss.I also purchased the HM Digital TDS-EZ Water Quality TDS Tester and it arrived before the RO system, so I tested the water and it was 172ppm Total dissolved solids. I took the tester to work, and compared it to a similar unit we had at work as we have a large, commercial RO unit there that produces up to 600 gallons a day. The low cost HM Digital read identical to the high end unit we had at work. On my first batch of RO water, I tested it and it was at 19ppm TDS, which is a great number considering, the first tank gets dumped as it had impurities in it from the coating on the RO membrane and the other filters. After two weeks, the water quality has settled in at about 15ppm TDS.The water from this unit tastes great, with absolutely no odor, and is of very high quality. I ran around for a day, testing every brand of bottled water I could get my hands on with the HM Digital TDS meter, and found that the water through the RO system is as good as, and better than most bottled water you buy. I doubt that you will find a better unit than this for twice the price. I looked at the big box stores, and most of the RO systems they sold used custom filters that they rip you off for. The filters in this unit can be purchased at a lot of different vendors, and the four extra filters they supply makes this an even better value. They do not supply an extra RO membrane, but that is usually rated to last up to 24 months so it won’t need to be replaced until after the extra filters have been exhausted. Plus, if you want a higher capacity unit, you can purchase a higher capacity RO membrane, which I may do when I wear this one out after a couple of years, but for right now, it supplies all the clean water I need.One last note, if you are looking for a Keurig coffee maker with a water supply, you may not find it. I added a Okeler Adjustable Mini Plastic Float Valve which I also purchased from Amazon to mine as I got tired of filling it everyday.
