RO System

I’ve been using this reverse osmosis water system for about five months now, and I can honestly say it’s one of the best upgrades I’ve made for my home. Even after months of use, my TDS reading is at 9 ppm and the water still tastes like bottled water. The difference in water taste is huge for me, it’s incredibly clean, crisp, and refreshing. Even guests have commented on how good it tastes. Five months in, the water still tastes just as pure as it did on day one, which really speaks to the system’s reliability. It’s made a noticeable difference not just for drinking water, but also for coffee, tea, and cooking—everything tastes better. Installation was straightforward, although I will say the filter housing can be hard to screw on, I had to use a hammer to knock the wrench to get it tight. Overall, this system has been well worth it for the peace of mind and the consistently great-tasting water. Highly recommend to anyone considering making the switch from a Brita!

The best health purchase we have made in a while!!! The product came fast it came with an extra set of filters for the three main stages of filtration. It came with fittings to install completely with a simple set up. I laid out the set up to decide if I needed anything extra to install under my sink. I have both a ice maker and a small hot water heater for instant hot water for herbal tea under the sink and I wanted both of them to get the filtered water as well... So I needed an extra 1/4 inch tee and a few feet of 1/4 poly which I went to the hardware store to buy... You can design it how you want and I also got a 1/4 inch shut off to put on my line that feeds my hot water heater, so I can turn it off and work on it if I ever need to and not have to turn off my filter water... Make your own plans and go to the hard ware store and get the advice from the workers there and just go for it and you will not be sorry, because this is a great purchase. I contacted the seller and got semi clear covers and they were awesome to work with, but clear is not recommended because it could introduce light into where the filters are and theoretically introduce light grown organisms... So it needs to be where NO light will get to the filters, if you choose this option and the cans are off clear and if I had to recommend one or the other, I would stick with the white as they are the best; but I wanted to mention it as this company is so good and responds to your needs so well and I felt obligated to let others know that they will take care of you if you need something... I was curious how the ice would be after we installed this system and as others had said ... the ice was almost clear, which was cool :)... I will add this as it might be something you do it your-selfers might want to think of doing... While I had everything removed from under the sink, I also got a small piece of lanolin and put it under the sink and brought it up on the sides a couple inches and calked in so that when any water does spill, when changing filters, or simple wear on valves / faucets (as it is inevitable over the years) it is no problem whatsoever and it looks nice and clean and was so cheep and simple to install... (note: I made it so if ever there is a leak on any of my many fittings, water will come out the front and onto my sink rug and I will notice it and not have any problems going under cabinet/down stairs... looks good too) Water quality when measured at the same time from the regular faucet and unfiltered using a TDS unit (total dissolved solids) purchased here on Amazon is at 254 ppm (parts per million) and after it has been filtered through this unit, it was at 17 ppm and a week later it dropped to 14 as it cleaned out I guess (if I just barely touch the water with the tip or reader it is below 10 and if I Put entire end into water it is at 14 (It might get a bit lower as it gets more water through it, and water; and obviously, minerals will differ from one location to the next... ).. Water tastes similar to distilled water as compared to our regular water... We could not be more happy to have this very inexpensive and quality system in our home and the extra security of having pure water is awesome!!! LOVE IT

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=1 Let 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.

Express Water System 5 Review Overall, a fairly decent system. My first unit lasted around 4 years before it started leaking—couldn’t fix it despite replacing both O-rings and tightening multiple times. Eventually gave up and bought a second unit. Later did a closer check on the old system and found a crack on the GAC stage—glad I didn’t waste more money trying to fix it, though it’s surprising it cracked under just moderate water pressure. For the price (especially with the included replacement filters), I think it’s reasonable to replace the whole unit every 3–4 years. Total cost of ownership feels fair.

I owned an iSpring 5-stage system for about 6 years. I liked it, but it eventually developed a micro-leak inside the cover, so it was time for a replacement. I decided to try the Express Water RO5DX, and honestly, I believe this system is superior to the iSpring in almost every way. The Good: -Value: It feels like an improved version of the iSpring but for over $100 less. -Installation: It came mostly assembled with color-coded plugs and even had Teflon tape pre-applied on many connections. The instructions are diagram-heavy and very easy to follow. It includes all the necessary tools. -The Leak Stop Valve: This is an incredible piece of engineering. It’s a mechanical valve (uses a compressed sponge that expands when wet) to shut off water if a leak is detected. After my experience with my old system leaking, this gives me total peace of mind. (iSpring had some battery powered detector that just made a noise.) This one actually stops the leak if it detects it by shutting off the value. I am so shocked about this. Peace of mind if something terrible happens and i'm not around. -Design: The filter housings are labeled, which will make future replacements a breeze. The connectors feel more solid than my old system. The "Okay": -The Faucet: It’s a little uglier than the one that came with my iSpring, but it works fine. -Drain Saddle: While nicer than the iSpring one, it was still a bit small for my drain pipe. Installation Tips for Buyers: -Drain Saddle Seal: To get a tight seal on my drain pipe, I used some sticky putty (blue tack) around the hole before tightening the saddle. It created a perfect seal. -Tank Pressure: Mine arrived at 4psi. I used an electric tire inflator to bring it up to the recommended 8psi. -Flush the Carbon: Before connecting everything fully, I used extra tubing to flush the pre-carbon filter into a bucket/shower to clear the black carbon dust. I did the same for the post-carbon filter so it wouldn't get into the tank. -Tubing: I cut the tubes shorter to reduce clutter under the sink—easy to do if you are familiar with these systems. Overall, replacement filters are reasonably priced and the water tastes amazing. I couldn't be happier with the switch. **This review is done just after install, I will update review if things change, Initially I am EXTREMELY impressed and happy with my purchase**

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.

Works as Advertised! Here in Calgary, the Lefties decided we needed fluoride in our water. I don’t like more fluoride as fluoride is a naturally occurring substance in River water. This takes care of fluoride and any other contaminants. We were using a zero pitcher for our drinking water. Water is as good or better than that and our zero water filters only lasted a month! Water tastes fantastic too! With system running water to our fridge we have 5 filters cleaning water after the osmosis filter. Installation was easy. Have been running for six months and just coming up on first filter change. Damn dog likes water so much she won’t drink anything else! Won’t be disappointed .

Muy buen purificador de Agua, el agua sabe muy rica además de que viene con un set de repuestos, lo unico es que compren la bomba de presión por que en México es muy baja la presión y no funciona agréguenle mínimo unos $2500 pesos mas de la bomba, yo la compré en home depot por rapidez me costó $3300 pero en amazón está mas barata, su instalación es muy sencilla. el instructivo está en inglés pero hay videos de Youtube, recuerden reutilizar el agua que sale de desperdicio, sale limpia, pueden instalar un bote de recolecta del agua o mandarla de nuevo al aljibe.
