iSpring T32M Pressurized Water Storage Tank with Ball Valve for Reverse Osmosis RO Systems, 4 Gallon, 1/4" Tank Valve Included, White

Update: As per my review below, I had some trouble installing due to instructions that were not really clear or suited to this particular product, which Ispring says is brand new. Since then they actually tracked me down and cared about what I had to say. According to them they are rewriting the instructions, not shipping with the funny dust caps, and considering additional parts to make the installation go smoother. I was impressed because in this day and age few companies actually seem to care about what their customers really think. I have come to the conclusion that this company does. And the filter system is now working fine, so don't hesitate to buy. I'm leaving my review below in case it takes a while to update the instructions. It might shave a few hours off someones install time. Changed to 5 stars. If you have any problems they will definitely help, and that is a really good thing. ================================================================ Just finished the installation. I'm a pretty handy monkey, but the installation took about 5 hours of my time (including 3 trips to the home improvement store and a some-what helpful phone call to ispring). First-off the manual is misleading and clearly written for another product or previous version of this product (or maybe a new-fangled sausage making machine). The parts of the manual that do apply to this product, like how to connect the little push-on connectors, suffer from an excess of brevity and lack of detail and conciseness. In an attempt to be helpful to future purchasers of this product, at least until ispring updates these kits and instructions, here's what I learned: First tip: the faucet included in my box does not require a 1/2 inch hole, as the instructions state, but a one inch hole. Actually one inch is too tight, make sure you have a 1 1/8 inch hole saw attachment for your drill, and make it a good bi-metal one if you need to cut through a stainless steel sink. Home depot sells rigid brand bits that suit this purpose. It will run you about $15 unless you already have a rigid brand bit shaft (or equivalent). Second tip: the faucet that came with my filter has three colored plastic hoses already permanently attached. Red, white and blue (I dig the patriotism). Unfortunately which gets attached where is not mentioned anywhere in the manual. In the manual it says to screw the water hose to the bottom of the faucet. Clearly referring to a different type of faucet. Also if the three hoses were just a little longer you would probably not need to bother adding extension hose (an extra leak risk). More on extension hoses later. The colors are mentioned in the Amazon description, way at the bottom, but it bears repeating. "Connect the BLUE tubing of 3-color tubings on the faucet to cold water line, RED to the 1st stage on the right, WHITE to the 3rd stage on the left." Note: This is #ssbackward if you are from an English speaking country ... just saying. Third tip: The filter box itself has funny little horn or funnel shaped things on the ends of the inlet (left) and output (right) angle connectors. These are not mentioned at all in the manual. You can not push the hoses on with these in place (you can try as I did ... if you get excited by frustration) because these are some weird sort of dust plugs. You must pull up with your fingernail on the very outer ring of the connector (pushing it on a spring ever so slightly towards the more bulbous part) then with other hand pull the horn thing out. You can discard these, or I found they make nice hats for very small garden gnomes. Basically you can connect the red and white hoses now by pushing them with force into the connector until they snap. Pull back a little to make sure it is connected. If you need to cut extension hose cut it straight, and use the supplied double-sided connectors. I recommend you push the little blue horseshoe shaped clips (supplied) between that outer part of the connector and the more bulbous part. These (I think?) are to make sure the connectors can't shoot apart from water pressure. No mention in manual about these. You can leave them off, as I did at first, if the under side of your sink needs a good spraying out. Fourth tip: In order to connect the blue hose to the cold water line you need to first install some parts. My sink had a 3/8 inch stainless steel hose with female compression fitting attached to a male 3/8 compression fitting shutoff valve coming out of the wall. Pretty typical I would assume. The kit comes with a 1/2 inch plumbing style thread, male to female connector, with a hole to thread the valve the blue hose goes onto, in the middle. A way to tap into your cold water line, would be eazy peezy if it was threaded for 3/8 compression fittings, but it's half inch and has coarser plumbing style threads. So off to the Home Depot you go. Don't forget another roll of Teflon tape to add to your Teflon tape collection while you are there. Actually the folks at the Home Depot weren't that helpful (surprised?), but the small local hardware store in my old town was. You will need, as it turns out (if your sink is like mine) a 1/2 inch plumbing style male to 3/8 inch compression male adapter to connect your current hose leading to your cold faucet to this new part (btw thread the little supplied valve the kit came with into this part with a little teflon tape first so you can get it good and tight before you are lying on your back under the sink). Then on the other end you will need another short stainless hose (only way I can find to do this with available parts ... why it took three trips) 1/2 inch plumbing female, which attaches to other end of this new part, 3/8 compression female which connects to the part your faucet hose used to be connected to. These parts should run less than $15. Tip five : To connect the blue hose to the metal valve from the previous section you need to put it against the nipple, screw off the nut collar and slide it down the hose temporarily, then push it on the nipple all the way, and man it's a tight little bugger (I sprayed the nipple with a little Pam cooking spray, hey it was in the kitchen), then put that nut collar back on and tighten it down real tight with a half inch wrench. Why these filters don't come with a 3/8 inch compression fittings on each side of the filter box, so you can just screw your standard hoses on that you can get from any hardware store, is beyond me. There must be a reason. Maybe these filters are designed by the same folks who design those charming "blister packs" that you need a chainsaw to open? When I tested the water it was cloudy and tasted a little funny, it got better after I ran the tap for a while. Now it tastes pretty darn good. Even my cat likes it. Hopefully it will not develop leaks.

I am a General Contractor/Home builder. We originally had a RO system that provided us with excellent tasting water, but took up most of the under-cabinet and had to be sanitized with bleach at each filter change.. We don't have hard water and our tap water is drinkable but we wanted it cleaner, and the RO had intermittent leak problems. Could I find a system that would relieve us of the clutter , the maintenance, the water leaks under the cabinet, and still get great water? I decided to give the CU-A4 a shot. SO, Here goes what I didn't like, and then what I liked: CONS: 1. The directions do NOT adequately describe how to make the water connections. To someone who has installed with these type connections it is an obvious "no-brainer", but to the rest of us......... Parts of the directions appeared to be for a different unit, and especially the section on installing the faucet, which was obviously from their RO system and was not anywhere close to describing the faucet enclosed. The faucet enclosed is an "air gap" style which requires a hole in your sink deck or in your counter of 1 1/8" minimum. The threaded pipe that will go through this opening is 1" in diameter. If your existing hole is anywhere from 1 1/2" to 1 1/8" the provided washer will work fine. 2. While there was plenty of 1/4" tubing to do the installation, There are 3 colors of tube, red, white and blue. They provided plenty of blue and white, but not red, therefore I used white and labeled it red to make the job a clean install. 3. There is no discussion in the manual of run-in time after completing the install. The water was barely drinkable after letting it free-flow for approximately 10 minutes as suggested in the notes . After flushing the system with approximately 15 more gallons the water was crystal clear and the flavor has become progressively better and better and has stabilized. PROS: 1. The system IS actually easy to install when you have familiarized yourself with everything they have sent and how it will work with your existing plumbing and sink. AND you have purchased anything you might need so the system will integrate seamlessly. 2. The snap-fit connections work great and do not leak a drop. 3. Twist on replacement filters. How could it get any simpler??? 4. Takes up minimal space. 5. The faucet is all metal construction. 6. After initial flushing and after the first week of use (approx. 1 Gal per day)t the water tastes GREAT. As good or better than any of the bottled waters we have tested against. 7. Every time I have called them (of course during business hours...duh...) they have been very responsive. So, customer service gets a nod. CONCLUSION: Well worth the money, Simple design and install Great tasting water NOTES: 1.There is a review about salt taste. If you have softened water, then you may want to contact your service company regarding what is best to work with your existing system. At the very least do an internet search on how softeners and filters can work together before purchasing this system. 2. There are reviews that mention a 1/2" 3-way valve and having to buy adapter fittings. My system came with a 3/8 to 3/8" 3-way valve (which worked perfectly), so it seems iSpring has changed it to the more typical size. 3. One reviewer gave 3 stars because this system does not reduce TDS and it cost them 10% restocking to return it. TDS is reduced by RO systems, This is NOT a RO system. iSpring does not claim reduced TDS. If you need reduced TDS...iSpring has a very highly rated RO system ( http://www.amazon.com/iSpring-RCC7-Reverse-featuring-See-through/dp/B003XELTTG/ref=cm_cr_pr_product_sims?ie=UTF8 ) for about $200.00. 4. Most every review says the directions suck. I can attest to that. They do! Layout everything from the box, familiarize yourself with it, identify any problems with your existing plumbing. Take the 3-way valve with you to your local home improvement store and buy whatever you need. 5. Make certain you have the correct tools to accomplish the install. 6. For a water tight connection fit, remove the blue "horseshoe" clips and FIRMLY push the 1/4" tubing approximately 5/16" in to the couplers until you feel it "bottom out", check the assembly by firmly pulling on the 1/4" tubing. Replace the blue clip. 7. I made all of my tubing the same length and long enough for me to remove the filter manifold a couple feet from the cabinet to facilitate changing the filters when that time comes. The tubing is coiled and taped up (love that blue tape), and will be easy to undo and stretch out. 8. I purchased an extra set of filters ahead of time, and store them right next to the unit. 9. Instead of changing my filters by use of a calendar (such as recommended by the manufacturer, every 6 months), I will change them based on usage. Since we only use it for drinking and cooking, we likely will never hit a max avg of 3gals per day. Most filter manufacturers claim 6mos. is relatively equal to 1200 Gals. Therefore 3 gals x 365 days = 1095 gals. (1095 is approx 90% of 1200 filter life). That is when I will change mine, at about 1 year. You also can adjust your schedule based on this formula. If you use 6 1/2 gals per day, you will hit the 1200 threshold at about 6 months. Were you to use 10 gals per day you would want to replace the filters after 4 months. AND so on. If you don't have a basin wrench, get one from your tool store, (see images) Make your life easier.

I've just replaced my filters after using the iSpring CU-A4 for 8 months, and I am happy with my selection. The options online are seemingly endless. I had been using a Zerowater pitcher & dispenser for 1 year before I decided to invest in this. I rent a unit in a 4-plex & my wonderful landlord/owner who also lives in the building paid to have it installed. I was aware that I'd be losing functionality from the Zerowater in that this system does not remove TDS. I read up on this as I tend to do, & ultimately I decided that I could live with this to keep the minerals rather than a more expensive, RO-type system that wastes water. I figured if the water didn't taste good I'd return it but it turned out that wasn't a problem. I live in California where drinking water is highly contaminated, & truthfully I would much prefer the best system available. But for today, as a renter with higher priorities governing my spending, this suits me fine. A few final notes: the iSpring vendor videos on YouTube contain incorrect info for how to remove & replace filters. They confuse clockwise & counterclockwise which is obvious as you watch it. Follow the hand action, not the audio description. I posted a comment on one video & saw another person had done so on another. I also mentioned it to the customer service guy who answered the phone when I called. That's my final & most appreciated piece: I called the phone number in the user manual & a person answered the phone. He was kind & helpful -- it was one of those situations where as soon as I had the rep on the phone I no longer needed much assistance. When putting a new filter in you must give it some pressure to get it up in there before screwing it in fully. I had read they gave good service & it is true. That was one of my purchase considerations actually, that the company is U.S.-based. I very much prefer to spend my money locally whenever possible, & one day when I own my own home I will certainly get a California-designed & produced system. For now Georgia has got me covered.

Install was a bit tricky, it took two hours, mostly figuring out how to do it, not the work itself. Once we figured it out, it took hands down 15 min! We were lucky and our cold water was already separated into two since I was putting the filter in the place where I had hot water faucet. Water tastes so much better than the tap - you can really taste the difference! (Totally worth the trouble of the install! :) Arrived promptly, packaged securely in the box, but as other people claimed the instructions are a bit unclear for a not so handy monkey as me when it comes to plumbing. I think it might be too technical and sometimes vague. Since I am still somewhat handy, I could deduct from the images in the instructions that somehow one tiny tube stopper part was missing from the package. Well, what is a gall to do? I contacted the company's sell department though their website (123filter), and did receive a prompt response the next day. The whole issue of missing little fitting got promptly resolved free of charge, and even got a USPS tracking provided! Now, if that is not exceptional customer service - I don't know what is! The product itself feels sturdy; nothing feels cheap about this system. I must say that I love the faucet included! Oh! It is beautiful! Some of these faucets for these type of undersink systems are sold by other companies for 80 bucks, and it looks nowhere near what this faucet looks like! This looks like Neiman Marcus compared to Macy/ Target! The price for this system is fair - I don't think anyone is fleecing you with this product on quantity or quality, and you are not fleecing anyone either. What is a great deal are the replacement filters for a year go for about 80-90 bucks, which I think is also really good compared to other systems. I hardly use my GE fridge water filter and basically pay around that much for that filter for a year. AND if you have some issue with installation (one-time time investment) - contact iSpring - they got your back! :) I picked this filter on the day I decided that my new condo needed a undersink filtration filter. I already knew quite a lot about filters so I was not a novice in that regard. I knew what a good filtration system should filter and cost. If you are looking for a system right now, please make sure you look at good quality filters based on what is actually being filtered (filter type), original cost, and then also take into account filter replacement cost. I bought this filter system based on these criteria. Choosing a right filtration system is quite a pain, especially for under the sink products. It can takes a good month of research, comparison of products, and then finally price hunting. In the process one learns enough about water germs and contaminates to start believing that nothing short of atomically decomposing the water will purify it enough! I went though this before with another system, and didn't want to obsess about percentages of stuff that gets filtered that I did not even know existed prior to the clean water quest I now realize choosing a water filtration system really is! Brita was one of my first water filtration system that I had attached to my faucet after I had DC water authorities test my DC water in my fancy Dupont Circe apartment. I learned that my cold water had enough chlorine in it as recommend for a pool. That was ten years ago. Since I came to DC from Sweden, I must confess that I was at the time absolutely ignorant of the fact that faucet water could be harmful. So I started with Brita carbon filters, which followed other over the sink and under the sink water filters. Since then, I have solid quality filters everywhere, and I don't live in DC anymore! If you think chlorine is no big deal - try drinking pool water for three years and see how your insides feel. SIDENOTE: There are quite a few parts in the package; I do think it would be helpful if the company included pictures of all parts that should be in the package and how they fit together because most of them I wouldn't even know what to call. A youtube video as for the osmosis product did help a bit, and I think if there would be one for this product as well, since not all clean-water enthusiast are osmosis converts, that would resolve the whole installation issue completely!

Got the 4 stage filter system (no ro filter). The instructions included are horrible and i basically figured out on my own how to install it. It comes with ro system connectors which cause confusion. Only use the white and blue water lines and the water valve that connects cold to spigot. Even the mounting bracket doesnt work so ill figure out later how to mount it so its secure. Water tastes great

I bought this T20M tank back in 2021, almost exactly three years ago to the day that this review is being posted. The tank is very well made and works flawlessly, but honestly I wasn't happy with the 3/8" shutoff setup (it was plastic and looked fragile and frankly a bit sketchy). However, I needed a pressure container ASAP and I didn't want to mess around with finding separate fittings to make the shutoff burlier. I reasoned that since the tank lives in an out of the way location, there was zero chance of it getting kicked or bumped. So I installed it and didn't give it a second thought. Fast forward three years. Five days ago I needed to modify some stuff on my RO setup. First step was to shut off the pressure tank… and when I do that, I notice that the shutoff is "loose". Hmm that seems odd. So I go to "tighten" it and it just pops off in my hand followed by pressurized water spraying all over me. I literally kneel there in shock for what seems like a century before I come to my senses and go full-on Hulk mode, pick the tank up, walk it to the laundry sink, and let it drain out. I stood there kinda laughing at the absurdity of the situation and was like "okay now I've got something new to do with my day" lol. So I re-plumbed the RO to remove the pressure vessel and contacted iSpring to see if they had a metal replacement fitting or could tell me the specs for something aftermarket. I was upfront that I was way out of warranty. I got a reply a day or two later from Nick asking for a screenshot of the receipt so we could move forward with warranty support. So I sent that, and with zero, and I mean ZERO, nonsense he got back to me the next morning and said that iSpring no longer carries replacement cone adapters for that model because they redesigned the tank awhile back (he didn't say why, but I'm going to assume that they needed to address the weaknesses I mentioned above) and that he would be shipping me a new replacement T20M (the new updated version) today even though I was out of warranty. I'm not going to go on some rant about the "shareholders first, customers last" mentality of most corporations (oops guess I just did), but this isn't some cheesy $1 cast plastic piece that's basically free to ship we're talking about here. This tank is big and heavy and costs real money to make and ship. Look, problems happen. And when a failure occurs with water involved, people get wet. But the fact that iSpring not only took the hit and redesigned the tank BUT THEN stood behind their name instead of hiding behind an expired warranty like most companies would, says EVERYTHING I need to know about them and their products. Nick, man, I want to thank you personally for going way beyond my expectations and totally brightening my day. I reached out asking for specs on a fitting so I could fix the tank myself, and instead I've got a redesigned tank shipping out today to replace the old one. Wow.

Very easy to install and it's an easy replacement for the tank that wore out. Once installed, water pressure is very high, and we now have a strong stream running from the faucet. Also went through the easy process to register the tank for the warranty. No issues and I was guided through the process by a representative named Robert. iSpring products are great and I highly recommend them.

Perfect amount! I have 6 people in my house and needed far more RO water. This thing is built like a Sherman tank. After the initial flushing, the water tastes pristine. Can't hear any drips or water pumping through it as I initially thought I would. It was easy peasy to install. Only had one tiny hiccup and it was my oversight. This tank needs a 3/8ths tubing a union connector between my RO system and this tank. Nick from iSpring immediately sent out the connector. This patient dude has been a great help with every question I had. Can't ask for a better customer rep. Product 5/5 stars Company 5/5 stars Customer Service 6/5 stars Give this man a RAISE!

Die Materialien wirken hochwertig und die Tatsache, dass er lebensmittelecht ist, gibt ein sicheres Gefühl bei der Trinkwasserlagerung. Anschluss: Der standardmäßige 1/4"-Anschluss macht die Integration in bestehende Systeme kinderleicht und hält absolut dicht. Fazit: Ein grundsolider Wassertank, der genau das hält, was er verspricht. Für Paare oder kleine WGs die perfekte Ergänzung zur Osmoseanlage. Klare Empfehlung!

My Experience with the iSpring CU-A4 Under Sink Water Filter I recently installed the iSpring CU-A4 under sink water filter, and I'm genuinely impressed. As someone who's always been a bit skeptical about the true efficacy of home water filtration systems, this unit has completely changed my perspective. First off, the installation was surprisingly straightforward. I'm no plumbing expert, but the clear instructions and well-organized components made the process relatively painless. Within an hour or so, I had fresh, filtered water flowing from my dedicated faucet. And what a difference it makes! The most noticeable improvement is in the taste and smell of the water. Our tap water, while generally safe, often had a slight chlorine odor and a somewhat metallic aftertaste. With the iSpring CU-A4, that's completely gone. The water is crisp, clean, and incredibly refreshing. It's truly a pleasure to drink, and I find myself reaching for water more often throughout the day. Even my coffee and tea taste noticeably better. I also appreciate the compact design of the unit. It fits neatly under my sink without taking up an excessive amount of valuable cabinet space, which is a huge plus in smaller kitchens. The dedicated faucet is sleek and unobtrusive, blending well with my existing fixtures. While I can't scientifically measure the contaminant reduction, the peace of mind knowing that my family is drinking water filtered through a reputable system is invaluable. The four-stage filtration process, including activated carbon and ultrafiltration, gives me confidence that we're significantly reducing chlorine, sediment, and other common impurities. In conclusion, the iSpring CU-A4 under sink water filter is an excellent investment for anyone looking to improve the quality of their drinking water. It's easy to install, produces great-tasting water, and offers genuine peace of mind. Highly recommended!

I waited a while to write this review as I wanted to see how this held up for a month. I can say this has worked perfectly, looks classy (not cheap), and the water has since a nice clean taste. I should have put this in years ago however I was always concerned that it would be too hard to do, or would leak or just from not knowing enough how these work. The install was literally under 20 minutes, so straight forward and the components, hoses etc are high quality. The hardest part was drilling a hole in the stainless steel sink, however I did not care much as the sink is old and we are renovating the kitchen fairly soon. Connecting the hoses was literally a snap, the unit fits under the sink no problem, and I made sure to leave the hoses longer so I can pull the unit out easily to change the filters. The faucet itself looks high end and the lever has a nice weighted feel to it, not cheap moving, more of a smooth range of motion. The only thing I wish was a little more solid was when I turn the faucet from side to side, say filling up the dog bowl on the counter, it is kind of flimsy, I wish this had the same feel as the water lever did. When I hooked everything up I had to let it run for a good 30 minutes to clear the filter sediment out, and for the first couple days when first used in the morning, there would be some sandy sediment. That was gone by the third day and crystal clear since then. I want to get the water tested and compare to this to see what is really filtered, that is my only question, you are taking the companies name that the filters work, and this is why you need to review and do some research. So far very happy and would buy again no problem!

Super easy installation! Very tasty water! Took away the tap water smell, and it does make a big difference although Amsterdam has one of the best tap water in the world! Quality product

I use this product to filter water for our production process as well as for drinking. I did need some hoses the larger tank did not come with so I called up Richard and he was able to help me out with some complementary hoses. I was up and running within a week!!
