Description
The iSpring RCS5T is a high capacity tankless reverse osmosis purification system. The RCS5T's high-efficient RO membrane produces RO water at a rate of 500 gallons per day while delivering a top-of-the-line 1.5:1 pure to drain ratio. The system removes chlorine, hardness, heavy metals, toxins, and a long list of other water impurities. The on demand output ability makes the RCS5T a great choice for large families or light commercial use in small restaurants, beauty salons, offices, coffee Shops, or any small business. Why iSpring? Located in Alpharetta, Georgia for over a decade, iSpring Water Systems LLC is a family owned company specializing in reverse osmosis water filtration systems. Our products include residential and commercial Reverse Osmosis (RO) systems, whole house water systems, ultra-filtration systems, shower, faucet, and counter top filters, filter cartridges and housings, RO coolers, and kitchen faucets and fittings. Our aim is to make high quality drinking water accessible for all households. With affordable pricing, solid quality, prompt delivery, and top notch customer service, we hope to assist in bringing you great water for years to come. Incoming Water Pressure: 40 PSI - 70 PSI Operating water temperature range: 40 – 100 °F Maximum TDS: 750 ppm Membrane Filter Life: 2-3 years at 3 Gallons/day or 2600 Gallons Note: All flow rates stated on our reverse osmosis systems and membranes are assuming a water temperature of 77°F. Water temperature changes will affect the flow rate. For every degree F the temperature lowers, about 3% of product flow is lost. For every degree F the temperature increases, about 3% product flow rate is gained. This occurs because water with a higher temperature has a lower viscosity and higher diffusion rate, which makes it easier for the water to permeate the RO membrane. Lower feed water temperatures during the winter season will result in a decrease in flow rate.

Set name: 300 GPD RO Tankless
We purchased the iSpring RCB3P Reverse Osmosis RO Water Filtration System, 300 GPD system in 2017. Initially there were damaged parts from shipping but the parts were promptly replaced (Nick from customer service is awesome). Our water was high in sodium and this system reduced the TDS from 450 to under 30. Prior to this system I was buying filtered water in 3 and 5 gallon bottles which was running me over $300 a year so this system has paid for itself multiple times. The system has worked flawlessly since 2017. We couldn't be happier with this unit. The frame of the unit is quite hefty and the motor, pressure gauge, and other electronic items appear to be installed well. I will update my review after I am able to test the unit. This unit cost over $500.00 so the initial issues are very disappointing especially since I have no idea how long it will take to get the broken part. 1/16/18 Update I sent iSpring an email via their Contact Us option from their website late at night after posting the above review.. I received an email from one of their representatives (James) the following day. He has been working with me to resolve the broken Inline Carbon Filter connections. He first had to verify my purchase. He is in the process of shipping me the replacement part now. So at this point iSpring customer service has been very responsive implying that they are concerned about the quality of their products and customer satisfaction. I will provide more feedback once I am able to test the unit. 1/21/18 I received the replacement Inline Carbon Filter on Friday 1/19/18. I was disappointed in that the replacement filter was a 1500 gal rated filter and the original filter was a 3000 gal rated filter. I'm upgrading this to 4 stars, if I hadn't had to deal with the connector issues and if I had known that I needed to do all the reducing and expanding of tube connections I would have given this a 5 star. The following information may help prevent some frustration. I believe that ISpring has some quality control issues since the iSpring RCB3P GPD Commercial Grade Reverse Osmosis Water Filter System w/Booster Pump and Oversized Pre RO Filters unit was damaged upon arrival and the iSpring 20 gal storage tank I purchased was also damaged upon arrival. The damage did not alter the functionality of the units they just caused some frustrations. During the test phase of the RO system I found another connector that had been broken during shipping. I didn't find the second broken connector until about 8:30 PM when I opened the water valve to the RO unit. Very inconvienent running to a parts store when they are all closing. I'm not sure why but the design of this RO unit (RCB3P) has an input of 3/8" OD tubing but the tube size is reduced to 1/4" OD tubing through the membrane cartridges and carbon filter. The output lines to the faucet and storage tank is 1/4" OD. The input to the iSpring 20 gal storage tank is 3/8" OD. I wasn't able to find connectors that reduce from 3/8" OD to 1/4" OD and visa versa so I had to spend a lot of time at hardware stores to find parts to do the trick. This is very frustrating and inconvenient for the customer. I will say that once all the issues were fixed the unit appears to be working well. My TDS reading before the unit was 435 and the TDS reading from the RO faucet is 26. I did run the unit for some time before taking the RO TDS reading since I wanted to flush out all the lines. In addition, the storage tank recommends that the tank be flushed after the first filling. Be sure to run the faucet and tank lines into a bucket or drain before connecting them to the house RO line and tank, this flushes out the lines all the carbon from the carbon filter. On the positive side: I installed a sharkbite pressure guage and a sharkbite shutoff valve just before the reduction from my house 1/2" copper line to the 3/8" OD tubing line. My pressure is slightly over 50 psi going into the unit. Our water pressure from an outside faucet typically fills at 5-6 gal per minute. The RO unit produced about a gal of RO water a minute with about a gal of waste water (to get this information I placed the drain hose in a 5 gal bucket and the RO faucet hose in another 5 gal bucket and timed the test). I'm not sure how this unit works without the booster pump but I highly recommend getting the unit with the pump since all the wiring and other electronics are already installed. Don't be alarmed if the pump appears to run for a long time. Once I started filling the tank It took about two hours for the tank to fill and the unit to pressurize enough to turn off the pump (the gauge on the RO unit read about 1 when the unit turned off). When the unit turns off the water coming out of the waste water line will also stop. Our RO water has no smell or taste so I'm not sure why some of the other reviews had those complaints, maybe they didn't flush the lines and tank and some of the flux or other plumbing chemicals got into their tank and now it's hard to get it out. As I did, I suggest placing both RO output water lines (line to the faucet and line to the tank) into a bucket or drain before connecting the lines to the faucet and tank, this will help remove anything in the lines and avoid contaminating your tank. I ran my unit in this configuration for about 20-30 minutes. It's been one day and now that the unit is working my frustration is quickly diminishing. I'll keep my fingers crossed that the design of the unit is a good design. Good Luck.

Set name: 500 GPD RO Tankless
Please see update below. We live in the Dominican Republic where even the city water is not so good so we had a whole house (+2 apts.) and animals using a filter and UV system for over 15 years. We have not had any city water for over 18 months now and in severe drought. We also have rain water systems to collect but with no rain, no water. Water trucks have over tripled their costs and the water that they deliver is from one of the most polluted rivers around. You DON'T want to know what we found when we cleaned it. We finally put in a well and hit water at 30 feet. We are on the Ocean so expected some salt but hit good water above sea level. The aquifer is mainly in petrified coral so very high in calcium. Everyone here has 3rd world septic systems so that also added to concern. But the water was OK for the lawns (aka extra pasture), gardens and horses. Word got around about my well and in 2 months, at least 20 wells drilled within 1/4 mile. The well water became unusable for anything as many went too deep and let the sea water inter as the fresher water was sucked up. We also noticed a very bad algae/bacteria problem in our pools and 2 cisterns. After much research and questions to Helen @ iSpring, we bought this unit. (THANK YOU HELEN!) We concentrated on what we had and what we needed to accomplish. Electric is also very dirty here so we are 90% solar with a good inverter and battery systems. Importing anything is expensive to ship and the custom taxes are outrageous. We needed to get this right the first time. Not worth shipping it back. Since most of our water systems are in a dedicated room, it was fairly easy to get up and running in a few hours with no real expertise needed. Advanced planning may be very important. 1. A couple of changes so that the well is dedicated to this RO system. 2. Well water goes through a de-scalar. (we already had so we just moved it.) 3. to an old sand filter that we cleaned up. 4. to a UV sanitizer that we already had. (I didn't want the bacteria and algae getting into the rest of the system. Though the RO will handle some/much/?? it may not be able to kill and separate all.) 5. 30 gallon pressure tank equipped with gauge, well pump on/off pressure switch, tank drain and connection to the RO. 6. Followed or figured out the RO system and hung it on the wall. (instructions are very poor so it took awhile) 7. New elec. serge protector mounted. Shelf for filters. 8. The RO fresh water line goes directly into our non-pressurized cistern. No other pump needed. 9. Waste water run into PVC drip pipes into the gardens. No other pump needed. 10. Prior to the unit arriving, we transferred around 7,500 gallons from this cistern into our second one to go in and scrub/sanitize it. Lot's of algae (and other stuff that you don't want to know about.). 11. Turn on well pump, fix a couple of leaks and open valve to RO and plugged it in. 12. Being that our cistern my have other contaminants leach in or I need trucked water added, that independent system also has it's own filters and UV. Observations: 1. Our 1 hp well pump will only give us around 65 psi while the best production would be at 75psi. (or higher?) I set my well pump controller at 42/62. 2. At that pump settings, I was getting 540 gallons per day. 3. Though I have not had the water tested yet, It is clear, no smell and tastes great. 4. The motor is very quite. 5. I have had NO issues in the week that I have had it running; 24 hours every day. 6. Electric usage is not a problem with our systems. 7. Waste water is doing great with my plants and even that is a lot cleaner. 8. Filters are available and good prices. I have read the Q&As and comments and thank those that have posted and most I agree with. Again to Helen.... THANKS for your support @ iSpring. After just a few days, we are very satisfied with this unit. We will give it a couple more weeks but I've already picked a spot for a second unit to be mounted right next to this one. (the name that appears as the author is my wife... lol) 9/22/15 UPDATE: Our 1st unit has worked at just about full production running 24/7 since we put it in. We just installed 2 more and up in running within a couple of hours of getting them and had everything planned so it was real easy for us being that we had worked through the instructions that are just very poorly done. Most of the info that the distributor states is OK BUT, let's take a look. I'm NOT going point out the differences between the distributors statements vs the instructions. My observations are my own. 1. This is a 110 volt unit and NOT a 220 V as the manual says. The manual states that it MUST be grounded but the unit comes with a 2 prong 110 V plug. The unit has a down-step from AC to 36 V DC that feeds the booster pump that helps the system but not by much. 2. The manual uses all sorts of different measurements and is not consistent. A. Water pressure in the manual is in MPa. Gauge is in PSI. Different figures for "operating pressure" and "suitable water pressure".? I converted and figured that the best PSI is between 72.5 and 101.5 in order to get close to the 500 gpd. I does work below that but output is going to be lower. B. Most homes have water pressure at around 45 PSI for city water. Well systems can be adjusted, like I did, but be very careful that you don't start blowing up your plumbing if you boost too high. Our new 1.5 hp well pump is dedicated to and directly to other filters/UV and our RO system and the first unit did not leak when pressure was at 120 PSI for a couple of weeks. We did have to repair other leaks. With the 3 units running we average 90 PSI for each unit with the gauge a little higher before the units. (some fluctuations due to our dirty power that effects the well pump.) C. The manual states that this unit is for less the 1000 PPM and does not include nor address biological problems. We have pre-filters and UV since our well water is closer to 2000 PPM and we know that we have all sorts of bacteria and stuff in the well water. Our processed water is around 57 PPM that goes into our water cistern. That water is treated AGAIN with filters and another UV since our cistern most likely has outside infiltration via leaching. D. DUCK... INCOMING? Consumables/filter replacement. (This is gonna hurt.) You will see filter packages that will last you a year. True IF you follow the manual and use their water usage rates. D1. average family of 3 uses 10L per day. (Drinking water only?) That's 3.3 L per day per person. That's less then a gallon per day per person. D2. According to other sources; the low average is 80 gallons per person per day that equals 303 L per day per person. This includes drinking water, cooking, bathing and toilet. D3. Using the RO unit 24/7 the filters, without pre-filters, will need to be replaced every 3 to 5 days. Now the manual starts using "Tons" but I don't know if these are US or Metric tons. Let's use US. D3a: 1st and 2nd filter is good for 7.5 tons of water. = 2,018 gallons. @ 500 gpd need to change these filers every 4 days. (Without pre-filters. We have an older flushable filter that we back flush twice a week and a larger filter that we change every 2 months so we replace the 1st RO filter once a month.) Monitoring the well water incoming gauge and comparing gauges on the RO units is very helpful to determine when filters might need changing. D3b: Filters 3 and 4, every 3 to 5 days. D3c: RO membrane is an unknown but it stated that it is good for 2 to 3 years. ??? That brings us to... E. "Flushing" the RO membrane? It states that it should be flushed but never gets close to telling you how to do this. @ US $150.00 for a membrane, I'd sure like to know how to extend the life of these. All 3 of them. Edit 9/25. We asked this question and received a quick reply from iSpring ; thank you. This unit has an automatic flush so I don't need to do anything. Nice. F. This unit can be installed under sink as an On Demand unit. It does have a unit high pressure shut down sensor so when the sink faucet is shut off the unit shuts off. Open the faucet and the low pressure sensor turns it on. This would work well with refrigerator ice makers/water units and several other dedicated facets. It depends on your layout, needs, and what you have to work with. Ours is a full time water production into a 8000 gallon cistern. G. Buying filters and the RO membrane can be confusing with the way that they are described. Be careful so that you are buying the correct items. CONCLUSION: I've looked at a lot of systems. To import a system costs us around 38% more then the purchase price. Either we have a water solution that works or? Please feel free to ask questions or post comments.

This unit is very well designed. I like that it is all self-contained in a good solid frame with wheels. It has a pretty decent water output all by itself, but after I added the booster pump it really pushes it out. I filled a 1500 gallon swim spa in about 2 days. I only ran it for about 8-10 hours a day while filling the spa so it definitely seems to be hitting the rated 1000 GPD rating. I had a couple of questions and Sean from customer support was very helpful. This is my second system from iSpring and I have been very satisfied with the performance and customer support over the years.

We are on a well with very stinky water. I added all kinds of filters, chlorine injector, and water softener. Water looked and smelled great. But wait... After some time our clear dishes were all becoming etched and frosted looking when washed in the dishwasher. If water dried on our dark cars it would make light etching in the clear coat and when drying the cars the towels would get sticky and start streaking. After a LOT of research and multiple water tests being run, we found we have very high TDS (Total Dissolved Solids). Government recommends not to drink water above 500 TDS, ours was 998. Two ways to lower TDS; boil it (distill it), or use reverse osmosis. To get the capacity we needed most companies wanted thousands of dollars for huge systems. I didn't need whole house, but enough for kitchen and one faucet to wash cars. iSpring was by far the most helpful when I called vendors. Plus their RCS5T had plenty of capacity. We added a 40 gallon storage tank, pump, and 20 gallon pressure tank and ran separate lines. At startup we could not have been more thrilled. Even when we wiped the kitchen counter top it was now smooth and clean feeling. Eureka!!! However, after a few months we started to hear the RO system cycling off and on a lot when it was filling the tank and got near the top. I tried different float valves but got the same thing. I called iSpring and talked to Nick in Tech Support. He listened, repeated back how I had set it up to make sure he understood, and then explained what he thought the issue was. I was fully prepared to hear the float valves were crappy, or my whole idea was nuts (a couple of other companies basically told me that). Instead, he asked for a copy of the invoice and said he would send out replacement parts. On the third day after that I received a complete new RO Head. This is essentially a complete new RO assembled system minus the filters, connection fittings, and instructions. I disconnected the old system, connected the new system, and life is once again beautiful. The off/on cycling is gone. To say I could not find a better company, better product, and better support person than Nick to deal with is an understatement. Thank you iSpring and special thanks to Nick for truly listening, nailing the issue, and responding so well. Products and service like this are very hard to find. Nick made me feel like he was a partner in my project; not just there to deal with me. Talk about exceeding expectations... With the water we have, we will be staying with iSpring!!!

I have a huge warning to you. It will deliver a 16 Oz glass of water in about 18 seconds. Absolutely slow. Why, do you say? Bad pressure? Nope. It has a pump. Nope, that is not it. The machine is designed to do just that. Every single time you turn on the water, it washes the filter for 10 seconds. THEN gives you water. It just dribbles and you can hear your water drain out the waste water tube. Then you get water. If you get water, turn it off, then instantly get more, it washes the filter off again. You have to wait 10 seconds again. I have come to dread getting water out of this infuriating machine. I now turn it on, walk away and do something else. I find myself wasting water, time, and just drinking the tap water again. I really really wish I had seen that this machine does this; I would have never bought it. Does it filter good? Sure, I guess. The flavor is okay. I have not had it lab tested. I just hope it breaks soon so I can have an excuse to put it where it belongs. In the trash.

I bought this unit about 4 months ago with the intention of setting up a whole house RO system and I have been very happy with the product performance. It operates quietly, and has high volume output (as compared to other RO systems) as advertised. Customer support is domestically based and very helpful. Nick, in product support was able to help me find a replacement RO membrane when Amazon was out of stock. The unit itself is fairly simple, and all of the components appear easily replaceable. Setting up the rest of the system has been challenging though. I have very fine sand soils and very hard well water, and therefore use a sediment filter and water-softening pre-RO treatment. Even with the unit's diaphragm pump, the permeate pressure after treatment is not high enough for a whole house system. So I have the unit dispensing permeate to 84 gal and 119 gal pressure tanks operating between approx 5 and 25 psi. I also have two 12v 15amp, 5gpm RV diaphragm pumps operating between 40 and 60 psi supplying another 84 gal pressure tank. This setup provides between approx 80 and 100 gals of on demand storage. This creates the capability to take showers, run the dishwasher, and use the sinks at normal residential flows and pressures. When the high pressure tank empties, the twin diaphragm pumps are capable of refilling the 40-60 psi tank during high flow usage. Once the high pressure tank fills, the pressure drop on the low pressure side causes the unit to automatically start and refill the 5-25 psi pressure tanks until the RO unit's cutoff pressure is reached. The limitations of my system include difficulty running the washing machine, which use large volumes of water. I will probably replumb my house to have the cold water for the washing machine running directly off the water-softened well water, as well as the toilets. Additionally, the permeate from all RO systems is acidic, so replumbing is probably necessary at some point if you have copper pipes (I am planning on replumbing with pex pipe). I also have a UV light after the RO for bacteria control. As a side note, tying into existing plumbing, if there is bacteria present in your piping, can result in contamination of the new plumbing. Therefore, you should probably shock chlorinate the entire system at the same time as installation. My experience has been that setting up a whole house RO system is difficult and probably requires professional help unless you have a solid engineering background. The RCS5T unit itself, though, is equal to the RO treatment task in my opinion, and if I had to do things over I would still have bought it. In retrospect, I would have probably used higher voltage, lower amperage diaphragm pumps since finding adequate converters was difficult. I choose the DC diaphragm pumps because they are capable of running dry and don't require priming in the event the 5-25 psi tanks are completely drained. Hopefully this review is helpful to those of you out there trying the same thing since I have had a difficult time finding much information on how to setup such systems. A lot of it has been trial and error, with a few dead ends and a little bit of wasted money, but I feel like I am getting to where I want to be.

18 Months later and we are still going strong. This system has been truly set it and forget it. My TDS is still in the teens, so I don't anticipate replacing the RO membrane until the 3 year mark at least. I'll never buy a big box water filtration system again! UPDATE: For the price, this system should include a tank. I added a tank and it's worlds better now. Great water pressure on demand. Honestly, this system is probably overkill for a typical home. We may use a few gallons a day, if that, but we no longer suffer the annoyances of a lesser system. Previously, we had a WHER25 system. I added a manual pump, which was obnoxiously loud, to gain some pressure. If we filled one large pot with water, the tank was empty. We had to wait a half hour and endure the loud clicking noises to get more fresh water. No longer, must we suffer through. I expect many years of trouble free service. Also, iSpring has fantastic customer service. E-mailed them some questions, and they got right back with great answers to make things easier. The suggested putting the tank in the line BEFORE the last filter. This system is fantastically engineered and a breeze to install. It fits perfectly under my sink and gets me less than 10ppm tds. My only complaint is the water pressure. It's fine for the most part, but having a tank would make this system perfect. I'll update again after I've used this a while. First impressions are spectacular.

I've had my system now for several years running great. A conservative measured estimate says I've likely put about 30,000 gallons through this system (based on metered data averaged for the time I've had the machine) providing 100% of the drinking and cooking water for a large household. I bought it because it was reasonably priced, had a significantly better waste/clean ratio than the majority of systems used in homes today, and its ability to run continuously - where most under-counter systems take 24 hours to refill the small tank and slow to a drip once emptied. I have the unit in my mechanical room where it's plumbed to a Kul drink dispenser upstairs and a standard office-style water dispenser in my bar. I've been very happy with the machine for the reasons above - I bought it because I'm on a metered well (Colorado thing - limited to what your meter is permitted for; not a gallon more and you can't buy more) and I wanted to filter any possible contaminants out. RO systems can remove most any unwanted contaminants from a well, and I know there are some known contaminants here, including the excess minerals from my PH neutralizer. Our water tastes incredible, and I'm very picky. When I go anywhere on city water or unfiltered water, I can't stand the taste - so I tend to take my own anywhere I go. After many years of dutiful duty, I noticed some odd behavior with it running sometimes and not shutting off even after building pressure to where it should (which includes filling and pressurizing a remote tank upstairs). I reached out for some guidance on what to look at replacing to keep it running optimally, since we depend on it so much (not expecting any warranty given the age of the machine). Instead of the typical form letter from a support person who didn't even read the original request - I got a response from Sean where he clearly seemed to understand the issue and was already thinking what may be needed, while asking for some additional details. iSpring and Sean went above and beyond what I could've expected and are sending me the parts I need to make the machine good as new. I have quite a few products from iSpring around the house, including the RO system, storage tank, and spindown filter for my irrigation, and all appear to be top quality and work perfectly. I gladly stand behind any company that stands behind their products. I will continue to recommend their systems to anyone knowing they'll outperform other similar products, and come from an American company with exceptional customer support.
