Please confirm that this is NOT a reverse osmosis system? I do not want to buy an RO system which stores water in a tank under the sink!

Hi CandT, Yes, this is not a reverse osmosis system. It is an ultra filtration unit without a tank. Thanks, iSpring Water Systems

This not a reverse osmosis system. it is a stright through water filtration system. it does however, require adequate water pressure (mains pressure). I have it but my mains pressure isn't great so its slow but still works OK. I am satisfied / impressed with the quality of water that i get from it.

This is not a reverse osmosis system. There is no tank. The water runs directly through the filters and out of the spout.

No....it's not a RO system, it is just a filter system that is mounted under your sink.

this model is not the RO model. it includes filters, yes...but it is NOT a RO Unit. Please read the description. Thank you, -J

Well, there are three filter tubes, and this covers all of them - so I guess so. It doesn't have the Reverse Osmosis filter.

Hello Kimberly, yes, with any reverse osmosis system there is waste water, is usually 100% to the water you purify (3 gallons of purified water to 3 gallons of waste water). However, I do not know if this is the case with this system. This information I have about waste water is as old as the reverse osmosis technology is (about 25 years ago). I suspect the current info is the same but I do not know for sure. Sorry I couldn't be more help.-Pat Holland

Once the cold water feed is turned on, the water passes thru the filters and the outflow from the other side of the RO filter begins filling the holding tank. There is a shut-off valve for when the tank is full. The water pressure on the outflow side of the tank seems to build up automatically. When we drain the tank, such as needing over 1.5gal of RO water, the water pressure drops, but in a while, 15-30 min the pressure is self-restored. ONE RELATED IDEA..when we installed this system almost 6 yrs ago, we tapped the outflow line and tied in the water going into our refrigerator's icemaker. We thus have RO water in our Ice...

No, I doubt it very much.The unit produces water fairly slowly and stores it in a small pressure tank at about 7 psi. It's certainly enough to provide drinking water. You will not have enough to do dishes and shower with RO water. I suppose if you collected the RO water in a large tank, then re-pressurized it to 40 psi, one could do a whole house. Also, the more water that is used, the sooner will the filters need changing $$$.

I would think you'd use a small goosneck faucet like other kitchen sink RO systems come with. If you're looking to use this with you're regular kitchen faucet, don't believe that will work. This is not designed as a "whole house" RO system.

I only use reverse osmosis water in the dog container. I don't know if there could be problems if using untreated water but I have no problems. Use 2 qt. unit and change water every few days.

People who say that the pump will operate as its own shut-off valve are right, in that it does stop allowing waste flow to drain when the RO membrane is not producing. However: Without the ASO valve, your RO system will kick on as soon as you open the faucet and tank pressure drops compared to line. Whether this is a problem depends on how much water you take at a time. Every time you fill a glass, the RO system will do a start-stop cycle. Unless the unit is in constant use, at the start of each cycle the water quality out of the membrane is going to be significantly worse than you would normally expect. There's very little you can do about this, it's a characteristic of RO membranes. The only solution is to reduce the number of start-stop cycles per amount of water produced. A regular ASO valve will accomplish this, in that it has an interval of pressure where it operates and will run your RO unit to fill your tank from, say, 1/2 full to 3/4 full. Since permeate pump-equipped RO systems don't care about the pressure differential across the RO membrane anymore, an ASO valve designed for a permeate pump system will have a different setpoint, and will run your pump when your tank is 3/4 to 7/8 full, for example. This still keeps the number of cycles down (the system will not inject sub-par quality water into your tank every time you fill a glass) *and* lets you take advantage of the higher initial flow pressure out of your tank and the (somewhat) increased storage quantity that comes with it. Hope this helped.

If you didn't see instant results your water needs more than filters. I had a $5000.00 kinetico system installed up stream of our home master filters. We also have a reverse osmosis system under kitchen sink. Check to see the cost of having a deep well put in or I can send you a pic of our setup. Either way is gonna cost you but better to invest than let the water destroy your homes plumbing.

Special membranes allow water to chemically bond to them and pass through, leaving behind most impurities. Unfortunately, fluoride is not one and you need an additional ion-exchange filter to get that out. I once lived in the San Juan islands in Washington and all our drinking water came from RO filtering of Puget Sound salt water. If you are going to buy the pictured unit that I did note that the instructions are virtually useless. You need to use JB Weld non-toxic epoxy (for aquatic use) on the thread of the small, RO unit screw in that's in the middle of the sink adapter or the joint will leak even if you use Teflon tape and pipe-thread sealer. You also have to drill a hole in a drain pipe and run a line from the "drain" fitting. Why? Because even if the instructions don't mention it, the drain runs constantly whenever the unit is filtering. (It stops when the storage tank is full.) Also, throw away the first 10 gallons you make, despite what they say. After that the water tastes great. If you aren't mechanically inclined, get a plumber to do the install.

The pre and post filter remove particles and they need to be replaced every six months. The RO Membrane (Reverse Osmosis) is a permeable membrane that lets pure water go through but not the bad stuff like arsenic, chlorine, etc. This cartridge is what makes the entire system work.We have well water and for my water I get about three years out of the RO Filter. My wife is the one with sensitive taste. When the water has no taste I know the RO is OK. When she tells me she can taste the water I know it's past time to change it.

Hi Kenny: For fluoride reduction we recommend a reverse osmosis system. Thank You, WaterFiltersOnline

I did not use the filters as we have a whole house system on our home as well and a reverse osmosis drinking water system. I only used the RO water in the fountian. My bulldog puppy has they unit chewed up with in a week :(

I don't think it matters what RO system you have. If it has the option for a reserve tank and the fitting works, then it should fill with water.

we have a whirlpool reverse osmosis system and our tank rusted and developed a leak. This save buying a whole new system. If it looks like the tank you have it should work. All we did was attach the water to the top of the tank and it began working.

No. This filter will not accomplish that. You will need a reverse osmosis system to do that. Also, please remember to take important mineral supplements when drinking that highly effective purification system water. The same goes for distilled water. If you can afford a reverse osmosis water purification system, it is the best choice of all for healthy water to drink. Another cost for such luxury is your water bill will go up (if you pay for metered water as I do), because I think it takes five gallons of water to make one gallon of purified water.
