APEC Water Systems RO-90 Ultimate Series Top Tier Supreme Certified High Output 90 GPD Ultra Safe Reverse Osmosis Drinking Water Filter System, Chrome Faucet

This is my second RO-PH90 system. Simply one of the best systems on the market, in my opinion. Uses genuine Dow filmtec reverse osmosis membrane. As anyone familiar with RO knows, filmtec membranes are the gold standard and rank among the elite in rejection rates. This is not your generic RO bought in a hardware store, although some large chains carry it. Input TDS = ~225 ppm, output TDS = ~15-20ppm. Does the job. Have not tested PH yet. Water tastes great as it does with my first system. Change your pre filters once per year or at the recommended %TDS interval and expect this RO membrane to last its full schedule of 3-5 years. This is very important. Incoming water pressure must be at least 50psi in my opinion, for this system to operate as intended. At 75psi, outgoing pressure is like a dream, even with 1/4'' stock tubing. Fills glasses quickly. Consider the 3/8" output upgrade if your input pressure hovers at 50psi as it did with my first unit. RO systems thrive on incoming water pressure, this is the most important aspect of setup! Do not skip! Simple setup as usual, although this time I needed a booster pump, incoming was 40psi at best. Remember, it can fluctuate significantly during high demand/peak times. Plan a few hours for someone not so mechanically inclined. John Guest quick connect fittings are painless. Manual is very thorough, follow each step carefully and no problems should arise. If they do, customer support is USA based and very helpful. Download and read the manual available on their website before purchasing so you know what items and skill level are required. Anyone with a few tools and willful attitude will have zero problems. Easily found an Aquatec CDP6800 kit on Ebay for $108 that is perfect for this system. Came with all needed lines, pressure gauge, shutoff solenoid, pressure switch, pump and transformer. Make sure to have a sediment filter before the pump if you want it to last. Of course, APEC also offers a version pre outfitted with either permeate or booster pump although you will need your own gauge I believe. If planning on wanting 3/8" output upgrade for PH model, please go directly though APEC to purchase with it pre installed. Do not buy the output kit here on Amazon and expect it to fit the PH filter on your unit, it will not. It is for 5 stage only. You would then have to buy a 3/8" PH filter from APEC, about $40. Save yourself some time and money going directly through APEC for the upgrade route. Not much else to say, please READ the manual and you will not have to think about this system but a few times a year for TDS tests and scheduled filter changes. Good luck!

Great product! Very high quality components. Easy to install. Great customer service. My local municipal water has TDS around 330. The filtered water comes out around 10 and tastes great! I am using the system without the tank. You can do this by modify the tubing and connect the filtered output of the ro-membrane to the 5th stage filter directly (bypass/remove the T that feeds the tank and the 5th stage filter, very easy with quick connect used on the APEC system). I use glass pitchers to hold the water. It takes about 5 minutes for the RO-90 to fill up a 2-quart ikea glass pitcher (half gallon). Why would you want to use the system without the tank? To get the best tasting water and not have to worry about whether the tank material is safe or not. For the RO tank to work, the water has to be held inside a bladder in the tank, so that the air pressure around the bladder can push the water out when you need it. For this to work, the bladder has to be a flexible material that can expand and shrink as needed. The type of food grade material that is suitable for this purpose is limited. The material being used is polypropylene and butyl. Now, while this should be a safe material to use, it does add an after taste to the water, especially if the water has been sitting in the tank for a while. That's why there's a 5th stage carbon filter, to filter out the tank taste. But having an after taste that needs to be filtered out does imply that the tank material affects the water. If you don't believe me, just read the Watts RO system reviews on amazon. Many are complaining about plastic water taste. The bladder also ages, and has an expected life of 8-10 years due to all the expansion and contraction. While I am sure the tank material used by APEC is better than the one in the Watts system, why get yourself into this situation at all? Just bypass the tank and store the filtered water in a glass pitcher. Glass is arguably the best material on earth to hold purified drinking water, and will not leach into or affect the water taste in any way. Bypassing the tank also allows you to have explicitly control over when to produce the filtered water. Tap water is generally better quality in the evening when everyone around is also using water. It is less good in the morning when the water has been sitting idle in aging pipes for hours. This is why when your local municipal utility conducts water tests, they usually flush out the water for a few minutes. My TDS test confirms this. Filtered water in late evening has TDS less than 10, while in early morning is around 20-25. I did contact APEC system and was very impressed by their customer support.

Replaced a system that went bad. Easy Install - local company wanted $699 so I tried it myself. I'm NOT handy but all the harder work was already done at my house for the other system (drain hole to drain pipe/spigot install in the countertop/t connector and hose to my refrigerator). I feel I could have done a brand new install myself just watching the youtube videos that are easy to find. This was so inexpensive so I ordered the kit. Everything went smoothly except the prior install had a 3/8" hose coming from the spigot T valve because the prior system had a 3/8" connector on the system itself. Nighttime dash to lowes for a (SharkBite Push to Connect 3/8 in. PTC X 1/4 in. D PTC Polypropylene Coupling) and some extra 1/4" hose just in case... and I'm making water!

Very good quality RO filter Decent manual and instructions for installation So far so good Only had leakage from the needle valve however fixed the issue with using more teflon tape inside and wrapping outside with water leakage pipe repair tape. Now working perfectly

Es un sistema super padre, fácil de instalar aún cuando tuve que perforar granito, pero eso es otra cosa, las instrucciones son sencillas, considerar colocar muy bien el teflón en las terminaciones de metal y contar con la herramienta necesaria, el tiempo de llenado fue poco más de una hora ya que cuento con bomba de presión para todo el sistema hidráulico. Consideren tener buena presión o instalar una bomba con el sistema. No tiene sabor y no tiene acidez.

Excelente aunque en mi ciudad necesito ayuda de una bomba presurizadora pero más que eso funciona muy bien

Tout était parfait de l installation à l utilisation

Waited a few weeks before reviewing... now I have been drinking the water for a few weeks, I must say I really like it. I am on a well that was dug last year at 160ft. My water is very hard and has over 700ppm of minerals but is otherwise great quality, no bacteria, no iron or other difficult to treat problems, just very mineral like it was expected in my area. So I installed a water softener to get the hardness down to less than one grain...in order to get ready for RO. I was looking for a good quality RO system with made in USA or Canada filters. My most important criteria was to get a real Dow membrane which this model has. So, on to this RO unit... Installation was done in about 2 hours. I am very handy and this was very easy. No leaks, no fuss... clear instruction (which is a frequent complaint with cheep systems). Every thing is high quality, the filter holders, the faucet and all of the hardware is very good... Water tasted a little metalic the first few days... figure it was the system flushing out (tank and filters). Now don't worry about some black stuff in the first few flushes as this is the loose carbon in the carbon filters, they all do that (all those I have owned...they flush themselves...) . So what I did was drain the tank every time I passed by it in the first few days... then the water taste cleared up real nice. It now tastes like bottled water... Now, my input is over 700ppm of dissolved solids (varies between 700 and 720)... when I measure the output of this system, it hovers around 20ppm... now that is a 97.3% rejection by the membrane... good job Dow Filmtec ... That is why I wanted an American made membrane... Now I am not worried about chlorine as I get my water from a well but I also liked the fact that it has 2 carbon stages for other agricultural chemicals... I would definitely recommend this unit... I am very pleased with the value and ease of installation...
