FS-TFC 5-Stage Reverse Osmosis Water Filtration System 100GPD Fast Flow Plus Extra 4 Filter for Free (FS-RO-100G-A)

The media could not be loaded. I’m not often this impressed, but I gotta say I AM with this under-sink RO system!I bought a house in the country thats on well water, and while the water tested great, its hard water with a lot of calcium in it. The calcium deposits leave behind a a grainy/crystalized powder that ruined a Kurg coffee maker and an Ice Maker and we also discovered that my wife has a sensitivity to the heavy calcium and it has caused some health issues for her.I priced out a whole home system, but thats out of my budget. I discovered these under-sink systems that I can install myself and were WAY more affordable. I chose this system because it was the most compact 5 stage RO system I could find. This kitchen hasen’t been remodeled since the early 90’s and i have limited space under the sink.Installation was EASY, took less then 2 hours, and the kit contained everything needed (except for a few basic hand tools; drill, crescent wrench, and a few wood screws).After turning the water back on and checking for leaks (none) it took about 2 hours for the system to fully fill up (my well is set to 45/80 psi), then a quick system flush…. And now we have beautiful, clean, healthy RO water, and it tastes Great! Good for my appliances and healthier for my wife. Home Run!All from a kit for under $150.00 AND it came with a set of replacement filters to!

We purchased this unit, wondering if it was going to give us better water. We have a well and a water softener and my wife didn't love the taste of the water and I didn't like to use the water softener for working with plants.Our configuration was to just run the RO to the refrigerator so we didn't use the faucet.The start of this story was not super, but after the outstanding customer support I was able to install and had great tasting water. It did the job we were looking for it to do. 5 start rating for unit and customer service.More details:What I loved about this unit is that it had literally everything I needed to put it in.I have to say, this is the first time I've used the quick connect and it was intimidating and worrisome. But after using it and learning that you just have to push the outside ring inwards to get the pipe out and the little blue c rings keep that ring out, thus not allowing the plastic pipe to come out unwanted, I was relived. And they are so easy to work with, it is almost embarrasingly easy!The seller ships the unit with a pretty much plug and play manner, but also includes extras like water line, multiple quick connect adapters, the valve you can use and the sink faucet. Even Teflon tape.As with most instructions, reading them made the installation easier. Even the diagram on the instructions to take off the pipe would have saved me watching youtube videos on the topic.To install, you basically have to connect 4 lines to/from the unit. IN, OUT, DRAIN and TANK.I installed it in phases by connecting a 1/4" plastic pipe to the quick connect, into a 1gal water container.* starting at the line going into the pressure regulator - making sure water was coming from the line* out of the regulator* out of the unit* final configuration before connecting it to my refrigeratorBottom line is this worked great and I am very pleased.One thing to remember with the RO systems. The water goes through a bunch of filtration and then goes through a membrane, and the pressure is controlled by a pressure valve.Therefore, if you run the water directly through the RO, the water doesn't run fast. it took about 7 minutes to fill 12 cups of water when I first connected it up. About 30 minutes later, the 12 cups took less than a minute....more...Once the system is in its final state and if you leave it be for 15 minutes or so, the water comes out of the faucet (in my case refrigerator) like you'd expect. This is caused by that water tank that comes with the unit.

I was a bit skeptical of how this was going to work or even if it would. I am a commercial appliance installer and find my way around with pretty much everything and believe that patience is important on this installation.I wanted a machine that had enough water flow to not cause my Leveluk K8 machine to get the low water volume error and thought it was a bit of a gamble on achieving this.My RV sits currently at a site which has substantial water pressure which ranges from 75 to 90 pounds.At first I had an issue with getting the tank to fill but learned there was air trapped in the RO cylinder. This problem was resolved by leaning the assembly of filter to the right and to the left and you will here the air purge if such instance occurs.I have not tried using this with the 45 psi RV pump but will do so at some point. I believe that removing some air from an emptied tank down to 5psi would still allow filling tank. That would probably then take it much longer than the 45 minutes which it currently is taking to fill.I am currently able to fill the tank empty of water with an air pressure of 8 psi which gives great water flow once full of water. I also filled it with only 5 psi and was still able to achieve enough water flow to run the k8. There certainly is no issue with water flow volume and is more than plentiful to run water to gather nearly a gallon of kangen water but no more than. This is perfect IMO.The instructions says to drill a hole 1/2 inch for the faucet which is definitely much larger than needs to be. I went much smaller just to satisfy my OCD and the event that I wish to remove and plug hole at some time in the future. I doubt that will be the case though. I used a bit size 7/8 for the faucet and it was a perfect hole size. It has taken about 4 full tanks being flushed before the odd taste is removed. I also read that the drain water keeps running on some reviews though I am not having such an issue as I have been checking it often to the point that I am now confident that it is working with zero issues. Well done with an excellent price.
