I got this system for the tough Tijuana water which is microbiologically clean, but has too much chemicals and low water pressure. The installation went straight forward and took about 90 minutes. My only con (thus 4 stars) is the instructions had many errors but with a little common sense I figure it all out. After 3 full tank cycles the water came out crystal clear and with no taste or smell. Just remember to test your water pressure before you buy. Most RO systems need 40 to 50 psi to work. Mine was around 55 so no booster pump needed. Overall, great little well built system.

Watt RO-TFM-4SV Premier 4-Stage Reverse Osmosis System

I had been using a GE two stage system for several years and the shutoff valve started to leak. After many attempts to repair it and finding out the part was $135.00 plus tax and shipping I decided to replace the whole system. I was happy with the GE and its quality seemed ok. I had a plumber install the GE because some parts of the installation was really difficult.. attaching the lines to the faucet was a nightmare, partly because of the design and partly because of its hard to reach location. I installed the Watt myself. It was a straightforward process and took about an hour. The hoses and connectors on the Watt seemed better.. and the overall quality of the Watt system seemed as good or better than the GE. The water quality is great.. I had paid $250 for the GE system several years ago.. the Watt was $169.. and its a three stage system vs a two.. and.. the water holding tank is bigger. I am very happy with this product. I only gave it 4 stars because they do not provide a filter wrench with the product. They say you get one when you buy a filter pack.

We just purchased the Watt 4-Stage filter. We were concerned about the difficulty of installation and quality of water. The installation was easier than we thought probably because my husband actually read the directions first (don''t tell him I said that, apparently reading the directions is considered a sign of weakness). We were also concerned about how the water would taste. We live in Southern California and the water is horrible. Neither one of us could drink it from the tap and had to order bottled water. The filtered water is now sweet and great tasting. The only annoying thing is the hissing sound it makes after filling a glass. That is why I only gave it 4 stars. If this will bother you I would suggest a different filter. Overall great water for the price!

This is an awesome little RO system. When set up properly it makes "NO noise" and is completely silent! We set this little system up in our RV. It fits nicely under the sink and there is still plenty of room for necessities. To make the system silent, all you have to do is by-pass the "Air Gap" portion of the faucet by not utilizing the RED and BLACK lines on the faucet. This gets rid of the hissing sound that plagues some of these faucets. All you need is the BLUE line from the tank to the faucet. Also, I mounted the "Drain Saddle" to the vent pipe under the sink. This puts the water/brine from the "RED Waste Water" line into the drain pipe behind the grease trap. By mounting the saddle in this fashion, crud cannot back up into the "Drain Saddle" and the "running water" or "gurgling" sound cannot be heard because it is not mounted in the sink drains. The only part I needed to do this was a "Union" that I picked up at Home Depot for $3.50. Watts part #109. This "Union" is to join the 1/4" RED line and 3/8" BLACK line together before the 3/8" BLACK line goes into the "Drain Saddle".

The water out of this little system is great and I would recommend it to anyone! Because it is made by Watts, it should be easy to find filters in the years to come.

Installation was pretty easy, though the instructions are highly unprofessional. I really expect a company of this size to be able to print illustrations in the correct resolution. The diagrams in these instructions looked as if they had been printed from a low resolution GIF image on the web and then photocopied into the book. The device produces a surprisingly loud hissing noise while the tank is filling. I bought this primarily to filter silicates out of my drinking water for filling my aquarium, so I get to listen to the thing hiss for two or three hours while it fills. I have gotten accustomed to it, though.

All was great for the first three months after installation. Now the filtered water seems to be dramatically less pure than the unfiltered water. Suddenly, the golden diatom activity in my aquarium shot through the roof, and water changes using the filtered water seem to make it worse instead of better. The water in my espresso machine''s reservoir smells awful after only a few hours (and yes, I''ve cleaned it over and over). If it were possible, I would say that the filtered water is going down the drain and the wastewater is what''s going into the tank. I am going to disconnect this RO system and try another.
