This was a good buy, and so far so good. It was also nsf certified. Installed with no problems. Recommended.

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.

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!

Installation: Including the run to the store for a drill bit installation took me about 2 hours. I have never done anything like this before. Installation went without a hitch. The directions were clear, and all the parts were there.

Use: The water comes out clean, and clear and perfect tasting. My wife is very impressed.

Cons: You have to cycle the system (fill up the tank, and run it out) 3 times before you can use it. This means no clean water for a day after installation. This generates a good deal of waste water, so it constantly has a running water noise after you have taken a good amount of water from the tank.

I purchased the 5 stage instead of 4 stage system. It was working for six month and then output rate of water from the faucet start to drop. I changed the water filter and carbon filter but the rate of output was still the same (low output). I changed the membrane but no water came out from the faucet. The customer support doesn’t reply your mail. I know this is a defect product and you should try some other brand.
