Product Description

Five Stage Residential Reverse Osmosis System 50 Gallons Per Day produces pure water much faster than most RO's sold in stores locally, which usually have only 25 GPD membranes or less! This system will refill your tank more than twice as fast. System features 5-stages of treatment: STAGE 1 - 5 micron sediment pre-filtration for mechanical reduction of rust and particulate, and provides membrane protection STAGE 2 - granular activated carbon pre-treatment filter STAGE 3 - activated carbon block for reduction of tastes, odors, chlorine, & organic impurities STAGE 4 - thin film composite Reverse Osmosis Membrane for reduction of dissolved solids, including the range of toxic heavy metals, plus Giardia & Cryptosporidium cysts STAGE 5 - activated in line carbon post-filtration for final polishing of off-tastes & odors Maintenance:Pre and post filters recommended change every six months for regular usage, or once a year in light usage. RO membrane: Change recommended based on periodic TDS rejection tests. Typical is every two years. Warranty: Components are warranted for one year from date of purchase, excluding membrane, pre & post filters. System comes with complete installation instructions and installation diagram. System dimensions: Main unit 18"H X 16"W X 6"D, Storage tank 11" dia. X 15" high, includes auto-shut off, 1/4" tank ball valve, install pack with feed water adapter, drain saddle, storage tank and faucet spout. Reverse osmosis typically wastes 3 to 4 gallons of water for every gallon it produces.

And the water tastes great!
I received this yesterday, as far as installation goes, I am no a plumber but it wasn't hard for me to figure out. first, the unit came missing some parts.
On the website, where they appear to sell to distributors, they claim the products are NSF and FDA certified.

It makes me so sad that I have to leave such an awful review, and I've contacted the seller many times giving them an opportunity for another solution, but they've given me no choice. I purchased this item in August 2010 hoping for floride/chlorine free safe drinking water. When I received the unit, I unpacked it, checked the "easy" instructions and after several hours of frustration, called our handyman. It took him 4 hours and two trips to the hardware store to buy parts. Wasn't a cheap install.

After installation, I began using the water for drinking, and also used it to fill our fountain. Our fountain immediately rusted and I grew concerned. I contacted the seller and they told me that they wouldn't recommend the water for contact with metal but that it's "totally safe" to drink. Really? I ordered a water test kit and found that the PH in the filtered drinking water was 4.5. I emailed the seller, scared to let my children drink the water after doing more research and finding that water with this PH was NOT recommended for drinking! Instead of letting me return the unit, they offered to sell me a part for $119 to rectify the problem. WHAT??? I decided to add minerals and lemon slices to the water and though still frustrated, didn't want to invest more into this system.

A month later, I noticed that the unit was leaking out of one of the cartridges. I called a plumber out who told me that the unit was defective and to return it. I contacted the sellers and was told that they recall no other correspondence and that they could not accept the return. I had to pay to have the unit removed as it was destroying my cabinetry...more expense. Now, it sits in my garage... I offered to pay for the return shipping and eat all of in installation and uninstallation costs ($400) later plus a ruined fountain...and they simply refused to respond.

Do NOT do business with this company! I also recommend that Amazon no longer allow them to sell.

This seems to be a great RO system once you figure out how to install it... The instructions that come with it are pretty poor. If you aren't familiar with a modest amount of plumbing, have someone else install it for you.

A few clues to make this go easier for you:

Not all the fittings that come with the system will necessarily work with YOUR current plumbing.

The color coded tubes didn't match the instructions. This doesn't matter EXCEPT FOR ONE: there is one tube with a little restricted fitting inserted. This is for your waste line. IT IS ABSOLUTELY NECESSARY TO GET THE SYSTEM TO OPERATE! This is what creates the back pressure for the system.

Looking from the front,
Your water input to the filter (from your cold water line) goes to the bottom right fitting (into the first big filter, it is labeled "IN" above the fitting.
Just above that is a "T" fitting, the open port goes to your tank.
They send a shutoff valve that goes on top of the tank that the nylon tube goes into.
On the left side of the membrane (lower horizontal cylinder) are 2 fittings, one used already, the other one goes to your drain (use the saddle valve provided).
The last tube goes on the left side of the top cylinder (your final filter) goes to your faucet.

Tips for your waste line:
IF you use an air gap faucet (required in some places, prevents drain backups from going into the RO system), the drain restrictor won't fit on the faucet end so turn the tube around and have the restrictor in the fitting towards the RO membrane. To use an air gap faucet, you will need to do some creative plumbing to get the different size tube from the faucet to your drain.

5 Stage Reverse Osmosis Water Filter System With Storage Tank Removes Fluoride

Even though I suspected that this seller has had issues with missing parts in the past, I ordered the item. Mea culpa!

Sure enough, the so-called "No. 1" locking push-cap intended to secure a tube to the No. 1 port was missing. This makes the ENTIRE device inoperable! And, I triple-checked the packaging!

Furthermore, the assembly instructions are poor - with no page numbers (required) to which to refer, as one example. Fortunately, I have put a unit VERY similar to this one (All purveyors apparently use the same supplier.) from another source, and so this was not too much of an impediment. A newbie will have trouble.

Failing a VERY quick response, I will discuss this problem with my Credit Card company, read: will demand full credit.

The shipping charge for this product is high; high enough so that the seller has an obligation to provide good Quality Assurance that will assure an ability for me to use the product quickly without this kind of folderol.

Being made off-shore doesn't help, either.

I will expect the missing part, tout suite, and some monetary compensation for my trouble and delay in using this item. Plan on it!

Finally, Amazon's excellent reputation has been sullied; it's time to drum this seller out of the family. Others that sell the same item for slightly more money are apparently better at providing a quality-packaged product.

Update as of 2-17-11

OK on your agreeing to send the missing part.

When will it arrive?
