Works exactly as it should - puts out 0 TDS RO/DI water on demand.

Received mine with a cracked piece but BRS customer service was fantastic and had the part shipped out immediately.

I have had this RO system for a few weeks now, so now I have it set up the way I want it, and it has been great. I use DI and filtered water probably differently than most people who have purchased BRS RO systems in the past. I have only a fresh water tropical fish tank, no reef tank. This system is so easy to configure it only took a few minutes to add a 3 way valve after the carbon filters, so I can get all the clean water I need for the fish tank, or drinking without using chemicals to neutralize the chloramines and other chemicals in my water. We don't like drinking DI or distilled water, so just clean filtered water is great for us. The DI water I use for indoor plant boxes, so now I don't have all the salts collecting in the soil and on the sides of the plant boxes, also use for room humidifier, so no more white powder collecting on the floor. Actually, anywhere distilled water is needed it is now easier to get and cheaper in the long run.

When I first started using the system I recorded the water pressure with the flush on and with the system making DI water with the flush off. Now I have a base line, so I can better tell if the sediment filter is getting full or the membrane is getting too old. May help in the future.

I noticed one reviewer who had leaks in his system, with over 30 tubing connections I wouldn't have been too upset if one leaked, but not one leak has been seen and I have used it for several hours. Tells me just how good the quality and the workmanship is on these systems. Keep up the good work BRS. I researched and compared every RO system I could find and this one may cost a little more than some others, but the quality of the components is the best.

All I can say is, it's a great buy! I was tired of having to drive to my LFS to get water then carry the water into the house, etc. But, the knowledge of my city water having ~1-4 ppm of chloramines in it has prevented me from getting a unit for a while. The guys at BRS explained that this unit would be perfect. It took about 2 mins to setup! After the initial system flush, I was making water. I will admit though, I was a little hesitant to use the water because of the chance of some chloramines getting through. So, I tested it in the water quality lab at my State's Aquarium (I volunteer there) using a new HACH spectrophotometer. Here's are the results, but keep in mind, this is a brand new unit:

Regular Tap Water
Free Chlorine: 0.87 mg/L
Total Chlorine: 2.72 mg/L
Ammonia: 0.863 ppm


10 min. Flush Water
Free Chlorine: 0.01 mg/L
Total Chlorine: 0.00 mg/L
Ammonia: 0.825 ppm

Final RO/DI Product Water
Free Chlorine: 0.00 mg/L
Total Chlorine: 0.00 mg/L
Ammonia: 0.00 ppm

It works!

Amazing system. I'm already looking to add the pressurized drinking water addon. Only issue I had was the unit as shipped leaked where the auto-shutoff was connected. After playing around with it, I noticed that their hose wasn't cut 100% smooth and straight, but had a little notch of plastic still attached. Recut with a razor blade. Problem solved. It also illustrated how careful the hose ends need to be cut to prevent leaking.

Thanks for my order BRS, I just hooked up my system and it works great the tds are zero.

This came nearly ready to go from BRS. The kit includes every possible water source connection you could ask for. This is my first ro/di unit so everything was completely new to me. Included instructions leave a little to be desired, but fortunately BRS has a great video online. I chose the saddle valve for a water connection, but unfortunately the valve included did not fit my pipe (3/4") so I had to purchase one from HD. So far, it's producing 0 TDS water with a respectable amount of waste water. What more could you ask for? Another fantastic product from BRS. I also like that the filter elements are easy to find and so affordable. Thanks BRS!

The unity clearly has a very high build quality. I had an issue with a missing part on the order and BRS took care of the situation very promptly. Will continue to order from them in the future!

purchased this product because i figured it should pay itself off within a few months. i found myself going to a LFS to pickup RO at least twice a week and that got old pretty quick. Everything you need to mount and get some 0 TDS water comes in this package! thank you BRS!

Recently started a brand new 130g (not including sump) tank and i found myself going to a LFS for 10 gallons of RO every few days. I figured I would save myself the trip and install one of these here at my office. It should pay itself off in a few months so im glad! Got it on sale too because it was on their deal of the day! Everything you need comes in this package to plumb the system! thank you BRS!

This thing works as advertised. I have almost exactly 40 PSI at the faucet, and it cranks out 75 gpd of water that has 2 ppm TDS going into the DI resin and 0 ppm TDS coming out of the DI resin. Works great in my tank.

I love this RO/DI, it comes with eerything that you will ever need. My water preasure is 60 psi from the tap without any kind of boosters os i get more than the 75 gallons a day that it is rated which is a nice little bonus.

I bought this ro/di unit after hauling water around town for almost a year. The money spent on this unit has paid for itself in 2 months. Make sure to get the adjustable float valve or the automatic water sensor shut off kit. Water comes out zero TDS after the DI resins. Our city water has chloromines in it and comes out of the faucet 150 grains hard on TDS meter. I searched around and looked at many other units and this was the way to go. Highly recommended.
