Product Questions

Hi, just purchased my first reef tank and am still putting together all the items I need, next being a way to make RO/DI water. I'm convinced you guys make the best units available but am wondering how much water pressure is needed to pass through the filters. My home has well water and my pressure gauge on my well pump is at 50 and I've heard people having problems with this in pressures under 50
Question by: Mike on Apr 23, 2016 5:55:00 PM
Great question!
Under 40 PSI and the membrane will not perform to efficiency, 50 PSI is the recommended minimum operating pressure. Some things you can consider after setting up the unit will be to check the pressure, if it is too low you can add a booster pump or even permeate pump to increase the pressure slightly.

Hi, I Recently purchased this 75 gallon a day RO/DI value System.
In the features it notes an automatic shut off valve, How does that work? I tested it in a trash bin, and it overflowed.

Great question, all of our units come with the auto shut off valve, which it the square on the top of the unit with the blue and red line going in and out of it. in order for this to work there needs to be pressure in the DI (Blue) line. The pressure can be created by adding a manual shut off valve or a float valve. If you want it to be automatic, you will need to install a float valve in your DI water tank. We sell the float valve separate and all that needs to be done is install the valve and plug it into the DI line. I have attached a link below

At what level of chloramine would this filter no longer be appropriate? My city water is measuring between 1.3 and 1.8 ppm. Thank you!
Question by: Chris B on Apr 14, 2016 9:11:00 PM
Great question!
There is not an exact answer however if your city is using chloramines we recommend the dual carbon blocks on the 6 stage system to protect the life of your RO membrane.
Answer by: Connor (Admin) on Apr 19, 2016 3:46:00 PM
is it possible to upgrade the 4 stage basic system to a 5 or 6 stage by adding other additional canisters and filters inline to get more filtratation.
Question by: Scott on Jan 31, 2016 5:53:00 AM
Great question!
The systems are certainly able to be upgraded and we do have full upgrade kits available. I have included a link below.
Answer by: Connor (Admin) on Feb 10, 2016 3:36:00 PM
Do all of your RO/DI systems come with filters installed, such as the carbon block?
Question by: Ethan on Dec 5, 2015 11:55:00 PM
Great question!
All of our RO systems will come the included filters for initial use! Feel free to let us know if you have any further questions!

Hi, is it possible to install this reverse osmosis system into a kitchen sink? Thanks.
Question by: Jon Frerichs on May 2, 2016 8:08:00 PM
Great question!
This is unable to be installed as a feed line for a regular faucet. Instead can work as a secondary drinking water faucet with the purchase of the Add on Faucet kit.
Answer by: Connor (Admin) on May 3, 2016 5:38:00 PM
How long is the blue (output) line that comes with the unit? What is recommended (connectors/tubing) to extend this length?
Question by: Evan on Jan 21, 2016 3:35:00 PM
Great question!
There is 10' of tubing for each color included with the kit. For attaching additional tubing you can use the 1/4" union in the link below. Feel free to let us know if you have any further questions.
Answer by: Connor (Admin) on Jan 27, 2016 7:38:00 PM
if im filling 55 gallon drum with the rodi unit will it shut off when drum is full? if not can i link it to another device to do this?
Question by: Brad DuBois on May 17, 2016 10:33:00 AM
Great question!
The unit will shut off as long as you have the float valve installed on the ro container. The auto shut off valve included in the unit will cause this to shut off the waste and product water.

  • Excellent Results By KW on 9/26/2016

    Hooks up in about 5 minutes...I get at least 75 gal. per day of perfect water! Why spend more?
    This is the second one I've purchased.
  • Could be better By Aris on 9/15/2016

    All in all this product is great, but mine drips and is leaking and not sure if that's normal?
  • No leak! By Wes on 9/8/2016

    I've purchased quite a few similar filters from other places and they all leak. I intentionally did not do anything to this one and just hook it up, and it did not leak at all! Much better quality already. Let's hope it holds up well. Will report back if the status changes.
  • Good basic Filter By Eddie on 8/23/2016

    Very good basic filter. No leaks and everything is assembled. I'm not getting 0 tds but I think my meter needs to be calibrated and there is nothing wrong with the filter.
  • Finest Customer Service By Michael on 4/29/2016

    I purchased this unit as a new reefer starting my first tank. I was discouraged when my unit arrived with two broken connections but the BRS team overnighted me two new connections and they were simply awesome to fix this problem. Their customer service is the best I've ever encountered and has sold me as a lifetime customer! The system is simple to set up and of course of the highest quality producing nothing but 0ppm TDS
  • Up and running in no time thanks to all the fittings By 1611mac on 4/15/2016

    I am highly satisfied with this unit. When I opened the box and saw the method of packing I new the unit was going to be good. (If you care about your product you are going to pack it nicely.) I initially hooked this up to a spare bathroom sink to to grab some RODI to calibrate a ph meter. Hookup was a breeze due to the "sink" fittings. Two days later I mounted on the wall of my garage for a "temporary" permanent setup and it too when great due to the inclusion of an outdoor hose fitting. These may be "little" things but they indicate that BRS really does care about providing a good product. I had a small drip on the inlet fitting and I had a replacement in a few days. Thanks BRS! One highly satisfied customer!
  • best RO/DI system out there By mark skjerven on 3/23/2016

    I've had it for 2 days now and wow best thing ever used every one should have one no matter which system get one!
  • Great Product By Garrick on 3/15/2016

    It leaked a bit for me, i'm sure I can fix it
  • Awesome! By Paperpimp on 3/7/2016

    I bought this unit unsure of what I was going to get for the money. I was really surprised I have had other units priced little higher than this one and never got good results from them from day one. My city water had a real high TDS and with this 0 TDS didn't expect to get it to 0 from the start without some upgrades but it worked. Another wonderful thing is they give you the hookups that you need included also. Thats a money saver too. I was a first time buyer, but with the products and quality fast shipping. I will be buying a lot from these guys!
  • Great product By Tony on 2/22/2016

    I got this with the upgrade kit that comes with the pressure gage and tds meter and it was super easy to install I made it look just like the plus system great product from brs no cons
  • Wonderful product By James on 2/21/2016

    I have used this for about 150 gallons and i haven't noticed any depletion of the filters. BRS makes a quality product, and while their instructions are general for the other value RO/DI systems it is not a detraction from the product. The chlorine test kit that it comes with is super handy, and good for comparing your tap water to the final product.
  • Wonderful Experience By Rob on 2/19/2016

    Exellent quality product. Great prices and support. Wonderful buying experience. Thanks BRS
