Product Questions

Can I drink the water that this RO/DI system makes ?
Question by: Tony Bily on May 19, 2016 12:55:00 PM
Great question!
DI water is not recommended for human consumption. Instead we do have our drinking water systems which use RO water. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on May 19, 2016 3:14:00 PM
Hi Connor- with the water saver system how many gallons of water does it take to produce one gallon of purified water?
Question by: Michele on May 7, 2016 12:10:00 PM
Great question! At 65 PSI the water saver systems will have roughly a 2:1 waste water to product water ratio, meaning for every gallon of product water produced, you will have roughly 2 gallons of waste.
Answer by: Carter (Admin) on May 10, 2016 3:27:00 PM
How much waste water will be produced for each gallon of ro/Di produced? Is the waste water good for use for anything else? Watering plants, drinking, etc...
Question by: Phong on May 8, 2016 1:23:00 AM
Great question!
There is no exact answer however typically this is a 2 part waste to 1 part product water. waste water can be used to water the lawn or plants however is not recommended for consumption. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on May 10, 2016 5:24:00 PM
I have a question about how the automatic shutoff valve works... Is it time based pressure based do I need to hook something up?

Question by: Elliott on Dec 2, 2016 9:38:00 PM
Great question! The auto shut off is engaged when there is back pressure on the product line. This back pressure builds through the use of a float valve or drinking water pressurized tank. No need for additional products. :-)
Answer by: Randy (Admin) on Dec 13, 2016 9:00:00 PM
Hi Connor - how many gallons (approximately) of water can I get with the system before replacing filters? How do I know that it is time to change filters? Thx in advance!
Question by: Reza S on Mar 15, 2016 10:40:00 PM
Great question!
This will vary quite a bit depending on the quality of the water, as well as time between producing water. On average the membrane will last several thousand gallons. The membrane should have a rejection rate of 99% which means if the numbers (after flushing) are above 1-3% of your source water it is a good idea to change (typically between 1-10 TDS) The Sediment filter, Carbon Block and DI resin will need to be changed much more often typically 6 months to 1 year. The DI resin can be changed when the color is yellow or the TDS coming out is above 0. The Carbon Block and Sediment filter will be difficult to tell however if the pressure drops it will need to be changed as well as the sediment filter will change colors when it removes quite a bit of larger particles. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 16, 2016 11:02:00 AM
Will it do harm if I don't use the system close to its maximum output ? I would like to buy the 6 stage 150 but my water demand would not require that much now. I don't want to buy a smaller system as a plan on upsizing my tanks towards the end of the year. Id be making about 50 gals a week
Thank for all Infomation I've learned from watching your channel
Question by: Joe on Mar 16, 2016 5:20:00 PM
Great question!
This will not cuase any harm! As long as the system is run weekly with water flowing through it will work great! You do not want to store the unit for extended periods as the filters may deplete when dried. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 16, 2016 6:40:00 PM
i bought this unit a bout 2 years ago and replaced the membranes once since ive had it and just put the same 75 gpd membranes in that it came with. my question is can i replace the 75 gpd membranes with the 100 or the 150 gpd membranes in the same housings or will it only accept the 75s
Question by: Garrett C Crance on Nov 6, 2016 10:38:00 AM
Great question! You could replace them with the 100/150 GPD membranes, however doing so will drastically reduce the rejection rate from the membranes, causing much higher TDS coming out of the membranes. This will lead to very fast DI Resin consumption rates and poorer water quality. You would also need to change the flow restrictor in order to change those. :-)

Answer by: Randy (Admin) on Nov 8, 2016 4:30:00 PM
So are those two 75gpd membranes for this unit=150gph? Also just make sure, 150gph flow restrictor?
Question by: Patrick Cezar on Jan 14, 2016 3:11:00 AM
Great question!
The 150 GPD unitl will have two 75 GPD membranes. The flow restrictor will be the same Flow 550 as with the standard 75 GPD membrane as the water will flow through both membranes in series causing the restriction to be the same amount. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 14, 2016 12:13:00 PM
does this RO/DI system come with a flush kit ?
Question by: Tony Bily on Jun 15, 2016 3:39:00 PM
Great question!
This Unit will include the membrane flush valve on the waste water line. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jun 15, 2016 3:53:00 PM
Will this work with 400 ppm city tap water ? will it zero out ?
Question by: Diogo on Nov 24, 2016 12:59:00 PM
Great question! The best filtration that you can have from a single RO membrane is 98% rejection rate, in which case, with 400ppm you can expect TDS reduction to around 8-12 TDS. It is not recommended to use the 150GPD upgrades for high TDS product water over 250ppm, due to the reduced rejection that will come from feeding the second membrane from the first membrane's waste water. Ryan talks about this in the video link below! :-)
Answer by: Randy (Admin) on Nov 25, 2016 7:46:00 AM
Does this ro di unit have the automatic flush system on it
Question by: John putman on Nov 24, 2016 3:25:00 PM
Great quesiton! Our units do not include an automatic flushing system, but this unit does include a flush valve that you manually have to manipulate. In order to incorporate an auto flushing system, you would need the products listed in the links below. :-)
Answer by: Randy (Admin) on Nov 25, 2016 7:42:00 AM
Hi, I have an older 5-stage chloramines plus system I've been using for about 5-yrs. Recently upgraded to the Aquatech booster pump and 150gpd upgrade kit (amazing upgrade I must add, worth every penny). I've noticed all the newer systems don't have the carbon 2nd stage that is in my older system. Should I change setup on my next filter recharge?

Currently running: sediment filter, activated carbon, chloramines carbon block, 2x serial RO, single DI stage.
Question by: Angelo on Mar 30, 2016 8:57:00 PM
Great question!
Ideally the best filter change will be the 5 stage universal replacement kit. This will have a single sediment, two 1 micron carbon blocks (Ideal for chloramine removal) and a DI resin bag. I have included the link below. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 4, 2016 10:40:00 AM
Can I put two 150gpd membranes on this unit? Will I need more psi pressure going in? Or what about the flow restrictor? Will I need to get a 300gpd restrictor? Or will the 150gpd be okay? Do u carry a 300gpd restrictor?
Question by: Patrick Cezar on Jan 14, 2016 2:18:00 PM
Great question!
You can place two 150 GPD membrane in the housings, you will want increased pressure a minimum of around 65-70 PSI. In addition to the membrane you will need to replace the flow restrictor from one rated for the 75 GPD (550mL) to a larger 150 (800mL) Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 14, 2016 6:28:00 PM
Does this unit require a booster pump?
Question by: chris kooi on Apr 27, 2016 4:51:00 PM
It depends on your homes water pressure.
If you PSI rating is below 50 a booster pump would be recommended.
Answer by: Connor (Admin) on Apr 27, 2016 5:25:00 PM
What water pressure do I need to use this system and does it include a pressure canister and pump? Thank you
Question by: JoEllen on Aug 25, 2015 2:13:00 AM
Great question!
This system will require 50psi to run efficiently, the unit will ship with everything that is pictured on the website. This unfortunately does not include a pressurized canister or a booster pump, these can however be purchased separately if needed. Feel free to let us know if you have any further questions.
Answer by: Connor (Admin) on Aug 25, 2015 11:11:00 AM
If I purchase the 6 stage water saver plus and don't want any drinking water option, what do I then need to add to store and dispense the water?
Question by: David Barnes on Jan 16, 2017 4:12:00 PM
Great question! Many customers fill containers of just RO water for storage and drinking purposes. You can easily collect your RO only water by adding a "Tee" fitting between the RO unit and the DI stages. This will allow you to choose when you want to collect RO water, or when you want to collect DI water. All you will need is a push-connect "Tee" fitting and a ball valve, listed in the links below. :-) (Just be sure to get the 1/4" sizes!)
Answer by: Randy (Admin) on Jan 16, 2017 5:34:00 PM
What system do would be best if im using well water?
Question by: Peter on Nov 8, 2016 9:17:00 AM
Great question! A 6 stage system should be a proper fit for a well water system, however most well water comes with a high sediment content. In that case, I would also recommend an additional sediment filter stage. In order to incorporate that, I would purchase the additional canister listed below as well as another sediment filter. :-)
Answer by: Randy (Admin) on Nov 8, 2016 6:30:00 PM
Hello. Will it be possible to make this unit for both purposes - drinking and reef? I mean if I install a splitting valve - can I switch between reef and drinking hose.
Question by: Emi on Nov 8, 2016 9:45:00 AM
Great question! You can easily add a 3-way ball valve between the RO membrane and the DI Resin canisters. That would allow for you to divert the RO only water to a pressurized tank, in order to utilize it for drinking purposes. :-)
Answer by: Randy (Admin) on Nov 8, 2016 6:32:00 PM
Is the 150 GPD water saver filter already attached to the system or is there some assembly required? Thanks.
Question by: Michael Nelson on May 15, 2015 9:31:00 AM
Great question, our water saver units are shipped with both RO membranes already installed. The DI canisters will be shipped separate however installation is as easy as plugging in the product water lines. Feel free to give us a call if you have any questions!
Answer by: Connor (Admin) on May 15, 2015 1:10:00 PM
Our house has a well with hard water, so we have a water softener. Is it recommended or not recommended to feed the RO/DI with the softened water?
Question by: Christal on Mar 21, 2016 4:44:00 PM
Great question!
it is recommended to use soft water to run into the RO system. This will help to preserve the life of the membrane longer. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 22, 2016 11:17:00 AM
Is there a flush valve for each membrane included with this system?
Question by: Charles Adie on Jan 8, 2017 1:42:00 AM
Hey there! This unit only includes a flush valve on the waste water line, which is intended to flush the RO membrane. There is no need for additional flush valves for any other canister. :-)
Answer by: Randy (Admin) on Jan 10, 2017 3:18:00 PM
Hi, I have had the 6 stage Universal Water Saver plus RO/DI system. I am confused at which position the black valve needs to be when flushing? When I turn the valve straight with the water line, as indicated to the "Flow" position, my water pressure with pump on, drops to 40psi. That is the flush position correct?
However, when I turn the black flush valve to the angled position, my water pressure increases to 65psi, so I assume this is not flushing, correct?
Question by: Robert Rainey on Dec 9, 2016 1:03:00 AM
Great question! You are absolutely correct. When making water, you will have a higher pressure and the valve should make a "L" shape. When flushing, the valve will be parallel with the line and the pressure will be lower. :-)
Answer by: Randy (Admin) on Dec 9, 2016 9:22:00 AM
Does this come with everything to fire the system up or do we need to buy the resin and blocks etc?
Question by: Chris Bruce on May 2, 2016 10:48:00 AM
Great question!
This unit will come with all filters included and ready to run! Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on May 3, 2016 6:45:00 PM
I have water pressure from a dug well that runs between 20 and 40 psi. What booster pump would you recommend to use? Or do you have different ideas that might work better? I am trying to produce water for a fresh water fish only tank. I am trying to learn what works and what is needed to make quality water, and how eficiently operate the systems. thanks for the help, Rick
Question by: Rick on Feb 1, 2016 4:25:00 PM
Great question!
For a standard RO system you will want the booster pump kit. This works with 1/4" tubing standard on most RO units. This will increase your pressure to an optimal range which works for your system. I have included a link below!
Answer by: Connor (Admin) on Feb 19, 2016 9:43:00 AM
Hi... is the 150gpd upgrade kit just an additional/second 75gpd Dow Filmtec membrane? The quick review doesn't mention that.
Question by: Steve on Sep 21, 2015 4:57:00 AM
Great question!
The 150GPD upgrade kit is a second 75 GPD membrane to add to your existing unit. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Sep 21, 2015 4:40:00 PM
From what I can find on your website, the BRS Universal carbon blocks have a capacity of 3,500 gallons for water with 3ppm chloramines. What I am trying to determine is that since this filter has two of the Universal carbon blocks, is it then rated for 7,000 gallons of water (input, not production).

Also, generally speaking, how many gallons is a single canister of DI resin good for and what assumed TDS input is that based on?
Question by: Christopher Sanchez on May 16, 2016 9:42:00 PM
Great question! Unfortunately due to vastly varying water quality, filter longevity is directly dependent on your local water quality. A rough average is 6-8 months for carbon block filters.
Answer by: Carter (Admin) on May 24, 2016 11:26:00 AM
I have read on other water treatment sites that they recommend removing the membrane and all filters and sanitizing the RO system when replacing the filters. Do you guys recommend sanitizing your systems at any point? If so how is the best way to do that? I have the 150gpd universal system that I also use for drinking water.
Question by: Dustin Carroll on Nov 29, 2016 11:39:00 AM
Great question! It is recommended to sanitize your drinking water system annually or even biannually. The way we do that here at BRS is to remove all filters, including the RO membrane, drain the pressurized tank, add a 1/4 teaspoon of bleach to the first stage, run the system until the auto shut off engages. After that, let the system sit for 24hrs. Be sure to thoroughly rinse the system prior to adding the filters and drain and fill the pressurized tank a few times before putting back in use. :)

Why my ro/di never reeds cero
Question by: Ginno on May 3, 2016 10:55:00 PM
Hey there,
There are many reasons for non 0 readings. Ensure that the membrane and filters are new and not depleted. Additionally proper flushing of the membrane will need to occur before and after each use. For troubleshooting please contact our customer support team via email or phones!
Answer by: Connor (Admin) on May 4, 2016 2:03:00 PM
I'm looking for a replacement filter set for this unit, but i'm a little confused. I see the direct replacement set that has the same filters but I also see the 6 stage Chloramine filter set. I have high chloramines in my unfiltered water so I'm not sure which filter set is appropriate?
Question by: Daniel Liguori on Jan 22, 2016 1:56:00 PM
Hey there,
we have a few models available. The best for Chloramines is the 6 stage universal replacement in the link below. The other models are typically older versions and will not be quite as effective at removing chloramines. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 28, 2016 2:10:00 PM

Is it safe to drink the RO water Produced by the 6 stage universal water saver plus? ( I would like to hook up the drinking kit/tank in between the RO filters and the DI filters.)
Question by: Kevin Eichelberger on Jan 24, 2016 8:32:00 PM
Great question,
Unfortunately the RO/DI systems we have with TDS meter, Pressure gauge and membrane flush valve are not NSF certified. We cannot recommend using not NSF certified components with drinking water. Feel free to let us know if you have any further questions.

Universal systems: Designed to be best in industry filtration for chloramines, chlorine and well water as well as cover the widest array of contaminates. This is the ideal solution if you simply want to know you have the best filtration available.


*If you are unsure if your city uses chlorine or chloramines you can use a LaMotte Insta-Test Free & Total Chlorine & Chloramine Test Strip or call your city's water treatment facility. If you don't want to bother with that, get the Universal system and know you are covered. Over 40% of municipal water supplies are now treated with hard to remove chloramines. This number is growing everyday so we recommend to the Unversal systems. If you select a Value system today, it is future proof and fully upgradeable. We offer Value to Universal Upgrade Kits which are super easy to install.

  • Best of the best By Donnie on 4/7/2017

    This is amazing! I finally got something worth what I paid for. The water I've been buying had 9 TDS. This Universal water saver RO/DI is a beast!! My water TDS is 0! What a difference. I was hope for a little difference but got the best surprise ever! Thankyou BRS for your outstanding products.
  • Awesome.... nuff said? By Joseph on 3/12/2017

    As can be seen, by all of the other reviews this is a great product. Easy to use, easy to set up, and well built. Nothing feels cheap or that it might break anytime soon. I have been very happy with this RO/DI unit. I would highly recommend it to anyone tired of making trips to the LFS or wanting the peace of mind that the water they are putting into their tank is clean and pure. Thanks BRS!
  • Must have By Chris on 3/9/2017

    Great product. Definitely a upgrade from previous equipment.
  • High Quality Product By Adam on 2/27/2017

    I have been looking for a RODI system for some time. Lots of cheaper options available, but they are not built for chloramines and only filter to 5 microns. I am VERY HAPPY I spent the extra money and purchased the RODI unit from BRS. Shipping was on time, the unit was securely packaged and in great shape. This RODI unit is build like a tank! Clearly this is a quality product.
    All the instructions and adaptor pieces were included. I am very happy with this unit, and I can't wait to start producing water.
  • Fantastic Product... By Gerry on 2/24/2017

    Reefer of 30+ years here. Just getting back into the hobby. Wish I had this quality of product back then. Fabricated with very high grade materials. Robust, efficient design which produces quality high grade water. My City uses Chloramines in our water, but the BRS RO/DI unit eliminated all traces of said contaminants rendering pure H2O for my reef inhabitants. I can even see them smiling. Keep up the great work BRS. You guys rock.
  • Great rodi By Christopher on 2/22/2017

    Have been using for over a year now and works flawlessly comes with everything you need to hook up to almost any water source
  • excellant RO-DI !!!!!!!!! By TURTLE on 2/18/2017

  • Another Home Run for BRS By William on 2/18/2017

    I've been avoiding spending the money on the big boy water saver plus 150, but I finally did it. I grew tired of waiting on our small RO system under our kitchen sink, because it moves water at a glacial pace. So, I finally bit the bullet and I am extremely impressed with the build quality, ease of installation as well as the flow. Our county water system doesn't even have chloramines, but the DI resin is a bit of extra security for me. Great Product and it's worth every penny.
  • Must have By Jimmy on 1/30/2017

    Great product. love the quality of water this produces. only negative is that it took 2 days to fill my system.
  • Great System By Zachariah on 1/27/2017

    Everything I want/need for perfect water. All of the housings and connections are high quality. Pressure gauge, TDS meter and flush valve are icing on the cake.
  • Excellent product By Brian on 1/19/2017

    Seems very well built. Installation was straight forward and was able to set up my new tank with this no problems.
  • Excellent value and performance By Christopher on 1/19/2017

    I really enjoy this RO/DI, I think it is my favorite over previous unit. To improve on this, I have added a pressure gage between the carbon filter and RO membranes, which lets me monitor pressure loss through the sediment and carbon filters. I have also added an inline TDS meter on the pre-RO water and the RO waste. I can compare the pre-RO water to the included TDS channel 1 and determine my RO removal efficiency. Also, from the TDS of incoming water, waste water and post-RO/pre-DI, I can calculate my RO waste ratio. Finally, I added a waste line and valve off my RO to prevent TDS creep from wasting my DI resin so rapidly. It is disappointing that after 20 years in this hobby and everyone still pushes auto flush valves on their RO units but no one makes an auto waste valve for the RO.
