Product Questions

Hi, I have a 4 stage 150 gph system for about 2 month now. Works fine, but from today, the TDS monitor shows 'HM' all the time. And seems the on/off button not response to any push, short or long.
Is the system have some issue or the TDS monitor out of order?

Question by: Jason Huang on Jun 4, 2016 10:06:00 AM
Great question!
If the display on the meter is showing 000 this will mean each line is working and the water coming out is pure. If the screen is blank not showing anything this could be a dead battery on the unit. Feel free to submit and email ticket with some photos if further support is needed.

I have the 75gpd system right now and want to upgrade to the 150gpd but i only run 50psi water pressure now i know that i wont get 150g but will i at least produce more then the 75gpd im getting now? I will upgrade later to a buster pump but i at least want to produce more water per hr. then i am now.
Question by: JIM YAMRY on Mar 19, 2016 10:38:00 AM
Great question!
You can certainly upgrade to the 150 kit which will produce more water than a standard membrane. Eventually a permeate pump or booster pump will be needed to keep performance up. Feel free to let us know if you have any further questions!

Hi, I have 3.5 ppm chlorine and chlorine on my most recent water test. Will the 4 stage value water saver plus system work for my reef tank?
Question by: Tim on Jul 1, 2016 9:24:00 PM
3.5 PPM of chlorine should be able to be handled just fine by our universal carbon blocks. They can last for up to 35,000 gallons when filtering chlorine!

I am looking for a way to save my DI resin. I currently get about 50 gal. from it. I suspect it is Co2. I was thinking about letting the water sit then pump it through but was wondering if there was a easier way. My idea is to drip the RO into a bucket then letting gravity take the water through a bulk head, through the DI and into another bucket. What do you think about this idea?
Question by: Charles Lewis on Apr 14, 2016 11:26:00 AM
Great question!
The ideal solution for CO2 is exactly as you have listed. With storing the RO water then running it through the DI resin via gravity. Often depending on the set up we do have to use a feed pump to push the water through the DI resin is the containers are mounted level. Feel free to let us know if you have any further questions!

Need an RO for a new 112 gallon tank and also want to do a sink faucet for drinking water what system would be best for me. Live in Fort Myers Florida area.
Question by: Brian on Mar 7, 2016 7:27:00 AM
Great question!
For a drinking and Reef system you will want our drinking and reef kit which comes with a separate pressurized tank to keep drinking water on hand and separate DI as it is DI resin is not recommended for human consumption. I have included a link below!

Hi, just talked to the water company. They use Sodium Hypochlorite. Would the BRS-4 work for that or do I need to go up to the BRS-6? Thank you.
Question by: Daniel Schmidt on May 25, 2016 10:07:00 AM
Great question! I would recommend the 6 stage for removal of the Sodium Hypochlorite, this is essentially liquid bleach, so an extra carbon block filter for added protection of the RO membrane would be good to have :)
Answer by: Carter (Admin) on May 26, 2016 1:51:00 PM
I just purchased this unit "BRS 4 STAGE VALUE WATER SAVER PLUS RO/DI SYSTEM - 150GPD". Should the output be closer to 1:1 or more like 2:1. I measured 2 cups of discharge and I got almost 2 cups of clean water, the flush kit valve is fully closed as shipped.
Question by: Charles Dennison III on Mar 9, 2016 10:07:00 AM
Great question!
The output will vary depending on source water quality and pressure, If the water is better with higher PSI the ratio will be closer to 1:1. Feel free to let us know if you have any further questions!

Does the 4 stage water saver plus get out all of the phosphates
Question by: John R Shiels on Apr 17, 2016 11:45:00 AM
This 4 stage system RO membrane and DI resin will remove phosphates from the source tap water. Feel free to let us know if you have any further questions!

I live in Brooklyn Park, MN and we use Water Softeners. Is it ok to run these RO units on a faucet that is running water off the water softener? Do you know if this will affect my aquarium and fishes? Or is it best to run these RO units on a faucet that is straight hard water? Is this Water Saver Unit the unit with the best RO/Waste water ratio you have?
Question by: moua on Mar 9, 2016 10:50:00 PM
Great question!
For life span of the RO membrane it is best to run our units after the water softener. The 150 GPD water saver is the best for reducing waste water currently available and will bring the waste closer to a 2:1 ratio. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 10, 2016 1:49:00 PM
When not in use (producing RO water), does the system turn off waste water automatically if the water supply is still pressurizing the system? I am planning on hooking this directly into a container with a float switch and do not prefer to have continuous waste run off while the system is not running and I am not home to turn off the supply valve
Question by: Daniel Hamilton on Apr 4, 2016 7:39:00 PM
Great question!
When the float valve is triggered or the blue product water line manually shut off the Auto Shut Off Valve will trigger and turn off the waste water line. The Auto Shut Off Valve can take a few minutes to trigger depending on the length of tubing in the system. Feel free to let us know if you have any further questions!

Does the 4 stage value water saver plus RO system filter out flouride?
Question by: Dan on Jul 10, 2016 8:36:00 PM
Hi Dan,
All of our RO systems use high quality TFC membranes which can reject up to 98% of fluoride in the source water.
Answer by: Charlie (Admin) on Jul 11, 2016 10:50:00 AM
How often should i have to replace an entire unit? (Our 4 stage is no longer producing at the rate it was and cartridges have been replaced.)
Question by: Merle on May 19, 2016 12:28:00 PM
If a pr-efilter cartridge replacement doesn't restore normal function to your unit, you may need to replace the RO membrane.

Full Details

All BRS RO/DI systems reflect the latest in reverse osmosis technology with updated filters, components and design updates.


Value systems:Designed to treat for chlorine, low volume chloramine usage and most well water*. Value systems are compact, portable, upgradeable and most importantly affordable.


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.

  • Huge money saver! By Carlos Z on 9/17/2016

    I had a few questions so I called the help line. The rep was a HUGE help giving me advice on how to set up the system. He gave me the confidence to buy it. Btw this is my first saltwater FOWLR tank ever.

    So I order the system and a adjustable float valve. Free shipping and arrived in a few days. Awesome. The packaging was very secure and padded.

    The system is 99% assembled! Super easy and comes with at least 10' of water line. Plenty for most applications. All fitting were included and I had it running in less than an hour.

    I did have a little rust appear below the pressure gauge where some water had dried and left a rust ring. I called customer service and we discussed it. We agreed to keep an eye on it. With a two year warranty I'm not worried. Great service, great product.
  • Excellent Unit By nnorton11 on 7/13/2016

    Im very impressed with this system. It came out of the box ready to go. It does a great job. Im very pleased with my purchase i would definitely recommend this unit.
  • works great!! By Marshall on 7/10/2016

    Filters work beautifully, BRS gives you everything you might need for possible connections. Was slightly worried about having enough pressure in Los Angeles but was happily surprised to find 60 PSI out of the kitchen sink. Making water like crazy, couldn't be happier with it.
  • Piece of Cake By Reggie on 6/26/2016

    Once I located the place to set up it was very simple. Piece of cake. I am pleased that everything that i need in a RO DI unit came with this. No need to add anything except a float valve. I'm good!
  • Very happy By Beans on 6/26/2016

    My first RO unit. Easy set up, works great. Very pleased with the unit.
  • WOW!!!! Why did I wait so long By chuck on 6/13/2016

    Not really sure why I waited so long to purchase this RO/DI unit...It was very easy to set up on my bathroom sink and the unit is sturdy enough to just sit on the floor without being mounted. It makes pure water and now I know that any makeup or water for my ATO is top quality water. I have a 60 gal cube with a med blue tang/ yellow tang four clown fish a watchman goby a coral beauty angel fish that I feed 3-4 times a day and my NO3 stays around 0.01 PO4 0.01 I do perform a 5 gal water change every week with reef crystals...Very happy and so is my tank.
  • Love my BRS RO/DI System By A.J. on 5/18/2016

    It is so much more convenient using this system then running to my LFS to get RO/DI water. Saves me a ton of time and money, considering every time I went to my LFS for water I would buy something, even if I didn’t really need it. If you factor that into your return on investment equation the system will pay for itself way quicker than you think. I’ve been running the system for about 6 months, producing about 10 gallons a week. So I have produced about 250 gallon. The DI resin is still all black and is holding strong. TDS levels are ZERO. If you’re like me and you over analyze what equipment you are buying, you will not be disappointed. Make the jump and buy this system, you won’t regret it.
    Last point – my pressure is only 50, so I do need to get a booster pump to prolong the life of my filters and resin, but even without a buster pump I still produce 5 gallons of water in about 48 min.
  • Freshwater fish love it too! By Rick on 5/16/2016

    Finally got it set up and super happy with the quality of water produced. Fish are responding in a most positive way. Thanks so much!
  • AWESOME highly recommend By Kman on 4/11/2016

    I bought this unit as a first RO/DI unit. I wasn't experienced with RO/DI or making my own water. I bought this back on 8/4/15. BulkReef was very helpful in answering all the question I had about the product. The unit came shipped and package extremely well. It was very simple to setup. BRS supply's you with everything you need to set it up. After letting the unit break in a little I was up and running making my own saltwater. I have not looked back since. Im very happy with the product and maintenance is extremely easy. Having the TDS meter is on the unit is very handy. I did not need a booster pump as my pressure stays at 60-61. I have some friends who use a 75GPD and it takes them longer to fill there cans up. This unit is well worth the money!!!!!!!
  • Great Value High Quality By Cave Man on 3/7/2016

    This is a great unit that produces near prefect H2O. I wish it was offered with the extra DI container. You will want it. As well consider an extra DI unit so you don't have to waste the last 10% of the DI resin. Also it tends to use the Resin a little faster then I expected. I had to replace it at 200 gallons. This will be improved by doing long runs of RODI instead of many short bursts.
  • Awsome! By Victor on 3/3/2016

    just did a 20 gallon nuvo kit with BRS and added this to my order. might be a little overkill for a 20 gallon tank but the price difference from the 75 gpd to this one is something you cant pass up. my location im able to get a pressure reading of 40, which is a little below what is recommended but im sure ill be alright. looking at filling up a 5 gallon bucket in about an hour. perfect for my water changes!
  • Great buy and Value By Zach on 2/19/2016

    I love this unit I have had it about 4 months now. It is much better built than the one it replaced in my setup. I have a 150G reef tank and in about 6 hours I fill up a 35gallon trash can with water for changes. The water saver plus is definitely the one to get in southern California. This unit produces very little waste water (~ 2:1) compared to the typical efficiency of 4:1.
