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!
Answer by: Valerie (Admin) on Jul 6, 2016 12:09:00 PM
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!
Answer by: Connor (Admin) on Apr 19, 2016 10:50:00 AM
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!
Answer by: Connor (Admin) on Mar 9, 2016 6:23:00 PM
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!

Question by: John R Shiels on Apr 17, 2016 11:45:00 AM
No answers yet. Be the first to answer the question!

Any suggestions on how to warm the water up to 77 degrees prior to the RO unit? I need to hook this up to a hose from outside. Is there a way to connect it to a storage container of heated water, then pump it through the RO unit? What would you suggest to accomplish this? I am sure the water from outside is around 50 degrees, so i would probably waste a lot more water without it heated, correct?
Question by: Joseph on Apr 10, 2017 9:53:00 PM
Hey there,
While the manufacturer data and testing was conducted with water at 77F, this is not practical for most real-world home applications and we don't recommend attempting to modify your water to meet this particular parameter. It is never recommended to mix our hot and cold water lines feeding the RO membrane, and the pressures required to operate the unit would be very hard to achieve outside of residential home water line pressure. Not to worry though. With proper pressure you can expect to get very close or up to the stated rejection rate and production rate without the need to warm the water. The fact is that while colder water does slow production slightly and can change the waste ratio, it also aids it better rejection of impurities without the need for as high a ratio of product to waste. The manufacturer data not only uses 77F as the standard, but is also only trying to achieve a 1 to 6 product to waste ratio, which most people wouldn't want.

Hope this helps!
Answer by: Zack (Admin) on Apr 23, 2017 7:32:00 PM
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!
Answer by: Connor (Admin) on Apr 8, 2016 2:05:00 PM
I am a home brewer and I am considering BRS 4 Stage Value Water Saver Plus RO/DI System - 150GPD, but I wanted to know if I could connect a couple of RO tanks, two or three 20 gallon tanks to it. I general only brew once or twice a week, each time using about 25 gallons. I was not sure if a different auto shut off valve would be needed for the larger 20 gallon tanks or if I would just need fitting to adapt to larger pipes/tubes. Also do you have adapters/fittings for the tds meter for larger pipe sizes.
Question by: Kenneth Burch on Jan 18, 2017 9:16:00 PM
Hey there, great question! You can connect this unit to multiple storage tanks without a problem! All you would need are the tee fittings and float valves for each tank. The auto shut off valve on the system is capable of handling multiple storage tanks. Unfortunately, we only carry the TDS meters in the 1/4" sizes.
Answer by: Randy (Admin) on Jan 20, 2017 10:41:00 AM
How many gallons goes to waste to make 1 gallon
Question by: Corey on Jan 18, 2017 9:43:00 PM
Awesome question! With the 150GPD system, the waste water to product water ratio is 2:1. For every 2 gallons of waste water you make 1 gallon of product water. :-)

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.

I bought the BRS 4 stage water saver plus . What water pressure is it best run at ?
Question by: jesse on May 19, 2016 12:33:00 PM
Answer by: Carter (Admin) on May 19, 2016 2:03:00 PM
Hi, can I use the RODI water as drinking water. Also, can I use the waste water for drinking water since it is already filtered although the first stages? I'm just really trying to avoid wasting water. Thanks!
Question by: Ryan on Dec 2, 2016 7:43:00 AM
Great question! It is not recommended to drink DI water. Over a period of time, the DI water can remove electrolytes and minerals from your body, as it tries to balance its ions. Also, it is NOT recommended to drink the waste water, as it is a highly concentrated blend of various metals, inorganic contaminates, biological and particulate contaminates, and organic contaminants.
Answer by: Randy (Admin) on Dec 2, 2016 9:32:00 AM

BRS 4 Stage Value Water Saver Plus RO/DI System Instructions

 Dow Filmtec Membrane BW60-1812-75


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. 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.


The Value Water Saver Plus is our most advanced model in the value series and includes a second RO membrane which doubles water production from 75 to 150 gallons per day, reduces waste water and effectively doubles pre filter life. All Plus models include a TDS meter and pressure gauge to monitor and ensure system performance as well as a flush kit to protect and prolong membrane performance.


4 Stages of Filtration:

  • Purtrex 1 Micron Depth Sediment Filter NSF Certified
  • BRS 1 Micron Universal Carbon Block (35,000 Gallons Chlorine / 3,500 Gallons Chloramines)
  • (2) 75 GPD Dow Filmtec Membranes NSF Certified
  • Pre-filled Single Deionization (DI) stage with refillable cartridge


Parts Bag Includes:

  • Filter wrench to tighten and loosen canisters
  • Chrome faucet connector with adapter rings to make a non-permanent connection to kitchen sink
  • Utility sink/garden hose adapter to make a non-permanent connection to garden hose or laundry tub
  • Insta-Test Free & Total Chlorine Strips to test water for proper filter replacement


Standard Features:

  • Automatic shut-off valve
  • Mur-lok Push Connect dual EPDM O-Ring fittings
  • 10 Ft Each of 1/4" Blue, Red and Black Tubing

  • Excellent unit! By Tylor on 3/27/2017

    The product works just like it says. It's quick and reliable. I have not had any problems since I have had the problem or any leaks
  • Unbeatable By Jim H. on 3/19/2017

    This unit screams quality and longevity. I added one more stage to make mine a total of 5. If you require pristine water for your tank(s) look no further.
  • Great By Chuck on 1/24/2017

    I bought this unit. Hooked it up and was only getting around 40 psi. After talking with customer service they recommended the pump for it. Hooked the pump up to the unit and had to turn the pressure down to 90 psi. Working great.
  • Brand new. I had to fix By Christopher on 1/3/2017

    I bought this system and hooked it up. I had a leak that most of the reviews have spoken about. I contacted customer service immediately. They were quick to respond however. They sent me the parts to fix. So think about this. You buy a product and have to fix it when it's brand new. Doesn't make much sense to me. Also, while fixing I found I had to take apart almost the entire system to fix the leaking part. If your not handy and don't want to buy a project, then I don't advise this system. If you don't mind extra work for your hard earned cash, then have at it. I did my research and came across the other reviews with the same issue. I figured those problems would have been so unlikel. What are the odds? Well I guess quite good. Be prepared to fix your brand new system if you purchase this one.
  • Good value By Chris on 12/6/2016

    I recently replaced an aging RO/DI system with this unit and couldn't be happier.

    I did have a leak when I first hooked the unit up...turned out one of the membrane canisters had a seal that was out of place. Once corrected everything has worked perfectly for the last 6+ months now.

    I am on a private ultimately I ended-up getting the booster pump for this...wish I would have done that sooner...the extra pressure really takes performance to whole new level!

    this company is the best great unit
  • Water saver By Brian on 11/18/2016

    This was an upgrade, from a 50gpd unit. So to step up to 150gpd is a big deal.

    The dual RO membrane really does reduce your rejection water. My 50 GPD unit would discharge 4-5 gallons of rejection for every 1 gallon of good water.
    With this unit I get 1- 1.5 gallons of discharge per 1 gallons of good water.

    Aside from this units gallons per day rating and it water saving capability, this is a very well made unit, and I felt good about buying it from BRS seems like they would stand behind it and seems like they have a better selection of higher quality filter refills than some of the other retailers out there. Yes I did some shopping around for this.
  • Great unit By Chris on 11/4/2016

    I've had this system for a little over a year now and it has preformed great. I couldn't even tell you how many thousands of gallons of ro water it produced for me. It's a pretty simple set up and the filters are so easy to change and it literally takes 30 seconds. Only problem I had since day 1 was a small trickle leak from one of the factory connections. It not really a huge issue and I usually just set the unit on a towel and it's fine but it still an issue... overall I think it's a fantastic unit and would definitely recommend to anyone in the market for a rodi system that used quality parts and easy to change filters
  • Saves so much water with time By Mr. Face on 10/25/2016

    Product speaks for itself first let me just say my tote fills within a couple hours and it's a 40 gallon. My last coral life ro unit tool over 24 hours with a nice smile happy face from the water department thanking me for the payment. Now after I got this water saver unit all I get in the mail from the water department is just only bill, no more smiley face so yes I would highly recommend this product to all. BTW my tank is 80 gal. 18 mag 160 diablo skimmer 2 reactor carbon and gfo uv unit mangrooves and a 30 breeder for sump.
  • Excellent By John on 10/16/2016

    I cannot recall the last time receiving any product mounted to a metal frame with such a solid and quality feel. It is easy to make something look good, but IMO it is the tactile quality that cannot be cheated. Awesome.
  • Just buy it By Anthony on 10/3/2016

    I started with the 75gpd model, and quickly upgraded to this. The unit is fantastic. RO/DI water is now easy, as is changing filters and maintenance on the unit. Great quality for reasonable price.
  • 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.
