Quick Overview

Why does BRS recommend this?


The 150 GPD water saving upgrade kit is probably our most favorite RODI upgrade.  If you have proper pressure (65+ PSI) we highly recommend installing the kit, because it will produce water twice as fast as a standard 75 GPD membrane while cutting the amount of waste water in in half.


The BRS 150 GPD Water Saver Upgrade Kit increases the production of any BRS 75 GPD reverse osmosis system to 150 GPD while cutting waste water by 50%. With the installation of this kit water production will increase water production from approximately three gallons per hour to six.

yes hi im not sure if my question is worth asking or not but i was just wondering if it would be better or defeating the purpose of the water saver RO add on.......wondering if it would be better to split the water line going into the first RO so it goes into both RO units then each have there own waste water discharge ? im just concerned that the waste water coming out of the add on RO unit and going into the second one is all bad water which to me seems like its going to make the second RO go bad a lot faster then the first? and also whats the best PSI to run the unit with the water saver add on, 65psi or is there a more optimum PSI and 65 psi is just the minimum? i get well over 150 psi coming out of my tap.
Question by: Tony on Mar 3, 2014 6:50:00 PM
Hi Tony,
If you split the incoming water going going into the membranes then you basically just have two RO/DI units and would have double the amount of waste water. In that situation it would actually just be better to swap it out for a single 150gpd membrane because you would have lower replacement costs in the future.

Keep in mind that while the waste water feeding the second membrane is higher in TDS then the first membrane, because of the waste water ratio its really not that much of a difference. If for example you had 100TDS going into the first membrane, the waste water coming out and going into the second membrane would likely be around 120-130tds. Assuming the membranes get there normal 98% rejection rate, that means the first membrane would produce water at 2 tds and the second membrane would produce water at 2.6 tds (so the average total tds being 2.3. As you can see, not much of a difference.

The reason we only suggest this unit for systems with relativly low TDS to begin with though is that this effect is amplified the higher the TDS, at 500 tds your actually getting into the range of a few TDS instead of fractions of a single TDS, though even at 500 TDS your looking at 10 out of the first membrane, ~12 out of the second for an average of 11 (and a difference of 1).

RO membranes run better at higher pressures though you shouldn't exceed the 80psi maximum on the unit itself. I would double check the number on the incoming water pressure though as the 150 might have been a different unit of measurement then PSI. Its certainly not impossible to see numbers that high in some areas but 150psi is into exploding pex, toilet, refrigerator, and washing machine territory :-) In fact I think plumbing code in most places is 80psi maximum or your required to have a pressure regulator (may be different in your area though).

I have a 100 gpd RO/DI unit. I want to use the upgrade kit which is only for 75 gpd units. If I order the kit and purchase a separate membrane that has a rating of 100 gpd to go inside the casing, would this work? Also, would I need to flush the new membrane for one hour like I did for the original installation?
Thanks so much,
Shara Armstrong
Question by: Shara Armstrong on Jan 26, 2016 11:31:00 AM
Great question!
You would need the kit plus the 100 GPD membrane. in addition the flow restrictor from your current units waste line will need to be moved to the waste water of the second membrane. The new membrane will need to be flushed as with the original. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 3, 2016 1:31:00 PM
Will the 150 GPD water saver work with a 50 GPH RO system? I'm assuming if it does that it would bring the output down to 125 GPD.
Thanks.
Question by: Jeff on Jul 10, 2014 7:17:00 AM
Hey Jeff,
Unfortunately it would not. The membranes need to be the same size otherwise the flow restrictor would be mismatched to one membrane or the other.
Answer by: Bulk Reef Supply on Jul 10, 2014 7:17:00 AM
Sir, I have a 100 gallon per day system Am I able to use the 150g per day water saver upgrade kit on it? It says in the overview its for a system that is 75gallons per day. so I wasnt sure. If so how many gallons a day would it be.
Thanks George

Question by: George on Jul 10, 2014 8:57:00 AM
Hi George,
Unfortunately it has to be a 75gpd system because the membranes have to match. If used with a different sized membrane the flow restrictor would be a mismatch to one membrane or the other.

Hi, BRS
I'm sold on the need for this RO upgrade kit for my BRS 75 gal RO DI filter but my hesitation comes from plumbing in my membrane flush kit. I think I understand how membrane flush kit will be plumbed in, though not real clear on it. None of the videos seem to address this. Can you explain the hook-up for me? Thanks!
Question by: Bob on Jul 11, 2014 4:36:00 AM
Hi Bob,
When you install the kit you move the whole waste water assembly to the new membrane housing. The flush kit and flow restrictor go along with the tube. If you have a flush kit it will continue to work and will flush both membranes. As far as installation goes, just follow the instructions as if it isn't there, it doesn't change the process any :)
Answer by: Bulk Reef Supply on Jul 11, 2014 4:36:00 AM
The pressure gauge on my 5 stage plus reads between 60-70psi (varies based on time of day, and apparently, ambient temperature..go figure).

Anyway, is that gauge before or after the first membrane? I'm trying to figure out if I'll need to get a booster pump with this.
Question by: Dariush on Jul 21, 2014 5:14:00 AM
Hi Dariush,
That is the acting pressure on the membrane (which will be the same between the last carbon block and the flow restrictor). No bosoter pump is needed :)

My RO/DI unit has the membrane flush kit. will I have to remove that to install the upgrade?
Question by: Josh on Jul 30, 2014 4:28:00 PM
Hi Josh,
You will not have to remove it. You will just move it like you would the flow restrictor on a normal unit and then it will function to flush both membranes.
Answer by: Bulk Reef Supply on Jul 30, 2014 4:28:00 PM
I'm really interested in this but this is what I've got. Tds out of tap is 380. Water psi is 57. Is there such a thing as a pre-filter before my ro/di? Am I going to need a booster pump togain 3 psi for this? Thanks
Question by: Shaun on Aug 1, 2014 4:47:00 PM
Hi Shaun,
No booster pump would be necessary here. The only real concern would be the TDS levels. With the TDS that high you may see a noticeable difference in the rate of DI consumption after adding the unit. You will still get 0 TDS water out of the DI resin though, it just won't last as long.
Answer by: Bulk Reef Supply on Aug 1, 2014 4:47:00 PM
Hi, is this the upgrade kit for BRS 5 Stage RO/DI System - 75GPD which I purchased before. And is it really can cut down the amount of waste water by 50% as I have watched the video by Mr. Saltwater Tank??
Question by: Evan on Mar 22, 2014 11:04:00 AM
Hi Evan,
That is true. Assuming you have enough water pressure (65psi) and water temp, the kit would allow you to produce twice as much product water for the same amount of waste water (ie, cut your waste water in half).
Answer by: Bulk Reef Supply on Mar 22, 2014 11:04:00 AM
the install video dose not seem to be working. Can you send me some instruction on how to install this upgrade.
Thank you
Question by: Mike on Jun 9, 2014 8:38:00 AM
Hey Mike,
Does this link to the installation video work for you?

Video is really the easiest way to do this but if your computer does not have the ability to play YouTube video's just let us know and we will get you figured out.

Will the membrane flush kit effectively flush both membranes when used with this upgrade? Also is it still possible to use a DI bypass valve?
Question by: Mark P on Jan 13, 2014 3:02:00 AM
Hi Mark,
It sure would. It also wouldn't make any difference to whether you choose to bypass the DI (or just disconnect the DI altogether).

I have the BRS 5 STAGE PLUS RO/DI SYSTEM - 75GPD, will I need another flush kit if I do this upgrade?
Question by: Jason on Mar 21, 2014 2:37:00 PM
Hi Jason,
Fortunately you will not. Both membranes operate off the same flow restrictor and thus only the existing flush kit is needed.
Answer by: Bulk Reef Supply on Mar 21, 2014 2:37:00 PM
Hi,
Does this kit come with a flow restrictor?
If not would I need the 75 gpd or the 150 gpd flow restrictor.
Thanks
Glenn
Question by: Glenn on Nov 11, 2013 8:42:00 AM
Hi Glenn,
It does not but you actually don't want to switch your floor restrictor. You want to stick with the same 75gpd restrictor you have.
Answer by: Bulk Reef Supply on Nov 11, 2013 8:42:00 AM
I was wondering which is better for water quality and less waste water, the 150gpd upgrade kit, or the 150gpd membrane by itself? Also, if I add the auto flushing valve, do I use the one for a 150gpd membrane, or the one for 75gpd membrane on this kit? Thank you.
Question by: Paul on Oct 1, 2013 6:43:00 PM
Hey Paul,
It depends on what your main goal is. The 150gpd upgrade kit is better for waste water but will technically create slightly worse quality of water (though unless you have very high TDS to begin with it would be unmeasurable difference to most). If you do have high TDS though we wouldn't recommend the 150gpd upgrade kit.

For an auto flush valve/flow restrictor you would want the proper size for the membrane(s). If you use the 150gpd membrane you want the 150gpd size, if you are using 75gpd membrane(s) then you would want the the 75gpd size.

Could I use this for my 5 stage deluxe, with the drinking add on? I use my 5 stage for both my reef tank and to supply water to my fridge.
Question by: Derrick on Oct 20, 2013 8:22:00 AM
Hey Derrick,
With the drinking water add-on you will have a lot more back pressure which would make the dual system a lot less efficient. If your goal is to reduce waste water you would likely be better served by a permeate pump. The permeate pump uses the pressure from your waste water to reduce the effect of the storage tanks back pressure. This will make your existing membrane more efficient and allow you to get more pressure in the tank as well. Its compatible with systems up to 100gpd.

I have the BRS 5 STAGE PLUS RO/DI SYSTEM - 75GPD My water pressure gauge is reading 43lbs, In your viedo you say that i need 65 lbs going in to the unit . Was wondering if the 43 lbs is enough pressure for the BRS 150 GPD Water Saver Upgrade Kit to work. I am not really sure where the gauge is at on the BRS 5 STAGE PLUS RO/DI SYSTEM - 75GPD I am guessing that it is after all the membranes to be able to tell when they need change. Can you please let me know if you think this will work or will I have to get a booster pump? Thank You Michael
Question by: Michael on Oct 2, 2013 4:26:00 PM
Hi Michael,
The 150gpd water saving upgrade kit requires 65psi. If your unit only has 43psi then you would need to increase the pressure to 65psi to add the kit so a booster pump would be necessary.
Answer by: Bulk Reef Supply on Oct 2, 2013 4:26:00 PM
I've read that if you cut down you waste water you will blows thigh RO filters as well as DI filter faster. If there any truth to this? I live the speed and my last water is so much lower. Just not sure I want to blow though the filters if there is any truth to this..

Robb
Question by: Robb and Trudi on Sep 17, 2013 11:55:00 AM
Hey Robb,
Its true that artificially restricting the amount of waste water (which is really flush water) a membrane receives will likely reduce the membrane lifespan and increase the TDS of the out-coming water which will decrease the lifespan of the DI resin as well, though it shouldn't have any sort of negative effect on the prefilters themselves.

Its important to note that this is NOT how the 150gpd upgrade kit works though. The 150gpd upgrade kit adds a second membrane to reprocess the waste water of the first membrane. With the kit each membrane actually continues to get the minimum amount of flush water (actually one of them even gets extra flush water).

  • Should have bought this at the beginning By dmolavi on 2/2/2016

    I got tired of waiting for almost 2 hrs for 3 gallons to be made. This cut it down to almost 45 minutes. I can't recommend this highly enough.
  • Just read! By Sam on 2/1/2016

    I wish I had just bought the 150gpd from the start. I didn't realize how slow 75 a day was.. It took hours to fill a 5 gallon jug. Thankfully since I didn't do it from the start this upgrade exists!
  • Get it now! By jsbull on 1/2/2016

    This thing is awesome. Easy to put together after watching their video and works wonderfully.
  • A Really great Product By 2manyhobbies on 12/27/2015

    I watched the video on BRS TV and followed their instructions. It all snapped together perfectly and I am now producing water in half the time. The best thing to come along in quite a while.
  • Great product addition! By JR on 12/21/2015

    I am on a well with low pressure so I added a booster pump and with this recently purchased additional RO section I am getting about 10 gal per hour at 0 TDS. Input TDS is only about 20 max, my waste is very low and the resin is lasting much longer. Well worth the money.
  • Wow!!! By Jay on 12/19/2015

    I'm getting about 1:1 ratio now of product to waste water and I am completely satisfied with another awesome BRS product. I watched the BRS video about this upgrade kit a couple times and installation was a breeze. I lucked out and get about 90 psi from the outside faucet I use for my ro/di reef tank water. So no booster pump necessary, but I wouldn't hesitate to get a booster pump from BRS if it was needed especially with the 1:1 production that results. Thanks BRS!!!
  • A+ By BH on 12/18/2015

    I can only echo what everyone else has said; if you do your own RO/DI water it doesn't make sense not to buy this. In only two months I will save on my water bill what this upgrade cost. In my opinion, it is one of the few things in the reef keeping world where you get a monetary return on your investment. As many others have said, I wish I had purchased this long ago.
  • A+++++++++++ By Chuck on 12/11/2015

    I had a 4 stage 75 GPH . with 6 stage up grade and up grade GPH to 150. All I can say is I wish I would of did this from the start. Way more water pressure even.
  • Easy install, instant results. By Diving The World on 12/11/2015

    The installation was fairly strait foward. I noticed an immediate drop in waste water and increase in production.
  • Makes water fast By Ray on 10/19/2015

    Added the 150gpd upgrade to my BRS 6 stage RODI. I was already running a booster pump due to low supply pressure. After installing the kit I am making nearly 190gpd of 2TDS water off of the membrane (zero after first DI stage) at a 1:1 product : waste ratio. This will decrease the need to replace profilers in addition to filling my 30 gallon storage tank in no time. Great upgrade.
  • Great Product By Jonathan on 9/27/2015

    This greatly increased the speed of my RODI unit. The only con is that it doesn't come with install instructions and instead you have to go to their channel to find the how to video. That being said, the video is really easy to understand and I absolutely love the channel.
  • Amazing, best possible purchase By Pvpd106 on 9/2/2015

    If you have a RO/DI system this item is a must. My production doubled and waste was cut in half. This thing pays for itself in no time from the savings on your water bill. More RO/DI less waste = $avings.
