night and day difference, great kit By Dave on 12/16/2014Dave would recommend this product to a friendGreat kit. Amazed at how much faster I can make RODI water. There is a significant reduction in waste water. I did have to buy the booster pump, but we'll worth it.
EASY AND WORTHWHILE By Claude on 12/15/2014Claude would recommend this product to a friendThis kits was very easy and quick to install. Took me about 3 minutes to install and doubled the output of my system. Great upgrade.
water saver By Michael on 12/13/2014Michael would recommend this product to a friendThis add on kit is a good investment coupled with a booster pump. doubled my water output, and the di resin usage is also lowered. could come with hookup direction, but that what brs is for
great upgrade By mike on 12/13/2014mike would recommend this product to a friendI bought this hoping it would double my ro output, and did it ever. very easy to hookup and now it only takes me five hours to make 40 gallons of rodi water instead of twenty hours. well worth the buy. would strongly recommend a booster pump to go along with it.
No brainer By Arrick on 11/21/2014Arrick would recommend this product to a friendThis is easily one of the best investments I've made for my tank. Honestly should have purchased a long time ago.
Highly recommend this product By Don on 11/17/2014Don would recommend this product to a friendSet up was easy, just follow the BRS video on-line, took less than 10 minutes.
This addition to your system really increases the amount of RO/DI water produced in much less time. It also decreases the amount of waste water produced.
I did have to use a booster pump from an old unit that I was replacing with this one because my water pressure was less than 60.
Very good addition By Vincent on 11/17/2014Vincent would recommend this product to a friendMore than doubled my output. Saves water also.
Worth every penny By Glenn on 11/13/2014Glenn would recommend this product to a friendMy pressure runs at 80 psi and was still taking forever to fill my water storage tanks. This fills up my two 45 gallon bins MUCH faster. I used to start it up and forget about it. Now I worry about it filing too fast and overflowing if I forget to shut it off before leaving the house!
Easy to set up By shdw2001h on 10/27/2014shdw2001h would recommend this product to a friendI purchased this system recently and found it very easy to set up following the video they have on the site. as far as saving water I have not had it long enough to see if it is saving water.
Water saver upgrade kit By Dat on 10/24/2014Dat would recommend this product to a friendI purchased this upgrade to my 75 BRS RODI and drinking water system. It works great cut down the time to 45 minutes for five gallons of water rather than 1:15 minutes. It didn't come with instruction, so looked it up at Bulk Reef website. The video show how to installed on a basic Ro system only. So it took me time to figure out how to installed it on my RODI and drinking water system.
Great idea By Ralph on 10/15/2014Ralph would recommend this product to a friendWith the drought I decided to cut the wasted water that was going down the drain. This was a no brainer for that one. It has cut the waste while cutting the water bill. The video walked me through the install. In just a few minutes it was installed without any problems at all. Great idea and Great products.
Saves time and money By Greg on 10/11/2014Greg would recommend this product to a friendDoubled my water.. Saves time and money... I also purchased the dual cannister DI system.. Works great together

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.
Bulk Reef Supply 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.
by Glenn on November 11, 2013, @8:42 AM
Does this kit come with a flow restrictor?
If not would I need the 75 gpd or the 150 gpd flow restrictor.
Bulk Reef Supply 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.

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
Bulk Reef Supply 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.

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..
Bulk Reef Supply 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).

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.
Bulk Reef Supply 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 the BRS 5 STAGE PLUS RO/DI SYSTEM - 75GPD, will I need another flush kit if I do this upgrade?
Bulk Reef Supply Hi Jason,
Fortunately you will not. Both membranes operate off the same flow restrictor and thus only the existing flush kit is needed.
by Derrick on October 20, 2013, @8:22 AM
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.
Bulk Reef Supply 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.
by Mark P on January 13, 2014, @3:02 AM
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?
Bulk Reef Supply 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).
The BRS 150 GPD Water Saver Upgrade Kit will also work with different brand 75 GPD reverse osmosis systems. The kit requires 65psi into the first membrane in order to function properly. If your home's water pressure is less then the recommended psi a booster pump will be necessary.
If you are purchasing a reverse osmosis unit from us at the same time as this 150 GPD Upgrade Kit please mention in your order comments if you would like us to install the unit for you. If you select this option, there may be a one day delay in shipping your order due to additional time considerations. 150GPD water saving upgrade kit is not recommended for units with high TDS or drinking water systems
