All BRS Reverse Osmosis Systems have the appropriate flow restrictor installed.
The 75 and 100GPD flow restrictors are barrel models. The 150GPD is a capillary flow restrictor, which is the stem style that goes inside of your RO units waste water line, and can be trimmed if desired for optimal results.
|Restrictor||Restrictor Style||Suggested RO Membrane|
|200 mL||Barrel||20-30 GPD|
|300 mL||Barrel||30-40 GPD|
|350 mL||Barrel||40-55 GPD|
|550 mL||Barrel||55-75 GPD|
|800 mL||Barrel||75-100 GPD|
|800 mL||Capilary||100-150 GPD|
Worked perfect By BH on 12/18/2015BH would recommend this product to a friendI purchased this with the 150 gpd upgrade kit. Installed in seconds and worked perfect.
Works good! By Clockman on 2/4/2015Clockman would recommend this product to a friendGot this with the 75 gpd membrane and I must say I am a happy camper.
A Must Have if you upgrade your membrane By david on 9/25/2014david would recommend this product to a friendQuite simple. If you upgrade your membrane, you must have the correct size flow restrictor.
The opening on the 150 is very small. I suggest blowing through the hose to see if air makes it all the way through. if not, it is clogged.
Easy to install By Tom F on 5/5/2014Tom F would recommend this product to a friendEasily installed this and a 75 gallon per day filmtec membrane to upgrade my 35 gallon per day rodi to a 75 gallon per day rodi. Still probably need more for 210 gallon tank.
Works great and necessary! By Steve on 3/28/2014Steve would recommend this product to a friendIt took me a while, along with BRS support staff, to figure out my auto top-off wasn't working because my Coralife RO/DI did not have one of these!

Ask a question
If you have 75gpd membranes then the 550 would be the correct flow restrictor :)
As long as you change the flow restrictor to the 100gpd to match your 100gpd unit, you can run the 100gpd membrane.
If you were to find another 50 GPD membrane you will not need to change the flow restrictor. The same flow restrictor will be used on the single waste water line coming out of the second membrane. Feel free to let us know if you have any further questions!
It goes on the waste water line out of the membrane.
The flow restrictor always goes on the waste water line. They come in a few different varieties including some that are on the inside of the tubing. Your unit likely wouldn't have worked without one so pretty good bet its hiding there somewhere.
No you should not. You want to keep your existing 75gpd flow restrictor :-)
