- Reverse Osmosis Flow Restrictor
Flow restrictors are essential to a properly functioning RO system. Be sure to have the appropriate flow restrictor for the membrane you have. If you decide to change your membrane to a higher or lower GPD membrane, you must also replace the flow restrictor to correspond with the membrane.
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!

System upgrade By Manfred on 2/17/2014Manfred would recommend this product to a friendBought the 75 gallon flow restrictor and membrane and my water production went up to over 3 gallons per hour from a little over a gallon per hour. YEA!
Easy instal works great By Redneck reefer on 1/23/2014Redneck reefer would recommend this product to a friendBought with membrane upgrade installs easy and works great
Top quality By Redneck reefer on 1/23/2014Redneck reefer would recommend this product to a friendBought with membrane upgrade easy install and works great
Excellent Product By STEVEN on 4/3/2013STEVEN would recommend this product to a friendThis was purchased along with an upgraded membrane. Product was installed within seconds and performed as it should. Very happy with BRS products.
75 GPD Flow Restrictor By Kenneth on 2/15/2013Kenneth would recommend this product to a friendupgraded RO unit from a 50 GPD membrane to a 75 GPD, plus added the BRS 150 GPD Water Saver Upgrade Kit
. This was easy to install and does not leak. Would recommend.
Works Great By Richard j on 10/10/2012Richard j would recommend this product to a friendBought this with the 75gph membrane. Works like a charm.
Today on BRStv, we have another episode of BRS 52 ...
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 :-)
