The Aquatec Auto-Flush Flow Restrictor features:
- Reduction in waste water ratio
- Increase in the TDS rejection rate
- Extended membrane life
- 1/4" hose push connections
- Hermetically protected electronics for long life
An Auto-Flush Flow Restrictor will assist the RO membrane to perform with maximum efficiency for longer time periods. At BRS, we recommend that an RO system be flushed on a regular basis. The use of this auto-flush flow restrictor can reduce the “brine to product” ratio, especially in low “TDS” applications, while maintaining or improving system “TDS” rejection rate and extending membrane sediment and carbon filter life.
Upon system start-up and every hour thereafter, the 24VAC normally closed solenoid valve automatically “power flushes” the membrane at full pump flow, or full line pressure in unboosted systems, for 18 seconds every hour. Turbulent water action scrubs organic and inorganic contaminant’s from the membrane surface, extending membrane life and efficiency.
The “power flush” system only occurs only while the system is in the water making mode. The flush cycle is reset automatically when the RO system repeats the “water making” mode after the “full tank shut-down” mode. Water which has been standing idle in the membrane module for extended period is purged to the drain.
The PFR requires its own transformer or can be powered by the pump transformer.The valve has a built in, self cleaning, flow restrictor which allows controlled flow to drain when the valve is in the de-activated (closed) state.
Works but needs some work By Ryan on 6/13/2018Ryan would recommend this product to a friendWas excited to finally get this and add it to my system because it was out of stock for quite a while. It does exactly what it suppose to do but it more than doubled my pre di TDS. From 2-3 after a flush skyrocket high for a min or so then to 7-5 for a long time then at the very end of a 30 gallon fill to 4. I love not having to be there for a flush because my system also runs a pressurized tank for ice/water in the fridge and a separate tap for the coffee maker. Before adding this though the water from the tank came out at 3 now it's 6. I used as close to the 550 that came with my system as I could get. My membranes should last longer but I'll pay it out and then some in resin unless I find another solution.
It works By Ryan on 1/24/2018Ryan would recommend this product to a friendOverall I'd recommend this to a friend as it surpasses any alternative but would mention a few things.
1- If using an electronic auto shutoff & pump you need to connect the power to the shutoff, then the flush and pump so that the shutoff kills power to all of them.
2- when the flow is flushing there is little to no noise, when it's on it hisses fairly loudly. This isn't all bad because you know it's running. However, I'm going to put some foam insulation around it to try and deaden the noise because it's loud.
Not sure By Mark on 3/7/2017Mark would recommend this product to a friendI wish it had a LED 'On' indicator or something to let you know it was working. I have a permeate pump in my system so you would think it should make its distinctive pumping noise if it was getting waste water from a flush, but it doesn't. My system is installed under my kitchen sink, so it's kinda hard to see what, if anything it's doing. I was sure I would be hearing water flow when it does it's routine maintenance flushes but no on that too.
A Must Have! By TonyP on 5/14/2016TonyP would recommend this product to a friendMakes life easy, prolongs the life of your RO/DI filters and improves the quality of your water output. It's one less thing to remember to do and is very easy to install.
One less thing to remember By Steve on 2/22/2016Steve would recommend this product to a friendInstalled the auto flush with the Aquatec 8800 Booster Pump. It was simple to install and the auto flush is excellent. It automatically flushes each time the pump turns on which has been great with the auto top off I have set up.
This is a "NO BRAINER" By Bob E on 12/31/2015Bob E would recommend this product to a friendI have run RO/DI for over 10 years. 100 GPD on the current one. I Have low TDS of 102 -110 and reasonable priced city water. I had an 800 size orifice on the system as that was what was recommended when I built my customized RO/DI system. So it was black Friday and BRS had these on sale, time to pull the trigger. I bought a new membrane as the current one was at 7 tds now but was at 2 when I installed it. I ordered the 600 orifice as I thought the flusher would help keep new membrane clean over the long haul and my water is very clean city water. So when I got the flush kit, I hooked it up before replacing membrane and a little over a month later, my TDS is between 1 & 2. The smaller orifice is saving me water and the flusher is going to make my membrane & DI resin last longer.
Plus the first minute of dirty water is flushed in stead of put in my ATO tank. I evaporate at least 4 gallons a day(depends on how long cooling fans run on tank), and do water changes of 45 gallon weekly(?). The mix tank fills at least 1 hr quicker than it did. I have 2 inline TDS readers on my system. 1 meter reads water into unit and the other reads water out of the membrane. The second meter shows water out of membrane and then after DI resin. So I can read membrane with 2 different inline testers and they both read the same. So these are accurate readings. This will pay for itself in less than a year. I have been putting off buying one for a couple of years, and now I wish I would have sooner, even at normal price. Go ahead, start saving money now you won't regret it, especially if you make a lot of RO water.
Works like a champ By MICHAEL on 11/14/2015MICHAEL would recommend this product to a friendMakes it a lot easier than Manual flush
Awesome By Dan on 3/21/2015Dan would recommend this product to a friendLove that it automatically flushes and I can forget about it.
SAVES LIFE OF MEMBRAINE
Does what it should By StarFishMan on 2/27/2015StarFishMan would recommend this product to a friendThis is just the ticket. Easy to install just pay attention to the in and out arrows on the device. Painless and it does exactly what is should. This coupled with the booster pump, float, and pressure switch for me are working exactly as I hoped they would. One happy camper.
Great add on By Jose on 1/19/2015Jose would recommend this product to a friendThis is a great add on to r/o save makes it easy
Very useful addition to my RO system By Chuck413 on 1/11/2015Chuck413 would recommend this product to a friendI am using my RO system to clean some brackish well water. The RO membrane needs to be flushed regularly to maintain its performance. This device does just that. It provides unrestricted flow for 25 seconds every hour keeping the membrane functioning well under these challenging conditions. I just wish I could adjust the interval between flushes.
works great By John on 8/22/2014John would recommend this product to a friendMakes life easier i have my system set up for both my reef and drinking water. Great add on for any RO system

Does this come packaged with the power supply and pressure switch? If not, where can I find them?
This will not come with the power supply and pressure switch. They can be found in the link below or by searching aquatec in the search bar.
Just wondering if this item comes with the wire harness or must it be purchased separate?
The wire harness is included, but the power supply is sold separately. This unit will require the booster pump kit or power supply in order to function with your RODI.
Have a great day!
My home's water pressure is around 95psi. I want to install the auto flush flow restrict or to my BRS 150 GPD 6 stage system. Will I need the booster pump still? Or just the power supply?
You will not need the booster pump, just the Auto Flush and the power supply. Feel free to let us know if you have any further questions!
My RO system is a drinking water system (used several times a day) and used to make DI water for aquarium also. Would you recommend an auto flush for this application? Seems like it might not be a good idea if the auto flush will be flushing everytime I get a glass of RO to drink. Thanks.
Have a great day!
Do I need to use an auto shutoff valve if I have this on my system? If I don't will this flow restrict or constantly drain water when my booster pump is off but we'll pressure is still on the system?
My household water pressure is between 55 and 60 psi. Would I need a booster pump with the auto flush?
the booster pump will not be required with your pressure. To use the auto flush you can use just the pressure switch, power supply and auto flush.
Picking out the parts I need for this to work seems a little confusing. I just purchased the BRS 150 GPD water saver plus. My source water has somewhere between 153 and 223 TDS at 65 PSI or higher (80PSI currently). Does this mean I should get the 500mL/min restrictor? Also, does it flush the membrane at the end of water production as well, or just the beginning and every hour? Thanks!
Which auto flush should I purchase for a RODI system using the 150 GPD membrane and an 8800 booster pump?
For a unit with a 150gpd membrane/flow restrictor you would want the 800mL auto flush.
Can an autoflush be used with a permeate pump? Thanks!
Hey guys, quick question. I am running a dual 100gpd membrane RO setup. According to the capillary tube selections, an 800mL/Min is recommended. But looking at these auto flush valves, 75pgd uses the 500mL and the 150gpd single membrane uses the 800mL. Since the 100gpd is 1/3 between the two, would the 600mL be the correct piece to the puzzle for my installation?
i have a genesis renew storm system that monitors the ro/di bin for water level (low and high) once low it send power to a solenoid which opens and sends tap water to BRS delux 6 stage ro/di unit. at 65 psi. once high level sensor in bin is triggered system shuts down the power thus putting the solenoid in closed mode, knowing that i will place this auto flush and the transformer on the same line that powers the main solenoid thus water supply from tap and auto flush kit will both power up and shut down at same time... will this setup still require a pressure switch?
When the auto flush is active, is the water diverted through the waste water, and no "product" water being produced? (I.e.. the water that is flushing the membrane is not ending up in my collection tank?)
During the flush cycle, the water is allowed to rush over the membrane and then bypass the flow restrictor and go down the drain, rather than being forced through the membrane. As a result, during this flush cycle, flow through the product line will significantly slow or cease altogether.
Have a great day!
I have your 300gpd spartan unit. What version of this would I need? My reds coming into the unit is pretty low only around 50tds if that makes any difference. Thanks.
What is the proper way to use this auto flush restrictor with two 75 gpd membranes (the 150 gpd upgrade)?
This would instal in place of your existing 75gpd flow restrictor on a setup like that. Use and setup would be no different then setting it up with any other RO/DI unit and booster pump combo.
Would you need to remove the entire membrane flush kit I have installed currently to install this auto flush or would I just leave it and replace the flow restrictor?
Most folks would remove it as its a bit redundant though it technically wouldn't hurt anything to leave it and just leave the valve closed.
