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

 

Installation Note: Aquatec 8800 Pressure Switch & Aquatec 8800 Power Supply required for installtion.

 

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.

Product Questions

Which is the proper unit to use with two 75 gpd membranes (the 150 gpd upgrade)?
Question by: Justin on Jan 19, 2020, 6:29 AM
Hey there!

You are looking for the 500ml/Min flow restrictor.

Take care
Answer by: Thomas Billington on Jan 22, 2020, 2:34 PM
Does this come packaged with the power supply and pressure switch? If not, where can I find them?
Question by: Kyle on May 7, 2016, 1:26 PM
Great question,
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?
Question by: Dell on May 15, 2017, 3:57 PM
Hey there,
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?
Question by: Scott on Mar 17, 2016, 8:56 AM
Great question!
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!
Answer by: Connor on Mar 18, 2016, 9:31 AM
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.
Question by: Antonio on May 27, 2017, 9:51 PM
This unit may not be of very much benefit to you for those purposes. The auto flush is designed to run every hour during operation, but the unit may not run for that long when only topping up.

Have a great day!
Answer by: Zack on Jun 5, 2017, 3:12 PM
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?
Question by: Brian on Nov 17, 2016, 3:10 PM
Great question! Yes you will still need the auto shut off valve for your unit. The auto shut off will shut off the waste water and the product water. Without that back pressure, the auto flush will continuously run, wasting your water down the drain. :-)

Can I use the 600ml/min auto flush flow restrictor for two 75 gpd membranes(150 gpd upgrade) ?
Question by: Reginald L Singco on Mar 31, 2020, 7:15 PM
Hi there,

For two 75 GPD we would recommend the 500ml/min over the 600ml/min.

Take care
Answer by: Thomas Billington on Apr 2, 2020, 10:57 AM
My household water pressure is between 55 and 60 psi. Would I need a booster pump with the auto flush?
Question by: David Howard on May 11, 2016, 12:58 AM
Great question!
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.
Answer by: Connor on May 11, 2016, 6:23 PM
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!
Question by: Tyler on Nov 25, 2016, 8:05 PM
Great question! The 150GPD water saver includes two 75gpd membranes. You will need the 500mL restrictor for those. :-)
Answer by: Randy on Nov 26, 2016, 9:15 AM
Which auto flush should I purchase for a RODI system using the 150 GPD membrane and an 8800 booster pump?
Question by: Art on Oct 19, 2013, 2:37 PM
Hi Art,
For a unit with a 150gpd membrane/flow restrictor you would want the 800mL auto flush.
Answer by: Bulk Reef Supply on Oct 19, 2013, 2:37 PM
Can an autoflush be used with a permeate pump? Thanks!
Question by: Rush on Jun 8, 2016, 5:36 PM
Certainly can be used with either no pump or just a permeate pump. Only item you will need is the pressure switch, auto flush and power supply by Aquatec. Feel free to let us know if you have any further questions!
Answer by: Connor on Jun 8, 2016, 5:51 PM
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?
Question by: Derek on Oct 29, 2017, 1:58 AM
That is a really good question, and the capillary style of flow restrictors can actually be trimmed and fine-tuned to your homes water pressure and temperature for the membrane you are using so they come in a higher rating to restrict more water. When you trim the capillary restrictors, stem you are lowering its restriction capability and allowing more water through the restrictor. That is why you usually see flow restrictors like the inline (barrel) type or the Auto Flush Valves for the same membrane have a lower mL/min rating since they are designed to be “pre-tuned” for all styles of membranes at that GPD rating. Ultimately the capillary style can yield the best results for waste:product water but in most cases using an Auto Flush Valve or an inline style works just fine and the difference is negligible.

hi
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?
Question by: Mike on Jan 27, 2017, 2:05 AM
Great question! The pressure switch is required with this system, as it does not have a pressure sensor built in. Without the pressure switch it would continually flush, adding more stress to the auto flush and wasting water. The pressure switch will electronically shut off the auto flush when the back pressure reaches 40psi. :-)
Answer by: Randy on Jan 29, 2017, 8:09 PM
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?)
Question by: Kyle on Mar 24, 2017, 9:49 AM
Hey there,
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!
Answer by: Zack on Mar 30, 2017, 2:15 PM
Can you please recommend an auto flush flow restrictor for my drinking water system. It's a 75gpd system with a booster pump providing 80psi supply. There is also a permeate pump. Thanks.
Question by: Jerome Llerandi on May 20, 2022, 3:24 PM
/Hey there,
Thank you for reaching out to us. For a 75 GPD system, you will want the 500 mL unit.

Please let me know if you need anything further and take care!
Answer by: Matt Lucero (BRS Staff) on May 23, 2022, 9:42 AM
Is it possible to get a 200 mL/min version or am I out of luck? I'm using a Pentair GRO-75EN Membrane. It is a high-efficiency membrane and it requires a 200 mL/min flow restrictor in order to achieve their advertised 50% recovery rate (1:1 rejection ratio). Their 50 gpd model (GRO-50EN) uses a 150 mL/min flow restrictor.
Question by: John G. on Nov 15, 2021, 3:59 PM
Hello, we only carry the: 75 GPD Auto Flush Flow Kit 500ml/min Auto Flush Flow Restrictor. and the 100 GPD Auto Flush Flow Kit 800ml/min Auto Flush Flow Restrictor. Thank you.
Answer by: Christian Jimenez (BRS Staff) on Nov 15, 2021, 4:27 PM
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.
Question by: Ryan on Jan 12, 2017, 9:55 AM
Great question! For that system you will need the 800 mL/min Auto Flush Flow Restrictor. :-)
Answer by: Randy on Jan 12, 2017, 2:52 PM
What is the proper way to use this auto flush restrictor with two 75 gpd membranes (the 150 gpd upgrade)?
Question by: Josh on Jan 13, 2014, 2:57 PM
-2
Hi Josh,
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.
Answer by: Bulk Reef Supply on Jan 13, 2014, 2:57 PM
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?
Question by: Michael on Dec 10, 2013, 4:47 AM
-3
Hey Michael,
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.
