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 1:26:00 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 3:57:00 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 8:56:00 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 (Admin) on Mar 18, 2016 9:31:00 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 9:51:00 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 (Admin) on Jun 5, 2017 3:12:00 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 3:10:00 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. :-)

Answer by: Randy (Admin) on Nov 18, 2016 8:43:00 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 12:58:00 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 (Admin) on May 11, 2016 6:23:00 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 8:05:00 PM
Great question! The 150GPD water saver includes two 75gpd membranes. You will need the 500mL restrictor for those. :-)
Answer by: Randy (Admin) on Nov 26, 2016 9:15:00 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 2:37:00 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 2:37:00 PM
Can an autoflush be used with a permeate pump? Thanks!
Question by: Rush on Jun 8, 2016 5:36:00 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 (Admin) on Jun 8, 2016 5:51:00 PM
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 2:05:00 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 (Admin) on Jan 29, 2017 8:09:00 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 9:49:00 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 (Admin) on Mar 30, 2017 2:15:00 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 9:55:00 AM
Great question! For that system you will need the 800 mL/min Auto Flush Flow Restrictor. :-)
Answer by: Randy (Admin) on Jan 12, 2017 2:52:00 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 2:57:00 PM
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 2:57:00 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 4:47:00 AM
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.

Full Details

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.

  • Not sure By Mark on 3/7/2017

    I 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 5/14/2016

    Makes 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 2/22/2016

    Installed 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 12/31/2015

    I 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 11/14/2015

    Makes it a lot easier than Manual flush
  • Awesome By Dan on 3/21/2015

    Love that it automatically flushes and I can forget about it.
    SAVES LIFE OF MEMBRAINE
  • Does what it should By StarFishMan on 2/27/2015

    This 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 1/19/2015

    This is a great add on to r/o save makes it easy
  • Very useful addition to my RO system By Chuck413 on 1/11/2015

    I 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 8/22/2014

    Makes life easier i have my system set up for both my reef and drinking water. Great add on for any RO system
  • Just makes life a litle easier By Brian on 1/28/2014

    Not much to say, it does what it's supposed to. It came with no instructions on how to install, and as of yet there is no video on how to hook it up (HINT, HINT). There’s not much to installing it but I did make the mistake of thinking that it was to replace my manual back flush valve, not replace the whole back flush assembly entirely. Another words I missed the whole flow restrictor part of the title. After I figured that out I noticed the valve wasn’t opening up for me. Then I realized that I plugged it in before the electronic pressure switch shut off. It needs to be spiced in between the Electronic pressure sensor switch and the booster pump (would have been nice to know). Other than that, it does make a loud hissing noise because of the pressure being squeezed through the restrictor, I welcome it myself so I know when the flusher and RO/DI unit are working and when their not. Just in case I can’t hear the booster pump rattling the stud I have it mounted to through the walls of the house.
