Quick Overview

Why does BRS recommend this?


Float valves are simple to install and can save a lot of water from ending up on the floor.  They can be installed in containers as small 1 gallon pails, sumps, and 200 plus gallon commercial storage containers to shut off the flow of water.  Even if you do not have a large storage container a simple 5 gallon bucket with a float valve installed in it will help save money from having water end up on the floor or best case scenario just going down the drain.


Float valves are used to shut down your reverse osmosis system when the float is elevated. Float valves are typically installed on containers like large plastic food grade trash cans or other containers. Installation is as easy as drilling a small hole in the container, sliding the float in and attaching using the included nut.


Adjustable Float Valve - raise or lower the float valve.

What is your suggestion for a type of quick disconnect for this valve? Reason being is I like to fill smaller containers with the same line and would like to be able to disconnect the line without having to rely on the pinch fitting to hold up over the long term. thanks!
Question by: Chris on Nov 13, 2013 3:25:00 AM
Hey Chris,
The valve itself must use the compressing fitting so your best bet is to just hook up a short length of tubing and then use a quick connect union to connect the tube from the unit to your float valve. That will give you a quick and easy location to disconnect while not having to mess with the compression fitting. Better yet, you could use a 1/4" inline ball valve which is basically a union with a valve in the middle. That way you can turn the valve off, disconnect from the float, move it to your next container and open the valve back up.

How do you suggest hooking your reverse osmosis system to a storage tank that would lead to a kitchen faucet?

Thanks
Question by: Ryan on Nov 19, 2013 9:51:00 AM
Hey Ryan,
The best way to see how it all hooks up would be to watch this video on the 5 stage drinking water system installation. The setup would be basically the same for any setup might just be longer runs of tubing, etc. Give it a watch and if you still have any questions let us know!

Can I use this float as an ATO for my sump?
Question by: Sam on Jun 9, 2014 10:33:00 AM
Hi Sam,
If you wanted to use the float valve to control a gravity fed system it would work, though I would make sure your container is small as the salt, etc will likely cause issues with the valve in the long run.

I would not hook this up to an RO/DI unit into your sump if that is what you were imagining though. If the float were to fail you would basically be unleashing an unlimited supply of water into the tank!
Answer by: Bulk Reef Supply on Jun 9, 2014 10:33:00 AM
Once you set up your float valve and connect it to your Water tank(trash can) how do you disconnect it? Or is it meant to be a permanent connection? What I mean is once you put the tubing from your RO/DI unit(Blue) and screw it in. After you're all done, how do you tank the tubing(blue) out?
Question by: David on Apr 15, 2014 12:43:00 AM
Hi David,
The tubing connects to the float valve via a compression fitting. This can be removed so its not permanent but its not meant to be constantly connected/disconnected. If you have the need to constantly disconnect your RO unit from the float valve then I would suggest a push connect union, or better yet a push connect inline ball valve, which would not only have the quick push connect/disconnect fittings but for almost the same price also gives you the ability to turn the line on and off.

What is the max wall thickness that the valve can be mounted on?
Question by: Shawn on Feb 24, 2016 8:41:00 AM
Great question!
This will work on a maximum thickness of 3/8". Feel free to let us know if you have any further questions!

I bought the BRS RO/DI back in 2012.
The video mentions an auto shutoff and check valve that might be needed to stop the wastewater, but then it said that I wouldn't need them if I bought a BRS RO/DI.
One of the reviews said that they had to buy them for their BRS RO/DI.
So, do I need to buy an auto shutoff and check valve for my wastewater or is the float valve sufficient?
Thanks.
Dave
Question by: David Dolinoy on Mar 7, 2016 8:54:00 PM
Great question!
If your unit has an auto shut off valve connected to the red source water and blue product water line then you will not need the kit, rather just the float valve. I have included a link to the auto shut off valve for reference!

what size hole do i need to drill in my fish tank to mount this?
Question by: Joshua Hansen on Apr 3, 2016 4:37:00 PM
Great question!
The float valve will need 1/2" hole for mounting. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 6, 2016 12:31:00 PM
I am hoping that the answer to these questions will help me drill the mounting hole in the right spot the first time and also help me decide whether to get the adjustable or non-adjustable version.

When the non-adjustable float valve stops the water, where is the water line in relation to the hole you drill when installing the valve?

For the adjustable float valve, what is the range of adjustment in terms of the water line's distance above or below the mounting hole?

Thanks
Question by: John Moffett on Jan 23, 2016 7:26:00 PM
Great questions!
The float valves are able to be rotated slightly and the actual water level can vary depending on the placement and rotation of the float. The average level is within .25" of the center placement hole. The adjustable float can be changed over 5 inches in either direction depending on placement. Feel free to let us know if you have any further questions!

will this accept the standard 3/16" airline tubing?
Question by: Matt on Aug 11, 2014 7:02:00 AM
Hi Matt,

I would not recommend using anything but 1/4" RO tubing for use with a float valve. There is a potential for leaks when using soft tubing.

Hope this helps!
Have a great day :)

Hey guys... A few years ago I purchased a dual RODI system from you that auto fills the holding tank for drinking and fills the holding tank for my reefs by a manual valve. I'm finally tired of my main (reef tanks) tank overflowing because I forgot to turn it off. My question is, would installing a float valve on my big storage tank interfere with the operation of the drinking water storage tank?
As always, thanks in advance!
Question by: Burto on Mar 19, 2014 3:54:00 AM
Hey Burto,
It would not and is exactly what it is made for. I would still turn the valve off after you know your container is full to avoid the unit kicking on everytime a half ounce of water has evaporated, but the float is great to turn on and leave overnight as you don't have to worry about overfilling the tank!

  • Does the job By Nik on 4/29/2016

    This is a great piece of equipment does exactly what it's supposed to do. Don't set up an RO unit without one in your reservoir.
  • Simple to install By Andrew on 4/15/2016

    This was simple to install to our Brute trash can and gave us the peace of mind to know that the RODI system will shut off automatically once the container is full.
  • Great product By Brett on 4/1/2016

    As we used to say in the Navy: "Works fine, lasts a long time, doesn't rust, bust, or collect dust; fail safe!"
  • works great By adam on 3/2/2016

    works great and easy to install
  • Good Product. Saves RO water By JG on 2/17/2016

    I kept walking away and overfilling my containers. This fixes that problem.
  • Handy By John G on 1/26/2016

    This works great and saves RO/DI water. Shuts off and all I have to do is add prearranged amount of salt and test. Makes the salt water making process easier.
  • Don't forget the Check Valve By jsbull on 1/2/2016

    After I received this, I realized that the my RODI came with an auto shut off, but I also needed a check valve. After another $5 shipping and another week, it all worked.

    It really is great, just be sure not to forget the check valve.
  • Simple and functional. By Alan on 12/8/2015

    This works great as a simple mechanism to shut off my RO from the main holding reservoir.
  • Works great By Reef safe on 11/29/2015

    This is my first shut off valve so I don't have anything to compare this to. However seems to be doing its job without any problems
  • Excellent product!! By B on 11/24/2015

    Excellent product. The adjustable float valve is well built and fits 1/4 Polyethylene tubing perfect. Installed with no problems and no leaks. I purchased this product along with the BRS 4 Stage Value Plus RO/DI System - 75GPD. For the price it is well worth it.
  • RO Cutoff Vavle By Ballec2 on 10/4/2015

    Easy installation, and works great! Had 2 previous events with RO overflowing after forgetting to turn off. Since installing the cutoff valve to there hasn't been anymore accidents.
  • Works great By MDM on 8/7/2015

    It works just as described. It took some creativity to mount it on my undrilled tank (I had a spare 45 gallon aquarium to use as a water reservoir). But I was able to work it out.
