Quick Overview

Why does BRS recommend this?

The 3-way ball valve is probably one of our most favorite fittings.  By swinging the handle from one side to another, you can either turn water flow off completely, or direct it from one direction to another.  They work great for fresh and saltwater storage containers, and give you control of when the container fills back up.

Product Questions

I read reviews how this can prevent using up all the DI prematurely on start up and when back flushing the RO membrane. Where in the line does this normally get installed?
Question by: Thomas on Mar 29, 2014 8:50:00 AM
Hi Thomas,
The first bit of water that comes out of an RO membrane when it starts has a higher level of TDS (called TDS creep). People use this valve on the line between the RO membrane and the DI resin so that they can divert off that first gallon or two of higher TDS water.
Answer by: Bulk Reef Supply on Mar 29, 2014 8:50:00 AM
I have the 4 stage Value RO/DI unit. I was wondering, would I need this if I wanted to split the blue water line. So that when I wanted to make RO/DI water for top-off, then flip the switch for when I wanted to make RO/DI water for my saltwater tank. Connect this to the end of the blue water line, then connect the tubing to branch off to the respective tanks. Is this what I would need? Thanks.
Question by: David on Apr 28, 2014 6:31:00 PM
Hi David,
You wouldn't need this valve specifically but it would be a good option. Otherwise you could use a tee and a pair of inline ball valves (one for each line) as well.

  • Just installed this on my new RO DI... it's not working By Stephen on 9/30/2015

    I may be doing something wrong, but it's seeming more that I have a faulty unit... water will only come out the bottom... first thought the DI was the problem, but tested the main line of the "tee" by disconnecting it from the DI and have the same problem. Would like to know if anyone else came across this and if there's something I need to do differently. Thanks... I gave it a three because I had to pick a star... hope to be saying five stars once I figure this out.
  • Good quality By Kathryn on 8/31/2015

    I got this to work with my RODI system, to switch between drinking and tank water. It is well built and easy to install. I have no doubt this will last a long time.
  • Great Valve For Diverting RO Line By Jon on 7/20/2015

    I mainly got this valve to divert product water line when flushing the system instead of burning through resin when flushing the system. If you going to do the same as I did I would recommend by an RO tube divider to connect your waste water with the diverted product line so when flushing the system there isn't two separate lines being used and it's a lot more neat and tidy.
  • Perfect By Joshua on 7/10/2015

    got this for an rodi system to switch between ro water for drinking and di water for fish tank works great no flow back between directions and no need for check valves like you would need for a standard valve
  • Perfect for my application By Scott on 4/16/2015

    I used this valve to divert the first few minutes of RO water to waste to help save my DI resin. Very simple to install and works perfectly.
  • Sturdy and smooth By Burto on 4/9/2015

    Great quality product. I bought this when I changed out my media in my RODI unit. Instructions that came with the new membrane said to discard the first hour of product water. I didn't want to throw away the 60 gallons or more of the water I'd already made, so I added this little tap. Now, I use it for a lot of things. Whenever I just need a little RODI, I switch the valve and I have a controllable flow. Works great!
  • great product By Josh on 3/31/2015

    This fitting is awesome so I am not burning Thur di resin when I first turn on my system.
  • Well Built, Easy to Use By Linda P on 3/17/2015

    It's made of sturdy plastic that I expect to hold up for quite a while. Better than I've seen in local stores. Easy to use. Just cut the water line squarely and push in then pull backwards a bit to make it grip the hose. Flip the toggle to have it run through whichever side you need. It allows me to fill my storage tank or my sump.
  • Does the trick for me By StarFishMan on 3/2/2015

    This allows me to easily throw the RO/DI water out to a 1 gallon milk container to be used for drinking water. Without having to swap anything. Just works and comes in very handy. I can think of several ways to use these.
  • Very handy By James on 2/23/2015

    Good for many uses and good quality.
  • Ball Valve By Utah Reefer on 2/18/2015
