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.

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.

  • 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

    Great product, well built.
  • Excellent By Robert on 2/13/2015

    Very well built and quite secure. Used it as many others do and use it to divert the ro flush away from my di resin.
  • Great valve to save DI resin By Justin on 1/22/2015

    I bought this to get rid of the TDS creep on my DI resin and avoid any backflush from getting to the resin.

    This is a very high quality valve and really when you think about you are getting a 3 way valve for $20. The big box store single valve cost close to 10 and is not nearly as nice and much more prone to leakage this this one. Thinking about adding a second to be able to fill to water tanks rather than pumping from one to the other. Well worth the money.
  • Great Product By Romain on 12/14/2014

    I use this on the water line after the RO canisters before it gets to the DI section to fill my homes drinking water. Super easy to install(gotta love push connects) and works great I agree a little pricey but saves a lot of time so well worth it.
