  • A 'must have' item By Sportfish on 4/25/2014

    BRS has the best prices on RO/DI machines and I have their 5 Stage 75 gallon/day system. I LOVE it. I of course got it for the FOWLER tank I have - it does not take long to get tired of going to a 'storefront' FO/DI machine and lugging 5 gallon jugs around. I then started using the water for drinking and some special plants. But certainly the plants don't need DI water, and while I'm not convinced of it, I've read 'people' should not drink DI water (I need to keep researching this). So the solution is to install this valve in between the RO filter (my State 4), and the DI filter (my Stage 5). It took seconds to do and now I can - with a simple twist - generate either FO/DI water, or, just exceptional filtered RO water - saving / extending the life of the resin significantly. And you can look all you want, but even at what seems an expensive $19+, BRS has the best price on the valve. And you can try using shut-offs and "Y" fittings that appear to be a cheaper solution, but in the end and for a couple extra bucks, you get this 3-way, have a very 'clean' installation, and you're done. BRS sends quite a lot of hardware - expensive hardware - with their systems, and it is appreciated. But for me, a lot of it was not needed and inapplicable. I would respectfully suggest that BRS omit some of the 'other' hardware - much of which many will never need/use - and instead include one of these 3-way valves which I am certain EVERYONE will need and use.
  • Well worth the price By David on 1/13/2014

    It seems like a lot to spend on such a small bit of plastic valve, but when you get it in your hands the high build quality is obvious. Solid feel and overall larger than I'd expected.
  • Push to Connect.....and Viola! By Tommy Gee on 12/30/2013

    I purchased this John Guest "push to connect" 3-way ball valve for two reasons:

    1.) to direct my start-up RO water flow away from my DI filter (to prolong the resins useful lifetime).

    2.) to avoid contaminating my DI filter when I back-flush my RO membranes

    Does it work?

    Like a charm! Now I can be assured that the inflow of RO water to my DI filter will help me achieve my goal of increasing the life of my (more expensive) resin.
  • Expensive but a must have By BobbyT on 12/8/2013

    I use it to shut off my DI canisters when I'm flushing the system.

    That small amount of TDS being pushed through the DI, can destroy the resin pretty quickly. It's best to shut it of
  • Excellent Valve that works as intended By DrewHase7 on 8/13/2013

    I added this in between my RO tank and my DI cylinder. I use this to make a bit of RODI water when i need it for my tank, but can shut off the DI unit when i want to fill up my drinking water tank for normal use.

    This allows me to not need a check valve, as I will rarely ever need to be making DI and drinking water at the same time. No leaks.
  • Overview of Diverter Ball valve By PJ on 7/5/2013

    Works as its suppose too.Make sure when you install this valve that
    the single input is where you connect to your water line.And the
    two inputs are your diverters.No leaks.As of yet!These push in valves
    are simple to use.
  • Extra Water Tap By Richard on 4/19/2013

    Added this valve to the output of the carbon filters, but before RO, so I can easily obtain clean drinking water with out using the DI. Very easy to modify the system and install this valve. Don't know what people did before this type of valve was used. No leaks and easy to turn with any water pressure.
  • Great product By Milkman on 4/16/2013

    I use this right before my DI cartridge so I can pull drinking water from my RO to refill my bottled water.

    Agree its pricey, but saves me a lot of time and mess disconnecting RO lines.
  • Pricey but worth it for the long term benefits! By William on 10/31/2012

    When I saw that I was passing over 100 TDS water through my DI cartridge the first few minutes of usage this valve was a no brainer. $20 might be hard to swallow at first but the long term value can't be beat to avoid TDS creep and how it will exhaust your DI resin. This is a must have for your RO/DI unit.
  • Time Saver When Changing Cartridges By Pet Store George on 7/18/2012

    I used to disconnect tubing to reroute water to the drain to flush new cartridges. One time, I did not connect the tube correctly and the slow leak made quite a mess. I now use one of these to switch the water to and from the drain to make cartridge flushing much quicker.
