3-Way Ball Valve with
John Guest 14" Push Connect

SKU: 206000


  • Well worth the price By David on 1/14/14

    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 12/30/13

    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 12/9/13

    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 8/13/13

    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 7/5/13

    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 4/19/13

    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 4/16/13

    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 10/31/12

    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 7/18/12

    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.
  • Di saver By Christian on 4/19/12

    Bought this to prevent tds creep from destroying my di resin prematurely. Works perfect but pricy for this little thing, although it will pay off not having to buy di resin earlier than needed due to tds creep
