- 3-Way Ball Valve with John Guest 1/4" Push Connect
Super Useful By sazoram on 10/3/2014sazoram would recommend this product to a friendI use this to keep my RODI unit pumping out the pure H20 while I can control the output to two repositories. Would otherwise require two ball valves and a Tee. In addition, two ball valves would run the risk of shutting off the continuous supply which would cause my RODI to cycle.
A 'must have' item By Sportfish on 4/25/2014Sportfish would recommend this product to a friendBRS 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 1/14/2014David would recommend this product to a friendIt 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 12/30/2013Tommy Gee would recommend this product to a friendI 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 12/8/2013BobbyT would recommend this product to a friendI 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 8/13/2013DrewHase7 would recommend this product to a friendI 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 7/5/2013PJ would recommend this product to a friendWorks 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 4/19/2013Richard would recommend this product to a friendAdded 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 4/16/2013Milkman would recommend this product to a friendI 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 10/31/2012William would recommend this product to a friendWhen 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 7/18/2012Pet Store George would recommend this product to a friendI 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 4/18/2012Christian would recommend this product to a friendBought 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

Previously Asked Questions
by David on April 28, 2014, @6:31 PM
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.
Bulk Reef Supply 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.
by Thomas on March 29, 2014, @8:50 AM
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?
Bulk Reef Supply 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.
