- John Guest Angle Stop Valve
Why does BRS recommend this?
If you constantly need to install and uninstall your RODI system up to your sinks feed lines then we highly suggest using the John Guest Angle Stop Valve. With metal connections repetitive installs and removals will not cause issues like plastic may sometimes. With a simple ball valve you can also shut the feed of water off to the RODI system while keeping water flowing up to your sink.
John Guest Angle Stop Valve's directly connect RO units to the household water supply. It installs under the sink, inline after the shut-off valve. This clean, out of the way installation leaves faucets free for other use. To turn of water supply to the RO unit for maintenance simply close the ball valve.

Get this if you plan on hooking RODI under a sink By Brock on 12/6/2019
Brock would recommend this product to a friendI bought an RODI system and it came with the plastic adapter for under the sink. It should really come with this. The plastic ones strip so easily when being attached to metal. This was plug and play easy. -

Great non-permanent RO/DI connection By Kyle on 5/2/2017
Kyle would recommend this product to a friendThis valve is a great way to connect an RO/DI unit to the cold water supply under any sink without making any permanent holes in your plumbing. This is much better quality than the ones you find in hardware stores. I highly recommend this valve for anyone looking to plumb their RO/DI unit under a sink, have the luxury of disconnecting it when needed, and being able to simply turn a valve and start making RO/DI water. -

very good By babnika on 7/14/2015
babnika would recommend this product to a friendI really like the way this valve swivels around the stem making routing lines a lot easier. Not like others that can't that I have used in the past. I have two of these hooked up to one line to feed two of my RO units . verry impresed -
So-so By GRC on 10/1/2014

Works without problems By Nish on 10/2/2013
Nish would recommend this product to a friendAs a new reefer, I didn't know much and a friend suggested this, I searched this product at the homedepot and lowes or weeks as I didn't wanted to pay or shipping. But I couldn't find it. Then I ordered this with few other things I needed.
This product is well made, even better than the name brand stuff you can buy at lowes. Worked great 2 mins installation an I was up and running. -

Great Adapter By Justin on 2/2/2012
Justin would recommend this product to a friendThis adapter worked perfectly under my sink. No leaks and I am able to easily adjust the PSI for my RO/DI system. Much better than the saddle adapters!
Will this fitting work on the cold water side of a washing machine water line?
Question posted on May 11, 2017 11:13:00 AM
Hey there,
These valves are designed to connect to standard cold water connections in 3/8", which are typical of sink lines, but washing machines may differ from this.
Have a great day!

Why are there two sizes? What size works for a standard sink feed line?
Question posted on Mar 16, 2018 4:55:00 PM
The different sizes available only matters for the size tubing your RODI system uses. The fittings that connect to your source water are the same for both.
