Must have in kegging

Review by STEPHEN HAMILTON on 9/3/2018

I can't count how many times I was force carbonating, and beer goes back into the CO2 line. This solves the problem. The key is this check valve goes right on the ball valve, so there isn't a way for liquid to come out of the gas line. I had one at the regulator, and with enough pressure liquid still creeps up. I have another one that works, but since this is clear you can verify that you aren't having any seepage! Great product!

Quality Check Valve

Review by Kris Walker on 11/2/2018

I have found this to be very effective in preventing liquid into the gas tubing. However, my only issue is since it is a pressure release...it does not measure the pressure in the keg as well as a non check valve system. An issue I wish I knew prior to ordering.

Must have

Review by JS on 1/24/2020

I have a 4 tap system and because I force carb I was getting beer back into my gas lines which over time made the lines skanky. When I rebuilt the gas lines I added these as $10 x 4 is cheaper than the time it takes to rebuild the lines. I wish I had thought about these when I built my keezer. Love Williams Brewing, always great service.

High quality in-line piece

Review by Eric on 5/14/2020

I can't say I've experienced backflow, but looking into my keg coupler, the thing prevents backflow is a flimsy piece of silicone or something similar. So if this keeps any issues from occurring and dirtying my gas line, I'm all for it at the price point.
