Ball Valve for The Catalyst Fermentation System

Makes sampling so much easier. Could use it to bottle if you had a lot of trub at the bottom, but I still just unscrew the mason jar and put on the bottling attachment. I think this generates the most yield. I had to cut a hole in the carrier to make this valve fit, but besides that, easy enough to install with fairly basic equipment.

I love it as long as it does it's job everything will be great

The valve is very well constructed, quality materials, reassuringly solid. However, installation was not easy. Drilling the hole can be a bit awkward given the shape, location and material. I came in on a slight angle and so had a small gap between the tap and the edge of the hole. The provided O-ring for the interior deformed under tightening preventing a seal that could cover the gap. I ended up buying some plastic washers and using plumber's tape to get everything sorted. Had to fill and empty the fermenter with water a few times until I was able to feel confident there's no leaking. It was a bit of trial and error.

this is a must. makes it easy to taste, measure, remove your brew without disrupting or stirring up your brew. glad I made the purchase

So glad I went ahead and purchased the ball valve at the same time as the Catalyst. Great clear beer from the beginning of the bottling process. Also easy to take a sampling.
