Fill the Bubbler Airlock with water and insert in drilled stopper or bung to vent gases during fermentation.
"Bubbler" style airlock makes a gratifying "bloop" noise during active fermentation. It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.
To use: Insert assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. The airlock cap should always stay on top when in use; it has several small holes in it that allow gas to escape but prevent the water inside from quickly spilling out if tipped or jostled.
Really like the large carboy and the airlocks fit well into the plastic lid, o more popping airlocks :)
Ordered brew kit and supplies and was very pleased with quality and promptness of shipping
Works great very good quality
The concept is great. The container itself is great. The screw top lid is great. The built in air lock and the lid seal... Not so much.
The problem with the original air lock is that I have trouble getting a good read on the airlock activity. Does it work? Yes, but not as visual as a 3 piece or S type air lock. That's why they started including a drilled stopper.
As for the gasket that everyone hates. Yes, it is terrible. Not quite sure the material, but it is too thin and not very durable. You have to tighten the lid to the point it is hard to get off later. Using two people helps in both instances. What was their answer to the problem? Make another lid that is a swing and a miss. The press in lid (only available as an extra purchase with the little BM until current stock runs out) also has troubles. First and foremost, it reduces head space by quite a bit. It also pops out by itself due to the design. The solution to that? Yet another "fix" that is available as an additional purchase. After spending twice the cost of the original fermenter, you have something that will reliably stay air tight.
The better solution? Simply replace the original gasket with a soft food safe silicone or other closed cell gasket material that is slightly thicker than the original gasket. They are pretty easy to make yourself if you know how to use scissors.
Whoever the designer is for these needs to learn the basic tenet of design. Most often, the simplest solution is the best one.
Oh, and some people have mentioned the bubbles in the glass. Yes, there are frequent bubbles. They were obviously made by the lowest bidder in China. As long as there isn't a crack or the bubble doesn't have a hole, it isn't really an issue. Just don't put scalding hot liquids in it or you run the risk of the fermenter breaking. Also, don't put them in the oven to sterilize them or try to boil liquids in them.
