Had it happen once before on a light blonde ale and it was fine so not too worried. If any off flavours due to oxidation showed up I would have thought they would have been obvious in the blonde but none showed. All beer is happily on CO2 once again and I am replacing a faulty poppet valve that was responsible for the leak. I will report back on beer quality once carbonated.XXXXX wrote:It should be fine. Refrigerate it if you can otherwise keep it covered. It's certainly not best practice but 14 hours won't hurt it. Or shouldn't
I'm not sure I understand what you're saying here. If you're talking about ball-lock connectors, the quick-disconnect fitting (the one that clamps to the gas or beverage line) has a pin in it that pushes the poppet down, allowing the liquid/gas to flow through. It doesn't just rely on pressure. If it did, then when you dropped the pressure to, say, bottle some beer off of the keg, the poppet wouldn't allow fresh CO2 to flow in. The posts and fittings are designed so that when the (spring loaded) pin in the quick disconnect is fully depressed, it still protrudes enough to press in the poppet on the post.bellybuster wrote:Just watch those replacement poppets, some of them have a really strong spring and won't allow pressure through. If you get one of those just clip the spring a tiny bit.
In pic 4 i connected the post to the connector and pushed the sharpie up as far as the pin in the connector would let me with about 100X more force than any poppet spring would have ( because i am powerful obviously ) and then i marked the line. the distance is approx 1/8" or 0.122" short of the first line. That means that without a shadow of a doubt that when the balllock is locked onto the post it has to depress the poppet open 1/8" and even more so of the spring is not as strong as me, which is more than enough for gas or beer to flow around.
For the gas side it does not matter how much compression the poppet gets as long as it depresses. Two springs are at work fighting for compression space in a fixed axis. Gas will reach an equilibrium as long as it has a path to get in faster than displacement of the volume being removed from the vessel. It does not matter which side wins, as long as both give in a bit.
The beverage side is a bit trickier. Not enough compression will cause turbulence and knock co2 out of suspension. Or a total blockage of beverage flowing. The viscosity of beer is much higher than co2. Ideally the spring will depress > 3/16" ID, so your beverage line is the greatest restriction variable (and a known value). A smaller bottleneck in your system will likely cause pouring issues. (Foam,flatness,pressure washer etc)
Universal poppets work on any keg that does not have nylon inserts. They do have a caveat. The spring may need to be reduced if the disconnect spring can not over power the poppet spring. This can be due to tensile strength or compression space. This is more of a mechanical tweak and not a product issue. Kind of like how windshield wipers have multiple brackets in the pack.
