Those QDs are all pretty much all the same and should last many, many years.
The ones with CMB (CM Becker) embossed along the top flange are known to be among the best.
The top cap (there's a screwdriver slit in it) comes out for cleaning and servicing (the small) parts inside. Make sure it's screwed down tight.
You got to find that leak. It's a matter of systematic search and elimination.
If your disconnected keg loses all its pressure over time it has a leak.
There are many threads and posts on finding (hunting down) CO2 leaks.
There's a flat o-ring under that cap making the actual seal with the body of the QD.Found it.
It was almost continuously bubbling.But... one little bubble? How often?
No, not going to bother. I am confident this was my problem. Like I said before, I was careful to check everything but the QD. When took the QD apart I found the o ring was chewed up. Must have gotten caught in the threads when the QD was assembled. Luckily I had a spare o ring. Popped it in, tested it, and set everything back to normal.Have you weighed the tank yet?

Are you saying that you put that into use without sanitizing it first?

Make sure it's in there and not deformed. I don't think you can over-tighten that cap, so nice and tight should do it.

There could be other leaks. hose connections, etc. You can stick that keg upside down in a bathtub or large sink if it comes to that.
Also make sure the connection of the regulator to the tank has a seal in it. Can be a rubber, nylon, or fiber washer. The large connection nut should be tight enough too.

QDs that look like the common black and gray CMB ones are all built alike. From what I gather the CMB embossed ones are original, and generally better quality and mostly trouble free. Now quality may vary among "generics" from other manufacturers'. I had an off-brand one that was a bit wobbly when mounted on the (liquid) post, but worked fine otherwise. I make sure i get genuine CMB ones.I've got a mixed bag of ball lock QDs from different sources and had noticed that the Becker variety have that slot in the top but never bothered to think that it actually had a purpose.

Just checked, and sure enough it's a Becker QD. Hopefully that'll be the root of the problem.
I can't see that coming from the QD.For the last few months I've been getting foamy pours (at the beginning of the pour only, after it sits idle for a day or more) from one of my taps. I tried a few of the hacks listed elsewhere on the HBT site without ever finding a satisfactory solution, and finally just learning to coexist with the annoyance by dumping out the first ounce or two from that lesser used faucet.
After a keg has been sitting idle for a length of time, any sediment (from suspended yeast usually) will pour out first, yup.Question sort of related to this topic: I just kegged a brew last weekend. This is only the second one i have ever kegged. I read somewhere that some people tend to toss the first beer or so out of the keg stating that things sort of settle in the keg and come out in those first pours due to the dip tube sucking that stuff up first. Is this common practice? I don't feel like pouring out any of my precious home brew if i don't have to, but i also want that first beer to be tasty as hell
Brewing Classic Styles has solid basic recipes for about any, well, "classic" style.My next brew will be one of my own design fitted to the old ale style. I plan to try adjusting the water profile on this one, and mill the grain myself.
