Subject: Gas leak from posts seal at proper pressure?
|
Hi
I justed kegged a batch and noticed that there was some gas escaping
from the out post shortly after I connected it. But it seemed to stop
after a couple of minutes. I know that the cover truly seals when you
add the necessary pressure -- is this the case with posts/poppets too?
If not, I probably need to change the post/poppet. Any insight would
be appreciated. Thanks.

I have found that poppets don't always seat very well. Some do, some don't.
Cleaning them and any crud on the inside of the post where the poppet seals
can sometimes correct it. But many times I need to use a light sanitary
silicon lubricant spray on the seals before assembly the keg to keep slow
leaks like this from occurring.
In some cases replacing the poppets took care of my problems but usually
that wasn't the problem. It was crud or something, but using a light
sanitary silicon lubricant seems to have helped the most. Hopefully others
will have other tips to consider.

I also find that a good cleaning takes care of the problem most of the
time. If I find a poppet leaking a bit, I just depress it a couple of
times (watch out for beer shower!) and the leak usually stops
immediately. The next time I clean that keg, I take that post apart and
clean the gasket on the poppet with a rough washcloth. For the post
itself, I have a brush that looks like a miniature bottle brush (came
with my fancy turkey baster)which works perfectly for scrubbing the
inside of the post. I get all sorts of crud out of the post. I found
that most of my leaks occurred when I took out the poppet (or it fell
out) and I stuck it back in without scrubbing the inside of the post.
Apparently the misalignment between the imperfections in the poppet and
the uneven spots in the crud allowed beer to leak.

Thanks. Would attaching the quick disconnect with tap stop a small leak
in the post? I did this just in case and it seems to be maintaining
the pressure. So the question is, if there is a small leak in the
post, can attaching the quick connect seal it up (artificially)?

That depends on what part is leaking. If it's the poppet, then "yes" that
will stop the leak. If it's the seal around the post to the keg and dip
tube, "no" it won't stop the leak.

Yes. Having the QD attached basically bypasses the poppet. It forces it
to stay open, so that you no longer need it to seal. The seal then becomes
the responsibility of whatever the QD is attached to (faucet, CO2 tank, etc).

No, they shouldn't need pressure in order to seal. Do you know where it
was leaking from? IE, where it screws onto the keg, or where the poppet
depresses into the post? If it's just the poppet, sometimes they don't
seat quite right when you take off the QD and just need a little fiddling
with in order to seal. It could mean that the post needs a good cleaning.
John.
