I do not follow what "Trefoyl" means by "can’t hold back high pressure all at once" though? (Can you enlighten me please)?
I let the pressure out of the keg by lifting the safety valve before connecting, otherwise beer will rush up into the gas hose. When that happens the excess gas pressure dramatically hisses out which is very startling. Then I need to replace that section of hose, so it’s a mistake I don’t repeat very often.

I would not recommend buying this model from the US, wouldn’t the pipe thread be different? Not worth the trouble and expense.
Ah … thanks. Good point about threads, US use NPT not BSP so getting adapters will be more difficult over here (and at 1/4" the two threads are not even closely compatible).

That process is "venting" and needs to be done to any "cask" style beer before serving, can't avoid it really. I try to simplify it using "bubble counters" (see my article and the piccies in this thread*). The trouble with using the safety valve is it's too quick and the pressure will probably just build again as gas comes out of solution. The other problem using the safety valve is you might overdo it and pop the Corny O-ring seals.



And before I get any fingers wagged at me: I know Corny kegs are not ideal for this purpose, but they can be made to work.


(EDIT: *Oops, sorry, piccies not in this thread but the thread I linked earlier in this thread).

One of the reasons they I always purchased “new” (I did buy some that were 2 years old but essentially as new) corny kegs, once you have fettled about with them, replaced parts and lost a batch or two are the second hand ones really significantly cheaper?

Not any more they're not! I think the first Cornys I bought were about £20 eight years ago. The second-hand ones will run out - there only seems to be one design left now (but seemingly plenty of 'em).

What did you end up decided for this setup? Corney kegs or polypins/cubitainers?

For me …

There was no "deciding". Polypins could not answer my storage requirements (I could not operate my brewing within the "shelf life" they impose). So a few years ago I invested the time and money into developing that article I wrote using Corny kegs because I couldn't find good write ups from anyone else using Cornies (or any other keg, or not that I could approve of) and I already knew "breathers" and the "poor-mans" version using 37mbar LPG regulators with kegs didn't leave me any better off - perhaps worse off - than using polypins. I did try using 37mbar LPG regulators with Cornies for a while because some people reckoned it worked; didn't for me, which sparked off the search for why and hence the article.

EDIT: The article referred to:
