So, 2 days ago I put the Coopers Irish Stout in the wilko pressure barrel. And today I went to test it, not because I ever thought it ready but more to check the pressure & thankfully it may well have saved the batch. First draw, no pressure at all and even slowed to a trickle as I filled the half pint glass, this is despite adding more than enough sugar for priming. OK, I know it would never be lightly carbonated after 2 days, but more a pressure test. So I then added 1 of the 8g C2o bulbs to then hear pressure leaking from the lid!!!, wtf, as tight as, pre coated with Vaseline and the barrel thread PTFE tape wrapped. Then tried loosening, no movement (so oh **** locked the thread) to get slight & slow movement opening to note the original mark. Then tightening again to get to the same point and barrel slides on surface so thought screwed up somewhere!. Then putting more effort in I get maybe 3 cm tighter from original position.
Then I add a second Co2 bulb to then hear gas\pressure coming from the valve this time and not the lid. Bloody hell maybe a dodgy valve!. Then think, well plenty of priming sugar & a second Co2 bulb so draw a glass, Jesus, sprayed the bloody wall such was the pressure. Tried a second (half pint) glass & then a third to get the hang of the pressure. So, it now after a tweak, looks to be retaining the pressure and pulls a decent glass.
The Wilko pressure barrel is basic, but with a little testing and work is decent and seems to do the job if you work with it and get tighter thank you think the lid can go.
