Getting the bike out of the garage this morning I noticed a weeble wobbling Budget barrel, full with my abbott clone, with the bottom pushed out. I released the cap and an amazing amount of pressure had built up judging by the noise and swirling dust in the garage

This happened years ago on the exact same barrel so I guess I shouldnt be surprised that the plastic must be weakened at that point. Hopefully it will have gone back to normal shape and the beer settled tonight by 5pm.
Which brings me on to some questions:
1. I change the rubbers on these regularly but that is to stop leaks -
Is it possible to test the valves as there must/should be some sort of safety release?
2. This barrel has had its last chance. I am looking for a replacement and the
king keg top floater has caught my eye (ouch). Has anyone got one of those and a budget barrel and if so how much wider are they as I have a custom built shelf which would struggle with anything more than an extra 7.5cm. also I guess they have the same valves so I can continue using my hambledon bard gas cylinder
