Excellent timing..
I could NOT have asked for a better birthday present :).
However, I must plan ahead. This is in a country where the water supply comes into houses at such a pressure that in its regulated down form it still hits 6 bar (87 PSI). In the UK it tends to average at approx 0,7 bar (10 PSI), but it's easier illustrated: a fully flushed toilet water reservoir refills in under a minute :).
It thus stands to reason that that pipe isn't going to be subtle about pressure either, and making a hole may result in a flow of beer that even a born and bred Glaswegian cannot keep up with.
But it would be fun to try :)
