Boiler leaking.....

Our lovely (not that old) combi boiler sprang a leak recently. I got fed up with waiting for our plumber friend to phone back so I decided to fix it myself. Found a service manual on the net and after figuring out where it was leaking from I discovered there was a rubber washer to blame. Quick call to the 'Service Centre' for parts and the entire thing cost me £12 and took 30mins. K was somewhat aprehensive when I started hammering stuff, removing large bits of metal and draining off water but she soon calmed down :) It apears fixed but will give it a couple of days before passing judgement. So, next project, anyone know how to move a radiator....
