Jimmy only seemed vaguely interested as the safety valves were tested. They worked fine, although bringing a steam boiler to enough pressure to make the safety’s lift is always feels like something I should viewing on CCTV rather than standing on top of the boiler tightening bolts as is hisses angrily and vibrates with enough pressure to level the building. But, that was that: cuppas and home to try and sort the tools out. Although what actually happened was they got thrown into the workshop to get sorted “later”.
