The silver soldered copper boiler has had a hydraulic test with new certification issued. The safety valves accumulate and will require servicing or replacement to pass a steam test. The injector works although is a little fussy, requiring careful balancing of steam and water to operate, the hand pump proved a reliable alternative.
The regulator is "all or nothing", which - whilst it works - would reward further investigation.
