Have I damaged the boiler of my "Lady Anne"?

Safety valves seem to "feather" constantly.
I heard somewhere that this is a deliberate policy.
It is considered preferable, safetywise, to "pop" valves.
 
Doesn't sound like much water escaping from the safety valve. I'm at a loss to explain where it's going.

@zingyorange - with Roundhouse (at least with my Russell) I find that the safety valves blow off however much I turn the gas down, and even after a fairly lengthy run; I can't see any obvious way of stopping this. Maybe others know better?

I fitted a DJB whistle to my Silver Lady which helps a lot. It is difficult though

Hard to say whether it is faulty or not. These valves are designed to feather initially and so if you are running close to working pressure then they will. if however it is feathering at 20psi then there is probably a bit of dirt in the valve. You could try gently lifting the central pin whilst in steam to blast it out, then let it drop to shut off. This should clear the valve. If not get a new one, fit that and take apart and clean the old one. This way you will learn how it works and will always have a spare...

I prefer pop valves ? most do ? but the H&S implications of a sprog getting a facefull of steam is probably what prompted the changeover. You can however, with gas firing, lose half a boiler of water with a 'pop'.
