Were any of the pins out of the braces?
Did all the braces ring alike?
Did not some of them sound like a fiddle-string?
Did you notice any scale on flues or crown sheet?
If you did, when do you intend to remove it?
Have you noticed any evidence of bulging in the fire-box plates?
Do you know of any leaky socket bolts?
Are any of the flange joints leaking?
Will your safety-valve blow off itself, or does it stick a little sometimes?
Are there any globe valves between the safety-valve and the boiler? They should be taken out at once, if there are.
