Boiler leaktest options?

TomM

I have a Crown DS405(c 1989) steam boiler. Its losing like 1-3 gallons or more a day. I checked diligently and found no leaks whatsoever, and all my vents are closing properly (two pipe air vent system).

I'm thinking that maybe water is leaking from the boiler into the flamebox (is that what it's called?) and vaporizing out the flue.

.

What are the methods to check if your boiler is leaking internally or not?

did you flood the boiler

i've heard people mention flooding the boiler (while off) way above the NWL. and see if you get any puddles then.
