I did the normal draining procedure to my boiler last night, and afterwards there was loud bangning of the pipes. When I went down and looked, the boiler sight glass was full (normally I am told it should be 1/3 to 2/3 full). This morning water was leaking out the bottom of the sight glass near a small vavle opening. I am assuming that the boiler is flooded.How did this happen and what do I do?
